First, the scope of use:

1. Spraying pesticides, insecticide sterilization and foliar fertilization in crops and vegetable greenhouses can also be used in orchards, gardens, forestry, etc.

2. Spray smoke and frost on the spring when the spring is cold.

3. During the apple coloring period, spray cold water on the orchard to cool the orchard at night, increase the humidity, increase the temperature difference between day and night, and increase the coloring rate of the fruit.

4. Prevention and control of pests and diseases in the warehouse, as well as epidemic prevention and disinfection of urban and rural sanitation facilities.

5. Carry out sanitation and epidemic prevention, disinfection and sterilization on the pig house and any place in the pig house.

Second, the use of smoke machine:

1. Refueling: First add 93# gasoline to the fuel tank. The amount of gasoline in the fuel tank should not be lower than 1/3 of the height of the fuel tank. Tighten the fuel tank cap.

2, dosing: add aerosol in the medicine box, prepare a uniform liquid, tighten the lid of the medicine box.

3, start: press the ignition switch with the thumb of the left hand, then press the hand oil pump with the thumb of the right hand until the air in the oil pipe is drained, and the sound of the ignition sound is hoarse (the oil pump is pumped one or two times, press three One of the points will do.) Press the ignition switch with your right hand and pump the air with the pull rod of the left hand pump. When you hear the continuous rumble, you can release the ignition switch and stop pumping. At this time, the machine starts normally. If you restart the machine for a short time, you do not need to pump oil again. If the start is unsuccessful, the gasoline may be too much in the carburetor. Use a gas cylinder to pump the air, blow the oil dry, and then restart.

Third, the preparation method of the drug solution:

The preparation method of the liquid medicine is obviously different from the method of using the ordinary sprayer, and a liquid medicine preparation method is selected according to different conditions.

Method 1. Use 1 liter of diesel/mu to add pesticide directly. No need to add water. After mixing, it can be stratified for a short time. The wettable powder pesticide should be compatible with diesel. After mixing the diesel and the pesticide, the time of no stratification is greater than the spraying time.

Method 2, first mix 4 kg of water plus 1 mu of pesticide, then add 1 kg of aerosol, usually the amount can be. According to the crop density and the height of the plant, the walking speed should be tested first. Make sure the dosage is accurate.

Fourth, note:

1. When using a fog machine, do not use high-toxic drugs to spray smoke.

2, the field of smoke should be selected after the rain or morning and evening, no wind or breeze, wind speed of less than 1 m / s under the conditions of spraying, with gas masks, medicines and hands walking down the wind, to avoid people in the smoke, always keep a distance from the smoke, Be sure to be safe.

3. When starting, there must be no objects or objects within one meter of the front end of the nozzle to prevent high temperature damage. Do not start the test in the room.

4. After shutting down, keep the front of the machine lower than the back, so as to avoid the short circuit and damage of the spark plug and the high voltage block caused by the backflow of the medicine and the spark plug.

5. After the drug fight operation is completed, the remaining liquid must be poured out, and then sprayed out with 2-3 kg of clean water to clean the machine. Otherwise, it is easy to cause the pipe and nozzle to block the effect.

6. If the engine suddenly turns off when spraying, you should quickly open the lid of the medicine box and choose a safety zone to restart it to avoid residual chemicals in the nozzle, resulting in fire and disaster.
