Abstract:

Faced with the dual challenges of increasingly severe water scarcity and sustainable agricultural development, the importance of integrated water and fertilizer management as an efficient water-saving fertilization model is becoming increasingly prominent. To further analyze the problems and challenges encountered during the development of drip irrigation water and fertilizer integration technology, this study employed a systematic literature analysis, summarized the development history and current status of drip irrigation water and fertilizer integration technology, and synthesized its effects on soil physicochemical properties, crop yield, and water- and fertilizer-use efficiency, as well as research progress on drip fertigation equipment and system intelligent technologies. On this basis, the main existing problems are pointed out, such as imperfect irrigation scheduling, equipment clogging, and unreasonable design and layout of field pipelines. It is suggested that future efforts should focus on formulating scientific and rational irrigation schedules tailored to local conditions, optimizing field planning, establishing a more comprehensive index system for water and fertilizer management, and strengthening the intelligent development of technical equipment. The research aims to provide a theoretical basis for application and innovation of drip irrigation water and fertilizer integration technology and to promote agricultural productivity enhancement and sustainable use of water resources.
