In the early morning of November 29, above the natural woodland of Shihu Park in Shizong County, a multi-rotor drone shuttled back and forth, and the bottom was constantly sprayed with fine water mist, and under the influence of the air flow generated by the rotor, it was evenly sprayed on the pine trees below.
According to the investigation of the technical personnel of the Forestry and Grassland Bureau of Shizong County, the natural forest near Shihu Park is being seriously damaged by diseases and insect pests such as the small beetle in Yunnan, and some trees have dried up and died, but because the trees are relatively tall and the terrain of the forest area is complex, it is difficult to use traditional pesticide spraying technology to control diseases and insect pests. Yunnan cut-off beetle is a genus of insects, coleoptera, small beetle family. It is distributed in Liaoning, Henan, Shaanxi, Jiangsu, Zhejiang, Hunan, Sichuan, Yunnan and other provinces, mainly for The Chinese pine, alpine pine, oil pine, Yunnan pine and other pine species. Adult larvae are infested under the skin of moths, mainly in the branches and shoots of weakened or newly transplanted trees. It is mainly a kind of dried moth pest that mainly harms Yunnan pine and Huashan pine in our county.
In view of this situation, the pest prevention and quarantine station of the county forestry and grassland bureau cooperated with Yunnan Forestry Company to carry out the implementation of unmanned aerial vehicle spray prevention operations by purchasing third-party services.
It is understood that the implementation of the flight defense operation area of more than 1300 acres, the use of a UAV operation can complete all the prevention and control work within two days, the UAV spraying pesticides is not only water-saving efficiency, the air flow generated under the aircraft rotor can also make the chemical solution more evenly distributed to the leaves and stems of plants and soil. The sprayed pesticides are strictly proportioned and harmless to the human body. This is also the first time in Qujing area that drones have been used for natural forest disease and pest control on a large scale.
The original traditional manual control of some deep mountain forests in the people can not enter, some of the prevention and control can not be in place, but the use of unmanned aerial vehicles can achieve no dead end coverage.
