Abstract

The invention relates to an ammonia water method compound fertilizer preparation process, which comprises: (1) respectively crushing sweet potato residue, vinasse, edible fungus residue, monosodium glutamate residue and cake meal to obtain a material 1; 2) adding monoammonium phosphate, urea, ammonium chloride, attapulgite, EDTA chelated zinc, amino acid chelated iron, a biological agent, a mineral fertilizer, potassium chloride and the material 1 into a mixer, uniformly stirring, conveying into a grinding machine through a metering belt, and grinding to obtain a material 2; (3) adding a acidinto the material 2 fed into a granulator, and introducing ammonia gas for ammonia acid granulation to obtain a material 3 with proper particle specification; and (4) putting the material 3 into a drying machine, introducing hot air for heating, evaporating moisture to meet the moisture requirement of the product, cooling, screening, coating and packaging to obtain the finished product. The prepared compound fertilizer has the beneficial effects of being good in fertilizer compatibility, balanced in fertility, stable in property, not prone to deliquescence, capable of improving the physical and chemical properties of soil, not prone to causing soil hardening, free of pollution to the environment, lasting in fertilizer efficiency, high in fertilizer utilization rate and the like.

Description

technical field [0001] The invention belongs to the technical field of crop compound fertilizers, in particular to a preparation process of ammonia water method compound fertilizers. Background technique [0002] Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. Although most compound fertilizers must be multivariate, they still cannot completely replace organic fertilizers. Where conditions permit, the amount of decomposed organic fertilizers should be increased as much as possible. Combined application of compound fertilizer and organic fertilizer can improve fertilizer efficiency and nutrient utilization. The application of organic fertilizer not only improves the soil and activates the beneficial microorganisms in the soil, but more importantly, saves energy ...
