Combined type three-dimensional fermentation bed

Abstract

The invention discloses a combined type three-dimensional fermentation bed. According to the invention, each fermentation bed unit of the combined type three-dimensional fermentation bed comprises a walkway, a food taking area, an in-situ fermentation area and a low-position fermentation area, wherein each in-situ fermentation area adopts an overground type or semi-underground type design; paddingis laid in each in-situ fermentation area; a small amount of excrement and urine are subjected to in-situ fermentation degradation in each in-situ fermentation area; materials are turned over by utilizing the turning habit of pigs and mechanical equipment; each low-position fermentation area is a centralized discharge area; the size of each low-position fermentation area accounts for 1 / 4-1 / 2 of the area of a fermentation bed unit; by adoption of the semi-underground type design, the top parts of the low-position fermentation areas are flush with the in-situ fermentation areas; a manure leakage floor is laid at the top part of each low-position fermentation area; padding is laid at the bottom part of each low-position fermentation area; a self-propelled turning and throwing machine is erected in each low-position fermentation area in a longitudinal direction, and the padding and feces are turned over through machinery; the combined type three-dimensional fermentation bed provided by the invention retains the advantages of an in-situ fermentation bed in pathogen inhibition, immunity improvement and heat preservation in winter; and the centralized discharge area is in low-position fermentation, and the padding is mechanically turned over, so the fermentation efficiency is high, and the risk that a large amount of the feces is accumulated on the in-situ fermentation bed to cause bed blockage is avoided.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a composite three-dimensional fermentation bed. Background technique [0002] The in-situ microbial fermentation bed is an environmentally friendly breeding method. The pigs are in direct contact with the bedding, and the microorganisms in the bedding are used to degrade pig manure in situ. While achieving zero discharge of manure and no odor, it also has The following advantages: [0003] (1) The fermentation bed can inhibit pathogens in many ways, including: forming aerobic fermentation, constructing the growth environment of aerobic bacteria, and inhibiting the growth of swine disease anaerobic bacteria; the probiotics in the fermentation litter produce secondary metabolites directly Kill pathogenic bacteria; the temperature of mid-depth litter is kept constant at 40-50°C all year round to inhibit the growth of viruses. A small amount of pathogens in the litter does not reach...

AI Technical Summary

Problems solved by technology

[0009] The invention provides a composite three-dimensional fermentation bed, which solves the problem that during the use of the existing in-situ fermentation bed, especially when the amount of feces increases in the middle and late stages of pig fattening, the concentrated excretion area is accumulated due to a large amount of feces, and the humidity is relatively high. Dead bed problem caused by timely decomposition of feces
