Abstract

The invention discloses a high-tower humic acid type compound fertilizer. The high-tower humic acid type compound fertilizer comprises a basic fertilizer and a coating liquid coating the basic fertilizer, wherein the basic fertilizer comprises humic acid, improved pond sludge, ammonium phosphorus nitrate, monoammonium phosphate, potassium dihydrogen phosphate, potassium chloride and zinc chloride, and the coating liquid comprises a microbial liquid, alginic acid and polyethylene glycol. According to the invention, the basic fertilizer is coated with the coating liquid, so that direct contact between the basic fertilizer and soil and crop root systems can be avoided, water is gradually dissolved in the coating, the fertilizer particles in the coating are gradually released, diffused to a soil solution and continuously absorbed and utilized by crops, the leaching loss of basic fertilizer nutrients, the volatilization loss of ammonia, the fixation of phosphorus and the like are reduced, and the fertilizer utilization rate is improved. The invention also provides a preparation method of the high-tower humic acid type compound fertilizer.

Description

technical field [0001] The invention relates to the technical field of high-tower chemical fertilizers, in particular to a high-tower humic acid compound fertilizer and a preparation method thereof. Background technique [0002] High-tower compound fertilizer, the full name of high-tower granulation compound fertilizer, is one of the new technologies in my country's compound fertilizer production process. It is a method for preparing fertilizer by melt granulation. In the high tower, the compound fertilizer particles are produced. This kind of fertilizer has the characteristics of uniform and smooth particles, microporous, not easy to agglomerate, and uniform nutrient particle size. In terms of appearance, internal quality and increase of crop yield, it is far better than ordinary compound fertilizers sold in the market. The compound fertilizers sold on the market are generally granulated by simple rolling layer sedimentation. This kind of material distribution is due to the...
