specific Embodiment approach 1

[0010] Specific embodiment one: the composite bacterial agent that is used for cow dung composting to reduce ammonia release and nitrogen retention of the present embodiment consists of 12 parts of Serratia plymouth ( Serratia plymuthica ) preservation number ACCC No.01503 fermentation broth, 17 copies of Sphingomonas ( Sphingomonas trueperi ) preservation number ATCC No.12417 fermentation broth, 50 copies of Alcaligenes ( Alcaligenes sp. ) preservation number DSM No.2625 fermentation broth composition; the number of effective viable bacteria in the fermentation broth of the above three bacteria is 10 9 Individuals / mL or more.

[0011] The preparation method of this composite bacterial agent is as follows:

[0012] (1) Activation of strains: the preserved Serratia plymouth ( Serratia plymuthica ), Sphingomonas ( Sphingomonas trueperi ) and Alcaligenes ( Alcaligenes sp. ) were respectively inoculated into 150mL Erlenmeyer flasks containing 50mL of activation medium, th...

specific Embodiment approach 2

[0017] Specific embodiment two: the compound bacterial agent that is used for cow dung composting of the present embodiment to reduce ammonia release and nitrogen retention is made of 20 parts of Serratia plymouth ( Serratia plymuthica ) preservation number ACCC No.01503 fermentation broth, 25 copies of Sphingomonas ( Sphingomonas trueperi ) preservation number ATCC No.12417 fermentation broth, 63 copies of Alcaligenes ( Alcaligenes sp. ) preservation number DSM No.2625 fermentation broth composition; the number of effective viable bacteria in the fermentation broth of the above three bacteria is 10 9 Individuals / mL or more. The preparation method of the composite bacterial agent of this embodiment is the same as the first embodiment.

[0018] Inoculate the composite bacterial agent of this embodiment into compost mixed with cow dung and crushed corn stalks at a volume ratio of 2:1, and carry out compost fermentation for 60 days. NH 3 The peak of the release amount appear...

Abstract

The invention relates to a composite bacteria preparation for reducing ammonia release and preserving nitrogen in cow dung compost and belongs to the field of microorganisms. The invention aims at solving the problem that the existing biological preparation for reducing the volatile quantity of NH3 in the compost fermentation process through taking cow dungs as main raw materials and preserving the nitrogen is not invented. The composite bacteria preparation comprises the following components in part by weight: 12-20 parts of Serratiaplymuthica fermentation liquor with a collection number of ACCC No. 01503, 17-25 parts of Sphingomonastrueperi fermentation liquor with a collection number of ACCC No. 12417 and 50-63 parts of Alcaligenessp fermentation liquor with a collection number of DSM No. 2625. The composite bacteria preparation can greatly reduce the release amount of the NH3 in the composting process and effectively improve the content of nitrogen elements in a fertilizer.

Description

Technical field [0001] The invention belongs to the field of microorganisms, which involves a composite bacteria that uses cow dung to reduce ammonia release and nitrogen preservation. Background technique [0002] With the continuous development of my country's large -scale livestock and poultry breeding industry, the production of livestock and poultry feces is also increasing. If a large number of livestock and poultry feces are not harmless after generation, it will not only produce evil odor gases, but also cause serious environmental environment. Pollution will also breed mosquito and cause widespread spread of pathogenic bacteria, which will eventually threaten human health.Therefore, people must be harmless to livestock and poultry feces.At present, composting technology is the most commonly used and effective method for livestock and poultry feces.The compost technology relying on the broadly distributed bacteria, lines, fungi and other microorganisms widely distributed ...
