[0002] Thinning is the process of regularly and repeatedly cutting down some trees in immature forests to create a good environment for the remaining trees and promote their growth and development. At the same time, some wood can be obtained through tending thinning. Tending thinning requires different measures according to different conditions of the forest, such as pruning, thinning, and cultivation. Spruce, as a research object of forest tending thinning, has important economic, ecological and scientific significance. Through the study of spruce thinning technology, effective technical support can be provided for forest management and protection, and the sustainable use of forest resources can be promoted.
