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300mL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。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.
