林木养分含量的分析是研究森林物质循环首要条件之一.过去,曾有关于树叶分析的结果,但对于枝、干的分析却不多,连重要造林树种杉木的分析也不多.林木的养分含量即使同一树种也因立地条件、树木年龄和生长季节而变化.但在叶子方面分析资料是很多的.笔者现对秋田和吉野杉木的树体分析结果作如下归纳.
Analysis of nutrient content of forest is one of the most important conditions for the study of forest material circulation.In the past, there was the result of leaf analysis, but few analysis of branches and stems, even the analysis of important afforestation species of Chinese fir is not much. Content Even though the same species varies according to site conditions, tree age and growing season, there are a lot of data on the analysis of leaves. The author now summarizes the tree analysis results of Akita and Yoshino fir.
