【Abstract】 In this paper. the grey system clustering analysis theory and method is applied to make new attempts to predict and forecast the occurence degree of the crop diseases. The accuracy of the new method reaches 91. 67% by analysis and estimation of the twelve-year data collected from the 850 State-Farm. The results of the predicting and forecasting the occurence and epidemic degree of the Cerospa Sojina in 1992 and 1993 are accurate. This will provide a new research method for predicting and forecasting crop diseases.更多还原
