Paper Abstract

Through the geographic insemination test in installments on five phases of potato late blight in four areas of Mianning and Zhaojue with the altitude of 1,600m, 1,800m, 2,100m and 2,500m respectively, this paper researches the meteorological causes, leading factors and climatic indexes for potato late blight in mountain areas of southwest Sichuan in detail. Based on that, short-term section climatic inspection data of mountain areas, observation data from meteorological post and latest data from automatic weather station are extensively collected, organized and processed by extension, based on which the Spatial Distribution Model of climatic indexes for potato late blight in mountain areas of southwest Sichuan is established in association with the routine surface observation data, y=f(h,φ,l,β). With the geographic information data of 1:250000 and GIS technology, southwest Sichuan is divided into climatic liable region of potato blight, climatic secondary liable region and climatic non-liable region by factor setting and optimization method. Providing scientific basis for selection, distribution and prevention decision making for late blight resistant species of potato in southwest Sichuan, it has important value for production and application.
