| 摘 要： | 本文通过对５年生杉木幼林套种三年桐模式的土壤肥力测定分析结果表明：套种林地土壤水分状况、孔隙状况和土壤结构体均较杉木纯林有所改善；０～２０ｃｍ土层渗透系数比杉木纯林增加１．９５ｍｍ／ｍｉｎ；套种模式土壤养分含量有所提高，０～２０ｃｍ土层有机质比杉木纯林增加０．６１％．这说明杉木幼林套种三年桐林分具有较强的培肥土壤和水源涵养作用．

| Abstract: | In this paper, analysis on soil fertility on five-aged young Chinese fir site interplanted with Tung oil tree, compared with pure Chinese fir stand, the results showed that soil moisture condition, pore condition and structure had a certain improvement, the permeation coefficient of 0～20 cm soil layer increased by 1. 95mm per minute, soil nutrient content increased by interplanting, the organic matter of 0～20cm soil layer increased by 0. 61 %,therefore, the Chinese fir stand interplanted with Tung oil tree had stronger function of improving soil fertility and water conservation. |
