贵州省黄平县太子参基地土壤环境质量监测与评价

Monitor and Evaluation for Soil Environment Quality of Radix Pesudostellariae Base in Huangping County, Guizhou

对贵州省黄平县一碗水乡太子参基地土壤中的重金属Cd、As、Hg、Cu、Pb、Cr的含量进行测定,采用单因子污染指数法和综合污染指数法进行评价。结果表明,土壤中Cd、As、Hg、Cu、Pb、Cr含量都较低,单因子污染指数和多因子污染指数值均小于1.0,属于污染等级中的安全级,完全符合种植无公害中药材太子参的土壤条件。

The contents of heavy metals in the soil of Radix Pesudostellariae base, including Cd, As, Hg, Cu, Pb and Cr were determined and evaluated by using the indexes of single factor and multi-factor pollution. The results show that the contents of six heavy metals in the soil are relatively lower and the indexes of single factor and multi-factor pollution are below 1.0, which is completely suitable for Radix Pesudostellariae cultvation.
