摘要
通过对近年来我国小麦白粉病发生流行情况的分析，总结讨论了影响小麦白粉病流行的气温和降水量等气候因素，结果表明秋冬季及早春气温偏高、小麦生长后期气温偏低，对病害的流行有利；多雨尤其是黄淮海及其以北地区多雨，对病害的流行有利。反之则不利于病害的发生，流行程度将会减轻。
According to analysis on epidemiology of wheat powdery mildew in the recent years in China,the incidence and epidemics of the disease was highly influenced by climatic factor,such as temperature and precipitation,etc.,relatively highly temperature in fall winter and early spring,and relatively low temperature in the late season of wheat growth,and too much rainfall could help the spread of the disease,especially in the wheat growing areas of North China.
