| 摘 要： | 进行了3种不同遮荫度(遮荫度为50%的黑色遮荫网、遮荫度为80%的黑色遮荫网和不遮荫即对照)对24月龄云南红豆杉苗木生长量影响的试验研究,经方差分析和多重比较分析结果表明,遮荫度为50%的黑色遮荫网对云南红豆杉苗木的苗高、地径、茎鲜重、枝鲜重、地下部分鲜重、主根径、主根长7个生长指标表现最佳,可在云南红豆杉苗木初期培育生产中大量推广使用.

| Abstract: | The research about the experiment of the impacts of 3 different shading degrees has been done on 24-month aged Taxus yunnaneusis seedlings＇ growth. The result by variance analysis and multi-eom- parison reveals that the black net of 50% shading degree is optimum for seedling＇ s height, diameter, branch weight, underground weight, main root diameter and root length of Taxus yuuuauensis. |
