| 摘 要： | 探讨了Ｌａ，Ｃｅ，Ｎｄ，Ｐｒ４种单一稀土处理油菜种子，在不同程度Ｃｄ污染土壤上种植后，对油菜生长发育及吸Ｃｄ量的影响。结果表明，Ｃｅ抑制油菜吸收重金属Ｃｄ效果最佳，其次为Ｌａ，随土壤Ｃｄ污染程度加重，Ｎｄ，Ｐｒ对油菜吸收Ｃｄ也表现出一定的抑制效果，同时均不同程度地提高了干物质产量。影响Ｃｄ累积率降低幅度大小顺序为：Ｃｅ＞Ｎｄ＞Ｌａ＞Ｐｒ。

| Abstract: | The article studied the effect on the rape seeds which grew in different Cd polluted soil and the sorption of Cd influenced by La,Ce,Nd,and Pr.It showed that:Ce had the best inhibition effect on the sorption of Cd,the next was La,with the degree of Cd pollution increased,Nd and Pr also had the inhibition effect;and they increased the quantity of dry substance,the sequence of their reduce the accumulation of Cd in rapes was Ce>Nd>La>Pr. |
