[0004] At present, the production of organic nitrogen fertilizers all adopts the disc granulation process, and the granulation rate is low, generally 30-35%, which makes the production capacity of the whole process low; the quality is poor, and the hardness of the particles cannot meet the requirements of mechanized sowing.
In addition, the disc granulation process needs to use adhesives, which reduces the water solubility of the product, which has a certain degree of influence on the fertilizer efficiency, and needs to increase the water content of the granulation. Process energy consumption is high

Abstract
The invention discloses long-acting sustained-release organic nitrogenous fertilizer and a manufacturing technology thereof. The long-acting sustained-release organic nitrogenous fertilizer comprises the following raw materials: 50-60 parts of gourmet powder waste residue solid raw materials or 30-35 parts of humic acid, 35-40 parts of urea, 8-12 parts of ammonium sulfate, 1 part of microelement, 0.7-0.8 part of long-acting sustained-release agent, 2 parts of liquid ammonia, and 2-4 parts of 92.5% of sulfuric acid. The manufacturing technology comprises the following steps: solid raw materials are metered, blended and sent into a granulating machine, and react with ammonia gas after being diluted by concentrated sulfuric acid; the produced ammonium sulfate slurry is sprayed into the granulating machine to be granulated, then is subjected to drying, screen classification, cooling, coating and packing, and is placed into a storage finally. According to the invention, the utilization ratio of the nitrogenous fertilizer is improved to 62.5%, and is improved one time higher than the utilization ratio of urea; the fertilizer has stronger controlled release capability and the capability of polymerizing absorbable nutrients in soil, not only can improve the output and quality of crops in long-term use, but also can improve soil structure to increase soil fertility, therefore, the fertilizer plays a significant role to the promotion of agricultural mechanization and the sharing of eco-food, and has prosperous prospect.
Description
technical field [0001] The invention relates to an organic nitrogen fertilizer and a production process thereof, in particular to a long-acting slow-release organic nitrogen fertilizer whose main materials are humic acid or waste residue produced by monosodium glutamate and urea and a production process thereof. Background technique [0002] According to statistics, the absorption rate of commonly used nitrogen fertilizers is only 20% to 30% of the amount used, which will not only cause a great waste of resources, but also the part that has not been absorbed will become a source of pollution. People usually use more nitrogen fertilizers to increase The practice of crop production has caused great pollution to the soil and the environment, and has had little effect on increasing the output value of crops, and has also reduced the quality of crops. Therefore, in order to increase agricultural output value, solve resources to increase fertilizer efficiency, improve fruit quality...
