| 摘 要： | 从1998年开始,持续3年时间,在太原市晋源区重金属污染比较严重的农田进行了稀土抗大白菜重金属污染栽培研究。试验结果表明,经过稀土处理的大白菜,与对照相比,重金属含量显著下降,其中Hg含量下降94%,Cr含量下降10.47%～90.3%,Cd含量下降89.4%～98.08%,Pb含量下降15.19%～75.38%,As含量下降83.33%～100%。此外,经过处理的大白菜产量也比对照有较大幅度提高。

A Study on Rare Earth Culture of Anti-Heavy Metal Pollution of Brassica Chinesis |
| |
| Abstract: | The field culture experiment of anti heavy metal pollution on Brassica chinesis has been conducted for three years in heavy metal polluted field in the southern suburbs of Taiyuan.The seeds were treated with rare earth before sowing and then sowed in the mid autumn each year,collected them at the beginning of winter annually and analyzed them in the lab.Compared with the CK,contents of Hg,Cd,Cr,Pb and As are reduced following 94%,89.4%～98.08%,10.47%～90.3%,15.19%～75.38% and 83.33%～100% respectively. |
