| 摘 要： | 通过对夏大豆进行全程化控试验,结果表明:大豆上喷施多效唑及望立亭进行化控,能使大豆株高显著降低,七个处理中有三个处理对植株抗倒能力均有所增强;喷施多效唑化控对大豆主茎节数、结荚高度、茎粗、有效分枝影响均不显著。喷施多效唑化控,对产量影响不显著,但少量多次喷施有增产趋势,一次喷施量大会使大豆倒伏现象有增加趋势,使产量有所下降。

| Abstract: | The investigation of chemical control during different growing stages for summer soybean showed that spraying MET and TM reduced plant height significantly. Three out of seven treatments showed greater effect in resisting lodging. Spraying MET had no effect on soybean node number, pod-setting height, stem thickness, productive branch and yield as well. However, repeated spraying with a small amount of MET was beneficial for yield gain. Spraying an exessive amount of MET in one time increased the risk of lodging, and thus reduced soybean yield. |
