| 摘 要： | 桉树人工林间种山毛豆对提高土壤肥力和促进林木生长有极其显著的作用。间种5年后，林地表层土壤有机质和全量养分N、P、K的质量分数，分别为18．21kg／hm^2、0．85kg/hm^2、0．43kg／hm^2、1．30kg/hm^2，而对照林地分别为13．70kg/hm^2、0.56kghm^2、0．34kg/hm^2、1．10kg/hm^2；林地土壤有效养分含量显著提高；土壤结构和土壤水分物理性质显著改善；桉树生长量显著增加，刚果W5桉平均株高增长16％，平均胸径增长22％，单位面积的木材蓄积量增加59％。

| Abstract: | Experimental results show that the interplanting of Tephrosia candida in the eucalyptus plantation can significantly enhance soil fertility and promoting tree growth. After 5 years interplanting, soil organic matter, total N, total P, and total K is 18.21 kg/hm2, 0.85 kg/hm2, 0.43 kg/hm2, and 1.30 kg/hm2, respectively, while that of the contract is 13.70 kg/hm2, 0.56 kg/hm2, 0.34 kg/hm2, and 1.10 kg/hm2 respectively. The interplanting also arise the available nutrient contents, improve soil structure and soil water physical property. As a result, the average height of trees is increased by 16%, average diameter at breast height by 22%, average volum of wood by 59%. |
