Earthworms improve the soil and what is the impact of organisms on the environment

Organisms must adapt to the environment in order to survive, such as plants in the desert must be drought tolerant to survive, organisms can also affect the environment, such as earthworms improve the soil, thousands of miles of embankments are destroyed in anthills, and the transpiration of plants can increase air humidity.

The body of the earthworm is long cylindrical, which can reduce the resistance of drilling The body surface has mucus, which can also reduce the resistance when drilling the soil, and can also maintain breathing and adapt to life in the dark soil;

Earthworm drilling loosens soil, and earthworm excretion increases soil fertility, indicating that bioenergy affects the environment. As a result, earthworms live in moist, loose, organic-rich soils, and the activity of earthworms can alter the soil and improve its fertility – suggesting that organisms can adapt to a certain environment and can also affect the environment

Loosen the soil and improve the soil. Earthworms dig holes to loosen the soil, decompose organic matter, create good conditions for the growth and reproduction of soil microorganisms, and play a special role in soil improvement, elimination of pollution, protection of the ecological environment, material cycle, biodiversity, etc.

Earthworms contribute to the material cycle and energy transfer of soil processes through activities such as feeding, digestion, excretion (vermicompost droppings), secretion and burrowing, and are one of several soil invertebrate groups (mainly earthworms, mites and ants) that have an important impact on the processes that determine soil fertility, and are known as "ecosystem engineers".

Earthworms affect and alter the soil environment through activities such as feeding, digestion, excretion (vermicompost droppings), secretion (mucus) and burrowing. Earthworms are rich in various enzymes and have the ability to transform and modify organic matter. It can decompose soil minerals to a certain extent and convert them into donable compounds that can be easily used by plants.

Vermicompost rich in soluble nitrogen, phosphorus and potassium can improve soil fertility.

The earthworm has strong reproductive ability, short reproductive cycle, developed digestive system, and large amount of soil, which promotes the integration of soil and fertilizer.

Most of the nutrients converted by the earthworm intestine are compounded with the soil and become a nutrient-rich, high-quality aggregate structure in the soil.

These aggregate structures have the characteristics of loose and porous, strong water stability and more effective nutrients, which improve the aeration and permeability of soil, water storage and fertilizer retention capacity, and water resource use efficiency.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: What does earthworms mean that earthworms can improve the soil:

Earthworms can improve the soil, indicating an increase in organic matter content. The main role is divided into two aspects, on the one hand, the earthworm increases the soil air content through peristalsis, and then increases the oxygen content in the soil. Earthworms prefer to live in dark, damp soil.

Therefore, in the process of survival, earthworms will continue to create such a living environment for themselves. After rains, especially in spring and summer, the soil tends to harden and harden, so that earthworms continue to wriggle in the soil until they are able to wriggle from the soil and pour fresh air from the ground air. In the process of earthworm wriggling, earthworms also make the hardened and compacted soil loose, so that the soil has better water permeability and air permeability.

As an earthworm does not like dryness, standing water and insufficient food.

Earthworms, also known as earth dragons, are terrestrial invertebrates of the phylum Annelids.

Earthworm is one of the annelids, there are more than 3,000 species of earthworms in the world, and there are more than 200 species in China. There are ringworms, Aisheng worms, heterolip worms, dura worms and other varieties widely distributed throughout the country.

Earthworms are rich in nutrition, rapid reproduction, miscellaneous diets, and high yield in artificial breeding. Good economic benefits.

Earthworms contribute to the material cycle and energy transfer of soil processes through activities such as feeding, digestion, excretion, secretion and burrowing, and are one of the many soil invertebrate groups that have an important impact on the processes that determine soil fertility, and are known as "ecosystem engineers".

The economic value of earthworms:

1. Earthworms travel through the soil and devour the soil, which can loosen the soil and improve the physical and chemical properties of the soil. The soil that passes through the earthworm digestive tube is discharged into vermicompost, which contains several times higher nitrogen, phosphorus and potassium than the general Shenwang soil, and is a high-efficiency organic fertilizer.

2. Vermicompost can increase humus, which plays a great role in the formation of soil aggregate structure, some people estimate that the soil aggregate structure formed by earthworms in woodland or orchard reaches 47t-170t per hectare every year, and increases nitrogen by 75kg-125kg.

3. At the same time, earthworms can also convert acidic or alkaline soil into near-neutral. Earthworms contain high protein, accounting for about 50%-65% of dry weight, containing 18-20 kinds of amino acids, of which more than 10 kinds are necessary for livestock.

4. Therefore, earthworm is a kind of animal protein added feed, which has an obvious effect on the yield improvement of poultry, livestock and fish. Earthworms contain delotonin, a variety of amino acids, vitamins, etc., which have the functions of antipyretic, sedative, asthmatic, antihypertensive, diuretic, etc., and have been used in medicine since ancient times.

5. Earthworms have a great ability to swallow soil and organic matter, and can be used to treat urban organic waste, protect the environment, prevent pollution, turn harm into profit, and inhibit public pollution.

6. All countries have built factories to breed earthworms, breed earthworms, process waste, and produce organic fertilizers. Earthworms also have the ability to accumulate certain heavy metals (cadmium, lead, zinc, etc.) in the soil, and can collect earthworms to treat the soil contaminated by heavy metals to achieve the purpose of reducing pollution. Earthworms can be used to make food after processing, and there are foreign countries that use earthworms to make biscuits and bread.
