Methods and Key Technical Points for Raising Earthworms with Rural Biogas Residue

How do rural areas use biogas residue to raise earthworms? Raising earthworms with biogas residue is simple to operate, low in cost, and highly profitable, and mainly involves the following steps:
Biogas residue treatment
After the biogas residue is scooped out, spread it out to drain for 2 days, then mix it evenly with 20% chopped rice straw, wheat straw, leaves, and household waste, and place it flat in a pit at a thickness of 20-25 cm.
Introducing the earthworms
The earthworms should be moved in evenly, and a humidity of 65% should be maintained.
Site management
The suitable temperature for earthworm life is 15°C-30°C. During hot seasons, water can be sprinkled to cool things down. Outdoor breeding must not be exposed to the sun, and necessary shading facilities should be provided. When the temperature is below 12°C, cover with rice straw to keep warm and maintain 65% humidity. Separate the piles frequently, and raise large and small earthworms separately.
Preventing harm
Prevent natural enemies such as leeches, toads, snakes, rats, birds, ants, and mites, and avoid harm from pesticides and industrial waste gas.
Breeding environment
The breeding site should be shaded from light, and the bed soil must not be turned over at will, so as to maintain a quiet environment.
