Abstract
Abstract Super absorbent polymer is a new type of functional polymer material that has been researched in recent decades. Due to its special structure and water-absorbing and water-retaining properties, it has a broad field of drought resistance, soil improvement and crop protection. It is a new type of soil conditioner and agricultural drought-resistant and water-saving materials. Combining it with fertilizers to prepare agricultural and forestry slow-release fertilizers with water-absorbing and water-retaining functions, it is very good in improving fertilizer utilization and saving water resources. This article summarizes the literature, expounds the research status, existing problems, and future research directions and hot spots of super absorbent resins.
