The project has developed a sulfur-based modified resin double-film controlled-release fertilizer process and industrialized production device. The controlled-release fertilizer produced has significantly improved controlled release performance compared with a single coating of sulfur or resin. The project team also blended controlled-release fertilizer and quick-acting fertilizer into controlled-release fertilizer for wheat according to different soil types, climatic conditions and nutrient requirements for the wheat growth cycle, and cumulatively promoted more than 300,000 mu of demonstrations in Shandong and Anhui. . The demonstration shows that the controlled-release fertilizer for wheat can increase production by 10% to 15% compared with other nutrient-conventional fertilizers.
