In order to "prevent insects, prevent dry and hot winds, and prevent lodging", many areas in our county are carrying out artificial spraying of drugs, and the third sub-field of Zhuhu Farm planting and Lefeng Farm have also transferred pesticide spraying helicopters to apply pesticides to farmland, which has attracted many people to stop and watch.
On the morning of August 19, the reporter saw a helicopter hovering over a green rice field in the rice field of Zhuhu Farm, sprinkling pesticides evenly on the rice field through the downward air flow generated by the rotor. It is understood that the traditional manual spraying has high cost, low efficiency and waste of resources. The use of helicopters to spray drugs on crops at low altitude and in large areas is not only low cost, but also achieves the effect of fast speed, wide area and uniform spraying. Lian Qinghong, president of the Hongxing Crop Disease and Pest Control Professional Cooperative in Lefeng Town, told reporters that the area of the two-night flight prevention mission of zhuhu farm accepted by the cooperative this time is 35,000 mu, and it is planned to complete this task in one and a half days. This helicopter sprays pesticides at an average cost of 30 percent less and is 20 percent more efficient than traditional manual spraying.
