| 摘 要： | 依据17龄意大利214杨随机区组设计的不同密度，根据树高和胸径生长量用林业统计软件进行蓄积计算，用不同密度下的立木蓄积量来确定最佳的造林密度。试验结果表明，4m×6m试验密度尽管单株蓄积不是最高的，但公顷蓄积是最大的，为260．74m^3·hm^-2，该密度林分林木符合大径材标准的株数最多，为87株。因此4m×6m密度是较为丰产的最佳密度。

| Abstract: | Based on different densities of 17-year-old Populus euramevicana cv.'i-214' by randomized block design,according to tree height & DBH increment,using forestry statistical software to conduct volume calculation,optimum planting density were determined by stock volume under different densities.Result shows that: although volume per tree under experimental density of 4 m×6 m is not the highest,but the timber volume per hectare is the biggest,being 260.74 m3·hm-2;trees in the forest with this density according with big-diameter timber standard is the most,being 87 trees.So density of 4 m×6 m is optimum density with high-yielding. |
