抚育间伐对速生杨人工林生长的影响

Effects of Tending Thinning on the Growth of Fast-growing Poplar Plantation

试验研究了不同抚育间伐方法对速生杨人工林平均胸径、单株材积和林木健康状况的影响。结果表明:间伐两年后,平均胸径生长量、单株材积和林木健康状况都是隔行间伐>隔株间伐>对照。

This paper studied the effects of different thinning methods on mean DBH, volume ofindividual tree and health of fast-growing poplar plantation. The results showed that mean DBH,volume ofindividual tree and health were in the order of interlaced thinning〉septum strain thinning〉CK after thinning of two years.
