摘要
根据红松人工林多年不同抚育间伐强度及种材兼用林试验的效果分析,表明红松人工林在适当林龄阶段,加大抚育间伐强度,采取截干措施,对培育速生优质大径用材及增加红松培育周期的种子产量有明显的促进作用,是森林分类经营后,建立高效红松商品林的重要措施。
Basing on the analysis of effect of Korean pine plantation for different tending-intermediate cutting and forest exploited both seed and timber, the result showed that it had obvious effect on cultivating large-diameter timber and increasing seed output by means of increasing tending-intermediate cutting strength and adopting pollarding measure. It is an important measure that builds efficient commercial forest.
