Microbial fertilizer production system

The invention discloses a microbial fertilizer production system which comprises a supporting mechanism and further comprises a storage mechanism arranged on the supporting mechanism and used for storing microbial fertilizer. A mixing mechanism used for rotating the storage mechanism is arranged on the storage mechanism. A feeding mechanism used for feeding is arranged on the upper side of one end of the storage mechanism, and a humidifying mechanism used for humidifying fed materials is arranged on one side of the feeding mechanism. When raw materials are added into a mixing barrel through the feeding mechanism and the humidifying mechanism, liquid is sprayed to the raw materials for humidifying, then a first motor of the mixing mechanism drives a spiral blade on a rotating shaft to rotate, meanwhile, a gear is meshed with a gear ring to drive the mixing barrel to rotate, the raw materials in the mixing barrel are mixed through bidirectional rotation, so that the mixing efficiency of the raw materials is imp
