为了研究不同类型土壤及种植蔬菜中重金属含量,选择两块试验田,种植不同品种蔬菜,分析了土壤及蔬菜中的重金属含量. 试验结果表明:土壤深度为0~80 cm时,两种类型土壤中的重金属Pb、Cu、Zn、Cd、Cr含量随着土壤深度的增加而减小;A区土壤Pb、Cu、Zn含量比B区高;种植的小青菜、小白菜中Pb、Cd、Cr含量A区大于B区;果实类蔬菜对重金属的累积量小于叶菜类.本研究成果可为土壤污染治理提供参考,为人体健康提供依据.
In order to study the content of heavy metals in different soil types and the vegetables planted,this pa-per chooses two plots to plant different varieties of vegetables,and analyzes the heavy metals content in the soil and vegetables.The results show that within the scope of 0 cm to 80 cm,the concentration of heavy metals Pb,Cu,Zn,Cd, Cr in two types of soil decreases with the soil depth.The content of heavy metals Pb,Cu,Zn in A area is higher than B area.The content of heavy metals Pb,Cd,Cr in small brassinca chinensis and small cabbages planted in A area is more than that in B area.Heavy metals accumulation amount in fruit vegetables is less than leaf vegetables.This study pro-vides reference for the soil pollution control and the basis for human health management.
