It is a type of compound fertilizer. Synergistic compound fertilizer refers to a new type of compound fertilizer that adds cutting-edge fertilizer synergistic technology during the production process of traditional compound fertilizers. Compared with traditional compound fertilizers, it can significantly improve fertilizer utilization and enhance fertilizer efficiency, and is the development direction of high-efficiency and high-quality compound fertilizers. The slow-release synergist used in fertilizers includes humic acid and its salts, deionized water, a variety of additives and high-molecular polymer materials. It needs to be dissolved in water under high temperature, and then repeatedly refined into a solid mixture, and then the solid mixture is decomposed from large pieces into small pieces. In the process, it is repeatedly screened through a screen mechanism to keep the particles of uniform size, so that the effect is better when used.
