1. How to raise water earthworms and water earthworm breeding technology

I don't know how to reproduce it, but I know how to keep it alive. When it is kept in a shed, it should be placed in a cool place. A small amount of water should be added, about 0.5 cm deep. It should be washed once a day. Don't use tap water. It's better to use overnight water.

2. How to keep red nematodes and water earthworms alive? I want to keep them in a basin for fish to eat.

I have a friend whose father is just like you. He has a puppy house in his yard. Of course, there are soil and earthworms in it. Of course, it is a wetland. He puts banana peels and other raw vegetable leaves in it. . .

3. Seeking earthworm breeding technology

Fresh cow dung can be used directly to raise earthworms without fermentation. If there are rotten fruits, rotten leaves, etc. mixed with cow dung, the effect of raising earthworms will be better. First, pile the cow dung into a dung pile with a length of 2 meters, a width of 1 meter, and a height (thickness) of 35 centimeters. Use an iron rake to loosen the top cow dung every day. The thickness of the cow dung that is 50% dry needs to be loosened to about 5-8 centimeters. When it is about 50% dry, you can put earthworm seeds in it. Each pile of dung can be put into 30,000 egg-laying earthworms. Collect the earthworm manure and earthworm cocoons every 10 days and open another pile for incubation. Take the earthworm cocoons every 10 days and open another pile for incubation to ensure that the size and specifications of each batch of earthworms are consistent. If the earthworm manure is found to be dry during the breeding period, spray EM water in time, and mix EM with clean water or rice washing water or rice soup in a ratio of 1:5 and spray it. Generally, spray it every 3-5 days. The earthworms raised by the above method grow fast and produce more and larger earthworm cocoons. Note that poultry and livestock manure must be fermented with EM or dried in the sun and mixed with a water content of about 60% before it can be used to raise earthworms. Earthworm breeding technology As an industry, earthworm breeding has flourished in my country, and its products have been widely used in industry, agriculture, medicine, environmental protection, animal husbandry, food and light industry. In 2004, earthworms were used for more than 10,000 tons of medicine alone. Earthworms can also be processed into disease-resistant high-protein animal feed. The use of earthworm manure is also very extensive. Special fertilizers for flowers, lawns, fruit trees, green vegetable fertilizers, and earthworm manure have been developed. Feed for livestock and fish. As a sunrise industry, the earthworm industry has broad market prospects and development space. Breeding technology Earthworms are burrowing animals that like warmth, humidity, quietness, and darkness. They spend their entire lives in the soil. They feed on rotten organic waste and like to eat sweet and sour food. At present, artificial earthworm breeding mainly uses cow dung, and some use sugar residue, pig manure, chicken manure, crop straw and domestic garbage. Earthworms suitable for artificial breeding should be selected from those with fast growth and development, strong reproductive capacity, wide adaptability, long lifespan, and easy domestication and management. At present, the best varieties are Daping No. 2 and Beixing No. 2, which are artificially domesticated varieties of Eisenia fetida. Other varieties include Pheretima annuli, Eisenia fetida, Dura earthworm, etc. The variety promoted by our company is Daping No. 2. Living habits of earthworms Earthworms are cold-blooded animals, and their body temperature changes with the changes in external temperature. Generally speaking, the activity temperature of earthworms is within the range of 5℃-30℃, 0℃-5℃ enters a dormant state, and dies below 0℃. The most suitable temperature is 15℃-25℃. In this temperature range, earthworms can develop and reproduce best, and die above 40℃. The most suitable incubation temperature for earthworm eggs is 20℃-25℃. The above temperature refers to the base material temperature. For example, when the air temperature is 0℃, the base material temperature is about 12℃. When the air temperature is 38℃, the base material temperature is only 28℃. This is because the base material contains a lot of water. The treatment of the base material is generally divided into two methods: ventilation drying and fermentation. The fermentation method is the best for treating the base material. Earthworms do not have special respiratory organs. They use their skin to breathe, so the earthworm body must be kept moist. Generally, the base material humidity should be kept at about 60%. Earthworms also have a temporary tolerance for different humidity conditions. In order to survive, they sometimes move to a suitable environment, and sometimes reduce water consumption by hibernation, diapause, and reducing metabolic intensity, but this will seriously affect the growth and economic benefits of earthworms. Earthworms are hermaphroditic animals, free of diseases, with a very high reproduction rate and a lifespan of generally 1-3 years. After 21 days of hatching, earthworm eggs grow to sexual maturity after about 60 days of growth. Adults mate and start laying eggs after 5-8 days, and then lay an egg every other day. The first three eggs hatch 1-3 earthworms per egg, and the subsequent eggs hatch 4-7 earthworms per egg. The growth of earthworms slows down after 100 days, so our earthworm benefits are highest when the earthworms grow to 90-100 days. Breeding method: Open-air breeding: Choose a plot with good drainage. First, level and suppress the land. Make the treated base material with a bed width of 1.1 meters and a road width of 1 meter. The height is between 15-20 cm. Then water it twice, turn the base material over, and water it again. When the moisture of the base material reaches about 60%, you can plant the seeds. The most economical density of earthworms is 3000-5000 per square meter. Pay attention to the following five points in management: First, turn the bed about one month after planting, second, pay attention to moisturizing and cooling in high temperature seasons, third, pay attention to drainage in rainy days, fourth, use plastic sheets and straw curtains to cover before winter to ensure the safety of earthworms overwintering, and fifth, pay attention to the temperature, humidity, egg laying, hatching, feeding, enemy intrusion and abnormal phenomena of the earthworm bed every day. Indoor or greenhouse breeding: The breeding management method is basically the same as open-air breeding, mainly paying attention to ventilation and winter insulation. As long as the indoor and greenhouse temperatures are maintained in winter, the economic income will be 15%-30% higher than the open-air breeding method. Benefit analysis: The first-year investment is calculated based on one mu of land: 100 cubic meters of base material, 40 yuan/cubic meter, totaling 4,000 yuan, 210 kg of earthworm seeds, 20 yuan/kg, totaling 4,200 yuan, land occupation fee 300 yuan/mu, production cost 1,500 yuan, total investment per mu 10,000 yuan. The first-year income: 1,500 kg of earthworms, 8 yuan/kg, totaling 12,000 yuan, 30 cubic meters of earthworm manure, 120 yuan/cubic meter, totaling 3,600 yuan, total income per mu 15,600 yuan. Net profit: 15,600 yuan-10,000 yuan=5,600 yuan. After the second year, since there is no need to invest in earthworm seeds per mu, and the earthworm yield per mu can reach 2,000-2,500 kilograms, and some production materials can be reused, the net profit per mu can reach 15,000-20,000 yuan.
