| 摘 要： | 为研究噻苯隆对水稻农艺性状及产量的影响，采用不同浓度同时期和同浓度不同时期2种试验方案对水稻进行喷施，同时进行大田示范试验。结果表明：喷施噻苯隆后水稻的主要农艺性状明显优化，以3mg／L处理的效果较好；喷施不同浓度噻苯隆和在不同时期进行喷施，水稻产量均有不同程度增加，增产率最高达15．9％，以3mg／L的噻苯隆在水稻分蘖期、扬花期喷施效果最佳。对噻苯隆在水稻上的主要增产机理进行了研究。 |

| Abstract: | In order to study the effects of thidiazuron on agronomic traits and yield of flee, two experimental plans that spraying thidiazuron with different concentrations at the same period and spraying thidiazuron with the same concentration at different periods were designed, meanwhile the demonstration experiment in filed was conducted. The results showed that main agronomic traits of rice were obviously improved after spraying thidiazuron and the effect was the best when concentration of thidiazuron was 3 mg/L. When spraying thidiazuron with different concentrations and spraying thidiazuron at different periods, the yield of rice all increased in different degrees, the highest increasing rate reached 15.9%, and the effect was the best when spraying thidiazuron with concentration of 3 mg/L at tillering stage and blooming stage. The main increasing mechanism of thidiazuron applied in rice was studied. |
