| 摘 要： | 水稻不同生育期污染主茎单个叶片结果表明，１３７Ｃｓ向植株未污染部位的转移与污染叶的叶位有关，植株中的１３７Ｃｓ主要分布在茎叶中。受污染的水稻各部位１３７Ｃｓ积累量与污染量呈线性正相关，植株各未污染部位１３７Ｃｓ比活度大小顺序为叶＞茎＞根＞穗。

| Abstract: | The sigle leaf of rice stem was artificially contaminated with 137Cs at different growth stages to study its foliage adsorption and translocation.The results showed that the translocation rate of 137Cs to non-contaminated parts of the plant was related to the phyllotaxis of the contaminated leaf. Most of 137Cs was distributed in leaves and stems. There was a positive linear relationship between the content of 137Cs in non_contaminated part of the plant and the amount of 137Cs fortified. The 137Cs in non-contaminated parts of the rice plant was arranged as follows in an order of its activity: leaf> stem > root > ear. |
