Example Embodiment

[0029] Example one

[0030] The preparation process of the microbial bobility in this embodiment includes the following steps:

[0031] 1) Preparation of composite microbial formulations. The composite microbial formulation used in this example is compounded from 10 kg of Bacillobacillus liquid, 20 kg of Youth bifidobacterium, 21kg long bifidobacterium liquid, 50 kg of black pneumacterial solution. The inventors have prepared four single bacteriobacteria fluids, first separately of the Bacillus bispococcus, Youth Bifidobacterium bacteria, the bifidobacterium strains, and the black pneumacterium, and then prepared into liquid seeds. The liquid is further accessed to carry out high density culture in a corresponding fermentation medium, resulting in four single bacteriobacterial liquid, and finally adding the four bacteria solutions to the proportion to prepare a composite microorganism formulation. The content of the tetrafi liquid is: the volume of Bacillus undergarment is ≥3.0 × ...

[0035] The preparation process of the microbial bobility in this embodiment includes the following steps:

[0036] 1) Preparation of composite microbial formulations. The composite microorganisms used in this example are compounded from 13 kg of Bacillobacillus liquid, 10 kg of Youth bifidobacterium liquid, 25 kg long bifidobacterium liquid, 43kg black spherot bacteria solution. The preparation process of the four single bacteria fluids in this embodiment is the same as the examples.

[0037] 2) Adjust the nutrient ratio of the biogas. Sugar honey 4kg, fish powder 4kg, phosphoric acid dihydrogen phosphate 3 kg and calcium phosphate 6kg, then molasses, fish powder, phosphate dihydrogen calcium, phosphate and calcium phosphate addition 950L biogas, stir The mixture was mixed and mixed. The main water quality indicators in the biogas solution were: COD1450 mg / L, ammonia nitrogen 550 mg / L, total phosphorus 130 mg / L, pH 8.0.

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...
