The complete set of equipment for resin-coated slow- and controlled-release fertilizer uses polymer resin with very low water permeability as the coating material, and coats it evenly on the surface of the fertilizer particles to form a layer of resin with very low moisture dialysis. The water in the fertilizer enters the fertilizer particles through the resin film, and the nutrients are dissolved out of the film for crops to absorb. The fertilizer dissolution rate in the film is the effective release rate of fertilizer nutrients and achieves a slow and controlled release effect.
