Thinning method is to directly remove branches from the base without leaving wounds on the raw branches. However, the growth effect of the damaged area caused by thinning is weakened for all the trees or their branches that have been evacuated. The thinner the branches, the bigger the wound and the more obvious the weakening effect.
