| 摘 要： | 在不同日期直播的二季晚稻田间进行了0.01%芸苔素内酯不同施用处理的示范试验,结果表明:增产效果以0.01%芸苔素内酯每公顷300 mL在水稻分蘖期、破口初期、齐穗期各喷施1次为最佳,增产率达9.65%~16.56%;施用0.01%芸苔素内酯能缩短水稻抽穗持续时间,增强水稻抗御寒露风的能力,对水稻株高无明显影响,对水稻安全。

| Abstract: | The demonstrative test for the application of 0.01% Brassinolide solution was conducted in the field of double crop- ping late rice which was directly sown on various dates. The results showed that ： among different application methods, spraying 300 mL/hm2 0.01% Brassinolide once respectively at the tillering stage, initial rupturing stage, and full heading stage of rice could ob- tain the best yield - increasing effect, and its yield - increasing rate reached 9.65% ~ 16.56% as compared with the control （ no spraying）. The application of 0.01% Brassinolide could shorten the duration of rice heading, strengthen the resistance of rice to au- tumn low- temperature damage, and it had no obvious impact on rice plant height and was safe to rice. |
