Problems solved by technology

However, due to insufficient understanding of the mechanism of the composting process and the rationality of the inoculant manufacturing and application technology, the results of its use vary widely. The main problems are: ① Some inoculum one-sidedly focus on the effect of temperature rise, and use mesophilic microorganisms that decompose easily decomposable substances as the composting process. As a result, it does not have the ability to decompose the key component lignocellulose, and it disappears rapidly during the high temperature period, which does not play the desired role
As a result, it is often difficult to ensure that these bacteria can survive, and it is even more difficult to expect their stable effects

Embodiment 2

[0124] Embodiment 2, take the edible fungus chaff as main raw material composting composting

[0125] 1. High temperature composting

[0126] Compost raw materials: mixed with fungal chaff, urea, calcium carbonate and water; the mass ratio of fungal chaff, urea and calcium carbonate is 98:1:0.1, and the mass fraction of water is 56%. Wherein, the fungus chaff is the waste culture substrate left after the fungus production in Sanchakou Village, Sanchakou Town, Dongning County, Heilongjiang Province (it can also be the chaff of mushrooms, oyster mushrooms, Agaricus bisporus, Flammulina velutipes, Pleurotus eryngii, etc. ), obtained by removing the plastic skin and crushing into natural particles.

[0127] Mix the bacterial agent prepared in Example 1 and the compost raw material according to the mass ratio of 0.2:100, and make a pile with a width of 3m, a height of 1.3m, and a length of 20m. During the stacking process, the temperature of the stack body is regularly monitored ...

Embodiment 3

[0158] Embodiment 3, composting with livestock and poultry manure as main raw material

Abstract

The invention discloses a compost inoculant and applications thereof. The active ingredients of the composting inoculant provided by the invention include clostridium thermocellum, geobacillus stearothermophilus, Taiwan false xanthomonas, brevibacillus agri and bacillus licheniformis in a CFU (colony-forming unit) ratio of (3-5):(1-2):(1-2):(1-2):(1-2). Strains in the inoculant provided by the invention can grow in a symbiosis state well, and under the conditions of microaerobic co-culturing, lignocelluloses can be regularly proliferated and effectively decomposed in proportion. The inoculant is simple in manufacturing process due to co-culturing, stable in decomposition function, and long in quality ensured period. Experiments show that when the inoculant is adopted for fermenting composts, large gas feeding is not required, the energy is saved, and the nitrogen loss is reduced; composts can be thoroughly decomposed in advance, thereby improving the quality of fertilizers.

Description

technical field [0001] The invention relates to a composting bacterial agent and its application, in particular to a high-temperature composting rotting-promoting bacterial compound bacterial agent and its application. Background technique [0002] Composting is an important link in the decomposition of organic matter in nature and the promotion of element circulation. With the increase of production intensification and the expansion of urban scale, the concentration of waste is becoming more and more serious. Composting technology is to treat organic waste and reduce environmental pressure. And an important way to make organic fertilizer. [0003] The composting process is a process in which all decomposable organic matter is decomposed into a safe state under the action of microorganisms, and some elements are mineralized to become plant nutrients. The process can be divided into: sugar, starch, fat, protein and other easily decomposable substances decompose to generate h...
