[0002] Blending can accurately mix fertilizer raw materials with multiple different components, so as to meet the needs of different crops for various nutrients at different growth stages, and avoid affecting crop growth and development due to insufficient single fertilizer ingredients or improper proportions. At the same time, organic fertilizers and inorganic fertilizers can be mixed. Organic fertilizers can improve soil structure, and inorganic fertilizers can quickly provide nutrients. After mixing, the two can give full play to their respective advantages and form a more nutritionally balanced mixed fertilizer.

[0003] In order to improve the utilization rate of fertilizer efficiency, prolong the duration of fertilizer efficiency, and avoid continuous topdressing, current mixed fertilizers are processed by coating. The production process is generally to form a coating on the surface of the fertilizer by using corresponding liquid or solid coating materials. Most existing coating devices can only use a single coating material to coat the fertilizer. Since mixed fertilizers contain multiple different types of fertilizers, the coating effect on the outside of some fertilizers is poor, and a composite coating of the two coating methods cannot be performed.
