Embodiment 1

[0030] The preparation process of microbial rooting agent comprises the following steps in the present embodiment:

[0031] 1) Preparation of composite microbial preparations. The compound microbial preparation used in this example is compounded by 10kg of Bacillus licheniformis bacterial fluid, 20kg of Bifidobacterium adolescentis bacterial fluid, 21kg of Bifidobacterium longum bacterial fluid, and 50kg of Eperococcus niger bacterial fluid. The inventor prepared four kinds of single-strain bacterial liquids by himself, first activated the preserved Bacillus licheniformis strains, Bifidobacterium adolescentis strains, Bifidobacterium longum strains, and Epicoccus niger strains respectively, and then prepared them into liquid seeds Then, they were respectively connected to the corresponding fermentation medium for high-density culture to obtain four kinds of single-strain bacterial liquids, and finally the four bacterial liquids were added together in proportion to obtain a com...

Embodiment 2

[0035] The preparation process of microbial rooting agent comprises the following steps in the present embodiment:

[0036] 1) Preparation of composite microbial preparations. The compound microorganism preparation used in the present embodiment is compounded by 13kg Bacillus licheniformis bacteria liquid, 10kg Bifidobacterium adolescentis bacteria liquid, 25kg Bifidobacterium longum bacteria liquid, 43kg Eperococcus niger bacteria liquid. The preparation process of the four single-strain bacterial liquids in this example is the same as that in Example 1.

[0037] 2) Adjust the nutrient ratio of biogas slurry. Weigh molasses 4kg, fishmeal 4kg, calcium dihydrogen phosphate 28kg, potassium dihydrogen phosphate 3kg and calcium phosphate 6kg, then add molasses, fishmeal, calcium dihydrogen phosphate, potassium dihydrogen phosphate and calcium phosphate into 950L biogas slurry, and then stir Mix well to obtain a mixture. The main water quality indicators in biogas slurry are: CO...

Embodiment 3

[0040] The preparation process of microbial rooting agent comprises the following steps in the present embodiment:

[0041] 1) Preparation of composite microbial preparations. The compound microbial preparation used in this example is compounded by 15kg of Bacillus licheniformis bacterial fluid, 15kg of Bifidobacterium adolescentis bacterial fluid, 15kg of Bifidobacterium longum bacterial fluid, and 30kg of Eperococcus niger bacterial fluid. The preparation process of the four single-strain bacterial liquids in this example is the same as that in Example 1.

[0042] 2) Adjust the nutrient ratio of biogas slurry. Weigh 5kg of molasses, 5kg of fish meal, 30kg of calcium dihydrogen phosphate, 4kg of potassium dihydrogen phosphate and 9kg of calcium phosphate, then add molasses, fish meal, calcium dihydrogen phosphate, potassium dihydrogen phosphate and calcium phosphate into 1000L biogas slurry, and then stir Mix well to obtain a mixture. The main water quality indicators in b...

Abstract

The invention discloses a microbial rooting agent prepared from biogas slurry and a preparation method thereof. The microbial rooting agent is prepared from compound microorganisms, molasses, fish meal, monocalcium phosphate, monopotassium phosphate, calcium phosphate and biogas slurry. The preparation method comprises the following steps: 1) preparing the compound microorganisms; 2) adding molasses, fish meal, monocalcium phosphate, monopotassium phosphate and calcium sulfate into the biogas slurry according to a preset proportion, and stirring and mixing to prepare a mixed solution; and (3) inoculating the compound microorganisms prepared in the step (1) into the mixed solution prepared in the step (2), and then carrying out facultative fermentation to prepare the microbial rooting agent. In the preparation process, the compound microorganisms can effectively degrade organic pollutants in the biogas slurry and convert the organic pollutants into small molecular substances, and a large number of physiologically active substances and thalli are generated. When the product is applied to crop planting, the microbial environment of crop rhizosphere can be improved, nutrients in soil are increased, and root development and plant growth of crops are promoted.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizers, in particular to a microbial rooting agent prepared from biogas slurry and a preparation method thereof. Background technique [0002] Biogas slurry is the product of aquaculture wastewater after anaerobic treatment, which is rich in ammonia, nitrogen, phosphorus, organic matter and high suspended matter, and also contains Ca 2+ , Mg 2+ It is a complex liquid waste. If the biogas slurry is not harmlessly treated, direct discharge will seriously pollute the environment. In addition, the pollutants in the biogas slurry are also a valuable resource. Microorganisms can degrade the pollutants in the biogas slurry, and convert macromolecular organic matter into small molecular substances that can be absorbed and utilized by crops. At the same time, during the growth and reproduction of microorganisms, they can A large number of physiologically active metabolites are produced, and thes...
