摘 要：
对广西南丹县山口林场4种秃杉幼林间作模式(秃杉-旱谷、秃杉-小米、秃杉-玉米和秃杉纯林)的林木生长状况和经济效益进行了比较分析。结果表明:(1)与秃杉纯林相比,秃杉幼林间作均在一定程度上促进林木生长,且增长作用随林龄增加而增大;但间作模式对秃杉幼林造林成活及保存率影响不大。(2)各间作模式较纯林相比均获得较好的经济收益,不同间作模式2年内纯收益从大到小的排列顺序是:秃杉-玉米>秃杉-旱谷>秃杉-小米。因此,在秃杉幼林地间种农作物可以有效地利用土地,促进秃杉幼林生长,提高林地的经济效益。

摘 要：
The tree growth and economic benefit of four intercropping patterns of Taiwania flousiana( T. flousianaupland rice, T. flousiana-millet, T. flousiana-maize and pure forest) were comparatively analyzed in Nandan Shankou Forestry Farm of Guangxi province. The results show that:( 1) Compared to pure forest,intercropping patterns can promote the growth of T. flousiana to a certain extent,and the growth effect increases with the increase of forest age; but it affects lightly on survival rate and preserving rate of T. flousiana young plantation.( 2) All of three intercropping patterns have better economic benefits than pure forests,the sequence of net income within two years is T. flousiana-maize > T. flousiana-upland rice > T. flousiana-millet. Therefore,intercropping patterns not only promote the growth of T. flousiana young plantation,but also increase economic benefits.
