Fermenting bed with microbial paddings

Abstract

The invention discloses a fermenting bed with microbial paddings. The fermenting bed provided by the invention comprises an upper layer and a lower layer. The upper layer has a thickness of 30-40 cm and comprises 30-70wt% of sawdust and 30-70wt% of rice husks; the upper layer is prepared by adding 5-10kg of rice bran, 50-200g of environment-friendly bacillus subtilis preparation into per cubic meter of the mixture of sawdust and rice husks, mixing and fermenting, wherein the moisture content is controlled at 40-50%. The lower layer has a thickness of 40-50 cm and comprises sawdust, rice husks, rice bran and environment-friendly bacillus subtilis preparation; and the moisture content is 20-30%. By using the fermenting bed provided by the invention, the pig manure degradation using a microbial preparation is guaranteed, so as to realize energy conservation and emission reduction. Since the paddings with different moisture contents are laid at different layers in the pit of the fermenting bed, the permeability management of the entire fermenting bed and the padding moisture content regulation are enhanced, the moisture content at the lower layer of the fermenting bed is reduced, the activity regulation of the microbial preparation viable count in the paddings is promoted, and the service lives of the paddings are prolonged, thereby obtaining a better sewage treatment effect.

Description

technical field [0001] The invention relates to a microbial bedding fermentation bed, in particular to a microbial bedding fermentation bed applied to tunnels in pig breeding pens. Background technique [0002] Japan, Taiwan and other countries and regions are widely popular in the pig breeding technology of biological bacteria agent fermentation bed, so that pigs grow on the fermentation bed, and the excrement and urine excreted are directly degraded by a large number of microorganisms in the fermentation bed, thereby reducing the generation of harmful gases in the farm. It also reduces the discharge of feces and urine, achieving the purpose of energy saving and emission reduction. However, since the pigs grow directly on the fermented bedding material, there are inherent disadvantages: one is that the pigs feed on the bedding material when they are hungry, and they ingest a large amount of indigestible substances such as sawdust or chaff, causing intestinal obstruction and...

Problems solved by technology

[0004] In the past, the microbial litter was evenly configured according to the same formula and moisture ratio, and then laid in the tunnel under the prefabricated slatted floor bed in the elevated prefabricated slatted floor bed to form a fermentation bed to degrade pig feces and urine, with a thickness of 60-80 cm. etc., there is no stratified configuration with different moisture ratios, so the air permeability of the entire fermentation mattress layer is not uniform; at the same time, due to the seepage of urine, the moisture content of the upper and lower layers of the litter is quite different, and the excess moisture affects the bottom litter Fermentation effect of environmental protection bacteria agent and effect of manure treatment
