【摘要】 以 30～ 10 0mg·L-1的烯效唑对盛花期的水稻叶面进行喷酒 .结果表明 ,烯效唑延缓成熟期间旗叶的衰老 ,表现在叶绿素含量增加 ,光合速率增强 ,超氧化物歧化酶活性增高 ,丙二醛(MDA)积累减少 .提高了水稻的千粒重及结实率 ,增产达 8.3%～ 13.6 %.更多还原

【Abstract】 With S 3307 sprayed on rice leaves during ripening it is showed that the senescence of flag leaves was retarded which was reflected by chlorophyll content increasing, photosynthtic rate enhanceidy, activity of SOD promoting and MDA content decreasing. The number of grains per ear and the weight of 1000-gains were increased, which resulted in yield increased around 8.3-13.6%.更多还原
