摘要
在天然马尾松采脂林中进行高产脂优树选择，应用１～５株５种优势木对比法进行比较分析，确认３株优势木对比法的调查性状变异系数小、精度高，主要产量指标精度均可达到８３％以上，选择效果好．
Proceeding to the methods of comparison trees with one,two,three,four and five trees,this article discussed the selection method of masson pine(Pinus massoniana Lamb.)plus trees with high yield of resin in natural stands.The results showed that comparison method with three trees was considered as a suitable method whose C.V of investigating was the least and the precison was the highest.So,the mothed of three trees can be used in practice.
