Abstract

A method for preparing a high-tower nitro type seaweed composite fertilizer is disclosed. The method includes S1) chopping dry seaweed into small segments; S2) putting water into a digestion tank, stirring, adding potassium carbonate and then degrading the small seaweed segments; S3) sealing the digestion tank for digestion and degradation to obtain a liquid mixture, and performing centrifugationwhen the temperature of the liquid mixture in the tank decreases to 60 DEG C to obtain a centrifugate; S4) adding potassium humate into the centrifugate; S5) concentrating the centrifugate; S6) spray-drying the centrifugate to obtain a seaweed extract; S7) adding monoammonium phosphate, ammonium sulfate, potassium sulfate, potassium chloride and the seaweed extract to a high-tower ammonium nitratetank containing an ammonium nitrate solution, then mixing and grinding the materials, feeding the mixture to a high-tower granulator for granulation, and then performing sieving, cooling and coatingto obtain the composite fertilizer. The composite fertilizer produced by the method has more seaweed active substances, can achieve root promoting, seedling strengthening and shoot strengthening, andhas better flower and fruit protecting and stress resistance effects.
