| 摘 要： | 对移栽期秧苗施用不同剂量的丁草胺，测定处理后不同时期秧苗根系还原强度，叶片的C／N。结果表明：施药后，前期（14d)秧苗根系还原强度比对照低，而后期（21d)比对照高，整个试验阶段的叶片C／N下降， 说明丁草胺对水稻的生理代谢有影响，所以对有害生物的防治应采用综合防治措施。

| Abstract: | Different doses of butachtor to rice seedlings that are in thansplant period are applied to examine in various stages after treatment the roots' ability to restore.It is shown that after the treatment the contrast of roots' ability to restore is not so sharp in the earlier stage (14d) as in the later stage(21d). The ratio of C/N of the blades is on the decline in the whole experiment. |
