| Abstract: |
| Based on sampling data from Zhongning county and Luhuatai horticultural farm of Yinchuan city in different dates,weather condition and its influence on epidemic of Colletotrichum gloeosporioides Penz were analyzed by using the method of principal components analysis and stepwise regression.The results showed that temperature and air humidity were key factors which impact on Colletotrichum gloeosporioides Penz epidemic.The second factor was wind and precipitation. The higher the temperature during fruits developing stage of medlar,the slighter the Colletotrichum gloeosporioides Penz occurred.However,the higher the air humidity during fruits developing stage of medlar,the heavier the Epidemic of Colletotrichum gloeosporioides Penz. |
