To de-worming medication flowers counterpart
In actual production , flowers , like other crops are also vulnerable to a variety of pest infestation . Flowers in the fight against pests , such as insects according to different mouthparts symptomatic spraying , to improve the control effect will be of great benefit.
Chewing mouthparts of insects , such as yellow slug , the day suddenly caterpillars, beetle daisy , leaf miner , grubs , black cutworm , mole crickets, flies and other species , damage flowers , fruit tree sprayer the principal cause floral tissue mechanical damage. Leaf feeding pests such as flowers , leaves often cause defects , and even leaves eaten ; eats flowers, stems , fruits and seeds of pest infestation drill into its internal organization , often caused by holes in the surface , the formation of worms in the internal tract ( such as chrysanthemum beetles, bees , etc. rose stems ) ; lurking in leaf epidermal between feeding pests leaves left in the serpentine road insects , often the leaves wither , caducous ; feeding after sowing seed , seedling roots , corms , bulbs and tubers and other flowers underground pests , often caused Deficiency or seedling lodging, and even whole dead . Flowers in the fight against chewing insects , the stomach may be the preferred toxic pesticides , the most commonly used agents have trichlorfon , sodium fluoride , etc. The absorption of chemical agents such as monocrotophos, omethoate and other chewing mouthparts and has a good killing effect .
For sucking mouthparts , which feeding method is to use the mouth needle into flower leaves, flowers, shoots , stems and other tissues , drawing juice. Flower shape suffer no mechanical damage , only parts of the formation in the victim faded spots, or cause tissue malformations ( such as wrinkled leaves , leaf , galls , etc. ) , common pests sucking mouthparts scale insects, aphids, thrips , whiteflies , mites and other insects. In the fight against sucking mouthparts damage , the drug of choice is a systemic insecticide , such as omethoate , monocrotophos , carbofuran and so on.manual sprayer Contact toxicity of insecticides such as malathion , phoxim , cypermethrin , deltamethrin and other pests on flowers and has a good control effect. It should be noted that the prevention of gastric toxicity of pesticides on flower sucking mouthparts pests largely ineffective .

How to use glyphosate vegetable
Some farmers ask: " where you can use in vegetable Herbicide Glyphosate do ? " Yes, but pay special attention to the use of technology , otherwise easily cause injury to the vegetables !
Glyphosate , also known as Roundup , glyphosate , farmers' music , etc., is an organic phosphorus herbicide active ingredient glyphosate on weeds within the absorption spectrum Destuctive type herbicidal action for foliar treatment , deep- rooted perennial weeds can be killed underground parts, but you will soon encounter soil failure , for failure to weed unearthed invalid .
Use of glyphosate , the general and other weeds out of Qi , 4 to 6 leaf stage , with 10 % water 0.5 to 1 kg per acre , plus diesel oil 100 ml , add water about 20 to 30 kg , evenly spray weed stems .
Glyphosate herbicide for vegetable , vegetable garden is no vegetables should only be used when per acre with 10 % water 0.5 to 1 kg, the eradication crabgrass, annual bluegrass , Amaranthus spinosus , wild peas and other weeds . With 10% aqueous 1 to 1.5 kg , elimination nutsedge , plantain , small canadensis year, Peng and other weeds . With 10% aqueous 2 to 2.5 kg , elimination Imperata , reeds, Ploughshares grass, half bottle , dog shoots root , Pinellia and other weeds . Both on the water 60 to 75 kg, and the whole field garden sprayers spray.
On weeds by foliar application , the non- liquid contact with the vegetables and other crops , to prevent injury.
Chives to herbicides should be the day after the harvest leeks ( can not drag day medication ) , with 41% Roundup agent, based on annual weeds plots, with liquid 0.2 liters . Perennial weeds in plots with aqueous 0.3 liters of water 30 kg , the whole field spraying liquid.
Lily to herbicides , it would be flowering lily , washed with 10% aqueous 1 to 2 kg , 50 kg of water , spraying the whole field , to eradicate Imperata , Paspalum distichum , dog root buds , yellow ( purple ) Cyperus and other weeds . On lily secure.
When spraying , use 0.8 mm diameter nozzle than the commonly used 1.0 mm diameter nozzle effect. Pharmacy effective after contact with stems and leaves , knapsack sprayer spraying should be uniform , so that weeds adhesion agents.
With a lower hardness of water preparation of liquid , used to be repeated cleaning spray to avoid future injury caused by use of other crops . Not with MCPA , Gramoxone and other fast-acting herbicides mixed use . Such as glyphosate adding 0.1% detergent, or the amount added to 30 g of diesel per acre , can enhance the efficacy .

The use of herbicides for weed control lawn a few points
1 , learn to distinguish between several types of weeds, and generally does not commit an error in principle .
2 , the distinction between the young plateau of lawn grass , which should be used on turf herbicide .
3 , the choice of herbicide to be exact right path . Lawn weeds and weeds within the field is not the same . Farmers' fields in the weeds , because perennial farming, rarely perennial weed . Weed in the field of the main places that gutter , street , canal head , farm , rather than crop land , this must be fully recognized. The lawn, nursery , the lack of deep plowing conditions , perennial weed often occurs serious . We should recognize , lawn weed weed weed is much more complicated than that .garden sprayers Farmland weed can "fool " and we can not use the lawn , " fool" , at least just contact herbicide lawn or nursery not. But in the first year of the most vicious weeds removed through various methods after the second year was much better .
We are currently used herbicides in controlling weeds are basically annual weeds . Perennial weeds are perennial, deep roots , are generally no longer present within the range of weed herbicide . But you can take special measures individually vicious weeds . But in no case do not exceed the recommended range of herbicides used .
4 , during spraying , when selecting the right herbicide attention after "three " principle. Namely herbicides acres usage, mu against water sprayed area is established , do not arbitrarily increase or decrease , which is crucial. Under normal circumstances, do leaf processing, an acre of lawn requires 25-30 kg of liquid to spray evenly ( general agricultural sprayers two watering ) , such as using Ping wide net , elimination Wo , elimination miscellaneous, music , etc. weeding clover . However, the soil to be closed , then the dosage per unit area determine the circumstances , against the need to increase the amount of water to 50-60 kg acre lawn trigger sprayer spraying liquid to uniform ( usually watering agricultural sprayer 4 ) , otherwise it is not easy to form tight membrane, such as the use or play Ping Yue Jin Baixiu closed weeding to do .
5, the use of herbicides when soil moisture is essential. Good soil moisture to ensure herbicidal effects of drought poorly.

Lime sulfur mixture preparation
Lime sulfur, lime sulfur mixture referred to their method of preparation are as follows :
( A ) fresh and high quality materials, lime sulfur powder 0.5 to 1 kilogram of water 1 to 2 kg 10 kg .
( 2 ) Method calcium polysulfide cooking wok must be born with a large ( tank ) or earthen pot , you can not use copper, aluminum and other containers or corrosive damage. Remove enough water initially said the proportion of part of the water used to dissolve another part lime water into the wok and heat . Fever of open pending quicklime into lime dregs filtered into the pot after pot of water level measurement mark and continue heating the water to boil and slowly thrown into sulfur powder ( or sulfur powder add a little water into a paste before slow slowly pour the boiling milk of lime homogeneous medium ) while stirring constantly . weed sprayer Note firepower should raging fire . In the cooking process continue to make up the boiled by the heat dissipated by the amount of water each time the amount of water is not too large to prevent the impact of sudden cooling liquid mass , and 15 minutes before the ceasefire to stop adding water. Also when you start cooking more 1 /3 of the water is in the middle do not add water conditions continue to cook over high heat for about 60 minutes cloudy yellow liquid from the pot into a clear dark red ( dark brown ) , dark green trash can ceasefire. Cooking time is too short or insufficient firepower of liquid waste into yellow concentration is low. Generally do not exceed the longest brewed for 1.5 hours. Cooked orange liquid cooling remove the supernatant after precipitation of calcium polysulfide liquid that was used Baume hydrometer measurement that is known concentration of this stock solution crossing .
( 3 ) the use and preservation method cooked well, liquid quality is high, the concentrations of up to 30 Baume , but in general should also be up to 20 to 26 degrees Baume . Cooking is the key to the quality of lime and sulfur powder and cooking process firepower to continue to maintain boiling. Quicklime is best to use good quality white lumpy , as with weathered lime must be increased by 30 % of the amount . The use of lime sulfur concentration must be strictly controlled according to temperature changes , otherwise easily cause defoliation , sunburn and so on. Winter garden clearance of 0.7 to 0.8 degrees Baume available in spring available 0.3 to 0.4 degrees Baume . Summer high temperature (30 ℃ above ) , the winter cold (4 ℃ less ) are not suitable for use lime sulfur . If you must use , in the hot season should be controlled at 0.2 Baume degrees or less. plastic sprayer Spraying time should be 10:00 or 15:00 before after drought periods should also be strictly controlled medication. Utensils after use must rinse .

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 , spray uneven. Based on the investigation , at the same herbicide doses acres knapsack sprayer 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 manual sprayer spraying , and strive to have , thoroughly. Spraying directly affects the quality of the herbicidal effect , require the use of manual sprayers spraying , mu liquid volume of not less than 30 kg , to ensure that no re-spray , spray does not leak .

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. "

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.

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.

Plastic applications in the chemical industry
Environment and resources is the world's most compelling topics, scientific and rational use of limited resources is a fundamental protection.
Worldwide due to corrosion of materials, consume a lot of resources, resulting in huge losses to humans, hindering the development of productivity and leads to further deterioration of the global environment. According to some industrial countries, statistics, due to corrosion caused direct losses of GNP (GNP) of 2% to 4%, the most developed of the U.S. up to 4% or more. China every year due to corrosion caused direct economic losses of at least 200 billion yuan.
As an emerging class of plastic material, a relatively excellent chemical inertness and other good overall performance, has been in the field of anti-corrosion has been widely used. Plastic is an interdisciplinary corrosion, corrosion study and master the theory and application of plastic for further promote and expand the field of application of anti-corrosion plastic, save social wealth and resources have a very positive meaning.
1 Definition of plastic corrosion
Corrosion is a substance called environmental effects due to damage and deterioration caused by the phenomenon, the plastic sprayer in the chemical environment, the role of the media, its appearance, and mechanical damage caused performance degradation phenomenon, known as etching or chemical aging of plastic. Chemical aging is a form of plastic aging.
2 types of corrosion plastic
With the kind of plastic, chemical media, and environmental conditions, there may be different forms, varying degrees of chemical aging and erosion. Such as: Appearance (extinction, discoloration, wrinkling) changes, and mechanical properties (optical properties, electrical properties, weight) changes and chemical changes in structure and properties, study and master the plastics chemical aging of the law, can be more scientific and more reasonable used plastic, better use of plastics to solve corrosion problem.
Plastic corrosion basic reason for this is due to the chemical medium to penetrate inside the knapsack sprayer, diffusion to swelling, dissolution medium and the plastic cracking or chemical reaction, leading to a variety of corrosion phenomenon.
Plastic corrosion in general can be divided into: the primary valence bond within the polymer macromolecules damage secondary bonds between macromolecules damage. But usually these two types of composite damage and secondary bonds between macromolecules damage as much.
