摘要
根据12块杉木人工中龄林标准地试验所得数据,运用方差分析及多重比较的方法,比较分析了施肥、抚育间伐、施肥+抚育间伐3种抚育措施对杉木生长量的影响。结果表明:施肥+抚育间伐对杉木人工中龄林的生长量影响最大,是杉木人工中龄林经营管理的较佳措施,从而为杉木人工中龄林的集约经营管理模式选择提供实践依据。
Based on the investigation of 12 sample plots, this paper analyzed the effects of the different managements （fertil- izer application, thinning, and fertilizer application plus thinning） on stand volume of Cunninghamia lanceolata （Lamb.） Hook plantation in middle age. The results showed that the management of fertilizer application plus thinning had a great influence on stand volume of the plantation, and considered to be the best way for intensive management of middle-age Cunninghamia lanceolata （ Lamb. ） Hook plantation.
