Hunan Province has many hills, and most of the orchards are built in hilly and mountainous areas. In the past, the plant protection of fruit trees was artificially sprayed with sprayers, which was time-consuming and labor-intensive. In recent years, plant protection drone for spraying trees have been gradually applied. However, due to the lush fruit branches and the large undulation and drop of hilly terrain, the existing field plant protection drones have problems in the operation of hilly fruit trees, such as inability to penetrate and crashes. The agricultural machinery extension department has been selecting advanced and applicable operating machinery for farmers.
