摘要
选取与双晚白叶枯病流行程度关系密切的４个气候因子作为预测因子，应用加权列联表分析法，建立了双晚白叶枯病中期预报数学模型，回报历史符合率达１００％，对１９９２～１９９７年６年预测完全准确。
By means of method of weight contingency table,the four meteorological factors were selected,which have close relation with epidemic of bacterial leaf blight of late rice in a doubling-cropping,the mid-term forecast model was set up for bacterial leaf blight of late rice in double-cropping paddy fields.The percentage of according with historical data was 100%.The results of forecasting were accurate in six years from 1992 to 1996.
