Abstract:

The research aims to explore the efficient and reasonable irrigation and fertilization mode of Astragalus membranaceus, to enhance the yield and quality of Astragalus membranaceus, and to improve the efficiency of resource utilization, helping the development of modern agriculture. The article summarized the effects of water-nitrogen coupling on soil nitrate nitrogen, outlined the research progress of water-nitrogen coupling on growth and development, photosynthetic characteristics, yield and quality of Astragalus membranaceus, and put forward the evaluation indexs of water-nitrogen coupling effect on Astragalus membranaceus and a comprehensive evaluation model. The results showed that water-nitrogen coupling was an effective measure to save water and nitrogen resources, reduce environmental pollution and realize high quality and high yield of Astragalus membranaceus. In-depth exploration of the water-nitrogen coupling mechanism of Astragalus membranaceus to realize precise irrigation and fertilization can provide theoretical basis and technical reference for guiding the water-nitrogen management, water-saving and high-yield and high-quality growth of Astragalus membranaceus.
