Application of Super Absorbent Polymer in the Research of Water-retaining and Slow-release Fertilizer

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