Abstract

A comprehensive active microbe coated slow release compound fertilizer comprises following materials by weight: 20-25 parts of urea, 20-25 parts of monoammonium phosphate, 18-20 parts of potassium sulfate, 15-25 parts of sodium cellulosate of 80-100 mesh, 30-40 parts of chicken manure fermentation fertilizer, 15-25 parts of carbon powder, 10-20 parts of calcium superphosphate, 10-20 parts of diatomite, 5-15 parts of solid inocula, and 5-15 parts of environment sensitive type hydrogel. The comprehensive active microbe coated slow release compound fertilizer and preparation method thereof can overcome defects of the existing slow release compound fertilizer, can implement multiple slow releases and controlled releases via coated controlled release, adsorption slow release and bio-type slow release so that the crops can get necessary fertilizer and nutrients in the growth cycle, and grow normally in every development period.

Description

technical field [0001] The invention relates to the technical field of inorganic-organic compound fertilizers, in particular to a comprehensive active microbial-coated slow-release compound fertilizer and a preparation method thereof. Background technique [0002] In modern agricultural production, many new types of fertilizers have emerged, including compound fertilizers, organic fertilizers, biological fertilizers, organic-inorganic compound fertilizers, bio-organic fertilizers, organic-inorganic biological fertilizers, slow-release fertilizers, and controlled-release fertilizers. , Each has its own characteristics. The existing compound fertilizer has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, convenient storage and application, etc., and plays an important role in promoting high and stable crop yields. [0003] Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the f...
