It breathe with the water swinging.Water earthworms are happy to live in the mud in the mud waters with rich organic matter, and generally lurks in the mud surface 10 cm to 25 cm, hidden in the mud at low temperature.The water earthworms are darkened and can not be exposed in the sun. The organic rot implant, bacteria, and algae are used to take the soil.Water earthworms are mature for about 2 months, hermaphroditaries, and alien fertilization. Estate Bags are hidden in the cystic earthworm cocoons composed of transparent glue membranes.Generally, one to 4 capsules contains egg cocoons, as many as 7 capsules.Each adult in the reproductive period can excrete 2 to 6 cocoons.When the water temperature is 22 to 32 C, the incubation period is generally 10-15 days, and the life span of artificial cultivation is about 3 months.

Second, pit maintenance method

1. Pitching conditions

Build an ecological environment suitable for the life of aquatic earthworms, which requires micro -flow water, loose soil, rich rotten implants, and avoiding light.The pit ponds can be newly excavated or used to be converted into a puddle that is connected to the ditch.

2. Quotation of planting into the pit

Sex depends on water quality, mud, manure sources and seasons.The source of Fertilizer and mixed feed, large quantity, high yield.Generally, 0.25 to 0.5 kg is placed per Square meter.After training for 30 to 45 days, the daily income volume per mu can reach 10 to 15 kg, up to 48 kg.

3. Management

Keep micro -flowing water to make the water quality fresh, the amount of dissolved oxygen is high, accelerate the relaxation of metabolites, and increase the feeding growth of earthworms.The flow rate of general water flow is 2 to 8 cm/s.The speed should not be too fast. If it is too fast, the water flow will be washed away nutrients and the cocoon, which affects the output.After the earthworm is cooked, it should be feed every 2 to 3 days.If you are invested, the bait coefficient is about 2.6; if you use pigs and cow dung, the bait coefficient is 7.8 to 10.4.

4. Harvest

You can reduce the flow or break the water at night, causing hypoxia in the pit the next day or the morning, and the water earthworm will be forced to gather into the mud surface or float until the water surface, and use fishing.
