Sun Dried Earthworm are a terrestrial animal, living in the soil, nocturnal, with corrupt organic matter for food, together with the soil swallowed together. Also feeding plants such as stems and leaves and other debris. Earthworms can make the soil loose, improve the soil, improve fertility, and promote agricultural production. There are about 2,500 kinds of earthworms in the world, and 229 species have been recorded in our country. Ring hair genus (Pheretima), wide variety, China has more than 2,000 kinds.

Relationship with mankind

Earthworms in the soil of animal and plant debris for food, often in the underground hole, the soil was loose, so that water and fertilizer easy to enter and improve soil fertility, is conducive to plant growth. Earthworms can be used as poultry feed, chicken, ducks like "meat" food; earthworms or freshwater fishing to adapt to a wide range of various waters, fish, climate are more suitable bait. But earthworms are also harmful. There is a parasite in the pig parasites - pig lung filarials, in its larval growth and development, for some time is parasitic in earthworms. Therefore, earthworms provide a convenient condition for the propagation of this parasite in areas where the porcine filariasis is prevalent.

Earthworms and flowers

Pots in the earthworms must also be killed. The pots are placed outdoors and the earthworms are easily drilled from the bottom of the basin into the basin. Earthworms are good in the field, but it is harmful in the pot. The pots of soil less, which will lead to earthworms eating roots of the flowers, as well as earthworms will be a hole, a watering, water along the hole on the flow, the flowers can not drink water. If there are earthworms in the flower pot, you can buy some "trichlorfon" (pesticide) powder in the flower shop, sprinkle it on the surface of the pots, and stir well. Trichlorfon can completely eliminate earthworms. Use the instructions in accordance with the packaging can be. And some that the earthworm feces for the flowers is a fertilizer, the flower is good.

Earthworm regeneration

Earthworm is a low-level animal, although it also has a head, a tail, mouth, stomach and anus. But its whole body is composed of two two-pointed "tube" set together, the outside layer is a ring of body wall, which consists of mesodermal cells composed of muscle system, the body is A digestive tract, from beginning to end through the layers of the middle of the diaphragm. Inside and outside the two "pipe" between the body cavity is filled with.

When the earthworms are cut into two sections, the muscle tissue on the section immediately shrinks, and some of the muscles dissolve themselves quickly to form new cell clusters, and the white blood cells accumulate on the cut surface to form the embolization and the wound is quickly closed. In the body cavity in the interval of the original cells quickly migrate to the cut surface with their dissolved muscle cells together, in the cut on the formation of nodular regeneration buds. At the same time the body's digestive tract, nervous system, blood vessels and other tissues of the cells, through a large number of mitosis, rapid growth to the regeneration of buds. In this way, with the proliferation of cells, the lack of a section of the head of the section, will grow a new head; lack of tail that section of the section, will grow a tail to. Such an earthworm becomes two complete earthworms.
