Abstract
Water and fertilizer integration technology, as an important innovation in modern agriculture, combines irrigation and fertilization systems to regulate the supply of water and nutrients precisely, thereby improving agricultural production efficiency and resource utilization. This paper systematically elaborates on the fundamental principles of water and fertilizer integration technology, with a focus on analyzing its application effects under different crop and soil conditions, pathways for technological optimization and improvement, and a comprehensive assessment of its environmental and economic benefits. The research findings indicate that water and fertilizer integration technology offers significant advantages in water and fertilizer conservation, enhancing crop yield and quality, while also demonstrating great potential for efficient resource utilization and environmental protection. This paper further explores the technical, economic, and management challenges in promoting the application of this technology and, based on the latest research findings, outlines future development directions. The continuous innovation and promotion of water and fertilizer integration technology drive the green transformation and sustainable development of agriculture and present new opportunities and growth points for optimizing the global agricultural production system. This paper aims to provide theoretical references and practical guidance for researchers and agricultural practitioners, facilitating the in-depth application and promotion of water and fertilizer integration technology in modern agriculture.
