| Abstract: | Mountain areas of South Ningxia with typical continental climate, is good for the Puccinia striif-romis West to spend summer. By systematic spot observation and general survey in the field for twelve years, it was found that germs of the P. striiformis West entered the areas in April to May. In normal years, the infected plants occured in the last ten days of May to the first ten day of June and the second and last ten day of June were active spread period of the germs. Therefore the key protection time was around June 25. Based on the ocurrence degrees over years and with the help of meteorological data, a fuzzy unified apraise and forecasting model was established. By back_test in past 11 years and forcast in 5 coming yeas, the model is with 93.8% in accuracy. A forecasting check table was also made for those tecnicians of forecast and agrotechnical workers in country_side. |
