摘要: 【目的】研究新冬60号、新冬57号、新冬40号和新冬20号小麦白粉病危害程度和田间发生动态,为科学防控小麦白粉病提供理论依据。【方法】采用定期定点调查的方法,系统调查不同品种小麦白粉病发生情况。【结果】新冬60号、新冬57号、新冬40号小麦白粉病田间发生动态基本一致。新冬60号、新冬57号、新冬40号和新冬20号小麦白粉病病情指数最高分别为8.22、7.11、37.63和25.48。新冬60号和新冬57号小麦白粉病田间发生程度极显著轻于新冬40号和新冬20号,新冬40号小麦白粉病田间危害程度极显著重于新冬20号。【结论】新冬60号和新冬57号小麦白粉病田间危害程度极显著轻于新冬20号,可根据田间发病情况,合理减施农药。新冬40号小麦白粉病田间发生程度极显著重于新冬20号,应加强对小麦白粉病的预防。

Abstract: 【Objective】 The purpose of this research is to clarify the field dynamics of wheat powdery mildew in newly breed varieties in the hope of providing theoretical basis for scientific prevention and control of the disease.【Method】The occurrence of powdery mildew in different wheat varieties was systematically investigated by means of regular fixed-point investigation.【Result】The results showed that the field dynamics of wheat powdery mildew of Xindong No.60, Xindong No.57 and Xindong No.40 were basically the same. The highest disease index of wheat powdery mildew of Xindong No.60, Xindong No.57, Xindong No.40 and Xindong No.20 were 8.22, 7.11, 37.63 and 25.48, respectively. Repeated measurements showed that the occurrence degrees of wheat powdery mildew in Xindong No.60 and Xindong No.57 were significantly lower those in Xindong No.40 and Xindong No.20, and that in Xindong No.40 was significantly higher than that in Xindong No.20.【Conclusion】The occurrence degrees of wheat powdery mildew in Xxindong No.60 and Xindong No.57 were significantly lower than that in Xindong No.20 and the pesticide application could be reduced reasonably according to the occurrence of wheat powdery mildew in the field; The occurrence degree of wheat powdery mildew in Xindong No.40 was significantly higher than that in Xindong No.20, so the prevention of wheat powdery mildew should be strengthened. In this study, the field dynamics of wheat powdery mildew in Xindong No.60, Xindong No.57, Xindong No.40 and Xindong No.20 were clarified, which might provide theoretical basis for the relevant scientific prevention and control of the disease.
