摘要
为研究南药-橡胶林立体复合种植模式对胶林土壤理化性质的改善作用,筛选最优的南药-橡胶复合种植模式奠定数据基础。采用土壤理化分析法,对海南省儋州市3种南药-橡胶立体复合种植模式(益智-橡胶、葛根-橡胶和砂仁-橡胶)的土壤含水量、pH、有机质、总N、碱解N等理化性质进行了分析比较。结果表明:3种南药-橡胶林立体复合种植模式对7个胶林土壤理化性质产生了显著影响,尤其是土壤有机质含量和全氮含量。PCA分析还表明,砂仁-橡胶和葛根-橡胶是较优的南药-橡胶林立体复合种植模式,其明显改善了胶林土壤的理化性质。
The paper aims to study the effect of herb-rubber intercropping patterns on improving soil physicaland chemical properties, and screen out the best intercropping pattern. Physical and chemical properties, suchas soil water content, pH value, organic matter content, total N and available N were tested by soil physical andchemical analysis under three herb-rubber intercropping patterns. The results showed that the three differentherb-rubber intercropping patterns had a significant influence on soil physical and chemical properties,especially soil organic matter content and total nitrogen content. PCA analysis showed that sharen-rubber andgegen-rubber intercropping patterns were the best herb-rubber intercropping patterns, which had an obviousimproving effect on rubber soil physical and chemical properties.
