| 摘 要： | 对进入水稻田中的氚水在连作晚稻阶段的迁移，输运动态过程的研究表明，滞留于早稻田中的氚水继续为晚稻摄取；与早稻情况一样，氚水中的氚仍以自由水氚和结合氚形式滞留在晚稻田各分室中，晚稻田水中和土肿的氚浓度均随时间单调地减少；晚稻地上部及根中的自由水氚及结合态氚浓度在采样期间也基本上随时间降低。

| Abstract: | The dynamic processes of movement and translocation of tritium water in the second paddy have been investigated. The results showed that the tritium water was residued from first paddy and was quickly absorbed by second rice.Similar to that in the first rice,tritium in the second rice and soil was either tritium of free water or bound tritium. The tritium concentrations in the second paddy water and soil were monotonously decreasing with time.The concentrations of free water tritium and bound tritium in the overground part and root of second rice were decreasing during sampling period. |
