1. Potting method: prepare a flowerpot, add feed (three quarters of the height of the pot) into it, and then stock 100-200 earthworms in it. 2. Box-and-frame feeding method: prepare boxes, drill drainage holes and ventilation holes at the bottom and sides, pile up soil with a height of about 16cm, and stock 5000- 10000 earthworms in each box. 3. Pond culture method: Build a culture pond (2×10.2m) and put the decomposed mixed feed into the pond.

First, four methods of raising earthworms indoors

1, pot method

(1) Prepare containers, such as flower pots, plastic pots or discarded ceramics.

(2) Feed should be added to the pot, the amount of which is about three quarters of the height of the pot.

(3) Fill each pot with about 100-200.

(4) In order to ensure the proper humidity in the basin, cover the basin mouth with a layer of plastic film (pay attention to punching holes to ensure ventilation) and spray water frequently.

2. Box feeding method

(1) The specifications of the box are mainly 60cm? 30cm？ 20cm、60cm？ 40cm？ 20cm、60cm？ 50cm？ 20cm、60cm？ 20cm？ 30cm、60cm？ 40cm？ More than 30cm.

(2) Fill each case with about 5000- 10000.

(3) Drainage and ventilation holes (about 0.7- 1.2cm in diameter) need to be drilled at the bottom and side of the box, and the total area of the holes accounts for about 20-30% of the bottom or side of the box.

(4) Pile the soil into the box, with the height controlled at about 16cm.

3. Pond culture method

(1) Red bricks are used to build a feeding pond with a size of 2? 1? 0.2m, the bottom of the pool is leveled with cement, and the inner and outer walls need not be coated with cement.

(2) Put the decomposed mixed feed with water content of 60% into the pond.

(3) Stocking 1000-2000 earthworms in each pond.

4. Garbage feeding method

Garbage disposal: removing harmful metals, plastics, glass, stones and other impurities, then composting and fermenting, and finally putting the fermented garbage into the pool as feed.

Second, do you need to change the soil frequently to raise earthworms indoors?

Generally, it is not necessary to change the soil frequently when cultivating earthworms indoors, but the following matters should be noted when cultivating earthworms:

1, temperature

(1) The active temperature range of earthworm is 5-30℃, and the suitable active temperature range is 20-27℃.

(2) If the temperature is too high in summer, water it in time to cool it down. The temperature is too low in winter, so cover it with straw to keep warm.

2. Humidity

The suitable humidity is 40-60%. It should not be too dry or too wet.

3.ph value

The pH value should be 6-8, neither too high nor too low, because there are chemical sensory organs sensitive to acid and alkali on the surface of earthworm.

4. Breathability

Turn over the soil in time to ensure good air permeability and sufficient oxygen.
