Abstract

The invention discloses a stable long-acting compound fertilizer which comprises the following components: monoammonium phosphate, urea, calcium superphosphate ammonium chloride, potassium chloride, sweet potato type citric acid residue, vinasse, edible fungus residue, a biological agent, a mineral fertilizer, a chelated boron-zinc fertilizer, monosodium glutamate residue and cake meal, and a preparation method of the compound fertilizer comprises the following steps: uniformly mixing and fermenting an organic fertilizer; sieving and blending the inorganic fertilizer, granulating amino acid, drying and sieving, and coating and packaging. 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 compound fertilizer for crops, in particular to a stable long-acting compound fertilizer and a preparation method thereof. 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, sa...
