RESEARCH ON STRATEGIES FOR IMPROVING CROP WATER USE EFFICIENCY

ABSTRACT

This paper systematically discussed the theoretical basis, technical strategy, environmental and economic effects of improving crop water use efficiency, and analyzed the practical application of the strategy through a case study. Firstly, the paper defined the concept of WUE, analyzed many factors affecting WUE, including climatic conditions, soil types, crop characteristics, etc., and discussed the physiological mechanism of WUE and its relationship with crop production. In terms of technical strategies, this paper puts forward irrigation management optimization, crop planting model innovation, soil management improvement and agronomic measures integrated application strategies. The optimization of irrigation management discusses in detail the scientific establishment of irrigation system, the precise application of irrigation technology and the water-saving transformation of irrigation system. The innovation of crop planting pattern focuses on the optimization of crop layout and rotation system, intercropping and mixed cropping technology, and crop planting density. The soil Management Improvement section emphasizes the importance of soil structure and water retention, soil water monitoring and assessment, and soil improvement and fertilizer cultivation. The comprehensive application of agronomic measures covers the rational use of crop growth regulators, agricultural mechanization and automation, and integrated pest control. In the environmental and economic effects analysis section, this paper evaluates the impact of improving water use efficiency on sustainable water resources management and agricultural economic efficiency.
