TO EXPLORE THE REGULATORY MECHANISM OF THE COUPLING EFFECT OF WATER AND FERTILIZER ON CROPS

ABSTRACT

Based on the research theme of exploring the regulatory mechanism of the coupling effect of water and fertilizer on crops, this paper analyzes the related concepts and theoretical basis of the coupling effect of water and fertilizer on crops, studies the factors affecting the coupling effect of water and fertilizer on crops, and puts forward optimal regulation strategies and methods. Firstly, the introduction introduces the research background and significance, clarifies the research purpose and content, and summarizes the research status at home and abroad. Then, in the relevant concepts and theoretical basis, the coupling effect of water and fertilizer was summarized, the characteristics of crop water and fertilizer and the relationship between water and fertilizer balance were analyzed, and the research progress in regulation mechanism was reviewed. In the part of factors affecting the coupling effect of water and fertilizer on crops, the influence and mechanism of the coupling effect of water and fertilizer on water resources management, fertilization strategy, soil properties and climate were discussed. Finally, according to the optimization control strategy and method, the corresponding application research direction is put forward in the aspects of efficient water-saving irrigation technology, precise fertilization technology, soil improvement technology and intelligent decision support system. In the conclusion, it summarizes the research, points out the innovation and shortcomings of the research, and looks forward to the direction of further research.
