Midu County Deju Township - Plant protection drone flight control operation for pine forest tree insects
Recently, Deju Township of Midu County carried out the control work of 2024 Yunnan pine bark bark by means of drug spraying with a plant protection drone.
In the north forest area of Deju Township, Li Yi Hui, the drone operator of Cloud Nansenye Aviation Technology Co., LTD., controls the plant protection drone to rise slowly, shuttle back and forth along the set prevention and control route in the forest area, and the white atomized drug emitted below the fuselage is evenly sprinkled into the forest. "The distance of our flight defense is controlled below 15 meters, the speed is controlled within 5 meters per second, and the average dosage is 650 milliliters per mu." It works best in the morning and afternoon when the temperature is low and the wind speed is low." Li Yi Hui said
One fifth of Yunnan pine forests are distributed in Deju Township. Silverfish is one of the forest pests. It mainly feeds on the phloem tissue and the topmost pith tissue of the host. In order to effectively prevent and control the spread and spread of silverfish, this year, Deju Township implemented the demonstration project of Yunnan cuttip beetle pest control, and explored the use of plant protection drone drug spray for beetle pest control. The control area is the north forest area of Deju Township and Dayakou Forest area. According to the biological characteristics of silverfish, the control was carried out in June and November respectively, and the control was carried out twice.
"Before this, we mainly used artificial powder spraying, bait wood to kill adults, manual cleaning of dead and dying wood to control silverfish. But manual control operations take a long time, work efficiency is low, and some forest areas are high mountains and deep valleys, the staff can not reach the control." Zhang Yunguang, head of Deju Township forestry and grassland workstation, said, "The plant protection drone has a wide range of drug application, high accuracy, safety and fast, and the work efficiency has been greatly improved, and the disease and pest control effect is good."
Before the flight prevention operation, Deju Township propagandize and inform the villagers through loud speakers, wechat groups, Posting notices at the entrance and exit of the operation area, etc., prohibiting irrelevant personnel from entering the mountain during the flight prevention operation period, and prohibiting livestock grazing in the flight prevention area to ensure the personal and property safety of the masses.
It is reported that it is the first time to use the method of plant protection drone drug spraying to carry out the pest control of Yunnan pine cutter beetle in Midu County. The insecticides used are safe, low toxicity, high efficiency, economic and environmental protection special insecticides for flight prevention, with less environmental impact, which can effectively control target pests and maintain the overall balance of forest ecosystem. Through the plant protection UAV flying control operation, adult insects are killed, insect population density is reduced, disaster losses are reduced, and forest quality and ecological safety are further improved. This also marks that the prevention and control of forestry pests in Midu County has gradually moved from civil air defense to technical defense, and from extensive to precise.
