The invention discloses an industrialized earthworm breeding method. By means of the technical measures of breeding base constructing, earthworm breeding bed constructing, breeding greenhouse building, breeding greenhouse drainage system establishing, breeding feed adding mode determining, spray system building, breeding bed humidity requirement achieving, greenhouse lighting system establishing and earthworm harvesting mode determining, technique limiting is conducted on key points of industrialized earthworm breeding, therefore, after the method is adopted, the breeding method, breeding feed, a breeding environment, breeding conditions and a harvesting method are all standardized, a uniform standard can be implemented, the earthworm breeding quality is guaranteed, differences among earthworms are reduced, an earthworm breeding technology can be implemented in a standardized quality index frame, the growth speed, the growth scale, the reproduction speed, the earthworm quality, internal indexes of earthworm bodies all can be standardized and unified, and industrialized and large-scale breeding of the earthworms can be achieved.
