It's possible. Here are some feeding methods: 1. Earthworms can be cultivated indoors and outdoors. In the south, the temperature is high in summer and autumn, and the indoor culture is good. But large-scale cultivation can be carried out outdoors, and solar energy can be used for heating at low temperature. But the venue must be chosen near the water source, where the transportation is convenient. Rural areas can take advantage of the gaps between villages or forests. Water pipes or automatic sprinklers should be installed when the breeding area is large. Insect beds are generally 5 meters wide, and the middle aisle is 70 ~ 80 cm, but the width should be increased if they are fed by cars. The height of the walkway is more than 30 cm, and the width of the two insect beds on both sides is 2 meters. Ditches are dug outside the two insect beds to facilitate drainage. After the worm bed is made, the fermented feed is placed horizontally on the worm bed to form strips with a width of 20-30 cm and a spacing of 10- 15 cm. Before putting earthworm seeds, wet the earthworm bed, then put the earthworm seeds in a place where there is no feed, the stocking density is 0.5 kg/m2 (about 1000), and add some water, which is beneficial to earthworm activities. It is forbidden to put earthworm species on the earthworm bed filled with animal manure to avoid the loss of earthworm species. 2. Feeding red earthworm in Taihu Lake in time has a wide range of food habits, and it eats almost everything, but the key is that the feed must be completely decomposed. Composting takes 30 days, or digging into a pond, it is best to put aquatic plants, grass, fruits, vegetable skins and feet in livestock manure water for fermentation. Because the food eaten by earthworms in a day is roughly equal to their own weight, they should supplement the materials "in time". "Timely" means adding materials after collecting earthworms when there is still 20% feed in the earthworm bed. The filler must be plum blossom-shaped, with a gap of 5 ~ 8 cm between piles. Poultry droppings are too thin to be poured into strips. Leave a gap area of 1/3 ~ 1/4, and add water before feeding. Thunderstorms tend to flatten cow dung that has just been added for a day or two, forming a hardened layer that is airtight. Earthworms are boring and the ground temperature is high. Earthworms on the worm bed will crawl into the ditch, and some will escape to the surface of the worm bed. If there is still unfermented livestock manure producing biogas, the worm will die immediately. Therefore, always observe before and after a thunderstorm. If the grass is not covered after feeding, the newly added livestock manure should be opened 20 cm wide on the insect bed before and after the thunderstorm. In winter, all earthworm beds are covered with a thin layer of material, which will also cause earthworm death. If you don't add material and water for a long time, it will cause the earthworm to shrink, and the earthworm will die if it can't live, but it will leave a batch of egg cocoons. If possible, you can use EM biotechnology, which is a high-tech introduced from Japan by Jiangsu Province 199 1. It is an effective microbial community, such as nitrogen-fixing bacteria, lactic acid bacteria, etc. 18 genera and more than 80 strains. This microbial community has the functions of accelerating the maturation of various organic fertilizers, improving soil fertility, reducing pests and diseases, purifying the environment and promoting the growth of crops, livestock and animals. Spraying diluted EM solution on livestock manure and earthworm manure bait can remove odor, inhibit the reproduction of harmful bacteria and reduce the invasion of lice and flies. Earthworms swallow organic wastes such as livestock manure fermented by EM, and beneficial colonies multiply in their bodies and are absorbed as nutrients, which enhances the disease resistance, and the earthworm grows fast and has a high reproduction rate. 1995 I tried to raise earthworms indoors for 85 days, and the proliferation was 65.9 times, which was 5 1.6 times and 14.3 times higher than that of the control group (sprayed with clean water). Moreover, the earthworm sprayed with EM is slightly thicker and the color is slightly red and powerful. Write these first. 3. Moisturizing and ventilation The earthworm bed is a place to raise earthworms. Pay great attention to temperature, humidity and ventilation. Water it often and keep it moist. Water 1 time every day in summer, 5 ~ 1 time in low temperature period, and 3 ~ 5 days 1 time in cooling period to keep the humidity at 30%. Moreover, grass should be carefully covered all year round to keep it moist and ventilated. This can promote earthworms to eat more, grow faster, lay more eggs, have a high hatching rate of eggs and cocoons, and have a high survival rate of young earthworms. We did a comparative experiment of covering grass in 1994. The results showed that the yield of earthworm covered with grass curtain increased by 80%. In addition, if there is a thunderstorm after grass mulching, the surface layer of the earthworm bed can be prevented from hardening and the earthworm can be prevented from dying from biogas. Poor management of a few farmers in the low temperature period leads to the atrophy of earthworm bodies and the reduction of egg production. There are many reasons, such as not watering for a long time and not adding feed in time. And the most important thing is that there is no good ventilation. Earthworms are dark brown, lack of oxygen and dull, weak, slow-moving, and many offspring die. In particular, livestock manure that has not been completely fermented continues to ferment in the membrane, producing biogas and endangering earthworms. Hypoxia, fish floating head, easy to find, earthworm bed covered with film hypoxia is not easy to find. Only by ventilation, increasing oxygen and discharging harmful gases.
