Method using tunnel to culture organic earthworms

Abstract

A method using a tunnel to culture organic earthworms comprises the following steps: S1, the tunnel is located in the west and faces the east, extends along the north-south direction, is good in ventilation, and has a length not less than 50 m, a width not less than 10 m, and a height not less than 3 m; S2, a good draining system in the tunnel is ensured and a standard waterway is built to ensure that accumulated water can be discharged in time and waterlogging is not induced, and necessary mechanical ventilation equipment is added to reduce the concentration of carbon dioxide in the tunnel and the content of pathogens in the air; S3, a culturing pool with a depth of 1-1.5 m is built in the tunnel, a 20-to-40-cm-high layer of earthworm culturing medium is laid on the bottom of the culturing pool, and water is added to adjust the humidity to keep the water content of the earthworm culturing medium between 50% and 55%; and S4, healthy and lively earthworms of good breeds are selected and are inoculated to the earthworm culturing medium at a density of 2-3 kg per cubic meter, and the earthworms are cultured according to routine breeding management methods.

Description

technical field [0001] The invention relates to the technical field of special farming, in particular to a method for cultivating organic earthworms by using tunnels. Background technique [0002] Earthworms are annelids that grow in the soil. They are rich in protein and can be used as medicine. At present, earthworms are generally cultivated in earthworm breeding boxes. When harvesting, earthworms and vermicompost need to be taken out together and then separated, thus seriously destroying the living environment of earthworms and affecting the hatching of earthworm cocoons. Many young earthworms and earthworm cocoons are difficult to separate, resulting in low earthworm output; and earthworms are often fed together from generation to generation, and reproduce in modern times, resulting in racial degradation, which is not conducive to the conservation and reproduction of earthworms. Contents of the invention [0003] The technical problem to be solved by the present inven...

At present, earthworms are generally cultivated in earthworm breeding boxes. When harvesting, earthworms and vermicompost need to be taken out together and then separated, thus seriously destroying the living environment of earthworms and affecting the hatching of earthworm cocoons. There are many young earthworms and earthworm cocoons, which are difficult to separate, resulting in low earthworm output; and earthworms are often fed together from generation to generation, and reproduce in modern times, resulting in racial degradation, which is not conducive to the conservation and reproduction of earthworms
