Culture methods of Red Earthworm

Red earthworms are relatively small, with a general body length of 50 to 70 mm and a diameter of 3 to 6 mm, up to 90 mm and 150 mm in diameter. the body color is purple and red, and the depth changes with feed, water and light. it has the advantages of thick body cavity, more meat, long life, strong adaptability, easy feeding, high nutritional value and so on. Let's take a look at the breeding methods of red earthworms.

Breeding grounds of red earthworms

Red earthworms should generally choose places close to water sources and more convenient for the operation of animal manure, such as village gaps, forests, hillsides, reservoirs and open spaces next to fish ponds. The worm bed is 2 meters wide and unlimited in length. The earthworm bed of large-scale breeding is 5 meters wide, leaving a 70 cm wide walkway in the middle. The two rows of earthworm beds on both sides of the aisle are 2 meters wide, and a good drainage ditch is opened.

Feed management of red earthworm

1. Feed preparation: earthworm feed can mix livestock and poultry manure, melons, fruits, vegetable edges, leaves, etc., in a shallow pool of animal manure, and feed earthworms after 5 to 10 days.

2. Feed feeding: earthworms stack the material into the shape of plum blossom when feeding, the distance between the materials is 5-8 cm, and the pH value is 6-8.

3. Feeding quantity: the food intake of earthworms is equal to their own body weight. Generally, it takes about 70,80 tons of animal manure and organic waste to produce 1 ton of fresh earthworms.

Culture methods of Red Earthworm

1. Moisturizing and ventilation: the moisture content of the earthworm bed should be 30-50%. The high temperature period should be watered every day, the cool period should be watered every 5 days, and the low temperature period should be watered once every 10 to 15 days. Good ventilation should be achieved while keeping the earthworm bed moist.

2. Temperature control: the suitable growth temperature of earthworm is 18-25 ℃, and its egg hatching is also closely related to temperature. Therefore, artificial breeding earthworms should do a good job of temperature regulation in cold and summer, so that earthworms can grow and reproduce in the four seasons.

3. Prevention of natural enemies: the natural enemies of earthworms are frogs, mice, toads, mole crickets, ants, etc., which can be prevented by small-eye fish nets around earthworm farms. In addition, capture and other methods can be taken to prevent natural enemies.

4. Remove earthworm dung: remove earthworm dung when the daily average temperature is about 20 ℃. Clear it twice a year. First shovel out about 20 cm earthworms and dung on the surface of the earthworm bed and put them on the side, then shovel out the underlying earthworm feces and transport them away, and then move the earthworms and dung to the original worm bed.

5. Collection and processing

① collection: after basically eating the feed on the worm bed, take out 2/3 of the adult worms to maintain a reasonable density, keep the earthworms indoors or in the shed temporarily, raise 5 to 6 kilograms per square meter, and feed them with long-stored animal dung and wet concentrate.

② processing: earthworm rich season, choose dry feed such as cornmeal to mix fresh earthworms on a sunny day, and then evenly spread them on the cement field. When the dried earthworms are free of caking and break by hand, the powder can be sifted out and put into a film bag for sale.
