Abstract

The invention belongs to the field of liquid fertilizers, and particularly relates to a clear liquid type organic high nitrogen fertilizer comprising the raw materials in parts by weight: 11 to 16.5 parts of pure water, 26.5 to 27.5 parts of urea, 33.5 to 35.5 parts of ammonium nitrate, 0.5 to 0.65 part of organic acid, 0.5 to 0.65 part of 85% phosphoric acid, 22 to 24 parts of polymeric alcohol and 0.5 to 0.7 part of potassium hydroxide. The invention also discloses a preparation method of the high nitrogen fertilizer, wherein the preparation method comprises the following steps: (1) adding pure water into a reaction kettle, starting a stirrer, slowly adding the potassium hydroxide and the organic acid, and stirring until the potassium hydroxide and the organic acid react completely; (2) adding the urea and the polymeric alcohol into the reaction kettle, stirring, then adding the ammonium nitrate, and continuously stirring until no visible substance appears; (3) adding 85% phosphoric acid into the reaction kettle, turning on heating equipment of the reaction kettle, and stirring until the reaction is complete and the solution system is stable; and (4) standing the materials in the reaction kettle to normal temperature, filtering, and carrying out sampling inspection. The clear liquid type organic high nitrogen fertilizer is prepared in a chemical reaction and physical mixing mode, and the product is comprehensive in nutrient, stable in character and remarkable in fertilizer efficiency.

Description

technical field [0001] The invention belongs to the field of liquid fertilizers, and in particular relates to a clear liquid organic high-nitrogen fertilizer and a preparation method thereof. Background technique [0002] The research on liquid fertilizers started relatively late in my country, and the initial products of liquid fertilizers were mostly elemental fertilizers, such as ammonia water, urea ammonium nitrate liquid, nitric acid, and phosphoric acid. These fertilizers were mostly elemental fertilizers, and most of them were strong acid and strong alkaline fertilizers. It is extremely inconvenient. With the improvement of technology, compound liquid fertilizers with a large number of elements have appeared on the market, including clear liquid fertilizers, but there are also many problems that limit the production of this type of fertilizers by small and medium-sized enterprises, such as complex production processes, high requirements for raw material grades, and hig...
