Sichuan girls raise hundreds of millions of earthworms and consume hundreds of tons of garbage every day. Why do earthworms play such a big role?

It is understood that in Xichang, Sichuan, Luo Jingyang opened the dark and humid soil of the earthworm dung production base in Chenbao Village, Hui nationality township, Gao Chao, and the dense red earthworms kept crawling. Luo Jingyang, who deals with dirt, feces and straw all day, can't escape her even though she wears workers' clothes? New farmers? The identity of? Although small, earthworms are full of treasures, which have good ecological and economic benefits and can also drive villagers to get rich. ? Why do earthworms have such a great effect? Let's find out.

Talking about his career, Luo Jingyang was quite excited. Luo Jingyang, who is in his twenties, is from Dechang County, Liangshan Prefecture. After graduating from college, I worked in the beauty industry in Chengdu with a monthly salary of over 10,000 yuan and a stable life. On 20 18, she gave up her comfortable life, quit her job in Chengdu and returned to her hometown of Liangshan. She chose to cultivate earthworms in Chenbao Village, Hui Township, Gao Chao, Xichang City, and started her business. Luo Jingyang introduced that returning home to raise worms and start a business is mainly influenced by family members. In 20 14, the Yang family in Cyndi Luo planted more than 300 mu of loquat in Dechang County, and it is expected to make a profit after four years. But by 20 18, the fruit on loquat trees not only produced less, but also tasted bad. Tracing back to the source is the problem of soil hardening caused by perennial use of chemical fertilizers. ? High yield and profit? Our dreams were shattered, but the family lost 3 million yuan after four years of hard work. Seeing that his parents were at a loss for this, Luo Jingyang was very anxious. In order to help her family out of trouble, she looked up a lot of information on the Internet every day and saw this sentence: Darwin, the most famous biologist in the world, said? There is no fertile soil in the world except earthworm dung? . So, she came up with the idea of raising earthworms and producing earthworm manure to improve the soil.

The movement and excreta of earthworms are very beneficial to improve soil quality, and can maintain the permeability and health of soil, which plays a very important role in agriculture. One of the most basic creatures in the world?

Earthworms are also a food source for many higher organisms. Earthworm manure is rich in nutrients and microorganisms such as nitrogen, phosphorus and potassium, and it is the most natural fertilizer. Because earthworms react to most agriculture and herbicides, we can judge the quality and toxicity of soil by observing earthworms.

Earthworms have negative phototaxis, live in moist, loose and fertile soil, and mainly feed on rotten leaves. Most earthworms can eat food equivalent to their own weight every day. It eats soil into the body, absorbs microorganisms, and then discharges indigestible sand.
