国营林场抚育间伐不仅培育了森林,提供了木材,增加了国营林场的经济收入,而且能提高林分直径生长量和经济出材率,促使林木早日成材。目前我省国营林场有120多万亩中幼林急需抚育间伐,但由于不少地方对抚育森林存在单纯利用木材和舍不得间伐的两种倾向,影响了森林生长率的提高,已成为急需解决的关键技术问题。根据我省抚育间伐实践现综述于后。
Thinning of state-owned forestry farms not only nurtured forests, provided timber, increased the economic income of state-owned forest farms, but also increased stand diameter and economic timber yield to promote the early success of forest trees. At present, more than 1.2 million mu of young and middle-aged forest in state-owned forest farms are in urgent need of tending and thinning.

According to the practice of tending thinning practice in our province is summarized later.
