| 摘 要： | 对塔河地区不同造林密度的钻天柳幼林进行生长差异试验的结果表明:2500株/hm2和4400株/hm2密度林分的成活率及当年保存率无显著差异,低密度林分的各项生长性状均好于高密度林分,高密度林分的根长、根直径和侧根数等性状表现更好,多数生长性状差异不显著,造林密度对钻天柳幼林生长状况影响不大。

| Abstract: | The results of growth difference tests on young Chosenia arbutifolia forests with different afforestation densities in the Tahe area showed that there were no significant differences in survival and preservation rates between 2500 plant/hm2 and 4400 plant/hm2 densities.The growth traits were better than those of high-density stands.The high-density stands had better root traits,such as root length,root diameter,and number of lateral roots.Most of the growth traits were not significantly different,afforestation density has little effect on the growth of young plant. |
