为了探明林茶间作对茶园土壤养分的影响,以不同间作茶园的土壤为材料,以单作茶园土壤为对照,采用土壤常规分析方法分别测定其中的主要营养成分.结果表明:间作沉香的茶园土壤,N、P、K含量略低于单作茶园,但有机质含量提高了14.7%;间作野花椒的茶园土壤,N、P、K和有机质含量分别提高了12.7%、22.9%、17.4%、7.2%;间作香樟树的茶园土壤,有机质和速效钾含量分别增加了3.8%、8.4%.说明,进行林茶间作对改善茶园土壤性质有重要作用.%In order to verify the effects of forest-tea intercropping on the soil nutrient in the tea garden , main nutritional components were separated from different tea gardens according to conventional method. The contents of the N , P, K in the Thyelaeaceae intercropping tea garden was alightly lower than those in pure tea plantation , but the content of organic matter increased 14. 7 ％ . The contents of N ,P, K and organic matter increased 12. 7 ％ , 22. 9 ％ , 17. 4 ％ and 7. 2 ％ by interplanting Zanthoxylum utile Huang. The contents of organic matter, available potassium increased 3. 8 ％ and 8.4 ％ by interplanting Cinnamomum camphora. The results indicated that forest-tea intercropping was influential role to improve the soil in the tea garden.
