【Abstract】 It is well known that the influence of temperature and relative humidity isof considerable importance on the occurrence of wheat powdery mildew (Erysi-phe graminis DC.f.sp.tritici Marshal).Based on the principle of integrated ratemethodology as suggested by Sharpe.(1985),a simulated model was hither pro- posed to simulate the epidemic of wheat powdery mildew.In this paper we dis-cussed the biological and ecological significance of parameters of the model.Thesimulated and predicted values showed that the model can describe the epidemicof the wheat powdery mildew in field fairly well.更多还原
