Banana fertilizer types and fertilization methods

① fertilizer types . Banana applying fertilizer organic fertilizer and inorganic fertilizer of two categories.

Organic fertilizer. Organic fertilizer is organic fertilizer, including human beings and livestock manure , poultry, animal waste , crop stems and dross , ash , green manure and other organic material of plants and animals , as well as river mud , pond scum , swim alluvial mud , contains a more comprehensive nutrients. After the organic fertilizer can improve the physical properties of the soil , improve soil drainage and ventilation performance increase by microbial decomposition of soil humus and nutrients. Organic fertilizer commonly used as a newly planted banana basal or early spring fertilizer, too cold fat , easily decomposed bran cake can be used as fertilizer or flower bud seedling fertilizer.

Inorganic fertilizer . Mast mostly inorganic chemical fertilizers , elemental content, can be dissolved in water or weak acid inside , easily absorbed and used bananas , fertilizer is high and fast, very easy to use . But some improper use of inorganic fertilizers can cause soil compaction or too acid or alkaline , inorganic fertilizer and organic manure , you can overcome these problems. Bananas used inorganic fertilizers , urea nitrogen fertilizer , ammonium sulfate , ammonium bicarbonate, ammonia , phosphate has superphosphate, calcium magnesium phosphate, phosphate and phosphate powder defluorinated , Potash potassium sulfate, potassium chloride . General fertilizer nitrogen, phosphorus and potassium , the ratio is generally 15:15:15 , Guangzhou Huangpu Canadian foreign plant bananas BB fertilizer production of nitrogen, phosphorus and potassium ratio of 1:0.2:1.33 .

② fertilization methods . There are two types of banana fertilization is rhizosphere fertilization and foliar application . In rhizosphere fertilizer -based, foliar supplement.

Rhizosphere separable liquid fertilizer facilities and dry facilities, and dry Shi was divided applicator , fertilizing and Summer .

Liquid applied . Liquid applied with a water soluble fertilizer diluted will be applied for those easily dissolved instant -use of organic fertilizer bran bread , and livestock etc. to water or human, animal urine, rotten ret only with maturity , dissolved into a paste shall immediately after applying thin soil cover . Liquid manure applied benefit is easy to contact with roots , easily absorbed without causing root , drought Shihai from irrigation effect.

Applicator . Fertilizer applicator is to sprinkle on Qimian , generally after the rainy season , when the soil is also more humid . Mostly dry soil should not dry weather applicator , if dry weather sunny Qimian applicator must first leaching ( irrigation ) wet . Applicator to spread evenly , Shi Bi best shower water once . Applicator has the advantage of saving labor, to expand the absorbing surface , quickly see the fertilizer , but the application of the loss of roots and easily hurt improper waste, especially from May to July banana root easily exposed soil , do you want to control the fertilizer according to the degree .

Fertilizing . Fertilizing in banana plants from 30 to 100 cm digging , hole depth of 15 to 23 cm ( size depending on how much fertilizer may be ) , the fertilizer into the cavity and covered with soil . Yuhan days shall be sufficiently wet to facilitate manure decomposition melt. Benefits of fertilizing is to prevent loss of fertilizer , manure hurt less, but absorption is narrow , fertilizer more slowly and spend more workers . pressure water sprayer Generally too cold for spring fertilizer and manure .

Summer . Summer in the banana plants from 30 to 100 cm 2 1 small arcuate groove , a width of 15 to 25 cm , length 35 to 50 cm, depth of 8 to 15 cm , the fertilizer is applied uniformly in the trench , and soil . Summer In addition to the benefits of fat loss and prevent injuries less fertilizer , the absorbing surface over fertilizing wide, fertilizer than fertilizing fast, but also more flower workers . Generally used for spring fertilizer, manure and too cold autumn fat , not in use from May to July , when the banana plants due to fine roots across the park and out of the ground , ditching easily hurt fine roots .

Banana foliage spray is sprayed to the foliage or fruit surface low according to the degree of liquid fertilizer. The advantage is easily foliar fertilizer leaves or fruit directly . Rapid absorption , replenish nutrition, growth and development to meet the bananas on nutrient needs, especially to the young fruit bud development stage requires a lot of nutrients through the foliage spray can replenish the nutrients it needs , to improve the yield and quality of banana plays an important role . On the other hand , foliar spraying , fruit leaven , fertilizer absorption rate can be as high as 90 %, significantly higher than the rhizosphere fertilization. However, hand pump sprayers there are shortcomings foliage spray , mainly small amount of fertilizer each time , you need to repeatedly administered , flower workers more .

Allowing farmers to master the scientific method of application

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 backpack pressure sprayer 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 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 pressure sprayer 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 .

Flower medication safety technology encyclopedia

As modern urban pollution , people floral ornaments also raised safety drug safety requirements , the following describes ten kinds of flowers medication safety tips :

First, observe rules safe use of pesticides

In floriculture , the prohibition of the use of pesticides are: methamidophos, methyl parathion , back pack sprayers parathion, monocrotophos, ammonium phosphate , BHC , DDT, toxaphene , DBCP , chlordimeform , dibromoethane , nitrofen , aldrin, dieldrin, mercury preparations , arsenic , lead, enemy withered double fluoroacetamide , Gan fluorine, tetramine , sodium fluoroacetate , rat poisoning silicon.

Second, take safety precautions

Application personnel must do the required safety precautions to prevent poisoning. Remaining chemical and pesticide application equipment cleaning fluid , should focus on the safe handling, not free spill. Does not allow re-use empty containers should be properly collected and treated empty containers , empty containers will be marked safe storage ,backpack weed sprayers or centralized treatment.

Discarded and expired pesticides , according to the relevant regulations must not be casually discarded , so as not to produce injury flowers , or to livestock poisoning .

Application Method

Choose the best application time . For closed herbicides , be sure to use before weeds sprout , once weeds grow , increase resistance , weeding poor results. For foliar herbicides should grasp % 26ldquo; except early, in addition to a small % 26rdquo; principle. Weed plant age the greater the resistance will be. In a normal year , about 90% emergence of weeds , weed seedlings organize young , drug resistance is weak , easily killed. In the daily average temperature is above 10 ℃ , use of herbicides recommended dosage limit , will be able to obtain more than 95% of the control effect . Early seedling stage is appropriate poison indigenous ; sensitive to herbicides fast growing period , with particular caution ; seedling hardening of seedlings although some resistance , but most of the weeds have matured , application plays a minor role .

Flexibility dosage. Seedling resistance to herbicides is a certain limit , it can not arbitrarily increase the dosage . In addition, different resistance of different seedlings should be strictly in accordance with product instructions . In general, the dosage of coniferous species can be bigger, broadleaf species dosage should be smaller. The same seedling varieties resistant to certain agents will increase with increasing seedling age , the dosage can be increased accordingly , such as controlling pine, fir nursery weeds can acre with 23.5% of the fruit Seoul EC 50 ml single-use , or 23.5% of the fruit Seoul EC 30 ml plus 50% acetochlor EC l00 ml mix. If used for hardwood species nursery , the dosage should be reduced appropriately. For annual weeds , use the recommended dosage can be. For perennial weed ,hand pump sprayers perennial weeds , you need to appropriately increase the dosage.

Note that when spraying temperature and soil moisture . Temperature directly affects the efficacy of the herbicide . For example MCPA , 2,4% 26mdash; D below 10 ℃ pesticide efficacy poor , 10 ℃ or more pesticide efficacy do. Herbicides fast off spirits , although the ultimate effect of superstar not affected by temperature , but at low temperatures 10% 26mdash; 20 days after the exhibit herbicidal effects . All herbicides should be sprayed on a sunny day when the temperature is high , in order to give full play to efficacy. Whether growing seedlings before soil treatment or foliar spraying , soil moisture are important factors affecting the level of efficacy . Seedlings before spraying, if the surface soil humidity, easy to form a tight seal to kill drug layer of soil and weed seeds germinate unearthed fast, so anti -efficient . Growing application , if the soil is moist ,perfume sprayer vigorous weed growth , which will help the absorption of weeds and weed control agents operate in the body , so the efficacy of play quickly, weeding effect.

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.

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.

Making sprayer

Sprayers many forms, but the core principle of the structure is basically the same. Nebulizer is used to disperse the particles in liquid instruments, electric sprayer in the laboratory and medical work are widely used production process is simple now specifically described as follows: farm sprayer

(1) outlet diameter: jet outlet tube diameter should generally be greater than the inner diameter of the pipette exports doubled appropriate. For example: suction outlet tube diameter 0.5 mm, jet outlet tube diameter is I mm, should be at the head of the pipette Ling gas outlet center distance between the phenomenon can not have a skew, skew will affect Ling fog.

(2) Production of the core: 6-21 press (1) is made in the form of the core, to ensure that the suction and injection tube aperture and using a small glass rod and the two-phase solid stick, the end of the jet tube Yan a bell for the next process welding.

First the upper and lower ground cover processing is completed (refer to Chapter ways round mouth and with plug), taking the tube length required by firing a round bottom, shown in Figure 6-23 (a), part preparation is ready, draw tube tilt Align the bottom center of the flame regiment, a small mill covered over flat rotation, when the two pillow melting material, the small grinding head over to the round-bottomed Center For dry mouth, slightly pull away from the fire, and then first in the big mouth slightly out of Jane blowing, then the little mill for blowing the cover, rotate burn sandwich joint, should focus on the right hand side of the joint burned over on (to avoid round bottom deformation). To make sandwich bottom flat, both sides must be blowing. Welding and burning holes open siphon bend, shown in Figure 6-23 (2). Put to the flame tip annealing some (not sloppy, the following can not be annealed, but other joints sealing, the flame must not involve the mezzanine connector), near the center of the burn out of bent siphon tube, shown in Figure 6-23 ( 3), burning materials should not be too Ye, bent over quickly when grinding mouth on the big blow to cool (do not rush out of the siphon tube near the centralizer, prisoners out of the bobbin body is cold, such as hot glass touch rearward easy burst). Extraction tube next to the tube after completion of the sealing bends, joints with a small flame can turn annealing number, followed by a slight burning flame aces siphon ring outside, its centralizer, close to the body out of the bobbin, see Figure 6-23 ( 4),

(3) connection: will be ready to slug into the jacket tube, two pillow melting brushed respectively, shown in Figure 6-21 (2). In sub-side end silk pillow melting shrink thick, burning blown ellipsoidal, shown in Figure 6-21 (3). Left-handed tilt, then with a small flame burning in the core, and then pull in addition to more than expected, opening sealing takeover, see Figure 6-21 (4). Annealing while, after cooling the flame burning with a large flat curved outer tube spout site, see Figure 6-21 (5). After cooling explosion unless I expected, left hand grip receivership, with a large flame pillow melting in the mouth evenly, remove from heat immediately into the light work clamp, loosen the sheets into a flat mouth, shown in Figure 6-21 (6), Figure 6-22 (1-4) is one of several better performance of the sprayer. plastic sprayer
