摘要/Abstract

摘要： 依次按50%,40%,40%的疏伐强度对新建的史密斯桉母树林进行3次疏伐管理后,通过方差分析、多重比较(LSD法)以及相关性分析,研究疏伐频率及疏伐强度对不同种源史密斯桉母树生长影响。结果表明:疏伐频率对不同种源史密斯桉母树高、胸径、冠幅等生长指标的影响具有显著性差异;疏伐频率及疏伐强度与树高、胸径、冠幅的净生长量呈中度及中度以上相关。

关键词: 史密斯桉树, 母树林, 疏伐

Abstract: Based on 3 types of thinning intensities of 50%,40% and 40% and by analysing of variance,LSD(least significant difference) and interdependency,the results of effects of thinning frequency and intensity on growth of Eucalyptus smithii can be drawn. The results show that thinning frequency has prominent difference relation with such growth factors as tree height,breast diameter and crown breadth,and thinning frequency and intensity have extremely interdependency with tree height,breast diameter and net growth of crown breadth.

Key words: Eucalyptus.smithii, seed production stand, thinning
