Earthworm, also known as boa constrictor, is named earthworm in traditional Chinese medicine. It is a kind of mollusk with juicy and soft body and protein content of 70%. Earthworms can use wastes and agricultural by-products as food without competing with other animals for feed, which can improve soil fertility, treat garbage, purify cities and improve sanitary conditions. Earthworms are also the best feed source for pigs, chickens, fish, various animals and rare aquatic products in protein. The research, development and utilization of earthworms by scientists in China mainly include the following six aspects:
First, use earthworms to make Chinese medicine products.
2. Earthworms are used to make health food, medicated wine, medicated diet and oral liquid to strengthen the body.
3. Earthworms are used as raw materials for manufacturing light chemical products, food and feed additives.
Fourth, use earthworms to treat urban garbage, improve the environment and purify the city.
5. Earthworms are high-protein mollusks and the best feed for eels, loaches, ricefield eels, turtles, frogs, turtles, chickens, ducks, pigs, rabbits and other animals.
Six, earthworm dung products have great development value. The green organic fertilizer processed from earthworm manure is a high-grade fertilizer for landscaping and planting flowers and grass. The price per ton of earthworm manure in China is about 1000 yuan. The value of earthworm cultivation, utilization and development is extremely significant. Earthworms feed on cattle, pigs, sheep, horses, chicken manure, rotten fruits, shells, leaves, food and agricultural and sideline products, and do not compete with other animals for feed. Earthworms have short reproductive cycle, high reproductive rate, simple feeding and low investment. Quick effect and high benefit. Every 40-60 days is a cycle, and 6-9 cycles can be cultivated every year. If the feeding management is good, 2-3 tons or 5 tons of fresh earthworms can be produced per mu. According to the current market price, the benefit per mu is 20,000-30,000 yuan, and the profit per mu can reach about 8000- 1 10,000 yuan. Every year, the trade volume of dried and fresh earthworms in the international market can reach $3 billion, and it is increasing by 20% every year. It can be said that people will pay more and more attention to the wide application of earthworms. There is much to be done to develop earthworm breeding.
