摘  要：
为促进贵州鸟王茶茶叶生产的可持续发展,为茶园改造、科学规划建设新茶园、改良土壤条件和进一步改善茶叶品质提供科学依据,分析了贵州鸟王茶不同茶园和不同生态环境中土壤重金属元素(Hg,As,Pb,Cu,Cr)的含量特征,并以无公害茶叶产地环境条件中土壤环境要求为背景值对其进行单项和综合污染指数评价。结果表明:各个重金属元素在不同茶园和不同生态环境中都有差异,Cr、Pb、Hg和Cu之间存在显著或极显著的正相关关系。贵州鸟王茶产地土壤5种重金属含量比较低,均符合无公害茶园土壤环境质量标准,单污染指数和综合污染指数均小于1.0,鸟王茶产地土壤质量良好。

摘  要：
In order to promote the sustainable development of Niaowang tea production in Guizhou and provide the scientific basis for tea plantation reconstruction,scientifically planning and building new tea plantations,improving soil conditions and tea qualities,the characteristics of concentrations of five heavy metals(Hg,As,Pb,Cu and Cr) in soil of Niaowang tea in different tea plantations and ecological environments were analyzed,and single and comprehensive pollution indexes assessment were conducted with the background value of concentrations of heavy metals in soil for nuisanceless tea production.The results showed that the concentrations of heavy metals were different in different tea plantations and varied under different ecological environments.Positive correlation existed in Hg,As,Pb,Cu and Cr content obviously.However,the concentrations of these five heavy metals were relatively low,which could meet the soil quality standard for nuisanceless tea production.Both of the single and comprehensive pollution indexes were lower than 1.0.The soil quality of Niaowang tea production areas was quite good.
