| 摘 要： | 通过对寿宁县引种楸树（分根造林）试验区不同坡向、坡位3年生幼树的生长量的调查研究,结果表明：不同坡向、坡位楸树分根造林的平均成活率为97.3%、平均树高为3.26m（其中当年抽高1.12m）、平均胸径3.11cm。通过对比分析,不同坡向、坡位各组楸树树高、当年抽梢高度、胸径之间存在极显著差异,存活率之间不存在着显著差异。种植楸树的坡向应选择南坡为宜,北坡则会影响其生长;种植楸树的坡位应选择下部。

| Abstract: | The growth of three-year-old young samplings of introduced Catalpabungei （reproduction by root cutting） in different aspects and slope position in Shouning County was investigated .Result shows that ：the survival rate of Catalpabungei in different aspects ,slope position are 97 .3% ,the average tree height being 3 .26 m （the height of sprouting being 1 .12 m in the very year ） ,average DBH being 3 .11 ㎝ .Through the contrast analysis ,the tree height ,height of sprouting in the very year DBH of Catalpa bungei in different aspects the slope position has significant differences .The survival rates have no significant difference .The suitable aspect for planting Catalpa bungei should be the south slope .North Slope will affect their growth ;lower slope position should be chosen to plant Catalpabungei . |
