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)的土壤理化性质进行了研究。结果表明:秃杉幼林不同间作模式土壤物理性质存在差异,其中秃杉—旱谷、秃杉—小米、秃杉—玉米和秃杉纯林0~20 cm土层容重分别为0.93、0.97、0.95和0.98 g/cm3、毛管孔隙度分别为56.79、54.70、54.89和57.07 g/cm3,非毛管孔隙度分别为7.16、6.58、7.38和6.25 g/cm3。与秃杉纯林相比,3种间种模式土壤有机质、全N、水解N、全P和速效P含量均呈现增大趋势。表明秃杉幼林间种农作物能够改善土壤结构和水分状况,提高土壤有机质和主要养分含量。

摘 要：
The soil physicochemical properties in four patterns of Taiwania flousiana—crop intercropping(T. Flousiana—Oryza sativa, T. flousiana—Setaria italica, T. flousiana—Zea mays,and pure stand of T. flousiana) were studied in Nandan Shankou Forestry Farm of Guangxi,China. The results indicated that there existed differences in the soil physical properties among four patterns of T. flousiana—crop intercropping. The density, capillary porosity and non-capillary porosity of the soil(0~20 cm) were 0.93 g/cm3, 56.79 %, and 7.16 % in T. flousiana—Oryza sativa pattern, 0.97 g/cm3, 54.70 % and 6.58 % in T. flousiana—Setaria italica, 0.95g/cm3, 54.89 % and 7.38 % in T. flousiana—maize,and 0.98 g/cm3,57.07 % and 6.25 % in pure stand of T. flousiana. Compared to the pure stand of T. flousiana,the content of organic matter,total N, hydrolyzable N,total P,available P and total K of the soil(0~20 cm) in three patterns of T. flousiana—crop intercropping have also increased. It showed that T. flousiana—crop intercropping could improve soil structure and moisture condition,increase the content of soil organic matter and nutrients.
