Abstract: In order to study the fermentation and reuse of cattle manure bed, to solve the contradiction between cattle environmental pollution and industrial development, a fermentation experiment was carried out in some houses of the 300 large-scale dairy farms in Huanggang city, and the 1 200 large-scale beef cattle farms in Jingmen city of Hubei province. The mode and fermentation effect of the bed fermentation were investigated. The results showed that the fermentation of dairy cattle breeding bed should adopt ectopic fermentation, and the fermentation of beef cattle breeding bed should adopt the combination mode of in situ fermentation and ectopic fermentation, or adopt the ectopic fermentation mode. The strain should be combined with Bacillus licheniformis, Bacillus subtilis, yeast, lactic acid bacteria, and Thermosporium thermophila in a certain ratio. After the fermentation of the litter, the fertilizer efficiency increased, most of the heavy metals were degraded, and the total number of bacteria increased, while E. coli decreased significantly. The large-scale cattle breeding bed can be reused after fermentation and decomposing.

Key words: pad fermentation, scale cattle raising, fermentation effect, fermentation mode
