摘要

为了解我国毛乌素沙地北沙柳种质资源的生长状况以及北沙柳部分性状的分类和分布规律

对北沙柳种质资源进行科学的管理以及有效的利用

采用样线法与随机抽样相结合的调查方法

对我国毛乌素沙地北沙柳的生长发育状况进行现地调查

确定了我国北沙柳的主要分布区。采用数理统计的分析方法分析了北沙柳部分性状的变异情况及其生长现状。(1)北沙柳灌丛高度和冠幅均符合正态分布

冠幅变异幅度大于灌丛高度变异幅度。(2)不同种源区北沙柳灌丛高度差异显著

冠幅差异不显著。(3)不同种源区北沙柳的扦插成活率差别较大。

Abstract

The main purposes of the study are to understand the growth situation of Salix psammophila germplasm resources and the classification and distribution of traits in the Mu Us sandy land in China and manage and use the Salix psammophila germplasm resources

scientifically and effectively. In order to determine the main distribution area of Salix psammophila

line transect method combined with random sampling survey method is used. Mathematical statistics is applied to analyze the variation of Salix psammophila and its grow th status. Survey results are as follows: ( 1) The height and crown range of Salix psammophila are in line with normal distribution and the variation range of crown range is greater than height . ( 2) Salix psammophila in different origin areas has significant difference in height

but no significant difference in crown range. ( 3) Salix psammophila in different origin areas differs in survival rate of cutting.
