Abstract
The present invention discloses a high-activity seaweed compound fertilizer and a preparation method thereof and belongs to the technical field of compound fertilizer production. According to the technical scheme of the invention, the high-activity seaweed compound fertilizer is prepared by the following raw materials: urea, monoammonium phosphate, calcium magnesium phosphate, potassium sulfate, borax, ferrous sulfate, zinc sulfate, seaweed extract and seaweed powder. Compared with the prior art, the production device technology for existing urea-melt spray granulation compound fertilizers is fully utilized, wherein the uniformly mixed mixture of urea and seaweed extract is heated and melted in a urea melting tank. In this way, the carboxyl group and the hydroxyl group of the seaweed extract, and the carbonyl group of the urea, are subjected to sufficient condensation reaction to form a ureide-based alginate urea condensation product alginate ureide of a molecular network structure. Based on the sufficient combination reaction of the seaweed extract and urea molecules, the effect of the seaweed extract is improved and the slow-release effect of alginic acid to urea is also enhanced. Since the molecular weight is increased, the leaching of urea is reduced. The fertilizer efficiency is prolonged and the utilization rate of the fertilizer is improved.
