Embodiment 1

[0028] Example 1 Preparation of ternary compound bacterial agent

[0029] The pig fermentation bed ternary composite bacterial agent of the present invention is composed of composite bacterial agent I, composite bacterial agent II and composite bacterial agent III.

[0030] The compound inoculum I is a starter inoculum, which is composed of the following components in terms of weight percentage: 30% Trichoderma Corning, 30% Bacillus licheniformis, and Bacillus amyloliquefaciens 40%;

[0031] The compound inoculum II is a maintenance inoculum, which is composed of the following components according to weight percentage: Azotobacter sphaeroides 20%, Enterococcus faecalis 20%, Bacillus Laterosporus 15%, Bacillus amyloliquefaciens 25%, Bacillus subtilis 20%;

[0032] The compound inoculum III is an accumulation inoculum, which is composed of the following components according to weight percentage: Aspergillus oryzae 15%, Streptomyces 20%, Azotobacter sphaeroides 25%, Trichoderma corningii...

Embodiment 2

[0047] Example 2 Testing the effect of pig fermentation bed made by the ternary compound bacterial agent of the present invention

[0048] From July 2013 to October 2013, a pig farming experiment was carried out on the fermentation bed breeding technology of the product of the present invention. The litter is composed of sawdust and rice husk in a weight ratio of 1:1. According to the principle of the birth date and similar body weight, 60 hybrid pigs of the same breed and batch were selected and randomly divided into 2 groups with 30 pigs in each group. The test I group is the control group, a traditional cement fence; the test II group, the pig fermentation bed made of the ternary compound bacterial agent of the present invention is used for breeding.

[0049] Before entering the pig, use the compound microbial agent I (starting microbial agent), press 30 g / m 2 Add the compound bacterial agent I in the proportion of the dosage, and dissolve the compound bacterial agent I with 2L...

Embodiment 3

[0059] Example 3 Detecting the bed body effect of the ternary compound bacterial agent of the present invention in the production of fermented bed pigs

[0060] From October 2013 to January 2014, the application experiment of the product of the present invention on the bed surface substrate was carried out in a pig farm.

[0061] Test group 1: Commercially available foreign fermentation bed inoculants, containing Bacillus subtilis, amylase, and protease, with 10 viable bacteria 7 cfu / g, the additive dosage is 200g / m 3

[0062] Test Group 2: Sell domestic fermentation bed inoculants, containing lactic acid bacteria, spores, yeasts, the number of live bacteria is 10 9 cfu / g, additive dosage is 20g / m 2

[0063] Test group 3: The ternary compound inoculum of the present invention uses compound inoculum Ⅰ (starting inoculum) before entering pigs at a rate of 30 g / m 2 Add in the proportion of, 45 days after entering the pig, use the complex bacteria agent II (maintenance bacteria agent). Pr...

Abstract

The invention provides a ternary compound inoculant for a fermentation bed for pigs. The ternary compound inoculant is prepared from a compound inoculant I, a compound inoculant II and a compound inoculant III, wherein the compound inoculant I is a starting inoculant and consists of trichoderma koningii, bacillus licheniformis and bacillus amyloliquefaciens; the compound inoculant II is a maintaining inoculant and consists of azotobacter chroococcum, enterococcus faecalis, bacillus laterosporus, bacillus amyloliquefaciens and bacillus subtilis; the compound inoculant III is a stacking inoculant and consists of aspergillus oryzae, streptomycete, azotobacter chroococcum, trichoderma koningii and bacillus licheniformis. The ternary compound inoculant provided by the invention is an efficient conversion flora system with complementary function and complementary enzyme system; the compound inoculant I is fermented to produce heat before entering; the compound inoculant II is subjected to biological deodorization, bacteria inhibition and waste transformation in cultivation; the compound inoculant III is decayed at high temperature after being discharged; nutrients are preserved in situ. The ternary compound inoculant system is collaboratively progressive, a continuous circulating fermentation process for cultivation of the fermentation bed is achieved, and healthy and clean production of pigs is facilitated.

Description

Technical field [0001] The invention relates to a ternary composite microbial agent for a pig fermentation bed, which belongs to the technical field of microbial engineering. Background technique [0002] In recent years, with the rapid development of large-scale and intensive pig breeding in my country, the production efficiency has been greatly improved, and the traditional cement floor breeding model has also produced some disadvantages. First, the centralized discharge of pig manure requires a large area of ​​manure. Farm and flushing water wastes resources and labor, and causes serious pollution of the breeding environment and surrounding environment. [0003] Fermentation bed pig breeding technology is a new type of breeding method based on the control of livestock and poultry manure discharge and pollution. Its basic principle is to realize the in-situ degradation of livestock and poultry manure and urine, which greatly improves the breeding environment and is an environmenta...
