The development of modern agricultural technology has made water and fertilizer integration technology an important way to improve the efficiency and sustainability of agricultural production.This paper discusses the mechanism of plant growth regulation based on integrated water and fertilizer technology.By building an environmental control model for plant growth,comprehensively considering the interaction between environmental factors and plant physiological reactions,and setting up experiments in the smart greenhouse,key parameters such as soil moisture,fertilizer concentration,and light intensity are monitored in real time,and the growth rate of crops is recorded.,yield and quality.Experimental results show that reasonable water and fertilizer management strategies can significantly promote crop root development,photosynthesis and nutrient absorption,and can significantly improve crop yield and nutrient use efficiency.In particular,customized water and fertilizer supply strategies for different growth stages of crops are of great significance in improving crop stress resistance and reducing water and fertilizer loss.This research not only provides theoretical basis and technical guidance for modern agricultural production practice,but also provides reference for further precision agriculture research and sustainable development policy formulation.
