| 摘 要： | 使用单一稀土—La、Ce、Nd、Pr对油菜种子进行浸种处理 ,以盆栽方式 ,明确了浸种处理后 ,油菜对Cr吸收、积累及生物产量的影响。结果表明 ,在不同程度Cr污染土壤上 ,4种单一稀土浸种处理均抑制了土壤中重金属Cr向油菜地上可食部分的吸收和转移 ,其抑制效果因土壤Cr污染程度不同而异。影响Cr累积率降低幅度大小均以Ce处理表现最佳 ,同时均不同程度地提高了油菜中干物质的积累

| Abstract: | The soak Pakchoi seeds were treated in different ways in La, Ce, Nd, Pr water, and then these seeds were planted in pots After soaking seeds, the green plants absorbed Cr and accumulated Cr obviously in a different way The production had distinct improvement The treatment showed the different level Cr in polluted soil, the four kinds of La, Ce, Nd, Pr treatments restrained heavy metal Cr which was absorbed and translated by the green plants The different reduced effect was due to the Cr polluted soil standard In reduced Cr accumulation, the Ce treatment was superior to others All of the treatments improved the dry weight in pakchoi, but the improvement had different levels |
