摘要

The content of several elements in some vegetables of frait type was determined. The results show that the average content of Cu,Zn,Cr and Mn in this region are 15.4×10-6，40.89×10-6，2.31×10-6 and 60.48×10-6 respectively.The content of such elements in vegetables of fruit type is mainly affected by the vegetable category and the environment situation of siol.%测定了珠江三角洲几种果菜中Cu、Zn、Cr、Mn含量。结果表明，该地区几种果菜中Cu、Zn、Cr、Mn的平均含量是Cu 15.4×10-6,Zn 40.89×10-6，Cr 2.31×10-6，Mn 60.48×10-6。蔬菜中微量元素含量与蔬菜种类、元素对作物的必需性、土壤环境条件等有密切关系。
