研究了施用石灰、褐煤和钾肥等对减少１３７Ｃｓ在水稻植株中积累的影响。结果表明，施用相当于土壤阳离子代换量１／２０的钾盐，使水稻对１３７Ｃｓ的积累比对照组减少３２％以上，随时间变化，这种效应更加显著。在第２茬水稻试验中（１３７Ｃｓ污染后５７ｄ）施钾盐处理组水稻中１３７Ｃｓ的积累比对照组减少７６％以上，分析结果表明，施用钾盐后，土壤中代换性１３７Ｃｓ的含量比对照组低得多，差异十分显著。９９％以上的１３７Ｃｓ被土壤固定，难以被水稻吸收。本试验的两组施用量相比，低量组比高量组效果更好。
The effects of applying lime, lignite and potash on reducing the accumulation of 137Cs in rice plants were studied. The results showed that the application of potassium salt equivalent to 1/20 of the soil cation exchange rate reduced the accumulation of 137Cs in rice by more than 32% compared with the control group, and the effect was more significant with time. In the second stubble rice experiment (57 days after 137Cs pollution), the accumulation of 137Cs in rice decreased by 76% or more compared with the control group. The results showed that the content of substitution 137Cs in the soil was higher than that of the control The group is much lower, the difference is very significant. Over 99% of 137Cs are fixed in the soil and difficult to be absorbed by rice. The two groups compared to the amount of application, low-dose group than high-dose group better.
