摘要
对不同森林培育措施的红松人工林径向生长性质指标进行测试和分析。结果表明 :不同的森林培育措施 (坡位、林分结构、初植密度、间伐 )对红松人工林的生长率、生长轮宽度及生长轮密度有显著的影响 ,对晚材率的影响不明显 ;坡向对红松人工林的生长率、生长轮宽度有显著的影响 ,对晚材率、生长轮密度的影响不明显 ;修枝对红松人工林的生长率、晚材率有显著的影响 ,对生长轮宽度及生长轮密度的影响不明显 ;阴坡、坡下、三株一丛、2 0m× 2 0m、适度间伐、适度修枝的林分林木生长率较高 。
For different silvicultural measures, the radial growth properties of Pinus koraiensis plantations were measured and analyzed. The results showed that the variances of growth percentage, growth ring width(except pruning), growth ring density(except slope aspect and pruning) were remarkable, and the variance of latewood percentage(except pruning) was not significant. In order to increase growth percentage and cultivate the large diameter wood ,the stands on north slope or at the bottom of slope, and with acluster of three trees, density of 2 0?m×2 0?m, properly thinning and pruning could be selected.
