在水稻土中添加钢渣和钙镁磷肥后,能够提高土壤外源镉污染条件下水稻的产量;在一定范围内随着钢渣或钙镁磷肥加入量的增加产量呈现增加的趋势,但进一步增加其用量时,产量呈现降低的趋势。两种改良剂配合施加时产量增加效果更明显。从取得最高产量的角度来讲,处理C14（即钢渣1.5 g/kg＋磷肥1.2 g/kg）为最佳用量;镉污染土壤上水稻植株不同部位镉的含量不一样,由大到小的次序为：根〉茎叶〉糙米;土壤中添加改良剂并没有改变水稻各部位镉的含量的次序,但降低了各部位镉的含量。

It improves rice production when slag mucks and FCMP are added to paddy soil under the cadmium soil condition;In a certain range with slag mucks or FCMP increase in the amount of output showed an increasing trend,However,further increase its usage,the trend of production has decreased.Two improver imposed when production increased with effect more obvious.The highest yield obtained from the point of view,dealing with C14（slag mucks 1.5 g/kg soil ＋ FCMP 1.2 g/kg soil） is the best dosage.The content of cadmium in rice different parts are different in cadmium-contaminated soil,order： root stems brown rice.Added conditioner in the soil and it did not change the location of the cadmium content in the order,but the lower part of the cadmium content.
