摘　　要：分析了河南省信阳市冬小麦白粉病症状及季节流行进程,探讨了其发病规律与气象环境的关系,揭示了信阳市冬小麦区白粉病发病原因,应用相关分析和逐步回归方法,建立了小麦白粉病发生面积、开始发病时间、危害程度等级、危害持续时间等4种气象预报模型,并提出了对白粉病的综合防治对策。The symptoms and seasonal prevalence situation of powdery mildew on Xinyang winter wheat were elaborated, the retations between powdery mildew morbidity nile and the meteorological condition were discussed, the morbidity reason of powdery mildew in Xinyang winter wheat area was reviewed. The weather forecast models for the occurrence area, starting time, damage degree and damage duration of wheat powdery mildew were established using the stepwise regression method, and the control cotmtermeasures for powdery mildew were proposed.
