This paper studies a type of smart hydrogel responsive to pH changes, aiming to improve the water retention performance and fertilizer release efficiency of hydrogels. Multifunctional hydrogel materials are used, and by adjusting their chemical structure, they exhibit excellent responsiveness in environments with different pH values. This hydrogel not only has strong water absorption capacity but also can effectively control the slow release of fertilizers, thereby improving soil fertility and enhancing the effect of crop growth. Experimental results show that the prepared smart hydrogel has good pH responsiveness and long-term fertilizer release capacity, and has broad application potential in agricultural irrigation. This research provides new ideas for the development of smart hydrogels and lays a foundation for their application in the agricultural field.
