The formulation method is different for different herbicide formulations. For example, emulsions, liquids and suspensions can be prepared by one-step dilution method, that is, a certain amount of herbicide is directly added to the sprayer for dilution; the wettable powder, dry suspoemulsion and the like must be prepared by a two-step dilution method: The step is to accurately weigh the herbicide according to the requirements, add a small amount of water and stir it to make it fully dissolved. The second step is to uniformly dilute a certain amount of mother liquor into the quantitative water. To prepare the diluent in the sprayer, you must first add about 10 cm of water to the sprayer container, slowly add the medicament or mother liquor, and then add water to the water line, but not fill it up, such as filling the sprayer kit When the pesticide is walking, the liquid in the medicine box is difficult to shake, and the medicine is likely to sink or float, affecting the uniformity of the liquid and affecting the herbicidal effect. Moreover, when the pesticide application is applied, the liquid medicine is easily splashed from the mouth of the container and caught on the application personnel, posing a safety hazard. In addition, because the specific gravity of various herbicides is not the same as the specific gravity of water, spray immediately after the liquid is dispensed, and do not stay. Spray Method Manual sprayer Low-volume spray method is very simple, just replace the conventional knapsack sprayer with a low-pressure spray head. The low-profile nozzle piece is made of stainless steel. The specification is that the nozzle hole diameter is 0.6~0.7mm, and the flow rate is 250ml per minute. The difference between the low-volume spray and the constant spray is that the spray is fine and uniform. It is a drifting spray. The amount of liquid sprayed per mu is 1~10 kg. The liquid evenly covers the crop but does not lose. The spray walking speed is generally 1 meter per second. Spray effect manual sprayer low-volume spray, its effective spray width is 1.5~2 meters, if it takes 2~3kg per mu, the spray volume is 8~12 minutes per acre, and each person sprays 30~40mu per day, the ergonomic ratio is constant. The spray is increased by more than 10 times, but the labor intensity is greatly reduced, and the control effect is equivalent to that of the constant spray. When the spray point is sprayed, the nozzle is 0.5~1 m from the top of the crop. In the case of 1~3 wind, the spray hole is consistent with the wind direction, and the spray bar is swung once every step to ensure uniform density of the spray droplets in the effective spray width. The relationship between spray volume and spray speed should be mastered. Generally, the spray volume of mu is 2~3 kg, the walking speed is 1 m/s; the spray volume is 3~4 kg, and the walking speed is 0.6~0.7 m/s; The spray volume of mu is 4~5 kg, and the walking speed is 0.4 m/s.
