Method for improving aerobic stability of silage

The invention belongs to the technical field of silage preparation, and relates to a method for improving aerobic stability of silage. According to the method, a silage leavening agent is inoculated in a culture medium to be cultured under the anaerobic condition until the pH value of the system is 3.95-4.45 and the concentration ratio of lactic acid to acetic acid in the system is 9.69-13.25, the obtained culture solution is centrifuged, precipitates are collected and inoculated to silage raw materials to be fermented into the silage, and the aerobic stability of the silage can be improved. By controlling the acid yield of the silage inoculation culture and the content and proportion of lactic acid and acetic acid, the concentration ratio of lactic acid to acetic acid is in a range of 9.69-13.25, so that the growth of mould and saccharomycetes can be effectively inhibited in the silage preparation process, the aerobic stability of the silage is greatly improved, the storage time of the silage after cellar op
