摘要: <正>从影响林木生长的环境因子入手,采用数学方法,找出了影响各引种栽培区内1-69/55杨生长的主导气象因子和主导土壤因子。在此基础上,采用数量化方法编制了I-69/55杨立地指数得分表。根据大量的固定标准地和临时标准地资料,经综合分析,提出了1-69/55杨的适宜造林密度和各项丰产栽培技术措施。

Abstract: In this paper, by multivariate regression analysis,authors figured out the leading climateand soil factors affecting the growth of Populus clone 1-69/55. By means of quantitative theory I. Siteindex objective mark table of the clone was divised. Based on the data investigated from a great number of temporary sample plots and permanent plots,some intensive culture models for industrial useswere suggested.
