Earthworms are harmful to humans, and what are the benefits of earthworms to humans

No. Earthworms are known as "ecosystem engineers" because they are able to have an important impact on many of the processes that determine soil fertility. It forms numerous reaction rings in and out of its body and abroad through activities such as feeding, digestion, excretion, and burrowing, thus influencing the biological, chemical, and physical processes of the ecosystem.

The earthworm ecosystem is not only a consumer, a decomposer, but also a regulator, and its functions in the ecosystem are manifested in the following ways:

1. Effects on key processes such as organic matter decomposition and nutrient cycling in soil;

2. Influence on soil physical and chemical properties;

3. Interaction with plants, microorganisms and other animals.

Benefits of earthworms.

Earthworms prefer to live in moist, loose, organic soils. During the day, the edition moves in the dirt and swallows.

Eating decaying organic matter and soil, pushing the excreted feces towards the holes, forming small dung heaps; Crawl out of the ground at night and devour fallen leaves. In the event of heavy rain or field irrigation, the soil is soaked with water and the oxygen is insufficient, and it will climb to the ground.

Earthworms have many benefits for humans: they move in the soil, making the soil loose, allowing air and water to penetrate more deeply into the soil, which is good for plant growth and can play a role in improving the soil; The feces it excretes are rich in nutrients such as nitrogen, phosphorus, and potassium, which can improve the fertility of the soil, and its body contains a lot of protein and fat, and its nutritional value is very high, making it an excellent feed and food; It can also be used to treat organic waste.

Change the composition and structure of soil materials, make the soil structure softer, and the large organic molecules that are difficult to be used by plants in composition become smaller.

Earthworms are harmful to potted plants. Earthworms are beneficial worm animals that improve soil fertility by loosening the soil and promoting the decomposition and decomposition of organic matter in the soil. Therefore, the more earthworms in the farmland, the better the soil quality and the greater the fertility, which should be protected.

Potted flowers are different, this is because the soil area in the pot is small, and the culture soil is quite loose and fertile, once the earthworm is invited, its reproduction rate is quite fast, although it does not chew the root system of flowers and trees, but it will drill many holes in the potting soil, so that the root system and the soil are separated so that it can not absorb water and nutrients, and in serious cases, the root system will be pushed out of the soil surface, so it should be killed.

Water earthworms, also known as red filaria and red nematodes, are annelids.

Medium-aquatic oligochaetes, body color bright red or flesh red, orange-yellow. They mostly live in the gutter sludge that discharges sewage or wastewater, and can be harmful to health after being ingested by the human body.

The earthworms are dense on the surface of the sludge, one end is fixed in the sludge, and the other end extends out of the sludge to shake in the water, and immediately retracts into the sludge when it encounters alarm. The nutritional value of the earthworm is extremely high, and it is repeatedly rinsed in clean water before feeding, it is goldfish and koi.

Very favorite bait, but also the main bait for eel seedlings and young turtles, Sichuan area.

It is often used for fishing and is the best bait.

EarthwormsNon-toxic, earthworms can be used as a precious medicine for many diseases, and can also be used as high-protein food and feed.

Earthworms are a common type of terrestrial annelid.

It lives in the soil at night and feeds on livestock and poultry manure and organic waste, which is swallowed along with the soil, and also feeds on decaying stems and leaves of plants. Earthworms can loosen soils, improve soils, improve fertility and increase agricultural yields.

Most ecosystems in the world.

earthworms exist in China, but the ocean is a natural barrier for earthworms, and desert areas and year-round ice and snow areas are also rare. They are mainly found on the surface of the soil, where organic matter is abundant. The structure of the soil, pH.

Water content, aeration, etc. are all factors that limit its distribution and quantity.

Earthworm living habits.

Generally speaking, the activity temperature of earthworms is 5-30, 0-5 enters a dormant state, dies below 0, the optimal temperature is about 20-27, and it is also the most suitable temperature for cocoon eggs, and when it is above 32, it stops growing and dies above 40.

Earthworms use ** to breathe, so the earthworm body must be kept moist, earthworm body water accounts for more than 75% of body weight, prevention of water loss is the key to earthworm survival, so the humidity of the feed should be kept at about 70%.

A small amount of earthworms is beneficial to humans.

1.Earthworms are originally beneficial to plants, can loosen the soil, and can make fertilizer.

2.But too many earthworms are not good, there are many bacteria in the earthworm body, these bacteria are very bad for the human body, and it is also good for plants, there are more earthworms, there are more bacteria in the soil, and there are thousands of earthworms, which is also a bad ecological environment, their nutrition comes from the first place, too many earthworms will inevitably consume the dissolved oxygen in the soil moisture, which will cause the breathing of the plant roots to be not guaranteed, and the plant will suffocate.

After all, earthworms play a lot of roles in the environment, such as maintaining the stability of the habitat environment, but this is placed in the field or something, the harm of the earthworm is that it carries a parasite that may cause the spread of the virus, in addition, you put the pot outside, because there is less soil in the pot, the earthworm will gnaw the roots of the flower, and then the flower will die.
