How does rural marsh dreg breed earthworm?

How to use biogas residue to raise earthworms in rural areas? Earthworm culture with biogas dregs has the advantages of simple operation, low cost and high benefit.

Biogas residue treatment

After the biogas residue is removed, spread out and drain for 2 days, then mix well with 20% chopped straw, straw, leaves and domestic waste, and place it in the pit with a thickness of 20cm.

Earthworm stocking

Earthworms should be moved evenly and 65% humidity should be maintained.

Site management

The suitable living temperature of earthworms is 15 ℃-30 ℃, which can be cooled by sprinkling water in high temperature season, and can not be exposed to sun in outdoor culture, so shading facilities should be necessary. When the temperature is below 12 ℃, cover with straw to keep warm and maintain 65% humidity. Often pile up and raise earthworms separately.

Prevent injury

Prevent natural enemies, such as leeches, toads, snakes, rats, birds, ants, mites, etc., to avoid pesticides and industrial waste gases.

Culture environment

The breeding site is shaded by light, and the bed soil can not be turned at will in order to maintain a quiet environment.
