Nano-scale microbial fertilizer and preparation method thereof

Abstract

The invention discloses a nano-scale microbial fertilizer and a preparation method thereof, wherein the nano-scale microbial fertilizer is prepared from fermented soybean cake, nano-scale natto powder, monoammonium phosphate, potassium chloride, ammonium chloride, urea, water-soluble nanometer silica, anionic polyacrylamide, borax, an organic material composting agent, a bioremediation bacterial agent, a Bacillus subtilis microbial agent, a high-activity Bacillus mucilaginosus agent, a Bacillus licheniformis agent, and a photosynthetic bacterial agent, and the special novel nano-scale microbial composite fertilizer for the blended cemented coated controlled release crops is produced by using the three-section granulation process; and the obtained nano-scale microbial fertilizer contains the organic matters, the inorganic matters and the microbial components, such that the nutrients of the fertilizer are completely provided and absorb, and the release rate is basically consistent with the fertilizer required by the crop breeding stage.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a nanoscale microbial fertilizer and a preparation method thereof, belonging to the field of microbial fertilizers. Background technique [0002] Fertilizer is a strategic material to ensure national food security, and it is the material basis for maintaining and improving soil fertility and realizing sustainable agricultural development. Fertilizers can be divided into organic fertilizers, inorganic fertilizers, and biological fertilizers according to their ingredients. Organic fertilizers contain low nutrient concentrations. After being applied to the soil, they must be decomposed and rotted by microorganisms to release nutrients. The nutrient release is slow, so they are suitable as base fertilizers and not topdressing fertilizers. Inorganic fertilizers contain relatively simple ingredients and high nutrient content. Most of them are easily soluble in water and have fast fertilizer e...

Problems solved by technology

At present, the coated slow-release and controlled-release fertilizers developed at home and abroad can only make the crops absorb nutrients better, but they are expensive. Therefore, people continue to study new solutions for bio-organic fertilizers and seek new products that improve crop yield and quality.
