摘要：

对种植三七后土壤中的几种重金属元素含量进行了检测,以了解三七不同轮作年限土壤中重金属元素的存在情况,从而为三七的再次种植提供参考依据。在三七产区选择一年生、三年生、五年生、七年生三七栽培土壤,采用火焰原子吸收法分别对其中的铜、锌、铅、铬、镍5种重金属元素进行检测分析。结果表明,土壤中的这几种重金属元素含量都符合国家土壤标准和三七GAP栽培标准,并且不同轮作年限土壤中的铜、锌、铅、铬、镍含量不呈现规律性变化。

摘要：

The content of several kinds of heavy metal elements in the soil after planting Panax notoginseng was detected and the residual situations of heavy metal elements in the soil with different crop rotation years of P. notoginseng were understood, so as to provide reference basis for planting P. notoginseng in the future. The soil cultivated with the first, third, fifth and seventh planting year of P. notoginseng were collected from the production areas of P. notoginseng. The content of Cu, Zn, Pb, Cr and Ni in the soil was detected by using flame atomic absorption method. The results showed that the content of these kinds of heavy metals in the soil was accordant with national soil standards and GAP cultivation standards of P. notoginseng. And the content of Cu, Zn, Pb, Cr and Ni in the soil with different crop rotation years didn′t show regular changes.
