| Abstract: | According to historical data ,the effect of meterology factors on wheat powdery mildew was used to make a mathematics model which could be applied on super long term forecast model after a second examination. After sieving factors by pluratism regression method, dealing with it up to standard and analy zing equivosal relationship comprehensively, the ecology geography of wheat powdery mildew could be divided into three kinds. When the level of economic permitting demage was 3.1%, the prevention and cure quota was illness index number 9 in the middle and late March. |
