| 摘 要： | 螺蛳等供试生物能很快地吸收水体中的＾１３７Ｃｓ，并随着时间的延长而不断增加，吸收过程可用直线方程来表达，螺蛳、喜旱莲子草和金鱼藻可以用来净化被＾１３７Ｃｓ的吸收较少，其中稗草和喜旱莲子草较高；由于Ｋ＾＋与Ｃｓ＾＋之间的拮抗作用，帮可用施钾肥方法减少作物以土壤中＾１３７Ｃｓ的吸收。

| Abstract: | s:Spiral shell and some other organisms could absorb quickly 137 Cs from the water bodies.The absorption amount of 137 Cs increased with the time and the process followed a linear equation.The tests showed that Spiral shell,Alligator Alternanthera and Hornwort could be used to purge the water bodies contaminated by cesium 137. 137 Cs was absorbed lowly by experimented terrigenous plant,but highly by Barnyardgrass and Alligator Alternanthera.Because of the antagonism potassium ion and 137 Cs,application of potassium fertilizer could decrease 137 Cs absorption of plants. |
