It is the soil technician.

Earthworms eat animal feces, soil bacteria, and humus to change within the body, exerting the same ability as fermentation. As a result, the number of harmful bacteria in the soil decreases and the number of beneficial bacteria increases.

Vermicompost has twice as much fertilizer as regular compost, that's for sure!

Charles Darwin (1809-1882) wrote "On the Origin of Species" and spent the rest of his life studying earthworms for the rest of his life. He said that it is called the Earth Dragon, the natural cultivator. Recently known as the Ecosystem Technician, an indicator of soil health.

What are the functions of earthworms?

1. Rich medicinal value, mainly used for the effects of clearing heat, suppressing convulsions, diuresis and channeling. Vermicompost is rich in beneficial microorganisms, which promote plant growth and increase plant resistance to bacteria and diseases. Vegetables and fruits have regained their original flavor and are diverse in amino acids.

When earthworms die, they also exert their nutritional abilities.

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

3. Roles other than the above:

1. Control the ability to control pathogenic bacteria and nematodes.

2. Dig a pit for food, 180 meters a day, improve 9 liters of soil.

3. Earthworm manure contains fertilizer components. Fertilizer composition 2% nitrogen, 1% phosphorus, potassium, 65% organic fertilizer, and trace elements. Yields can be increased. Compost can last for five years (Cuban experience).

4. After the earthworm dies, it is dried with 60% protein by weight and rich in amino acids. In 15 acres of farmland in Cuba, 4 tons of earthworm compost were applied, and the yield increased significantly!

There are many varieties of earthworms, such as the Japanese Ohira II variety, which has the advantage of high reproductive ability, but low cultivation ability.

The advantage of the ringworm is that it is deep cultivation and too much cultivation ability. Do not fertilize and tillage in the orchard. With a body length of more than 23 centimeters and a body width of 1 centimeter, its mobility can make the soil no longer compact. We have visited the orchards and are amazed at how well they can farm.

For example, peach trees can be cultivated in one year to achieve the effect of other fruit trees in three years. Three-year trees are like five-year trees. Didn't get sick, and grew very fast.

The fruit is large, the sweetness is high, and the taste is good, so it can be sold at a good price.

Barren soil flowers turn into fertile soil in a year.

After applying cow dung, remove weeds from the soil and place straw in the soil. After fermenting the manure, it is turned into the soil with a cultivator and then put in earthworms (ringworms).

The characteristics of earthworms are: reptile, ring-shaped cylindrical, segmented, without eyes, without ears, but the body can perceive light and has a good sense of touch. There are no bones. Afraid of sun exposure. Hide in the mud during the day and come out to eat at night. Hermaphroditic, allogeneic fertilization.

Earthworms have no eyes, but their whole body can feel light and dark, breathe through **, are afraid of the sun, and can survive if they are cut in half.

Chopping has a chance to become two earthworms, prefers dark and damp soil, and lives by eating soil.

The role of earthworms! It should be loosening the soil, fishing, making feed, feeding the chickens directly, and good earthworms can be exported. Features!

It should be: earthworms have red blood, and if the earthworm's body is accidentally cut off when ploughing the land, you can see red blood flowing from the wounded surface. Most of the blood is water, as well as oxygen, carbon dioxide, sugars, amino acids, inorganic salts, and other molecules and ions dissolved in it.

The red color of blood is due to the presence of hemoglobin molecules that carry oxygen. This is similar to that of vertebrates, but it has no red blood cells (red blood cells) and hemoglobin dissolves in the blood. In this way, the efficiency of oxygen delivery is relatively low.

Earthworms also have a complex vascular system and are distributed in a capillary network. ** Secretes mucus and moists, which earthworms use to breathe, oxygen enters the bloodstream, and carbon dioxide is excreted. Earthworms have a network of capillaries throughout their bodies, where various substances are exchanged, including tissue cells to obtain oxygen and excrete carbon dioxide.

In this way, the blood always flows in a closed system of tubes, like all vertebrates, which we call a closed circulation. Blood flows through closed tubes, and there must be a pump of life – the heart. The earthworm is very special, just as its body is divided into segments without obvious merger, and its heart is also divided into several segments with the front part of the body, generally 4 5, in the form of a ring, like a bulging blood vessel, so there are also called ring blood vessels.

The dorsal surface of the annular heart is connected to the dorsal blood vessels from the back to the front, and the ventral surface is connected to the anterior to the posterior abdominal vessels, and the abdominal blood vessels also have branches that connect to the anterior to the subneural vessels. Compared to blood vessels, the annular heart has thicker muscle walls that can pulsate, and there are valves that open in one direction to ensure blood flow from the dorsal blood vessels to the abdominal blood vessels. Basically, blood flow is powered by the beats of these separate ring-shaped hearts, which are from back to front (in dorsal vessels), from back to abdomen (ring heart), and from front to back (celiac and subneural vessels).

Hope it helps!

Summary. Benefits of earthworms 1. Earthworms can loosen soil, improve soil, improve fertility, and promote agricultural production.

2. Earthworms feed on animal and plant detritus in the soil, often burrow in the ground, turn the soil loose, make water and fertilizer easy to enter and improve the fertility of the soil, and can also promote acidic or alkaline soil to become neutral soil, increase phosphorus and other available components, so that the soil is suitable for the growth of crops.

3. Because earthworms can absorb trace metals such as mercury, lead and copper in the soil, the accumulation of such metal elements in the earthworm is 10 times that of the external content. As a result, some scientists believe that earthworms can be used as monitoring animals for heavy metal contamination in soil.

4. Because earthworms are rich in protein, they can be used as feed for poultry and are the favorite "meat" food of chickens and ducks.

5. Earthworms can secrete a special enzyme that can decompose proteins, fats and wood fibers, so leaves, straw, livestock and poultry manure, domestic garbage, activated sludge and papermaking, and food industry scraps can be its food. Earthworms are able to eliminate environmental pollution to a certain extent.
