[0002] Tibet is located on the Qinghai-Tibet Plateau. Its topography, landform, hydrology and climate have resulted in a fragile ecological environment, making governance difficult. Tibet is a vast territory, and ecological construction is an arduous task. In areas such as the North and South Mountains of Lhasa, especially in Lhasa South Mountain Park and the second group of Donggar Community, the terrain is complex, with steep slopes, thin soil layers and a high gravel content. The plateau climate is cold and dry, with little precipitation, which is not conducive to plant growth. The soil has low moisture content and poor water retention. These natural conditions make it difficult for vegetation to grow. In these places, due to the complex terrain and small population, it is difficult to use traditional artificial afforestation methods.

[0003] Currently, the primary method of aerial seeding is to use drones carrying seed pods for broadcast planting. Naked seeds are placed in a container and carried by a drone over the operation area. The pod's outlet is opened, allowing the seeds to fall to the ground under the influence of gravity. However, when the seed outlet is opened, the seeds fall in a vertical line, resulting in a smaller seed distribution area and uneven seeding. Summary of the Invention
