How much did earthworms cost per jin in 2019?
Earthworm, also known as Dilong, is a terrestrial invertebrate of the phylum Annelida, class Oligochaeta. Earthworms are often used when fishing, but in fact their value is not limited to fishing; they hold great promise in nutrition, medicine and economics. Here let us take a look at the price of earthworms in 2019, as well as their value.
1. The price of earthworms
The price of earthworms on the market is not uniform; prices fluctuate greatly from year to year, and vary widely between different regions. Fresh commercial earthworms generally cost 5-8 yuan per jin, while breeding earthworms cost around 45 yuan per jin. Generally, 7-8 jin of fresh commercial earthworms can be 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 mud and sand. In 2019, the price in Guangxi for fully split and cleaned ones was around 210 yuan/kg, in Shanghai around 150 yuan/kg for fully split and cleaned ones, and in Hainan around 225 yuan/kg for fully split and cleaned earthworms.
Worldwide, 12 families, 181 genera and about 4,000 species of terrestrial earthworms have been recorded; in China, 9 families, 28 genera and 306 species have been recorded. Earthworms exist in most of the world's ecosystems; apart from the oceans, polar regions and deserts, earthworms can be said to be seen everywhere. Earthworms are mainly distributed in the surface layer of the soil, where organic matter is relatively abundant, and earthworms happen to feed on decaying plants or other organic matter, which suits their survival very well.
2. The value of earthworms
Earthworms have high economic value and are rich in protein. Farming earthworms is an effective way to solve the shortage of animal protein feed. Worm castings are a high-quality inorganic fertilizer that can be used to develop ecological agriculture. In daily life, they dig burrows and loosen the soil and decompose organic matter, creating good conditions for the growth and reproduction of soil microorganisms. At present, many countries use earthworms to handle household waste and organic waste and to purify sewage.
Earthworms also have high medicinal value. In ancient Chinese medical texts, the earthworm is called “Dilong”, and it is listed as a lower-grade medicine in Shennong Bencao Jing, with effects of clearing heat and calming convulsions, dredging collaterals, relieving asthma and promoting urination. Clinically, it is 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 fields, demand for earthworms at home and abroad is growing day by day.
Not only that, earthworms also have high nutritional value. They contain fatty acids, linoleic acid and other substances, and have effects such as fighting cancer, lowering blood pressure, preventing arteriosclerosis and beautifying the skin. Although the nutritional value of earthworms is also very high, they may need to be made into earthworm powder before people will accept them.
The above is some knowledge about earthworms. In the film The Wandering Earth, which was very popular some time ago, dried earthworms also appeared. I wonder whether you could accept this kind of food?
