Problems solved by technology

Therefore, the high-concentration compound fertilizer has been developed at a high speed. However, while the low-concentration compound fertilizer is developing to the high-concentration compound fertilizer, the problem of fertilizer agglomeration is more serious. After the high-concentration compound fertilizer is agglomerated, the utilization of fertilizer rate greatly red

Abstract

The invention discloses a nitrogen-phosphorus-potassium high-concentration compound fertilizer and a preparation method thereof. The nitrogen-phosphorus-potassium high-concentration compound fertilizer is prepared from, by weight, urea, coal humic acid, potassium chloride, potassium sulfate, ammonium chloride, ammonium bicarbonate, calcium superphosphate, monoammonium phosphate, bentonite, calcium carbonate, kaolin, yellow humic acid, brown humic acid, amino acid, plant probiotics, an initiator and a polymerization catalyst, wherein the plant probiotics is nitrogen-fixing bacillus or bacillus licheniformis or bacillus subtilis. The compound fertilizer is high in nutrient content, extremely few in accessory component and good in physical characteristic, reasonable matching and scientific proportioning are adopted, the concentration of the fertilizer is increased, the components are increased, the hygroscopicity is improved, the fertilizer caking problem can be improved, the fertilizer utilization rate is increased, the soil fertility is enhanced, the quality of crops is improved, and the yield of the crops is increased; after the plant probiotics is added, the nitrogen utilization rate is increased by 20%-50%, the phosphorus utilization rate is increased by 15%-25%, and the amount of potassium absorbed by plants is increased by 1.5 times or above.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a compound fertilizer with high concentration of nitrogen, phosphorus and potassium and a preparation method thereof. Background technique [0002] With the rapid development of agriculture and the needs of the agricultural materials market, low-concentration compound fertilizers can no longer meet the needs of modern agricultural development. Farmers need various special compound fertilizers and high-concentration compound fertilizers for different crops. Therefore, the high-concentration compound fertilizer has been developed at a high speed. However, while the low-concentration compound fertilizer is developing to the high-concentration compound fertilizer, the problem of fertilizer agglomeration is more serious. After the high-concentration compound fertilizer is agglomerated, the utilization of fertilizer rate is greatly reduced. Moreover, most of the existin...
