More Information
Summary:The invention discloses a polyion sustained-release agent and a preparation method thereof, and belongs to the technical field of chemical fertilizer nutrient synergists. The polyion sustained-releaseagent is composed of 10-12 parts by weight of sesbania gum powder and 88-90 parts by weight of acidified palygorskite powder. The method comprise the following steps: through an auger type feeding machine, the sesbania gum powder and the acidified palygorskite powder are conveyed into a metering-stirring integrated frame type material-mixing machine according to the weight ratio, full mixing is performed for 65 seconds, the mixed material is discharged, the discharged material enters an automatic packaging machine through a belt conveyor, after packaging is performed, the polyion sustained-release agent is obtained, and the polyion sustained-release agent is stored in a dry and dark warehouse. The polyion sustained-release agent provided by the invention can reduce pollution to water andair by nitrogen, phosphoru
