Earthworm, also known as Dilong, is a terrestrial invertebrate of the phylum Annelida, class Oligochaeta. Earthworms are often used when fishing, but in fact the value of earthworms is not limited to fishing; they have great potential in nutrition, medicine, and economics. Here let us take a look at the price of earthworms in 2019, as well as the value of earthworms.
1. The price of earthworms
The price of earthworms on the market is not uniform, prices fluctuate greatly from year to year, and the price gap for earthworms in different regions is very large. Live commercial earthworms are generally 5 to 8 yuan per jin, and breeder earthworms are about 45 yuan per jin. Generally, 7 to 8 jin of live commercial earthworms can be sun-dried into 1 jin of dried earthworms. The price of dried earthworms depends mainly on the place of origin and whether they are split open and cleaned of sand and mud. In Guangxi, fully split open and cleaned of sand and mud, the 2019 price was around 210 yuan/kg; in Shanghai, fully split open and cleaned of sand and mud, around 150 yuan/kg; in Hainan, fully split open and cleaned of sand and mud, the earthworm price was around 225 yuan/kg.

Earthworms exist in most ecosystems in the world; apart from the ocean, polar regions, and desert areas, it can be said that earthworms can be seen almost everywhere. Earthworms are mainly distributed in the surface layer of the soil, where organic matter is relatively abundant, and earthworms happen to feed on rotting plants or other organic matter, which makes it very suitable for them to survive.
2. The value of earthworms
Earthworms have very high economic value. They are rich in protein, and farming earthworms is an effective way to solve the shortage of animal protein feed. Vermicompost is a high-quality inorganic fertilizer and can be used to develop ecological agriculture. In daily life, they dig burrows and loosen the soil, decompose organic matter, and create good conditions for the growth and reproduction of soil microorganisms. At present, many countries use earthworms to treat household waste and organic waste and to purify sewage.
Earthworms also have very high medicinal value. In ancient traditional Chinese medicine texts, earthworms are called “Dilong”, and they are listed as a lower-grade item in the Shennong Bencao Jing, with the effects of clearing heat and calming convulsions, unblocking collaterals, relieving asthma, and promoting urination. Clinically, they are used to treat cardiovascular and cerebrovascular diseases. With the in-depth development and application of earthworms in medicine, health products, feed, fertilizer, cosmetics, and other aspects, the demand for earthworms at home and abroad is increasing day by day.
Not only that, earthworms also have very high nutritional value. They themselves contain substances such as fatty acids and linoleic acid, and have effects such as fighting cancer, lowering blood pressure, preventing arteriosclerosis, and nourishing the skin. Although the nutritional value of earthworms is also very high, they may need to be made into earthworm powder before people can accept them.
The above is some knowledge about earthworms. In the recently popular film The Wandering Earth, dried earthworms also appeared. I wonder whether you readers can accept this kind of food?
