| 摘 要： | 为了研究茶叶品质与土壤环境间的关系，弄清贵州茶区土壤重金属的污染状况，保障茶叶质量安全。选择贵州省云雾、都匀、湄潭3个主要产茶区，采集土壤样品进行重金属Cr、Cu、As、Cd、Zn的含量特征分析，以NY 5020—2001《无公害食品茶叶产地环境条件》中无公害茶园土壤环境质量标准为依据，进行单因子污染指数、污染负荷指数进行评价。结果表明：贵州茶区茶园土壤质量良好，云雾、都匀、湄潭3个产茶区PLIzone均小于1，污染负荷指数表现为湄潭茶区>云雾茶区>都匀茶区。3个产茶区土壤Cr、Cu、As、Cd含量均低于无公害茶园土壤限量值，只有湄潭茶区少部分样品Zn超标。3个茶区茶园土壤Cu和As之间具有极显著的负相关关系，Cd与Cr之间具有极显著的正相关关系，说明土壤Cd和Cr具有同源性。

| Abstract: | In order to identify pollution status of heavy metals in tea garden soil in Guizhou, to ascertain soil heavy metal pollution of tea garden in Guizhou, protect the quality and safety of tea. Soil samples were collected in Yunwu, Duyun and Meitan tea producing areas in Guizhou Province, and the contents of heavy metals Cr, Cu, As, Cd and Zn were analyzed. Single factor pollution index and pollution load index were evaluated as the based on the tea gardens soil environmental quality standards of NY 5020-2001 Green Food Tea Producing Environmental Conditions. The results showed good soil quality of tea gardens in Guizhou. The PLzone of Yunwu, Duyun, Meitan were less than 1, the order of pollution load index was Meitan〉Yunwu〉 Duyun. Contents of Cr, Cu, As, Cd in 3 tea producing areas soils were all below the limited values of pollution-free tea garden soil, but Zn exceeded the limited values in part of Meitan tea area. Cu and As had highly significant negative correlation in three tea gardens soil, Cd and Cr were highly significant between the positive correlation, which indicated that Cd and Cr were homology. |
