After dissolution, it is also over 1000 times. Powder has 2–3 thousand times. Over 200 fruit trees were sprayed with 1200 Jin of water medicine (44/ mu). There are more trees than trees. There are thousands of…
30 pounds of water and 20 pounds of machine can not be exhausted.
Why do we do this?
1 in the past, every 30 jin each pot. Take the pot as the criterion.
2 now there are gasoline engines and diesel engines. The pressure jet is used. With Jin as the criterion, how much water will be added?
3 aircraft, fogging machine, mist sprayer (early 18 machine). There is no uniform standard.
At present, there is no standard in the world. No professional tests. So they could not tell themselves.
Yesterday, a 1688 said so, because I want to buy one. Explain what a good job is for a long time. There is no specific figure. They could not speak.
In my Agricultural Bureau, cooperatives call for UAVs. No smoke machine.
The dispensing is like this. 100 hectares of paddy field per mu. Mist machine at a time of water per mu. That is to say, add 3 times the medicine.
The UAV has 2 jin of water per mu, which is 50—100 times the amount required. Fog machine, I have not used it difficult to say.
It can only be said that the valuation is [8 minutes per mu. 200 Jin of water per hour, 8 mu. That is to say the ratio is 8 times.
Attention should be given to rice redistribution. Fruit trees are packaged together. Multiply.
