The invention belongs to the technical field of
fermentation engineering, and relates to a method for cultivating
bacteria in an airing room and application thereof. A method for cultivating
bacteria in an airing hall comprises the following steps that S1, high-temperature Daqu waste grass and high-temperature large-area
powder are matched according to the
mass ratio of 5: 1 and laid on the ground of the airing hall, a waste grass
ground layer is formed, and the laying thickness of the waste grass
ground layer is 5-8 cm; s2, the surface of the waste grass
ground layer is covered with a heat preservation layer, and the temperature of the waste grass ground layer is kept at 40-45 DEG C for no less than 7 days; s3, removing the
thermal insulation layer, and laying the fermented grains with the temperature lower than 30 DEG C on the waste grass ground layer to form a
microbial colonization layer with the thickness of 15-20 cm; and S4, the waste grass ground layer is removed, an inorganic
salt solution with the
mass fraction of 0.1-0.3% is sprayed and supplemented to the ground of the airing hall, and liquid supplementing is continuously conducted for 14-21 days. According to the method, the activity of ground microorganisms is rapidly activated by utilizing residual nutrients of waste grass and inherent
flora, free
flora in the environment is adsorbed, proliferation is promoted,
straw resource utilization is achieved, and the cost of a bacterium culture cycle is reduced.
