四种小麦新型化杀剂EK、EKH、ENa和ENH对70个小麦品种(系)用药观察表明,杀雄效果均达95％以上,符合化杀剂杀雄标准。但小麦经EK和EKH处理后,平均结实率达80％以上,显著优于ENa和ENH处理后的结实率。EK、EKH二药品间对植株高、穗下节间长度和结实率诸性状的影响均不显著,可应用于制种。并找出了两药品对植株高,穆下节间影响的相关曲线.可用于指导化杀制种和对喷药后的植株进行预测。
The observation of 70 new wheat varieties EK, EKH, ENa and ENH showed that the killing effect of all four wheat varieties reached more than 95%, which was in line with the killer killing standard. However, after EK and EKH treatment, the average seed set rate of wheat reached more than 80%, which was significantly better than that of ENa and ENH treatments. EK and EKH had no significant effect on plant height, internode length and seed setting rate of panicle, which could be applied to seed production. And found out the correlation curve of the two drugs on plant height, the impact of Mu under the internode.It can be used to guide the killing of species and forecast the plants after spraying.
