| 摘 要： | 以单作茶园和杉木—茶间作茶园为研究对象，测定间作杉木对茶园土壤及茶树叶片重金属元素含量及分布的影响。结果表明：（1）间作杉木可降低茶园土壤Pb、Ni、Mn、Zn元素含量，尤其对Mn有较强吸收能力，其次为Ni、Pb、Zn；（2）间作茶园茶树叶片Pb、Mn、Cu、Zn含量均显著低于单作茶园，说明间作杉木对减少茶叶中4种重金属含量，改善茶叶品质可起到明显作用。

| Abstract: | Effects of intercropping Cunninghamia lanceolata in tea gardens on contents and distribution of heavy metals in the soil and tea leaves were analyzed,through comparison study of a mono-cropping tea garden and an intercropping tea garden.Results show(1) contents of Pb,Ni,Mn and Zn decreased in the intercropping tea plantation,and the absorption capacity of Cunninghamia lanceolata varied from element to element,displaying an decreasing order of Mn>Ni>Pb>Zn;(2) concentrations of the heavy metals in the tea leaves of the intercropping tea garden were significantly lower than in the mono-cropping one.So intercropping of Cunninghamia lanceolata in tea gardens can significantly decrease contents of Pb,Ni,Mn and Zn and improve quality of the tea. |
