Deep analysis of fermentation bed culture technology

Interpretation of National Culture Policy

In the southeast coastal areas, traditional farms have been forcibly shut down for rectification due to serious pollution. Next, the state will gradually rectify the nationwide farms, and the farms with serious pollution and huge energy consumption will be closed for rectification. Fermentation bed culture will become the first and government-supported culture mode of ecological culture.

Detailed interpretation of fermentation bed Culture Model

The culture mode of fermentation bed can be divided into contact fermentation bed and partition fermentation bed, in which contact fermentation bed can be subdivided into aboveground contact fermentation bed and underground contact fermentation bed. Partition fermentation bed can be subdivided into vertical partition fermentation bed and separation partition fermentation bed.

Aboveground contact fermentation bed

The construction mode of the fermentation tank built from the ground up is called the above-ground contact fermentation bed, and the livestock and poultry are raised in direct contact with the fermentation mattress.

Aboveground fermentation bed

Partition of drinking water area of aboveground contact fermentation bed

The above-ground contact fermentation bed can be separated from the fermentation bed area in order to prevent the excessive humidity of the fermentation bed caused by leakage and sprinkling in the process of livestock and poultry drinking water.

Underground contact fermentation bed

The construction mode of the fermentation tank dug down from the ground is called the underground fermentation bed, and the livestock and poultry are raised in direct contact with the fermentation mattress.

Vertical partition fermentation bed

Livestock and poultry are raised in cage or net, not in direct contact with the fermentation mattress, and the breeding area is vertically distributed with the fermentation bed area.

Separated partition fermentation bed

Livestock and poultry are raised in cage or net, without direct contact with the fermentation mattress material, and the breeding area is not vertically distributed with the fermentation bed area. The two parts are separated by considering the site and operation factors.

Selection of cushion material

The selection of fermentation mattress materials is mainly sawdust, rice husk, sorghum husk, peanut shell, customers can match according to the local actual situation, in which sawdust is a necessary raw material, no matter how the cushion material is selected, sawdust needs to be added. However, straw and mushroom residue are not resistant to fermentation and easy to mildew, so it is not recommended to use a large number of them.

Maintenance of fermentation bed

The turning and throwing times of the fermentation bed mainly depend on the moisture of the 10cm material on its surface. When the surface moisture of the fermentation mattress is 30%-40%, it should be flipped once every three days, and if the moisture content exceeds 40%, it needs to be flipped once a day.

Introduction of bacteria in fermentation bed

First of all, from the functional analysis of a single strain

1.Saccharomyces cerevisiae

Compared with other strains, Saccharomyces cerevisiae has the advantages of large size and rapid reproduction, which can quickly decompose the organic matter in feces and urine and prevent it from oxidizing into harmful products such as amines.

2. Lactobacillus plantarum

Lactobacillus plantarum is an anaerobic strain, and hypoxia will occur in the local area during the operation of the fermentation bed. In this case, Lactobacillus plantarum can still play a role in decomposing feces and urine.

3. Bacillus subtilis

In the process of fecal growth and reproduction, Bacillus subtilis can form a variety of primary metabolites such as nucleic acids, amino acids and vitamins, which can be used by probiotics such as lactic acid and yeast to improve its reproductive activity and further improve the fermentation efficiency.

Analysis on the coordination function of bacteria in fermentation bed

For example, the strains of gold fermentation bed are composed of Lactobacillus plantarum, Saccharomyces cerevisiae and Bacillus subtilis, which can form a regional micro-ecological working system on the fermentation bed and coordinate and symbiosis with each other. at the same time, it can play a good inhibitory effect on spoilage bacteria.
