Protection and prices to buy farm machinery depends
Agricultural machinery may cause harm to human body parts , there must be protection measures. This is the national compulsory standards . Therefore , buy equipment , be sure to choose those with reliable protective measures to relieve hazards and have a warning label products . This will not only use them at ease , but also to avoid personal injury accidents. National mandatory standards , safety of agricultural products must pass a safety protection device. Like the initiation claws, fan , pulleys, PTO shaft , liquid sprayer exhaust pipe , chain drive and the knife shaft assembly parts and so have shields . Pedals should be skid plates, easily hurt in the place you want to paste the yellow or red warning signs . Throttle, Dangba other places, have a significant operation symbols. During use , if damaged safety devices , hand sprayers do not take it lightly , should be put on the purchase of new guards to avoid security risks planted .
To see prices
Select agricultural products , according to their affordability and functional needs, appropriate to compare prices. The same types of products such as the price is too low, the quality of such a machine is often difficult to guarantee. Similar products, the proposed purchase of the medium price range . Same brand , model products in the exclusion stock machine, repairing machines , under the premise compare dealer , you can choose a relatively low price products.

With a reasonable power to buy farm machinery
Power matching the power machine mainly refers to power and speed to meet the needs of mechanical support . Power is to describe how much mechanical work done per unit of time , expressed by kw ; speed is the rotational speed of the power machine shaft , commonly r / min expressed .knapsack power sprayer The size selection is based on the power machine power production machinery needs identified . If the power machine rated power selected too large, will increase investment costs , big horse cart wasting energy ; rated power if the power machine choose small, appeared with fixed or overloaded , damaged power machine , shortened life expectancy and even damage the power machine . Therefore, according to the actual needs of production machinery and working methods , through scientific calculations, in order to select the appropriate power machine power . For the province , generally small-scale farmers to choose the power machine , the selection according to the following criteria : If agricultural production machinery and the motor is a direct drive , the selected motor power should be dragged mechanical power of 1.0 to 1.1 times ; if agriculture machinery and motor is the result of belt drive , the selected motor power should be dragged mechanical power of 1.05 to 1.30 times ; engine supporting agricultural machinery should be equal to the power required 1.3 to 1.5 times. Optional powered farm machinery required speed as much as possible with the speed of the same or close , because it can be installed directly used agricultural machinery , because speed is inconsistent, in order to meet the requirements , you must refit the transmission equipment, fruit tree sprayers increase the number of charges .
If there are some agricultural households power equipment in advance , it should give full play to the role of existing power machine , in the purchase of new agricultural machinery , we should try to consider power machine capable of matching the original , except for special needs , in general, do not each machine is individually furnished one kind of power machine , so that it costs too much, management is not easy .

Four coup spring wood furniture to help you achieve pest
pring, the weather is warming, if the home with wooden furniture, be careful to start a variety of active worms, oh. The following recommended several ways to help you overcome "Zerg."
After the renovation or insect chemical sprayer spray water as much as possible, buy pure wood furniture must ensure through pest control treatment. Spring and summer, when you open the window preferably with mosquito nets.
Paint handling. Have not yet been victimized some corners, with raw tung oil, shellac or varnish coating, brush the surface of lockers, so moth isolated from the air, to achieve the purpose of moth.
Pharmaceutical treatment. When the lockers are moth damage, the available dichlorvos and water ratio of 1:5 dubbed liquid,back sprayers spray with a sprayer full, so that the liquid penetrate inside lockers, to a continuous jet 3-5 times.
Diesel rubbed. Clear the infestation has been placed in lockers at sunrise, with a brush or cotton dipped in diesel will all lockers painted again.

How hot season only reasonable use of pesticides
Safe use of pesticides has been a concern for farmers, but in the actual production but has not been brought to our attention, blind medication continues to occur, resulting in a serious waste pesticides, injury occur frequently; while for applicators is a poison , especially in the hot season, which is even more prominent. For this reason, to remind farmers rational drug use.
First, improving the utilization of pesticides.
Attention to increase adhesion agents. Outdoor use of pesticides should be selected crops resistant to rain erosion, cream and other more appropriate surface residues of these pesticides on the plants longer, whereas powder, liquid, etc. are relatively poor. Many crops, there blade surface or thick hair wax layer, such as corn, onion, ginger, taro, etc., the liquid in the hair, easy to form droplets on the wax layer, can not fully contact with the surface of plant leaves, can Silicones in pharmaceutical and other additives added to enhance the pharmaceutical effects.
Second, appropriate to reduce the concentration of drug
Most of the efficacy of pesticides as the temperature rises, the efficacy will be enhanced, so the hot season medication should be taken to minimize the amount of liquid, especially pharmaceutical hormones is particularly note the dosage weight can easily lead to injury of happen. Therefore, according to changes in temperature reasonable adjustments pharmaceutical concentrations.
Third, pay attention spray quality
In fact, during the drug crop spraying, the crop can be attached to the blade surface pesticide droplets is limited, when the pressure sprayer spray volume exceeds a certain limit, the leaves on the tiny droplets will agglomerate into large droplets and rolled down, the loss, but the blade attached to the lower amount of pesticides. General requirements for aerosol spray droplet mass distribution, high coverage to wet the surface does not drip appropriate plants, thus requiring the use of spray atomization effect, reduce the liquid waste. Note also that a comprehensive spraying, especially some of the pests prefer spawning in the dorsal damage, especially when spraying agent attention.
Fourth, a reasonable spraying to prevent poisoning
Pharmaceutical, pesticide spraying to prevent corrosion of the skin, the use of volatile pesticides must pay attention to the use of masks, while prohibiting the midday heat in summer time household sprayer spraying pesticides, spraying should be selected in the summer before 9 am or after 4 pm, to avoid injury place. Continuous application time not too long.

Water mist application conditions and requirements
A water mist extinguishing system should be refillable water containers clean and fresh water. (Commonly used industrial distilled or treated potable water)
2, the protection zone structure and the doors and windows of the fire resistance of not less than 0.50h, the ceiling of the fire resistance of not less than 0.25h. (This is to prevent the spread of fire outside the protection zone into the protection zone, thus requiring the protection zone of the wall and the doors and windows should have some fire resistance. While requiring the issuance of extinguishing fire to a period of time, building components will not be damage to ensure airtight protection zone, does not cause loss of extinguishing agent, affecting fire effect.)
3, before the start of water mist fire suppression system and the set fan, smoke machines, blowers and pipeline fire damper, smoke damper should be closed automatically. Staff confirmed after the fire should start the smoke machine smoke. (This is because to a protected area being ventilated water mist extinguishing agent release, fire extinguishing agent as soon exhaust air outflow protection zone, the protection zone to reach the design requirements of fire extinguishing agent, seriously affecting the extinguishing effect; another , fire protection zone may also spread through the air duct.)
4, water sprayer mist extinguishing system, you must cut off the fuel, combustion gases of the gas source. (This is to prevent fire expand, to prevent dilution agent discharge strength, impact extinguishing effect.)
5, the nozzle head and nozzle bottle plastic sprayer spray angle between the object of protection should not be within the scope of obstructions. (This is because the memory in the range of the jet nozzle obstruction, will seriously affect the jet effect, which affects the extinguishing effect.)
6, the protection zone should be used doors fire doors open in the direction to evacuate, and can automatically shut down. (This is to prevent the door open in case of emergency, the impact of evacuation. While requiring evacuation door can be automatically shut down, in order to facilitate the protection zone of water mist fire extinguishing water to maintain a certain strength to prevent the loss of extinguishing agent, impact extinguishing effect can be avoided for some reason the person trapped in the protection zone, from the protection zone to open the door smoothly evacuated. protection zone automatic closing doors design, emphasizing when the door is closed, on how circumstances can open from inside the protection zone.)
7, water mist fire extinguishing system equipment should be set at an ambient temperature 4-50 ℃ dedicated equipment room. (This is because the temperature is too low, the water will freeze, the temperature is too high in the tank water temperature, resulting in vaporization and heat exchange, and may have a scale affect water quality. Settings in a dedicated room is to make the fire-extinguishing system equipment to avoid being the impact of adverse weather conditions or subjected to other mechanical damage. while allowing staff to manage and maintain.)

Particle size droplets of water mist fire-fighting capability and the relationship
A water mist extinguishing function is more complex, it is with the type of fuel, fuel quantity and the combustion speed and mist particle size and so on. Particle size droplets and mist extinguishing the relationship between the ability is quite complex, the general said,water power sprayer Ⅰ and Ⅱ mist liquid oil tanks used to fight the fire better, and do not stir the oil tanks liquid level.
2, under normal circumstances, it is difficult class Ⅰ Class A combustible mist off because class Ⅰ mist can not penetrate carbonized layer soaked burning material. However, if the spray rate is high, the surface combustion, or the closure has a greater degree of reduction in the case of oxygen, A class of fire was put out can Ⅰ type mist. This phenomenon shows that drop size distribution can not be determined only by water mist fire exterminate a given capacity. Can the fire was extinguished, depending on characteristics such as fuel, confined space effect, mist intensity and mist velocity (momentum) and other factors.
3, for a given protected object, the size of the droplet mist ability and suitability determination is not the sole basis, it also has a relationship with the flame garden sprayer backpack spray direction, mist intensity and speed of the jet

Technical services should be close to the needs of farmers
Discussions, the participants believe that the conditions of agricultural mechanization good place, not necessarily represent the local agricultural mechanization to achieve good results. Agricultural mechanization in the expanding cultivation areas, an agricultural area of at least two members working acres, as many as 10 acres, directly affects the level of intensive agricultural production, agricultural hand if no professional training,home garden sprayer it is difficult to farm machinery and agronomic techniques for effective integration, affecting mechanized advantages into full play.
In this regard, some students suggested that in promoting the integration of agricultural agronomic work to "software and hardware" grasping, more attention to the training of farm hands. To strengthen the practical teaching, choosing to develop better agricultural cooperatives, agricultural service organizations, etc., to establish training bases, extensive integration of agricultural agronomic training; intensify support, especially in areas with high levels of agricultural operations in rural practical talents training, "Sunshine Project" and other projects, would like to moderately sloping agricultural hand training; strengthen promotion, improper agricultural operations to the adverse effects of widely known to do, and constantly improve farmers, farm hands and other related personnel level of awareness.
The significance of anti-rule has been widely recognized by the Secretary of Agriculture grassroots, but many Secretaries concerned has undertaken against the ruling system is still relatively low level of work, "points to the farmers drugs, the farmers themselves to play a dozen back a farm sprayer, which with a real sense of the anti-rule there is a great distance, can not meet the needs of farmers. "
Against the ruling system require a higher level of specialization is working, but a lot of grass-roots plant protection station is currently in a "name only" state, such as Xinjiang Emin County Farm Bureau's only one plant protection staff also has over 50 years of age, the work force is weak . Discussion, we think, should actively encourage and guide the professional management services organizations in the specialized anti-rule, and its focus on helping to reduce investment, increase revenue on. Participants felt that the state should give more attention and support, as soon as possible the introduction of "crop pests specialized anti-rule management approach" supporting measures, machinery purchase, personnel training and other support efforts to increase and guide special anti-organized development.
After the end of the five-day training, a student from Gansu excitedly said: "In the past few days to participate in training, not only made many friends, but also learned a variety of food knowledge, which for guidance for local agriculture development is very useful. "

The use of agricultural sprayer
Hand Sprayer
1 To properly install the sprayer components. Check all connections for leaks, use water spray test before installation and then install agents.
(2) when the first official use of additional agents, add water, the liquid's surface can not exceed the safe water line. Pulling the joystick before spraying more than 10 times, so that the barrel pressure up to operating pressure. Not use excessive force when pulling the joystick to avoid the gas chamber explosion.
3. The initial loading of liquid, because the gas chamber and spray bar contains water, the spray initial 2 to 3 minutes, the injected liquid concentration is low, it should pay attention to fill plastic sprayer spray to avoid affecting the pest control effect.
4 After work should be poured barrel residual liquid, washed with water and pour dry, while checking the gas chamber without water, if water, to remove the water connector release water.
5 If you do not use the spray near term, the main components should be clean, dry bottles in a cool dry place. If the long-term need, all metal parts have to be buttered, to prevent rust.
Knapsack Sprayer Duster
1. Equipment operation should be preceded by gasoline engine oil system checks the operation method and circuit system, and then start to ensure that gasoline is working properly.
2 test with water before adding the liquid hand pump sprayers spray once, check for any leaks everywhere. Do not overfill plus liquid, the liquid must be clean.
3 dusting operation the whole machine should be in powder state. Shut the door and powder pink, powder should be dry and free of debris.
4 Use the process time not too long, should be 3 to 4 people form a group alternate job, you must wear a mask to avoid wind operations, prohibit the operator in front of the nozzle to spray 8-shaped oscillating manner.

Water mist extinguishing mechanism and application
Water mist system key to success is to increase the surface area per unit volume of water particles. After the fine particles of water, even if the same volume of water, but also can increase the total surface area. And the surface area increases, the more easily heat absorption, cooling the combustion reaction. Absorbing heat of vaporization of water particles easily, the volume increased by about 1700 times. Because the generation of steam, both dilute the concentration of oxygen near the flame, choking the combustion reaction, and effective control of the heat radiation. It is believed that water mist is mainly through high-efficiency cooling and the dual role of hypoxia asphyxia.
Water mist particle diameter size distribution and fire-fighting capability of the relationship is a complex issue. In general, the first one and two water mist extinguishing liquid fuel tanks for fire better, and does not stir the liquid pool. Typically, with the first stage trigger sprayer spray extinguishing Class A combustible material is difficult, it may be that the water mist can not penetrate and wet combustion products carbon layer. However, because the fine mist ejection speed is high, the burning surface or in a closed space, is conducive to reduction of oxygen in the case, or can extinguish Class A combustible material. This shows that, for a given combustion, the particle diameter of water mist fire-fighting capability is not the only factor in the decision. Fire Extinguishing system but also with respect to water mist spraying flame direction, velocity and water density, which are closely related.
Tests showed that a single low-pressure system to produce a greater flow of water particles, in the fight against the fire class A deep, showing good results. This is due to its relatively large flow (single-flow high-pressure system, 3 to 4 times), resulting in a wet surface effect, but reduced the system by blocking the fire extinguishing capabilities. The single-stream pressure fire-extinguishing system is exactly the opposite effect, due to the smaller diameter of the water particles to improve the fight against fire by blocking the ability of the weakened extinguish Class A fires deep effect. Test showed a large space by the blocking of the fire, the fire place when the oxygen concentration to 18%, the flame can be extinguished.
Water mist system with an alkyl halide or other gas extinguishing systems, fire extinguishing time is much longer, the former is about 100-200 seconds, which is around 10-20 seconds. In addition, the size of the enclosed space open water mist effect is small, in an open space, water mist system than the gas fire extinguishing system has obvious advantages.
The size of the fire, water mist fire extinguishing system effects also affect the fierce fires are burning slow burning fire easily extinguished. This is because it quickly consumes the oxygen, and is accompanied by the generation of large amounts of steam and turbulence. hand held sprayer Spray water mist system, while the temperature of the fire a sharp decline, which helps reduce the heat caused by artificial fire and property damage.
About mist electrical insulation, a foreign company has used Securipex Fire-Scope 2000 water mist system been tested, injected into the system with electric motors, generators and power strips inside a closed room, the equipment inside voltage is 220 ~ 440V. The results show that in the release process, the resistance readings decreased significantly, but as usual, the device is operating normally. In the general case, as the device becomes dry, the resistance value will be restored to normal. Can water mist system for electrical equipment, the key lies in the mist particle size. Certain types of water mist systems for electrical equipment should be certified by the relevant departments.
I think that the water mist system can be used to protect valuable factory production equipment, high-rise building immersed power transformers within the chamber, owned diesel generator room and storage room and fuel, gas boiler room. High-pressure water mist system and Shuangliu media can be used for important high-rise building in the high and low voltage power distribution room, it is important electronic communications equipment room, power plant control room, gas turbines and other places.

Pesticide spraying anti Mistakes
Front of the body, "the" word swinging agricultural sprayers. Disadvantage is that the front spraying, people in the drug environment sprayed forward, likely to cause pesticide poisoning, in addition, herbicide spraying closed easily when sprayed uneven Tacai will destroy the membrane artificially reduce the control effect. Sprayer should be changed right in front of "the" word of lateral swing "the" word swing.
Motorized sprayer and hand sprayer to spray herbicides should be taken when spraying sideways parallel to the way forward.
Large droplet spray. This approach would spray uneven, particularly those affecting tag insecticide control effect. Large liquid droplet spray is also easy to cause the loss of plants low, the waste is more serious.
Direct "target" crops. Direct spray sprayer can be used generally, and motorized sprayer to mist type, direct spray will greatly reduce the work efficiency, can not be fully motorized portable sprayers good atomization characteristics of high efficiency. Sprayer job the right way should be 20 cm above the crop, spray drift downwind implementation.
Sprayed liquid dripping from the extent of the blade. According to scientific determination of liquid drops on the leaves, the liquid precipitation was only 50% of a large amount of precipitation can not maximize the efficacy and cause a lot of pesticide waste. It should be evenly sprayed, try not to have liquid dripping.

Promotion of new agricultural technologies to boost agricultural production
A "change" to see farming: In conventional mining, or cattle farming labor day, but 0.3-1 acres, while also spending a lot of labor to complete raking, and other follow-up work due to broken; Today, effort, labor, money micro-farming Machine gradually became the protagonist of autumn plowing, plowing harrow a successful, very convenient. Since 2005, Sichuan Tongjiang County Area recruit new types of marketing Tiller 98, the annual plowing an area of 7200 acres.
Two "change" Look field management: the past, the main use of manual weeding or hand sprayer plant protection, time-consuming; recent recruit Tongjiang County, Sichuan Province Area of motorized sprayer has a significant increase in the amount of the agreement mechanical plant protection area of 3260 mu / years.
Three "change" look harvesting threshing: In the past, either rice or wheat harvest are cut ear and then resort to the use of artificial field awkward, very few farmers with tractors Tractors grind field; vigorously promoted in recent years, the entire chip area motorized thresher, motorized threshing machine has basically reached households Ping units, semi-mechanized harvesting rice and wheat threshing rate of about 70%.
Four "change" look crop stubble treatment: the past,sprayer even after wheat and rice harvest artificial mowing, and dried before ignition burned, time-consuming and polluting the environment; Now, after harvesting crops or directly Tiller chopped straw shredder will also field buried, neither pollute the environment and increased soil organic matter, and fertilize the soil fertility.
Five "to" look on the utilization of fallow fields: In recent years, as national agricultural support policies in place to help farmers, but also farm help, the majority of farmers enthusiasm greatly improved. Now, rice uncollected before, we put on the early dry paddy field, to be harvested after the busy planting canola, spot wheat, vegetables. If in the past, many farmers harvest rice on the land would be reluctant to busy, or direct water to make winter paddy field, or simply turn a blind eye abandoned.
Six "change" to see the rural industrial structure adjustment: promotion of new farm machinery to promote a large number of Tongjiang County, Sichuan Province recruit Area agriculture, pressure sprayer forestry, animal husbandry, and the healthy development of industries and the transfer of rural surplus labor force of new outing more than 1,200 workers, large agricultural machinery, grain, vegetables, large, pig large number of relatively large increase.

Tobacco scientific use of pesticides
Pesticides on the development of human civilization, agriculture has played an important role, especially in controlling risk, when the outbreak of pests and diseases, pesticides also show an irreplaceable role. However, in the course of pesticides on the air, soil and water will cause a certain degree of pollution, which requires scientific use of pesticides, with the least amount of the most effective pest control for maximum economic, social, ecological and environmental benefits.
In view of the status of tobacco production, the State Tobacco Monopoly Bureau, Science and Technology Education proposed the development of "pollution-free tobacco" new ideas, backpack weed sprayers relying on science and technology can make use of the use of pesticides near or at the effects of pollution. Despite the development of biological pesticides now in full swing, but it is widely used in the tobacco need to take time.
LD50 (ld50)
LD50 is the result of a biological experiment death of the individual populations of 50% of the dose. According to China Pesticide Toxicology grading standards, rat oral: ld50 <5mg/kg are highly toxic pesticides, such as "aldicarb" original drug ld50 of 1.0mg / kg; ld50 is 5 ~ 50mg/kg is a highly toxic pesticides such as "omethoate" original drug ld50 is 47mg/kg; ld50 of 50 ~ 500mg/kg belong moderately toxic pesticides, such as "fenvalerate" original drug ld50 is 451mg/kg; ld50> 500mg/kg belong toxicity pesticides, such as "In addition to bud through" the original drug ld50 of 1250mg / kg; ld50> 2000mg/kg are practically non toxic pesticides, such as pest control tobacco warehouse "insurable special" original drug ld50 is 34600mg/kg. ld50 reflect pesticides on the environment or the degree of harm to humans and animals by improving the formulation processing technology, can achieve low toxicity of highly toxic pesticides, toxic pesticide poisoning micro. Such as "decis" the active ingredient is "deltamethrin", "deltamethrin" original drug ld50 is 138.7mg/kg, belonging to moderately toxic, processed into 2.5% EC ("decis") After, ld50 is 535mg/kg, belonging to low toxicity pesticides. "Aldicarb" original drug is very poisonous, but commonly used to control aphids Tobacco 15% "iron aldicarb" granules (ld50 is 10.6mg/kg) is highly toxic.
Half-life (dt1 / 2)
Pesticide degradation half-life is a measure of the degree of difficulty of the targets. It reflects the pesticide sustained effect on pest control and pesticide residues levels. agricultural sprayer Long half-life of the pesticide persistence length to pests and diseases, can in a very long time to maintain the role of harmful organisms performance, but it is also the source of pesticide residue formation. dt1 / 2 <3 months of easily degradable pesticides; dt1 / 2 of 3 to 12 months for the middle of pesticide residues; dt1 / 2> 12 months for the long pesticide residues. Early use of arsenic, lead and mercury preparations half-life of 10 to 30 years; half-life of organochlorine pesticides in 2 to 4 years, the half-life of organophosphorus pesticides are generally a few weeks to a few months ("phoxim" The half-life in soil is 34d), carbamate pesticides generally only a half-life of ~ 4 weeks ("aldicarb" In the half-life of fresh tobacco 14.4d), pyrethroids, sprouting products and herbicides half-life of a few days ("deltamethrin" In the half-life of fresh tobacco 2.1 ~ 4.2d; "In addition to bud through" in the half-life of fresh tobacco 2 ~ 4d; Napropamide in the half-life of fresh tobacco 3 ~ 4d).

China should attach importance to agricultural equipment multifaceted sustainable development
A sustainable agriculture and water-saving irrigation technology and equipment problems. Of water scarcity. Water per year 30 billion m3, drought area of 20 million hm2, the country has 80 million rural drinking water. Therefore, we must find a way out from the water, develop water-saving agriculture. Currently, the promotion of water-saving irrigation technology and equipment has matured, but water-saving irrigation equipment, there are some issues to be resolved. First, China's water-saving irrigation machines and mobile machine nozzle, joint form basically the same, you can choose range of small, bottle plastic sprayer rotating nozzle uneven wear. Wind nozzles, special nozzles to be research and development. Secondly, micro-irrigation technology in the domestic micro sprinklers, drippers, various forms dropper with fewer species. System complete with control equipment, filters, fertilizer, injectors, and other key technology node blockage need to overcome. Third, water-saving devices, "three" low level, but also to further improve standards.
Two sustainable agriculture and land conservation technology and equipment problems. Of land conservation imminent. According to statistics, currently expanding desertification area has reached 1,533,000 square kilometers, accounting for 15.9% of the land area. Erosion surface increase, 39% of the country's total area; land quality declining arable land 59% of phosphorus deficiency, 23% potassium, 14% lack both phosphorus and potassium, 30% nitrogen deficiency province's arable land, China low-yielding fields representing about 70% of arable land; land resources severely damaged due to various human factors, derelict land total 200 million acres; national grassland each year 30 million mu to 4000 mu degradation, desertification grassland (50%); 70 % arid and semi-arid grassland. Nearly 10 years, the national forest area decreased by 23? 1%, the agricultural ecological environment deterioration, reduced water storage capacity. Land pollution is worsening. From industrial "three wastes" pollution, contaminated land 6,700,000 hm2; affected by acid rain harm agriculture 2,660,000 hm2; national industrial solid waste and municipal solid waste a total area of 5.36 million hm2, which accounted for farmland 40000 hm2. As well as from the pollution of agriculture itself, mainly excessive application of pesticides, resulting in changes in soil properties, soil fertility decline and so on.
To this end, research and development of grass and trees terracing of special machinery and equipment development project is imminent. Promotion and development of new ultra-low-volume knapsack power sprayer spraying (powder) device, so that the liquid droplet diameter down to 15μm ~ 75μm, reduce pesticide use, improve the efficacy and control effect; development of new agricultural film recycling machinery and equipment, prevention of pollution of agricultural plastic film .
Three dimensional cultivation of sustainable agriculture and technical equipment problems. Stereoscopic three-dimensional cultivation of agricultural cultivation, including three-dimensional cultivation, livestock integration, planting combination, courtyard economy mode. Machinery and equipment in this regard very little mechanization intercropping is a major problem, this is not caused by power machine and supporting tools; farming raise land farming techniques and equipment developed much, much less be able to use; courtyard economy is on the rise among , there is no typical mechanical equipment developed. Stereoscopic both sustainable agriculture cultivation technology and equipment needed for development, but also the "three rural" market need to develop products.

Knapsack sprayer application techniques
Knapsack sprayer, is a lightweight, flexible, high-efficiency plant protection machinery. You can complete the dusting, spraying (including ultra-low volume spraying), spraying granular fertilizer, spraying pesticide granules, items such as health and epidemic prevention work. Mainly suitable for large-scale agriculture, forestry crop insect pest control work. The aircraft belonging to low-volume spraying machinery, the use of technology than conventional large-capacity sprayer spray demanding. Its control effect, efficiency, operating costs and so on and use the hand to operate the machine. Currently, the country sprayer social ownership has more than 400 million units, but a lot due to improper use, failure to give full play the advantages of proper sprayer. Farmers still use manual spray application methods, accustomed to high-capacity targeted sprays, mistakenly believe that foliar spray to start flowing in order to achieve good control effect, so that not only could easily lead to re-spray, leak spray, liquid huge loss of effective deposition was reduced, the control effect is poor, and to achieve their spray rate and reduced efficiency, a serious waste of pesticides, increase cost. Therefore, we must fully understand and correctly grasp the scientific application techniques, to improve efficiency, reduce labor intensity at the same time to get better control effect.
Preparation before operation:
1, do a good job machine maintenance, repair, maintain its technical condition good; prepare enough fuel. The machine uses a single-cylinder two-stroke gasoline engine, must be added to a mixture of oil and gasoline oil, gasoline with 70, with the 10th summer motor oil, No. 6 oil in winter, the ratio used by 1:22.
2, in accordance with the spraying, dusting, such as different jobs require assembly machines; Check all parts are installed correctly and firmly.
3, according to the different kinds of pests of different crops were determined using pesticides, Mushi dosing and dilution; Plant Protection Station, according to the local release of pest information, identify specific pesticide appropriate period.
4, before spraying begins, measure the knapsack sprayer at rated speed traffic. In the medicine cabinet in the amount of water added to reach the rated speed for horizontal spray, spray finished measured the time required to calculate the rated flow (kg / min).
5, machine hand job walking speed is directly related to the amount of pesticide per unit area, must be based on the amount of acres sprayed requirements and effective spray pattern width, take appropriate walking speed, in order to ensure consistent application rates. General machine hand walking speed of 1 m / s or so, which is equivalent to normal walking speed. The aircraft's horizontal range above 9 m, according to various different crops and crop growth period, to determine the effective spray width. For example, the control of cotton pests, can be pre-set at 4 to 6 lines (3 to 5.4 meters), the latter may be set for 2 to 4 lines (1.5 to 3 meters). In order to ensure uniform spraying while improving efficiency, large spray rate may slow walking speed, sprayer rate hour walking speed can be accelerated.

Weeds cause of relapse and Countermeasures
In the actual process of chemical weed control, there is a part of the plots is not completely dead grass, weeds recurrence. If the area is small, less weed, it can be considered a normal phenomenon. Because the weeding process will inevitably occur leak spray, light spray of the phenomenon, while in the weed communities will inevitably be part of the emergence of resistant weeds, chemical weed control is not 100 percent results. But if there is a large area of recurrence, they should pay attention to it. After years of observation the author concluded that the presence of weeds recurrence following reasons:
1, herbicides too quick result, only wheat as an example: if one is leaf tag azole grass herbicide, weed fast when weed is only slightly above the ground to kill the majority of blades, and miscellaneous dead grass and roots growing point, easy to relapse.
2, herbicide solution concentration is too high, also caused rapid killing blades, undead roots phenomenon.
3, too little water spraying, back pack sprayers uneven. Based on the investigation, at the same herbicide doses acres sprayed a bucket of water (about 15 kg), the recurrence rate than acres sprayed three buckets of water 20% higher.
Responses: 1, quick and slow-acting herbicide solution reasonable ratio problem. Such as: Tribenuron + Fluoroglycofen ether formulations, if Fluoroglycofen ether the amount of acres more than 20 ml (10% EC), the speed of 3-5 days dead grass, weeds on tribenuron absorption and conduction decline, weeds easy to relapse.
Therefore, we can control the dead grass in 7-10 days time, thus reducing the recurrence of weeds, proved tribenuron + Fluoroglycofen ether formulations to 10% tribenuron 12-15 g +10% Fluoroglycofen ether 8 ml is appropriate.
2, improve the quality of spraying, and strive to have, thoroughly. Spraying directly affects the quality of the herbicidal effect, require the use of manual manual sprayer spraying, mu liquid volume of not less than 30 kg, to ensure that no re-spray, spray does not leak.

How to improve the utilization of pesticides
Want to improve the utilization of pesticides, it is necessary to improve the quality of the manual spraying machine, spraying parts single change the status quo, to promote the upgrading of manual sprayers
Spray atomization quality is the determining factor, directly affect the deposition of pesticide on crops distribution. Droplet distribution density is related to the control effect is an important factor. The same amount of liquid, if the droplet size by half, and the resulting 8-fold increase the number of droplets. Led the establishment of the National Agricultural Center in Shandong Wish Plant Protection Machinery Co., development and production of the "Guardian" card WS-16 Type Sprayer, won the national key new product certificate and four patents, and has been the first to get "3C" certification, becoming the ideal replacement of manual sprayers varieties.
The implementation of low volume spraying technology to reduce the amount of liquid present Mushi
Crop leaf surface can be attached pesticide droplets is limited, when spray volume exceeds a certain limit, the leaves on the tiny droplets will agglomerate into large droplets and rolled, the loss, but to make the blade attached to the drastically reduced the amount of pesticides . Spray volume in developed countries are generally controlled at 100 per hectare - 300 l range, less spray volume per unit area of 1/3, and thus the loss was minimal, pesticide utilization is higher.
Application techniques to carry out extensive training, so that farmers master the scientific method of application
Adopted a hydraulic sprayer atomization, high pressure liquid through a small orifice in the rear, to go through more than 30 cm distance to be able to completely atomized, so when spraying pesticides, must maintain the distance between the nozzle and the crop
30 cm above the surface to avoid the spray nozzle close to the crop. When using spray nozzle cone fog job, should be changed about the direction of advancement of bilateral "Z" shaped cross spray habit while taking downwind side "Z" shaped spray application personnel to ensure that the area where no drugs area. At the same time, should be gradually replaced with a fan nozzle cone fog mist nozzles, spray take unilateral parallel advance method to improve the uniformity of the distribution of pesticides. Sprayer takes the pneumatic atomization, the farther away from the nozzle, droplet finer spray rate in the general level of more than 8 meters. Spraying pesticides, to take full advantage of its effective spray rate, spray taking drift superposition method to improve the efficiency and control efficiency, avoid targeted household sprayer spray. Operations, shall determine the nozzle pointing direction (spit), machine hand to the routes (strike) and field operations in the order (starting from) principle, so spit as consistent as possible with the wind, and wind machine hand to be Vertical, if skewed, machine hand can be adapted to their body slightly oblique, not wind operations. From downwind start operations to ensure work area is free of pesticides zone. According to the control object and crop pests and diseases at different growth stages as well as parts of flexibility nozzle height and angle. Currently, the majority of farmers commonly used around the forward direction intersecting spray method, spray width is reduced, the formation of turbulence, resulting droplet distribution is uneven, but the entire operating environment filled with pesticides are very vulnerable to pesticide poisoning people, should be changed as soon as possible and avoid.

Spray volume in developed countries are generally controlled at 100 per hectare - 300 l range, less spray volume per unit area of 1/3, and thus the loss was minimal, pesticide utilization is higher.
Application techniques to carry out extensive training, so that farmers master the scientific method of application
Adopted a hydraulic sprayer atomization, high pressure liquid through a small orifice in the rear, to go through more than 30 cm distance to be able to completely atomized, so when spraying pesticides, must maintain the distance between the nozzle and the crop
30 cm above the surface to avoid the spray nozzle close to the crop. When using spray nozzle cone fog job, should be changed about the direction of advancement of bilateral "Z" shaped cross spray habit while taking downwind side "Z" shaped spray application personnel to ensure that the area where no drugs area. At the same time, should be gradually replaced with a fan nozzle cone fog mist nozzles, spray take unilateral parallel advance method to improve the uniformity of the distribution of pesticides. Sprayer takes the pneumatic atomization, the farther away from the nozzle, droplet finer spray rate in the general level of more than 8 meters. Spraying pesticides, to take full advantage of its effective spray rate, spray taking drift superposition method to improve the efficiency and control efficiency, avoid targeted household sprayer spray. Operations, shall determine the nozzle pointing direction (spit), machine hand to the routes (strike) and field operations in the order (starting from) principle, so spit as consistent as possible with the wind, and wind machine hand to be Vertical, if skewed, machine hand can be adapted to their body slightly oblique, not wind operations. From downwind start operations to ensure work area is free of pesticides zone. According to the control object and crop pests and diseases at different growth stages as well as parts of flexibility nozzle height and angle. Currently, the majority of farmers commonly used around the forward direction intersecting spray method, spray width is reduced, the formation of turbulence, resulting droplet distribution is uneven, but the entire operating environment filled with pesticides are very vulnerable to pesticide poisoning people, should be changed as soon as possible and avoid.

Spraying pesticides job the right way
Significantly increased over recent years, crop pests, pesticide use increased, many farmers in field operations has formed a fixed manner. But from a scientific point of view, farm sprayer pesticides, there are still some errors:
First, the front of the body, "the" word swinging spray. Disadvantage is that the front spraying, people in the drug environment sprayed forward, likely to cause pesticide poisoning. Further, when spraying herbicide closed, easy uniform spray, artificial membrane damage after treading to reduce the control effect. Sprayer should be changed right in front of "the" word of swing sideways "s" word swing. Motorized spraying and spraying herbicides should be taken parallel advance spray.
Second, the large droplet spray. Make spray uneven, particularly those affecting tag insecticide control effect. Large liquid droplet spray is also easy to cause the loss of plants low, the waste is more serious, you should try to use a good spray atomization performance, the use of spray holes tablets, a small droplet spray evenly.
Third, the jet "target" crops. Direct spray sprayer can be used generally, and motorized sprayer to mist type, direct spray will greatly reduce the work efficiency, can not be fully motorized weed killer sprayer good atomization characteristics of high efficiency. Sprayer job the right way should be 20 cm above the crop, spray drift downwind implementation.
Fourth, the liquid sprayed from dripping on the extent of the blade. According to scientific determination of liquid drops on the leaves, the liquid precipitation was only 50% of the maximum amount of precipitation can not maximize the efficacy and caused a lot of pesticide waste. It should be evenly sprayed, try not to have liquid dripping.

Anti-pest sprayer usually ground maintenance more convenient emergency
Every spring is a variety of crop pests and diseases and prevention peak, also spray application equipment such as periods of high frequency of use. pressure sprayers its structure is simple, easy to use, inexpensive, is widely used in many rural farmers, an important plant protection equipment. At a time when wheat, spring oilseed rape pest control supplies and equipment preparation stage, but some friends of farmers usually focus only on equipment use, pay attention to maintenance, to use the time often confused, resulting in the use of the actual operation generated a lot of inconvenience. Now use the sprayer maintenance and troubleshooting methods outlined below:
First, the use of maintenance
1, using the sprayer should be checked for leaks at the connections, first install water spray test and then install agents for spray.
2, add the liquid, the liquid can not exceed safe water line. Rocker panels before spraying move more than 10 times, so that the barrel pressure up to operating pressure. Note plates move joystick can not be too hard to avoid the gas chamber explosion.
3, the fruit tree sprayers job is completed, should be promptly poured barrel residual liquid, then rinse upside down to dry; also check the gas chamber without water, if water, remove the water outlet connector release.
4, the short term is no longer used, should the main components of clean, dry bottles in a cool dry place; when unused for long periods, pay attention to the various metal parts coated with grease to prevent rust.

Agricultural Equipments Cleaning Method
Mist Sprayer, manual sprayer Agricultural Equipments in other small spray finished drug immediately after cleaning, especially the use of highly toxic pesticides and a variety of herbicides, the equipment should be thoroughly cleaned barrel, the barrel to prevent the next use of residual drugs on crop produce toxic.
Generally, fungicides, insecticides used repeatedly washed with water after drug barrels, and then inverted to dry, the individual in the use of toxic pesticides available after repeated cleaning agents mud bucket, and then inverted to dry. The use of herbicides, should be based on characteristics of targeted cleaning agents.
First, wash with water. Tribenuron, efficient fluoropyrazole A Wo Ling, quinclorac, bentazone and other drugs after spraying, immediately wash with water barrels and various parts of the drug several times, and then the farm sprayer filled with water soak 2 to 24 hours , and then washed 2 to 3 times.
Second is to use mud cleaning. For paraquat, glyphosate case of loss of activity of the soil that is passive, and can be used in medicine after spraying mud wash a few times, then rinse with water.
Third, scrubbing with ferrous sulfate. 2,4 - butylate and other drugs more difficult to clean after application of 0.5% ferrous sulfate solution required scrubbing equipment, and then tested for safety, confirmed harmless before re-use.

Flowers and lawn sprayer control and use of the advantages
Ultra low volume sprayer in the fight against flowers, lawns and crop pests and diseases when compared with conventional sprayers with fast, efficient, lightweight, cost savings and other advantages. Specific performance is less water
Ultra low volume sprayer using a pesticide liquid, or simply through the low-fold dilution, and thus it does not need a lot of water, less medication.
About 100 grams per acre spraying liquid, rather than tens of kilograms, or even hundreds of kilograms. Therefore, when in use can greatly reduce labor intensity, saving labor, droplet evenly distributed.
Ultra low volume than the liquid sprayer spraying directly on the plant, but by virtue of the wind to a diameter of only tens of microns dispersed droplet drift, and then around the plant "micro air" under the action of droplets evenly distributed in the plant leaves and whole plant of positive and negative side. In this way, than adding a lot of water to dilute the medicine after the killing of pests higher rates have been particularly resistant to certain pests, the better. Killing function due to pesticides than the liquid diluted with water several times higher than even a few times.
Easy to use: handheld ultra low volume weed sprayer spraying timing remain at the head of about 1 m above the plant height. Because these spray nozzle eliminating the liquid, the liquid in the bottle itself when put out. Therefore, when the motor is not turned on before the vials should be at the bottom, head at the top. When spraying, you should start the motor, then change the bottle and head position so that the top of the bottle, the bottle down, bottle perpendicular to the ground, the liquid that is their own outflow.
When spraying, under the direction of the wind from the start, to come and go walking routes should be separated by a certain distance, is the spray rate. The size of the spray rate should be based on the size of the wind speed flexibility. Wind hours, spray rate should also be smaller, and vice versa should be bigger, generally 3 to 3.5 meters is appropriate. Spraying time preferably in the morning, afternoon or cloudy, avoid sun exposure. Ultra low volume spraying is best to use the suction agents, fumigants or stomach poison. Dosage generally about 50 grams per acre. For adequate water, can be "equal laws."

How to improve the wear life wear elbow
Wear elbow more than the straight tube wear, rational design to reduce wear and tear on the structure bends have a significant effect. Here are some wear elbow structures.
(A) long radius bends. Pneumatic Conveying originally used long radius elbow. But then bending experiments and practical experience shows that this structure wear serious, life is short, therefore,bottle plastic sprayer does not recommend the use of this structure. In order to extend its working life, the design uses the structure shown in Figure 10. The structure consists of a wide set of one pipe elbows, the gap between the two pipe filled with cement mortar. Article from: Jianhu Yuanda
(2) increasing the use of part of the circulation pipe cross-section, so that the outer part of the material flow tube deterioration intentional elbow at the stagnation in the material, so that the material particles collide with each other, to prevent wear and tear on the pipe wall. Elbow can be designed into a more rational structure.
(3) short radius elbows. With T-tube similar to a pipe that is introduced in the 1980s foreign short-radius (R / D of about 2 to 3) elbow. The elbow in the corner there is also a material build-intensive areas but does not exist "cavity." But it does not appear as one end of the barrier inside the T-elbow wall "feed back" situation.manual sprayer According to some test data indicated that short radius elbow long radius elbow wear resistance than good, more than one end of the T-tube somewhat less unreasonable.
