应用盆栽试验和模拟小区试验相结合，研究增施磷肥和钾肥、土壤翻耕后对减少水稻植株（尤其是稻谷）中１３７Ｃｓ积累的效应。结果表明，增施钾肥可以使土壤中代换性１３７Ｃｓ活度明显降低，从而有效地减少水稻植株中１３７Ｃｓ的积累，施用量按每公顷９２２５ｋｇ硫酸钾表现最好。增施磷肥的作用表现不稳定，施用量较低时表现为水稻植株中１３７Ｃｓ积累量减少，但磷肥施用量增高时，表现为促进作物吸收１３７Ｃｓ。翻耕土壤能够有效地降低水稻植株中１３７Ｃｓ的积累。
Pot experiments and simulated plots were used to study the effects of increasing P and K fertilizers on reducing 137Cs accumulation in rice plants, especially in paddy soil. The results showed that potassium application could significantly reduce the substitutional 137Cs activity in soil, which could effectively reduce the accumulation of 137Cs in rice plants. The application rate was 9225 kg potassium sulfate per hectare. The effect of applying phosphate fertilizer was unstable. When the application rate was low, the amount of 137Cs accumulation in rice plants decreased, but when the amount of phosphate fertilizer was increased, the amount of 137Cs was increased. Plowing the soil can effectively reduce the accumulation of 137Cs in rice plants.
