The system includes a transfer breeding mechanism, a transition mechanism and a distributing and collecting mechanism. The breeding mechanism is composed of a two-row conveyor belt type breeding platform. A first conveyor belt rotates, a distributing mechanism distributes materials to the first conveyor belt, and treated biogas residues in which earthworms have been introduced are distributed as a biogas residue composting heap which is 50 cm high and having a width that occupies the width of the first conveyor belt completely on the first conveyor belt. After the whole conveyor belt is carpeted with the biogas residue heap, the first conveyor belt stops rotating. After the biogas residues are consumed by earthworms on the first conveyor belt and converted into wormcast, a second conveyor belt rotates； when the second conveyor belt starts rotating, a transition belt of the transition mechanism synchronously rotates, and an attractant spraying device on the distributing mechanism sprays attractants onto the transition belt. After the biogas residues are completely laid, the second conveyor belt and the transition mechanism stop rotating, and the earthworms enter a biogas residue heap system on the second conveyor belt under induction of the attractants.Drawings of Description 2 31 3 22 23 Fig. 1 13 14 11 12 13 15 Fig. 2 1
