Earthworms can loosen soil and produce manure fields. In the development of aquaculture, earthworm breeding will become an indispensable feed source in protein, and pigs, chickens, ducks and some special products will need a lot of high-protein feed. Earthworm breeding is one of the key breeding projects in the future because of its low cost and high output benefit.
Earthworms can improve soil fertility. When earthworms eat soil and organic matter with microorganisms, with the digestion of food in the digestive tract, some microorganisms also multiply in large numbers, often increasing exponentially from the front end to the back end of the digestive tract. In this way, the number of microorganisms in the feces discharged by earthworms is 10 times more than that in the environmental soil, and there are also many microorganisms in the soil.
Introduction to earthworm:
Earthworms, also known as earthworms, are terrestrial invertebrates of Oligochaeta in annelids. There are more than 3,000 kinds of earthworms in the world, and there are more than 200 kinds in China. There are earthworms, Eisenia foetida, earthworm with different lips, earthworm with dura mater, etc. Widely distributed in China. Earthworms have rich nutrition, rapid reproduction, miscellaneous eating habits, high yield of artificial culture and good economic benefits.
Earthworms can be used as precious drugs to treat many diseases, and also as high-protein food and feed. Earthworms dig holes to loosen soil and decompose organic matter, which creates good conditions for the growth and reproduction of soil microorganisms and plays a special role in soil improvement, eliminating public hazards, protecting ecological environment, material circulation and biodiversity. Many countries use earthworms to treat domestic and organic wastes and purify sewage.
