1975～1985年对小麦白粉病的发生和流行规律进行了系统研究,明确了农业栽培措施中的品种、播期、播量、行距和施肥及气象因素中的温度、湿度、降雨和光照等与白粉病的关系。根据八年的气象资料建立了四个统计预测公式,历史符合率较高,推广应用后取得较好的经济效益。 From 1975 to 1985, the occurrence and prevalence of wheat powdery mildew were systematically studied, and the varieties, sowing date, sowing date, fertilization and meteorological factors such as temperature, humidity, rainfall and light in agricultural cultivation were clarified Powdery mildew relationship. According to the eight-year meteorological data, four statistical prediction formulas have been established. The historical coincidence rate is high, and good economic benefits are obtained after the promotion and application.
