| Abstract: | To unify the understanding and defination and to summarize the development status and direction of cold and arid agriculture, based on the realities of Gansu Province, natural features and distribution of cold and arid regions were determined, and the concept and connotation of cold and arid agriculture were discussedin this paper throught literature. Current agricultural production status in cold and arid regions was elucidated in terms of soil types and quality, planting structure and productivity, mechanization level, land management, andsocialized service level. Present problems in cold and arid agriculture were analyzed from the aspects of habitatfactor, soil factor, planting structure, input leveland technical support. It was proposed that future cold and arid agriculture should be developed under the mode of green coverage, watershed ecology and crop-livestock farming cyclewith technical means such as facilities, mechanization, intelligence and digitalization fully integrated, and key technologies and production strategies such as green coverage, directional soil cultivation, rapid improvement of soil organic matter, intelligent rain-harvesting agriculture, intelligent dry farming decision-making platform, intelligent nutrient product application, and optimized design of crop planting system studied particularly. |
