How do earthworms survive the winter?

When earthworms pass the winter, the soil must be loose and fertile, the air permeability is good, and the temperature is controlled at 20-27 degrees. If the temperature is very low, a greenhouse can be built to heat up. Or use the existing equipment in the silkworm room or mulberry field covered with wheat straw to keep warm.

Second, how to raise earthworms?

1. The container had better be a wooden case. Now I feel that the effect of wooden box farming is better. Other utensils such as flowerpots, plastic boxes and so on can also be used, but there must be a small hole in the bottom that flows out.

2. Nutritional soil I currently use rotten and ripe cow dung and crude cardboard. In rural areas, it is best to use rotten crop straw, weeds, mule and horse dung that have turned into black soil. If it is not easy to find in the city, we can only collect some plant leaves and make them rot by long fermentation. pay attention to the soft nutrient soil.

3. Earthworm food is really varied. At present, I use rough cardboard and smear waste cooking oil on it, even the waste oil in the oil storage box of the kitchen range hood, as well as apple peel, carrot peel and so on. In addition, I was pleasantly surprised to find that the sediment of kitchen washing pot water is very good, and the sediment of washing and stir-frying pot water is even better through observation.
