Herbicide application technology

China's current production of manual sprayer according to its structure and working principle can be divided into two categories: compression type to 3WS-7 mostly; backpack type to 3WB-16 type (type 16 workers and peasants) based. They are simple in structure, easy to use, easy to maintain, and inexpensive. Sprays of 500-700 liters (35-50/liter) per hectare can be used to spray pre-emergence soil treatment and contact-killing post-emergence shoots and leaves herbicides. If a low-volume nozzle with a 0.7-mm aperture is installed, low-volume sprays can also be used. The spray volume is 75-150 litres/ha (5-10 liters/mu), and spray-applied stem-leaf herbicides can be sprayed. First, adjustment 1, drug inspection. Add water to check for leaks at the junctions of the kit and sprayer. 2, flow measurement. Pour clear water into the medicine box, select a certain pressure, turn the manual switch on for one minute, let the liquid medicine flow into a container, and measure with a meter. 3, the effective spray amplitude measurement. According to the actual field operation, the soil is sprayed according to the actual width of the ground. If the post-emergence shoots are low-volume spray, 2.5 kg/cm2 pressure may be used. The sprayer may be at a distance of 0.5-1 m from the crop. The wind direction was the same. The spray bar was turned on and turned on for half a minute. The width of the spray on the leaf surface of the plant was observed. This width was used as an effective spray pattern. The best choice for the nozzle is a fan-shaped nozzle. When spraying, set the height, pressure, and speed of the nozzle. Do not shake it around to ensure even spraying. 4, line speed calculation General walking speed is 1.0-1.3 meters / second. Second, the liquid preparation 1, the kit plus half a bucket of water. 2, the preparation of mother liquor, such as the mixture of two drugs to be prepared in the two containers in the mother liquor; if it is a wettable powder preparation of mother liquor, you should first add a small amount of water in the container, dosing while stirring, must not be a drug excessive. 3, the mother liquor of the wettable powder is added to the medicine box first, and the mother liquor of the emulsified oil is the medicine box. 4, if you need to add additives, then add additives. 5. Fill the kit with water. 6. Shake by hand to mix the liquid. Third, the field operation before the application of the first observation direction, pay attention to the direction of the nozzle should be consistent with the direction of the wind, and wind perpendicular to the direction, or not less than 45 degrees; spray sequence first in the wind under the block outside the application, to avoid contact with liquid medicine. When the pressure reaches a predetermined value, the switch is turned on and sprayed at a predetermined speed. At the same time, keep the leeward hand to take the spray bar and spray it in the same direction as the wind direction. When the first spray is sprayed off, close the switch, go to the second spray station, and spray the spray in the other hand. The pressure and speed must be consistent when spraying, and the direction and height are stable. Pay attention to changes in wind speed and direction and adjust in time to ensure the quality of the spray. After spraying the medicine, wash the medicine box, spray bar, sprayer, and hose and other parts with clean water and dry the medicine box. Matters needing attention: 1, do not add liquid medicine too full, use must close the medicine box, so as to avoid liquid leakage or shake out. 2, after the back of the sprayer should stir the rocker 6-8 times, so that there is a little pressure in the air chamber, open the switch, and then hit the side spray. The pressure in the air chamber should not be too high, and the spray should be good. 3, spraying herbicides best fan-shaped nozzle, spray a ridge, ridge application.
