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.
