What is the use of earthworms? What are the benefits of earthworms to the environment?

Earthworms feed on animal feces, soil bacteria and humus, thus changing in the body and exerting the same ability as fermentation. Thereby reducing harmful bacteria in the soil and increasing beneficial bacteria.

It is true that the fertilizer efficiency of earthworm manure is twice that of ordinary compost!

Darwin (1809- 1882) wrote the Origin of Species and spent the rest of his life studying earthworms. He said it was called earthworm, a natural cultivator. Recently, it has been called the technician of the ecological department and the indicator of soil health.

What is the function of earthworms?

1. It has rich medicinal value and is mainly used for clearing away heat, relieving convulsion, inducing diuresis and dredging collaterals. Earthworm dung is rich in beneficial microorganisms, which can promote the growth of plants and increase their antibacterial and disease-resistant abilities. Vegetables and fruits have recovered their original flavor and varied amino acids. Earthworms died, which also played a nutritional role.

Second, earthworm culture can avoid the harm of pesticides and heavy metals.

Third, the role played by the above:

1, the ability to control pathogenic bacteria and nematodes.

2, in order to find food to dig a hole, a day 180 meters, improve 9 liters of soil.

3. Earthworm dung contains fertilizer. The fertilizer consists of 2% nitrogen, 1% phosphorus, 1.5% potassium, 65% organic fertilizer and trace elements. The output can be increased. Composting can last for five years (Cuban experience).

4. Earthworms dried 60% of protein after death, which is rich in amino acids. Applying 4 tons of earthworm compost to Cuba 15 mu farmland has significantly increased production!

There are many kinds of earthworms, such as Dapinger in Japan, which has the advantage of high reproductive ability but low breeding ability.

The advantage of earthworms is that they are deeply ploughed and have great breeding capacity. Orchards are not fertilized or cultivated. It is more than 23 cm long and 1 cm wide, and its activities can make the soil no longer harden. We visited the earthworm garden, and we were surprised at the breeding ability of earthworms.

For example, peach trees can achieve the effect of other fruit trees in three years in one year. A three-year tree is like a five-year tree. Not sick, growing fast.

The fruit is big, sweet and delicious, and can be sold at a good price.

It takes a year for barren soil to become fertile soil.

After applying raw cow dung, weeds in the soil are removed and straw is put in the soil. Fermented manure is turned into the soil with a cultivator, and earthworms (earthworms) are added.
