修枝是为了得到无节圆满的木材,但其副作用会减少生长量。防止修枝引起生长量减少的有效手段是进行间伐和施肥。本研究进行了这方面的组合试验,搞清了由修枝引起的材积生长变化和间伐及施肥带来的影响。
Pruning is done to get round, but its side effects will reduce the amount of growth. Effective measures to prevent prunings from causing a reduction in growth are thinning and fertilization. This study conducted a combination of experiments in this area, identified by the pruning volume growth and thinning and fertilization effects.
