[0011] The following will describe the concentrated fermentation bed barn for pig raising according to the present application, and the described embodiment is only one breeding embodiment of the present application, not all embodiments.

[0012] Regarding the preparation of the bedding of the concentrated fermentation bed: the bedding can be made of various materials containing a lot of fibers such as rice straw, wheat straw, and corn straw according to the season; the moisture content is controlled below 60%; the materials are cut to a size and length of less than 5 cm by a machine; the fermentation bacteria can be Bacillus subtilis and EM diluted with water and sprinkled on the materials, or sprinkled while laying; the prepared materials are poured into the middle concentrated fermentation pool through the fermentation bed special channel, and laid to an average thickness of 1.5 m; the leaky mesh is left with a 1 m space for turning over the bedding between the leaky mesh and the fermentation materials.

[0013] Regarding the arrangement of pig raising: after the fermentation bed barn is prepared, piglets (7-50 kg) can be directly transferred, 1 piglet per square meter of the barn; the smaller the piglets, the less the excrement, at this time, the lower fermentation bed is in a semi-idle state, and the public pig, delivery room, and positioning column can collect the urine and excrement to be put into the piglet fermentation bed to participate in fermentation, and the amount of urine and excrement put in is less and less to 50 kg of piglets; without breeding piglets, 0.3-0.5 square meters per piglet, and 50 kg to grow 1 square meter per piglet.

[0014] Regarding the management of the concentrated fermentation bed: the fermentation bed bedding is turned over, and the main operation is to mix and exchange the bedding under the leaky mesh with the middle bedding; a small or medium-sized excavator is driven through the fermentation bed special channel, and the bedding in the middle of the fermentation bed can be turned over 360 degrees; after turning over, it is driven away from the special channel; the excavator is selected to be a lithium battery excavator to reduce the noise to the pigs.

[0015] Regarding the disinfection of the concentrated fermentation bed barn: disinfection is carried out according to the normal disinfection plan of the field area; the fermentation bed temperature can reach 60 degrees, the depth is 1.5 meters, and it is turned over once a week for contact, and the fermentation bed is covered with a waterproof film when the barn is cleaned.

[0016] Regarding the environmental control of the concentrated fermentation bed: in summer, the windows are opened for air convection, the temperature in the barn is 3 to 5 degrees lower than outside, and a water curtain can be added in the south; in winter, the windows are closed for heat preservation, and natural ventilation on the roof can ensure basic ventilation.

[0017] Regarding the replacement of the centralized fermentation bed litter: generally after the crop is harvested, the straw is recycled, the litter organic fertilizer is sold as the base fertilizer for farmland, and the straw fermentation time is about 6 months; in the repeated embodiment 1.

[0018] According to the centralized fermentation bed house using straw, it is suitable for pigs, chickens, ducks, livestock and poultry, and various changes and improvements under the premise of not departing from the spirit and scope of the present application are also included in the scope of the present application.

[0019] Compared with the prior art, the centralized fermentation bed house using straw has the advantages of simple and reasonable structure, low construction cost, low technical requirement, large operation margin, livestock and poultry manure falling from the manure leakage net structure to the centralized fermentation bed of the intermediate circular and square polygon, manure and straw and other materials being mixed, centralized fermentation being beneficial to the activity of fermentation bacteria and improving the composting efficiency, the special channel of the fermentation bed being capable of being operated by the middle and large-sized machines, the circular and square polygon centralized fermentation bed improving the working efficiency and making it possible for the mechanical harrowing, the transportation of the fermentation bed litter also being mechanized, the hot air generated in the fermentation process rising and being discharged through the top ventilation well of the house, a negative pressure being formed at the bottom of the house and the air being taken in through the window to form a convection, the circular and square polygon house body design being capable of well utilizing the convection and reducing the energy consumption.
