Problems solved by technology

[0006] At present, the bio-organic fertilizers on the market mainly use livestock and poultry manure, peat, and decomposed coal as organic raw materials. Single livestock and poultry manure is difficult to carry out large-scale production due to its slow fermentation, heavy air pollution, and large-scale occu

Embodiment １

[0031] The preparation method of the slow-release compound microbial fertilizer comprises the steps of preparing a fertilizer core, preparing a coating material and coating.

[0032] The preparation steps of the fertilizer core are:

[0033] (1) Ferment the strains in the compound microbial agent separately to obtain the fermentation broth of each strain, and use one or more of beef extract peptone medium, potato medium, and LB medium for single-species fermentation. Then inoculate the fermentation broth of a single strain into 20 parts of polyacrylamide, 8 parts of ε-polylysine, 4 parts of ascorbic acid, 4 parts of EDTA, and the rest in the mixture of organic fillers according to the inoculation amount of 1%. Fermentation to obtain a mixed bacterial agent.

[0034] The compound microbial bacterial agent is yeast, Azotobacter torus, Bacillus licheniformis, Bacillus subtilis, photosynthetic bacteria, Bacillus sporogenes, Bacillus megaterium, and Bacillus colioids.

Abstract

The invention provides a sustained-release composite microbial fertilizer and a preparation method thereof. The fertilizer comprises a fertilizer core and an envelope wrapping the fertilizer core, wherein the fertilizer core contains polyacrylamide, epsilon-polylysine, ascorbic acid, EDTA (ethylene diamine tetraacetic acid), a composite microbial agent and the balance being organic filler. The fertilizer is stable and efficient, and can be easily absorbed and utilized by crops, and damage and pollution to soil can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a slow-release compound microbial fertilizer and a preparation method thereof. Background technique [0002] Slow-release fertilizer, also known as slow-acting fertilizer, is a new type of fertilizer developed in recent years. This type of fertilizer can replace part of the functions of organic fertilizers, reduce the loss of nutrients in fertilizers, improve fertilizer efficiency, and reduce soil pollution from fertilizers. [0003] Slow-release fertilizers mainly include coated fertilizers and low-solubility fertilizers. Coated fertilizer is to improve the function or performance of the fertilizer. The surface of its particles is coated with a layer of fertilizer with a microporous hydrophobic and insoluble film. The nutrient release rate is controlled by chemical or biological decomposition using the pore size of the coating. Although the coating structure ha...
