采用微波消解-FAAS测定了皖南休宁县茶园不同深度土壤中的矿质元素Cu、Cd、Mn、Zn、Fe、Pb的含量,分析了不同深度土壤中矿质元素的分布特征,结果表明,皖南土壤中矿质元素Cu、Cd、Mn、Zn、Pb 5元素含量随土壤深度呈递减趋势,土壤表层的矿质元素(Cu、Cd、Mn、Zn、Pb)含量高于深层的,这与施肥有关,土壤中的Fe、Zn、Mn元素含量较丰富,重金属Cu、Cd、Pb元素含量较低,表明皖南茶园生态环境良好,未受污染。
The content of mineral elements Cu, Cd, Mn, Zn, Fe and Pb in different depths of tea plantation in Xiuning County of Southern Anhui Province was determined by microwave digestion-FAASAS. The distribution characteristics of mineral elements in soils with different depths were analyzed. The contents of Cu, Cd, Mn, Zn and Pb in mineral elements showed a decreasing trend with the depth of soil, and the content of mineral elements (Cu, Cd, Mn, Zn, Pb) in the soil surface was higher than that in the deep soil, Fe, Zn and Mn were abundant, and the contents of heavy metals Cu, Cd and Pb were low, indicating that the ecological environment of Wannan tea garden is good and unpolluted.
