preparation example Construction

[0063] The present invention also provides a preparation method of the microbial fertilizer described in the above technical solution, comprising: mixing dry powder of yeast fermentation waste liquid, inorganic water-soluble fertilizer and functional bacterial powder to obtain a water-soluble composite microbial fertilizer.

[0064] The present invention has no special limitation on the mixing operation, and the technical scheme of material mixing well known to those skilled in the art can be adopted. In the present invention, the mixing is preferably carried out under stirring conditions; the stirring time is preferably 20-30 minutes.

[0065] The preparation method provided by the invention is simple and easy to operate, and is convenient for industrialized production.

Embodiment 1

[0068] Water-soluble compound microbial fertilizer 1: 80% dried yeast fermentation waste liquid powder, 8% urea, 4.5% potassium dihydrogen phosphate, 6% potassium nitrate, 1.0% jelly-like Paenibacillus powder, 0.5% Bacillus subtilis powder The mass ratio of yeast fermentation waste liquid dry powder, inorganic water-soluble fertilizer and functional bacteria powder is 80:18.5:1.5.

[0069] In this example, the water-soluble compound microbial fertilizer 1 contains 53% organic matter, 24.1% NPK, 120 million effective bacteria / g, 0.2% miscellaneous bacteria, 0.55% moisture, and 5.7 pH.

[0070]The dried yeast fermentation waste liquid powder is from Angel Yeast Co., Ltd., and its mass content is 60% for fulvic acid, 13% for nitrogen, phosphorus and potassium, 20% for crude protein, and has a pH value of 6.0.

[0071] Preparation method of jelly-like Paenibacillus powder:

[0072] (1) Activation of strains: the Paenibacillus jelly-like strains were inoculated into the activation...

Embodiment 2

[0085] Water-soluble compound microbial fertilizer 2: 75.5% yeast fermentation waste liquid dry powder, 9% ammonium chloride, 9% monoammonium phosphate, 4.5% potassium dihydrogen phosphate, 1.0% jelly-like Paenibacillus powder, 1.0% licheniformis spores Bacillus bacteria powder; the mass ratio of yeast fermentation waste liquid dry powder, inorganic water-soluble fertilizer and functional bacteria powder is 75.5:22.5:2.

[0086] In this example, the water-soluble compound microbial fertilizer 2 contains 50% organic matter, 24.9% NPK, 0.7 billion / g effective bacteria content, 0.1% miscellaneous bacteria rate, 0.6% water content and a pH value of 5.7.

[0087] Bacillus licheniformis powder preparation method:

[0088] For the process flow and process parameters of the Bacillus licheniformis bacteria powder, refer to the "preparation method of the jelly-like Paenibacillus bacteria powder" in Example 1. The main difference between the two is that the composition of the culture med...

Abstract

The invention belongs to the technical field of microbial fertilizers, and particularly relates to a water-soluble compound microbial fertilizer and a preparation method thereof. The water-soluble compound microbial fertilizer provided by the invention comprises yeast fermentation waste liquid dry powder, inorganic water-soluble fertilizer and functional bacteria powder in a mass ratio of (68-85):(15-30): (0.3-3.5). According to the water-soluble compound microbial fertilizer provided by the invention, the water-soluble yeast fermentation waste liquid dry powder is used as an organic carrier,so that the defect that the traditional compound microbial fertilizer is not water-soluble is overcome, the application mode of the compound microbial organic fertilizer is expanded, meanwhile, the damage of the traditional organic fertilizer to crops is avoided, and by compounding the water-soluble yeast fermentation waste liquid dry powder with the functional bacterium powder and the inorganicwater-soluble fertilizer according to a certain proportion, the soil fertility can be effectively improved. Experimental results of the embodiment show that the content of the water-insoluble substances in the water-soluble compound microbial fertilizer provided by the invention is 0.08%-0.25%, and the requirement that the content of the water-insoluble substances in a general water-soluble fertilizer standard is less than or equal to 5% is met.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a water-soluble composite microbial fertilizer and a preparation method thereof. Background technique [0002] Compound microbial fertilizer is a kind of "ternary compound fertilizer" composed of organic fertilizer, inorganic fertilizer and functional bacteria, which embodies the comprehensive effect of "three effects in one", which can activate soil, improve soil fertility, inhibit disease and strengthen soil Microbial function, increase production and income, etc. [0003] At present, commonly used organic raw materials include straw, poultry manure, cake fertilizer, algae fertilizer, mushroom residue, industrial by-products, etc. However, the above-mentioned organic raw materials are often not completely decomposed, and after use, there will be burnt seedlings and dead seedlings, and the harmful bacteria carried by the organic raw materials will caus...
