山东寿光蔬菜对土壤中重金属富集的溯源规律及选择性种植

Traceable Rule of Soil Heavy Metal Enrichment in Vegetable and Their Selective Cultivation in Shouguang,Shandong

对山东寿光蔬菜基地土壤及蔬菜中的重金属含量进行了检测分析,研究了蔬菜中重金属富集的可溯源性。结果表明,几种主要重金属在土壤中和蔬菜中含量的高低顺序基本一致。据此提出了蔬菜的选择性种植方法,即在查明区域土壤重金属含量的情况下,按照蔬菜对重金属富集的差异性来选择要种植的蔬菜种类。

The contents of heavy metals in both vegetable - base soil and vegetable in Shouguang city of Shandong province were detected, and the traceability of soil heavy metal accumulation in vegetable was studied. The results indicated that the contents of several main heavy metals in soil and vegetable had basically consistent sequence. Accordingly, the selective cultivation of vegetable was proposed, namely after identifying the heavy metal content in regional soil, the different kinds of vegetable could be selectively planted according to the difference in their enrichment to soil heavy metals.
