| Abstract: |
| Due to the scarcity of water resources and the serious overload of farmland production in Hebei Province, the essence and significance of rotation and fallow cropping in water\|shortage areas were discussed in this paper. The reformed principles of simplified cropping system characterized by rainfed farming and rotation with various crops and fallow were put forward. Considering with the characteristics of regional resources and the national demand, it was analyzed that the water\|suitable cropping system and technical strategies in water\|shortage areas of Hebei Province, including reducing wheat production to save irrigation water by transforming winter wheat\|summer corn double cropping into spring corn→winter wheat\|summer corn pattern, laying the field fallow during the winter and spring seasons; developing rainfed farming by covering with film and straw to harvest rain water and controlling soil water loss, exploring water saving irrigation technology; ensuring stable yields by selecting the water\|suitable crops, such as cotton, peanut, soybean, and rapeseed with infinite flowering habit, coordinating safe seedling formation technology; increasing economic benefits by replacing manpower production with mechanization and intelligence; achieving equivalent or effective substitution for high water consumption production by producing high\|quality agricultural products, entertainment and environmental products. |
