Abstract: In order to effectively decrease the impact of the adverse property of “drought, waterlogging, concretion, leanness” in lime concretion black soil and frequent natural disasters of transitional climate in Huaibei area of Anhui province on wheat sustainable high yielding and production potential fully playing in this area. Since the “eleventh five-year plan” for national science and technology project of food production implementation, through the method of scientific research, verificating and demonstrating with many years and points and tracking analysis by establishing file at fixed fields, centering on regional soil characteristics, ecological conditions and wheat production status, from the aspects of improving lime concretion black soil fertility, selecting suitable wheat varieties, building high quality population, using resource efficiency, adopting scientific fertilization methods and the preventing disease and lodging, and established “one increase two change three prevent” super-high-yielding technological system of wheat yield 9750 kg/hm2 which was suitable for transitional climate and the characteristics of lime concretion black soil in Huaibei area. The results indicated that, the application of this comprehensive technology system could make the wheat yields in several hundreds mu of tackling fields in project counties of Taihe, Mengcheng, Guoyang were higher than 9750 kg/hm2, and also can create typical high yield example in the same year at multi-points which the wheat yield was higher than 11400 kg/hm2. The formation of this technical system which had been tested and verified through field production practice had great application significance and promotion values on increasing wheat yield in a large range in lime concretion black soil area of the south of Huanghuai Region.
