不同间作物对茶园土壤养分的影响

Effects of Intercropping Different Crops in Tea Garden on Soil Nutrients

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 slightly 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.
