Greenhouse vegetable pesticide application to be especially careful
Application of pesticides talk about science, especially in winter greenhouse vegetable pesticide application especially. Otherwise, not only fail to control effect, but also prone to injury. Therefore, the application of pesticides to pay attention to ten bogey.
A pesticide preparation hanged because running water running water impurities, with its easy to plug the low pressure sprayer dispensing nozzle, while also undermine the liquid suspension to produce precipitation.
Two hanged formulated pesticides because well water well water contains minerals more, especially calcium, magnesium and more. These minerals are mixed with the liquid chemical is easy to produce, reduce the efficacy precipitate formed.
Three bogey any excess water will increase the amount of water to reduce the concentration of pesticides. Sprayed on crops, leaving only a very small amount of pesticides, not enough to kill pests, and some pesticides even completely ineffective. Excess water can also cause loss of pesticides, resulting in environmental pollution. Thus,water sprayer in the preparation of pesticides, their use according to the concentration range, strict control of the amount of water.
Four bogey free to increase the amount of pesticide production and sales of pesticides before being allowed to go through rigorous field trials, and then determine dosage, administration time, frequency of administration, the actual use of the data. Therefore, in accordance with instructions on the required amount of pesticide that can achieve the control effect, and increase the dosage not only increased investment, but also to make crops produce injury, increase the amount of pesticide residues in agricultural products, increasing environmental pollution.
Five Note unreasonable application of pesticides can increase some pesticide mixing control effect, reduce the dosage, or reach Cordyceps rid of pests or effect, and mixed use more labor. However, some pesticides can not be mixed use, such as organophosphorus pesticides in most varieties of pesticides encountered alkaline or alkaline medium will quickly decompose and failure. Mix pesticides in need, we must understand the nature of various pesticides, characteristics, to ascertain whether it can be mixed, the best guide for technicians and then mix.

Avoid the use of pesticides seven
1 hanged well water dispensing. Well water contains more calcium, magnesium and other minerals, which react with the liquid easily precipitate, thus reducing the efficacy.
2 hanged sewage dispensing. Sewage containing impurities, after dispensing spray nozzle clog liquid sprayer, while also undermine the stability of the liquid, reduce the efficacy.
3 days temperatures rain avoid spraying. Windy spraying pesticides will drift; rain spraying, liquid rain washed easily reduced efficacy; temperatures spraying, prone to injury and poisoning. Therefore, the best time of application lies in: 8:00 to 11:00, 16:00 to 6:00. Weather permitting, the breeze when spraying.
4 avoid indiscriminate use of pesticides. Should be based on crop type, control objects and agents using the corresponding properties of different pesticides, so that the right medicine, and contraindications blindly increase the amount of pesticide, resulting in increased resistance to pests and reduce the control effect, but also prone to injury.
5, avoid spraying flowering. Spraying of crops and fruit trees in bloom, prone to injury.
6, avoid preharvest manual sprayer spraying. Since pesticide residues in crops to produce, if preharvest spraying, drug residues easily lead poisoning after eating people.
7, avoid a medicine used in conjunction. Long-term use of one or formulations of pesticides, easy to make pest control effect and reduce resistance and therefore should alternate medication.

Water mist system introduced
Definition of water mist
"Mist" (water mist) is compared with the "watersprayer" (water spray) the concept of the so-called mist, is the use of a special nozzle, the water produced by high-pressure water jet particles. In NFPA 750, the mist is defined as: the minimum design pressure at 1 m from the nozzle plane, measured in the thickest part of the water mist particle diameter of not more than 1000μ Dv0.99
Particles according to the size of the water mist, water mist is divided into three, shown in Figure 1. First a mist of Dv0.1 = 100μ Dv0.9 = 200μ connection with the left part, these represent the most fine mist.
Section 2 mist, is the first one with the boundaries of mist Dv0.1 = 200μ with Dv0.9 = 400μ connection between the parts. The high-pressure water mist by nozzle fluid nozzle or nozzles produce many collisions. Because there is a larger water particles with respect to a fine mist, water mist 2 more prone to large traffic.
Section 3 is Dv0.9 mist than 400μ, or the first two water mist to Dv0.99 = 1000μ dividing line between the right part. This mist is chiefly pressure, orifice sprinklers, nozzles and other produce various shocks.
Studies have shown that the mist extinguishing Class B fires particles are less than 400μ are necessary, while the larger particles are effective for Class A fires, which is the fuel to be wetted. Because of this, water mist is defined to include the Dv0.99 to 1000μ. Defined in NFPA 750 mist, both defined in NFPA 15 includes a portion of the water pressure sprayer spraying system (Water Spray), also contains a high-pressure state in a normal spray system (Sprinklers) generated mist. Generally, the fine mist is less than 400μ Dv0.9 mist.

Mechanical grape fertilization
Grape fertilization adhere heavy organic fertilizer, control of nitrogen and phosphorus fertilizer applied. Balanced fertilization is to improve the scientific quality of preserving our unique flavor of grape cultivation measures effective.
Grape growth and development of germination to topdressing fertilizer, reminders of fertilizer, hand pump pressure sprayer fertilizer and other reminders fruit several times a shallow ditch urea and diammonium other fertilizers, timely and appropriate protection of fertilization is to achieve high and stable yield, grape mechanical topdressing fertilizer manner substantially into two. Promotion of our region's special fertilizer equipment is Jinghai "Hefong" brand micro-farming machine supporting fertilizer. The machine uses a shoe opener, power is transmitted to the wheels wheel rotation row of fertilizer fertilizer. Trenching depth, size can be adjusted displacement control, operation of fertilizer uniformly reliable, better. Because of its simple structure, easy processing and low manufacturing costs, many farmers use their inputs after fertilization counterfeit operations. While many farmers use furrow plow turn mattress, after artificial manure fertilizer complex ways and mattress cover applicator surface after mixing soil with rotary tiller rotary method. Operation in various forms, has received little investment,bottle plastic sprayer clever fertilization, the provincial labor, raise efficiency, a multiplier effect.
Vineyards organic fertilizer is soil fertility, soil important means attaches great importance to the majority of growers of organic fertilizer application. Usually chosen pig and chicken manure, 1:2 ratio of preparation, the use of rotary machines and fully fermented compost mixing until the grapes after harvest or spring, with open Goushen Shi (30cm) filling overridden methods was applied. Due to the amount of up to 4000 kg mu fertilization, there are no special fertilizer. Growers can use conditional Shenyang "Taurus" machine, hand buried job ditching machine, artificial deep application filling covered. There is also the applicator surface soil after mixing with rotary tiller among fertilization.

Change measures orchard spraying
1 change spraying habits, improve the quality of spraying fruit trees according to size, leaf number, the reasonable control of water, spraying should be uniform thoughtful, top to bottom, from the inside to the outside, to be sprayed into the back of the blade is liquid, not leak spray, can not re-spray to fully wet leaves, it will not form a flow drops as well, do not leak ulterior motives, leaf with drugs, do not stream does not drip.
2 Improved spraying measures to improve the atomization First minimize the use of manual trigger sprayers, hand sprayers not only labor-intensive, inefficient spraying slow, but pressure is small, poor atomization. Second, the replacement of the spray gun are used, only one injection hole of the lance into two or three of the nozzle orifice, so that good atomization, spraying uniform, no harm to the fruit surface.
3 master spraying techniques to improve spraying sprayer spraying techniques to properly balance the pressure, the pressure is too small, poor atomization; too close, easy to stab the fruit surface. Friends of farmers must be clear, when spraying high-pressure liquid through the orifice after, to go through a distance of 40 cm to completely atomized, so the hand sprayer spraying nozzle and crops must be kept at a distance of about 50 cm. Fog cone angle increases, the finer droplets, on the contrary, the smaller the angle cone fog, mist thicker. Remember, the size of the spray pressure, nozzle angle and distance with the crop is directly related to the liquid spill Tut uniformity and the extent of coverage is good or bad.

Spraying method is the most common method of application
Common methods of pesticide application spray, spray method, applicator method, poured France, drop casting, injection, painting method, dipping method, dressing method, bait method, fumigation, and a dozen.
Spraying method is the most common method of application, that a certain amount of pesticide with an appropriate amount of water dubbed liquid, spraying the liquid spray apparatus into droplets. This method is suitable for cream, liquid, wettable powders, soluble powders, and flowable agent pesticide formulations, both for foliar treatment, but also do soil treatment.
First, a spray method used
According to the amount of liquid per acre spray, spray mist often divided into high-volume, medium volume spraying, low volume spraying, low volume spraying and ULV other categories.
1. High-capacity spray
Coarse spray, also known as high-volume spray, they use a knapsack sprayer type 16 and 36 type motor sprayer spraying, spraying liquid volume per acre more than 40 liters, mostly for 50-75 liters, pesticides, diluted with water, liquid concentration is less than 1000ppm, median droplet diameter of 400 to 1000 microns, a specific spray method. Suitable for high-volume spray water rich agricultural areas and control of plant pests base for soil treatment control weeds, pests on foliage and has a good control effect, but prone to bouncing droplet, rolled leaves, pesticide loss of more that cause soil and water pollution.
2. In the capacity of the spray volume spray, also known as the constant spray, is the use of 16 workers and peasants backpack sprayer and 552 - Hepatitis shoulder-mount sprayer spraying, the spray nozzle aperture diameter of 1.3 to 1.6 mm, the liquid diluted with water , the concentration of 1000ppm or more per acre spray volume in 12.5 to 50 liters, a median droplet diameter of 250 to 400 microns, is a targeted spray. Volume spray is also used in many water areas, pesticide spraying high capacity utilization ratio.
3. Low-volume spray
Low-volume spray, also known as fine spray or mist. With 16 workers and peasants and 552 - Hepatitis sprayers, sprinklers spray containing 0.7 to 1.0 mm aperture diameter for fine spray. DFH type 18 with the use of high-speed air motor sprayer spraying the liquid into the fog often called Mist. Low volume spraying diluted with water and a 0.8% solution concentration to 3% of liquid per acre spray volume from 2.5 to 12.5 liters, a median droplet diameter of 150 to 250 microns, a specific spray and fruit tree sprayer spray drift of the phase combined spray method, to avoid large droplets produced by bouncing rolling phenomenon, and droplet dispersion among the plants, able to achieve an effective pest control droplet coverage density standards. And through plant uptake of pesticides, as well as the plant itself breathing infiltration, transpiration, spit water and other physiological functions, so that pesticides play a role in redistribution. Low-volume foliar spray for control crop pests and diseases, with good control effect, saving pesticide advantages, but not for chemical weed control. Because pesticide use higher concentrations of highly toxic pesticide spraying can not use this method.

Proper use of pesticide sprayers
With efficient appliances spray pesticides and the development of efficient, pesticide application technology is changing, the main trend is to reduce spray volume per unit area, such as the spray from the ground about 50 kg per mu (constant spray), and gradually reduced to mu 1-10 kg (low volume spraying) and 0.5 kg per mu (ultra low volume home garden sprayer spraying), with significantly reduced spray volume, spraying efficiency has been significantly improved.
Low volume spray sprayer spraying method approach is very simple, just put a knapsack sprayer conventional low volume sprinklers tablets. Low volume nozzle piece stainless steel sheet processing, its specification is 0.6-0.7 mm nozzle diameter, flow rate 250 ml per minute. Low volume spraying with a constant spray spray difference is fine, uniform, is a drift of spray, spray volume 1-10 kg acres, liquid evenly cover crops, but not the loss of spray walking speed is generally 1 meter per second.
Effect of the spray
Low volume sprayer spray, the effective spray width of 1.5-2 meters, if 2-3 kg per acre spray volume per acre times need 8-12 minutes, spray 30-40 acres per person per day, increase efficiency than a constant spray more than 10 times, while the intensity of labor is greatly reduced, the control effect with a constant spray fairly.
Spray nozzle points away from crop bottle sprayer spraying the top 0.5-1 m, in the case of 1-3 grade wind, spray hole and wind direction, once every step swing boom, to ensure the effective spray width uniform density within the droplet. Spray volume should have a good relationship with the spray rate, spray volume is generally in acres of 2-3 kg, walking speed of 1 m / sec; acre spray volume of 3-4 kilograms, walking speed of 0.6-0.7 m / sec; 4-5 kg of spray volume mu, walking speed of 0.4 m / sec.

Summer spraying pesticides must pay attention to personal safety
In the pesticide application personnel shall not drinking, smoking, drinking, eating, etc., can not hand Cazui, face, eyes, absolutely not allowed to spray each other frolic. Wash thoroughly with soap after spraying hands, face and mouth, pesticide-contaminated work clothes to be washed and Sunday inch. Daily application personnel garden sprayers spraying time is generally not more than six hours.

Pesticide use process issues that need attention
Pesticide mixture
Tobacco production, some farmers in order to save time and reduce labor intensity, mixed together using several pesticide spraying method. The right mix might improve efficiency and efficacy of pesticides, but confusing mix of pesticides. To rid of pests and mixing several different spraying must take into account the occurrence of each pest and pesticide suitable period of time as well as the persistence of each drug, and only in the event period, spraying suitable period and persistence can be a good match and ensure good medical case mix is reasonably practicable. Otherwise, it will lead to at least a potion mixed useless, in fact, unnecessary wastage, increasing farmers unnecessary financial burden and environmental pressures. Generally, Bordeaux mixture and other alkaline pesticides and biological pesticides bt emulsions should be used alone; conventional organic phosphorus, pyrethroid insecticides, and fungicides can mix conventional; acaricide can include alkaline pesticides, including almost All pesticides.
The use of pesticides and fogging effect dose
The main producing areas of tobacco leaf samples pesticide residue analysis results show that the amount of pesticide residues in tobacco generally higher. Mainly because farmers pressure sprayers spraying unreasonable, arbitrary increases pesticide concentration, increasing the dose, do not use the meter, often with a random amount of caps, resulting in higher levels of pesticide residues in tobacco and environmental pollution and pesticide waste, and Shi easily lead to injury dose increases, the use of highly toxic pesticides greatly increases the risk of poisoning.
Currently spraying machine quality is generally not high, especially sprayer exist "leaking" a serious problem. For decades farmers have been using the traditional manual compression sprayers, garden water sprayer spray large droplets, the loss of a large amount of liquid. And the existence of errors in understanding that only sprayed on tobacco plants dripping liquid in order to obtain the best control effect. Not really need to quit spraying plants thoroughly wet the whole plant, as long as the distribution of pharmaceutical active ingredients uniform deposition, will be able to play a good efficacy. Promoting tobacco production of large purchase knapsack sprayer (such as Tarzan -18), using a fine mist blower spraying technologies to improve control effect and reduce pesticide use.

Only 3 liters of water can wash cars
This is not a "fantasy", but the latest environmentally friendly car wash operation. Recently, this drop in the bucket "new" method appears in a new car wash Mudu town - no taps, no high-pressure pump, a full set of equipment carts or back in the body can be taken away.
This environmentally friendly car wash method caused the local private owners of great interest, they sit at home and make a phone call you can enjoy the convenience of car wash services. However, this new technology is facing a "quasi-born" awkward - and traditional car wash industry as too different departments temporarily unable to define its nature, how to become a problem for approval.
Green Car Wash optimistic entrepreneurs
Yang Feng Xiong, Mudu Town landless peasants, in the town opened a massage by. Massage are in the business, while Yang has been thinking about expanding their entrepreneurial path.
In January, a chance, Yang Xiong Feng saw the CCTV news channel a report: Beijing there is a trolley-style washing machine, water tank capacity of 60 liters, a box of water to wash 20 Sedan wash a car costs only a few cents; And it is not only reflected in the province's environmental water,garden hand sprayers which is driven by solar cells; Beijing a lot of laid-off workers, adding to push the car wash in the army.
Yang Feng Xiong was on the heart, and think this is an entrepreneurial path. He started the car wash industry wide environmental investigation, commissioned by Japan, Germany and foreign friends to inquire about the situation, but also personally went to Beijing, Shanghai, Nanjing, Shandong and other places to investigate.
In May this year, Yang Feng Xiong started registered company, and from the Beijing Zhongguancun an environmental technology company bought back two water-saving washing machine, manual sprayer access to the technology in Suzhou area exclusive rights.
Yang Feng Xiong Mudu town in Palm Cove rented a facade cell door, trying to run his green car wash business. Car wash equipment can be pushed, do not need a fixed site, residential private owners are just a phone call, the workers immediately pushed the washing machine door service. This novel technique has attracted a convenient car wash Palm Bay residents are of great interest to the present, Yang Feng Xiong already has nearly one hundred regular clients.

Classification of water mist extinguishing system
Mist nozzles, containing one or more orifices, means can be atomized droplets, which is the most critical parts of the system.
Produce water mist nozzles principle particles of the following five methods, the liquid with respect to the surrounding air is released at high speed, because the speed difference between the liquid and air and water particles to be shredded; liquid touch to a fixed surface, to produce water particles due to collision; two shares a similar flow components collide particles per water flow are formed; electronic ground vibration or liquid particles into water (ultrasound and electrostatic atomizer); liquid in a pressure vessel is heated to above its boiling point, atmospheric pressure is suddenly released to the state (liquid sprayer burst).
Hydraulic calculation, low-pressure system similar to the ordinary sprinkler system, according to Hazen-Williams formula, medium pressure, high pressure system according to Darcy-Weishach formula. As the flow rate, temperature, viscosity and pipe roughness coefficient greatly affect the degree of turbulence of water, thus affecting the pipeline pressure loss, and HW parameters of the above formula can not be amended. Under normal circumstances, especially in high-pressure water mist system, compared with low pressure water mist systems are more prone to higher flow rates.
Water mist system works with water sprayer system is similar to a typical system works: automatic startup state, the protection zone set up multiple detectors, when a fire occurs, the system control panel to accept the signal detector detects movement, spray the fire area; manually start state, the protection zone set up multiple detectors, when a fire occurs, the detector alarm signal or personnel at the scene confirmed the fire, open fires in the area recently set manually at boot device ( Manual and automatic switching type), start the water mist system to spray the fire area.
Water mist system is similar to automatic sprinkler, fixed water spray, carbon dioxide and halon fire extinguishing system, in many ways, these systems can be seen as comprehensive. In general, water mist system is the use of water as extinguished, fire suppression and control of the media, but different from the traditional way to achieve.

Causes and Countermeasures injury
With the development of science and technology, the scope and use of herbicides rapidly expanding area. Herbicide injury generation has become a universal phenomenon, not only caused serious loss of crop yield, but also bring social problems, has attracted attention of all levels of government.
Herbicide injury causes are many, there is the nature of the herbicide itself; have an adverse impact of climatic conditions; farm sprayer sensitive period with crop fertility problems; also does not regulate pesticide applicators problems posed. These problems are sometimes alone, sometimes overlap occurs, it is difficult to distinguish between major and minor. Because of space limitations articles without detail.
Basic Strategy: research workers should be developed more secure, easier to use herbicides; manufacturers should be strictly according to the standard herbicide production of qualified products; pesticide distribution, agricultural extension shall master the relevant knowledge of herbicides for farmers to strengthen technical guidance; bottle sprayer farmers and friends should also be actively learning technology knowledge to improve herbicide relevant knowledge and use of technology, so as to avoid or reduce the incidence of injury.

According to the herbicide used to kill grass characteristic selection period
Chemical herbicides have different biological activity and herbicidal methods, therefore, must make good use of its features herbicides, in order to obtain the desired control effect.
Such as: acetochlor: amide herbicides to absorb coleoptile main control annual grass weeds and some broadleaf weeds in small grain seed, closed with a certain role. After sowing in wheat crop soil to stand needle enclosed use, the herbicidal effects influenced by soil moisture, drought conditions not conducive to the efficacy of the play,pressure sprayers the herbicidal effect is poor, when the rain water in field after application when they prone to injury.
Isoproturon: herbicides, some of the main controlling grass weeds and some broadleaf weeds (good effect on the chickweed), preemergence, postemergence can use, but early postemergence use works best. In wheat (barley) after sowing bud to 4 leaf stage. Isoproturon efficacy of play is also affected by the impact of soil moisture, drought conditions using ineffective, postemergence than preemergence use.
Fenoxaprop, alkynyl oxalic acid, both foliar treatment agent, no closure effect, which can only be carried out after a homogeneous weed foliage treatment.
Tribenuron: herbicides, in order to absorb the main stem, the role of both closed, the main control broadleaf weeds in the 3-4 leaf stage of weed works best. Because of its dead grass is slower, in order to expand the spectrum herbicide, dead grass to improve the speed, multi-yl grass with ketones, MCPA ,2.4-D, Fluoroglycofen ether compound used.
Azole oxadiazon: leaf contact insecticide, no sucking conductivity, for the control of broadleaf weeds, when a large amount of wheat leaves burns phenomenon, dead grass fast, but weeding recur, and for chickweed, large nest vegetables less effective, with tribenuron, MCPA and other compound used in the 3-4 leaf stage of weeds best.
Glyphosate is the uptake and Herbicide. Can use its uptake, 5-7 days before the grain filling fruit tree sprayers spraying, control wheat reed good effect, no influence on the grain filling.

Pesticide spraying methods more scientific grasp the main points
Spraying method is the most common method of application, that a certain amount of pesticide with an appropriate amount of water dubbed liquid, spraying the liquid spray apparatus into droplets. This method is suitable for cream, liquid, wettable powders, soluble powders, and flowable agent pesticide formulations, both for foliar treatment, but also do soil treatment.
First, a spray method used
Per acre (667 square meters) the amount of spray liquid, aerosol spray method often divided into high-volume, medium volume spraying, low volume spraying, low volume spraying and ULV other categories.
1, high-volume spraying
Coarse spray, also known as high-volume spray, they use a knapsack sprayer type 16 and 36 type motor sprayer spraying per acre (667 square meters) the amount of more than 40 liters of liquid spray, mostly 50 to 75 liters of pesticides diluted with water , liquid concentration of less than 1000 mg / kg, the median droplet diameter of 400 to 1000 microns, a specific spray method. Suitable for high-volume spray water rich agricultural areas and control of plant pests base for soil treatment control weeds, pests on foliage and has a good control effect, but prone to bouncing droplet, rolled leaves, pesticide loss of more that cause soil and water pollution.
2, the capacity of the spray
In volume spray, also known as the constant spray, is the use of 16 workers and peasants backpack sprayer and 552 - Hepatitis shoulder-mount pressure sprayers spraying, spray nozzle aperture diameter of 1.3 to 1.6 mm, the liquid diluted with water, the concentration in 1000 mg / kg or more per acre (667 sq.m.) spray volume of 12.5 to 50 liters, a median droplet diameter of 250 to 400 microns, is a targeted spray. Volume spray is also used in many water areas, pesticide spraying high capacity utilization ratio.
3, low-volume spray
Low-volume spray, also known as fine spray or mist. With 16 workers and peasants and 552 - Hepatitis sprayers, sprinklers spray containing 0.7 to 1.0 mm aperture diameter for fine spray. DFH type 18 with the use of high-speed air motor sprayer spraying the liquid into the fog often called Mist. Low volume spraying diluted with water and the solution concentration of 0.8 to 3% per acre (667 square meters) of 2.5 to 12.5 spray liquid L, median droplet diameter of 150 to 250 microns and a targeted weed killer sprayer a combination of spray drift spray way to avoid large droplets produced by bouncing rolling phenomenon, and droplet dispersion among the plants, able to achieve an effective pest control droplet coverage density standards. And through plant uptake of pesticides, as well as the plant itself breathing infiltration, transpiration, spit water and other physiological functions, so that pesticides play a role in redistribution. Low-volume foliar spray for control crop pests and diseases, with good control effect, saving pesticide advantages, but not for chemical weed control. Because pesticide use higher concentrations of highly toxic pesticide spraying can not use this method.

PE spray bottle bottle bags technical defects can be improved through
From Germany developed a new bottle bags technology in improving PE bottle sprayer defects play a huge role. The new technology with bottle bags and ordinary airless spray structure :: blow molding bottle; bags; injection molded gaskets; and connectors using fewer raw materials. For disinfection of medical products and demanding that 1,000 mL spray bottle filled with new bags from a rigid PP outer bottle with DuPont's Surlyn and a soft inner bag made of composition.
PE bottle bags technology through a spray bottle contains is an independent, while use manually put aluminum foil bags stuffed airless bottle extrusion / blow-molded high-density PE spray bottle. Put a connector soldered to the foil bag before, creating a gasket.
While the new structure simplifies the handling of waste after recycling, because the bottle and bags are made of the same polymeric material made of. Top of the bottle with a trigger sprayers, but also a mechanical treatment to produce the bottom of the ventilation holes. Without pierced with ventilation holes inside the bag, the bag part of the separation, ensuring a press pump departure controller, the bag can be flat down. The use of the bottle, can improve the efficiency of 60%.

Classification of plant protection machinery are also diverse, usually by spraying pesticide formulations types, uses, supporting power, mode of operation, carrying and delivery methods to classify:
1, according to the formulation and use of pesticide spraying divided sprayers, dusters, smoke machines, sprinkle capsules machines.
2, supporting power divided by manpower plant protection machinery, animal plant protection equipment, small power plant protection machinery, electric traction tractor or large plant protection equipment, aviation equipment and other plant protection. Human-powered application equipment generally known chemical sprayer, dusters; motorized sprayer spraying equipment generally known, dusting machines.
3, by means of delivery of a handheld, shoulder-mount, backpack, portable, stretcher-type, push-type, tractor trailer, tractor suspension and self-propelled and so on.
4, according to how much can be divided spray volume constant spray, low-volume sprays, ultra low volume spray equipment.
5, can be divided by atomization or hydraulic sprayer, air permeability sprayer, thermal spray machines, centrifugal sprayer, electrostatic spraying machines.
In short, the classification of spraying equipment in many ways, more complex, often the name of one kind of equipment contains several different categories of synthesis.
