Leech processing technology? Leech culture technology

There are many kinds of processing methods, but now there are only two kinds of leech dry goods in the market, one is clear water hanging dry goods. The second is parallel goods.

**And the volume of goods is also the best of these two processing methods, personally I think you still learn these two processing methods.

The method we have in the space is explained.

Summary. The processing method of the leech to be used in medicine is as follows, pro.

How are leeches to be used for medicine processed?

The processing method of the leech to be used in medicine is as follows, pro.

Harvested in summer and autumn. After catching, it is washed, smothered with lime or wine, and then dried or roasted. Japanese leeches are usually threaded through the middle of the body and hung to dry; In addition to threading the leech, one end of the body is elongated to make a narrow strip.

Due to the different shapes after processing, it is guessed that the dried products of Japanese medical leeches are called in the chain materials"Leeches"The dried product of the ear stove with a wide body of golden leech is called "wide leech", and the dried product of the brown leech is called "long leech". "

1 wide leech: summer and autumn as the peak production period, the middle of the lake is large, the paddy field is small, take out the sun to dry the Hui Cong, or put it in the pot to dry.

2 Long leeches: The harvesting method is the same as that of the medicinal herb net, but after fishing, use a thread to thread it, elongate one end of the body, and hang it in the sun to dry.

3 Leeches: the same as leeches during the harvest period, after fishing, wear them with a thread, wear them often from the middle of the body, and hold them in the sun to dry.

First of all, the celery leech can be burned to death, and even a long lack of water will make it die, and the knife cut will not generate many leeches, and each section will die. The medicinal leeches are generally wide-body gold leeches, which are washed with water and then threaded into a string with a needle to dry in the sun.

Leeches generally do not drill into the body of the hall, it just sucks a hole on the surface of the human body, secretes a kind of vermiculin from the salivary glands to prevent blood clotting, and can suck a large amount of blood at a time, temporarily stored in the sac, and the nucleus is continuously digested and absorbed by the stomach and intestines.

Dear, if the teacher's help comes to you, please give a thumbs up with a reed stool, your praise is very important to us, thank you. I wish you a smooth work in the future, good health, love you! Stupid Brigade.

Leech is a kind of aquatic animal, and it is also a traditional medicinal aquatic animal in China, which has a very obvious effect on stroke and high blood pressure. And as people study leeches more and more, it is also found that leeches have anti-cancer effects. Its breeding prospects and economic benefits are very impressive.

1. Breeding environment.

The breeding site of leeches should be established in an environment with good wind shelter and suitable light. In spring and autumn to meet the needs of leech growth needs of light, Zhengsen lead and then winter can do a good job of cold protection. A suitable breeding environment is the key to the healthy growth of leeches.

When we establish a farm, we should not only build it reasonably according to the living habits of water quality, but also ensure that the water is of good quality, temperature and humidity, and light is suitable, so as to create a good growth environment for leeches. It is also necessary to minimize costs, reduce costs, and improve the efficiency of breeding.

2. Seedlings are put in.

If it is in the countryside, leech seedlings can be harvested from the wild. When breeding, we have to choose a good breed, and now the most common breeding species are mainly leeches. The growth ability of the golden leech is very strong, with strong reproductive ability, and the yield is relatively stable.

The general breeding period of leeches is concentrated in June, so the stocking time of seedlings should be controlled in spring. The spring environment is very suitable for the growth of leeches, with a suitable temperature, which is very helpful for the growth of leeches, and can usually be harvested and processed around October every year.

3. Bait management.

The bait of leeches is mainly snail meat and plankton, and the flesh and internal organs of various animals are generally selected as bait for feeding. And with an appropriate amount of crop straw, it can be polycultured with some ordinary snails to provide natural bait for leeches. However, it is also necessary to pay attention to the number of snails, not to put too much, otherwise it will affect the growth of leeches, resulting in insufficient growth space for leeches and reducing their reproductive ability.

When feeding the bait, it is necessary to pay attention to the feeding frequency and remove the uneaten bait in time. Especially in summer, avoid high temperature and humidity that will cause the bait to deteriorate and pollute the water quality.

4. Daily management.

The disease resistance of leeches is relatively strong, so our main management work in aquaculture is to regulate water quality. Although wild leeches do not have very strict requirements for water quality, if the water quality changes too much under artificial breeding, it will have a great impact on their growth and reproduction. When breeding, the water temperature should be controlled at about 20-30 degrees, and a certain amount of dissolved oxygen should be ensured.

If there is a lack of oxygen, it is necessary to inject water or increase oxygen in time. Especially in summer, because the temperature is high, the water quality is prone to deterioration, so be careful.

The above is a brief introduction to leech breeding technology, leech breeding technology is actually relatively simple. We only need to do a good job in management and strengthen bait feeding in breeding, so that we can obtain relatively good economic benefits. That's all for today's introduction, this article is for reference only, thank you for reading and supporting.

Leech culture technology

1. Site selection. Choose a place facing south and facing north, sheltered from wind and sun, requiring convenient drainage and irrigation and sufficient sunshine. The pond is 3 meters wide and deep, and the length can be determined according to the size of the site.

The bottom of the pool is grouting with cement, with the principle of no leakage, the pool is set diagonally with inlet and drainage, and the bottom of the pool should be high in the north and low in the south, so as to facilitate drainage and irrigation. The pond is surrounded by loose sandy soil rich in humus to facilitate the laying of eggs by leeches. In the middle of the pond, a platform is built above the water surface to keep it moist, and some stones and branches are placed at the bottom of the pond to supply leeches to inhabit.

2. Water quality. Artificially cultivated leeches have a high density, and need to change the water frequently in the feeding process, and prevent the pollution of chemical fertilizers and pesticides, especially in the high temperature season from July to August, it is necessary to ensure that the water inlet and outlet are unblocked, the water quality is fresh and there must be a certain amount of dissolved oxygen.

3. Seed leeches. The selection of leeches requires individual hypertrophy, with more than 12 grams per leech, strong activity, smooth body surface, bright color without scars, and a stocking density of 20-25 kg per mu (2000-2500).

4. Incubation. Leeches generally breed and lay eggs above 11, and hatch young leeches after 16-25 days. During the spawning period, it is necessary to keep quiet near the pond so as not to alarm the spawning leeches and cause empty egg cocoons.

Avoid walking around the platform during the hatching period to avoid stepping on the egg cocoon. The hatched young leeches can eat the blood of mussels and snails on their own after 3 days, so they should put in sufficient feed, generally 20 kg of snails and mussels per 1,000 leeches, and feed the blood clots of livestock once a week for them to eat freely. However, it is important to keep the water clean by removing blood residue and other leftover food at all times.

5. Overwintering. Under natural conditions, when the temperature drops below 10, they will stop feeding and burrow into the mud for wintering. Artificial breeding can cover straw and other materials around the pond to keep warm and help leeches overwinter naturally.

It is also possible to concentrate the breeding leeches in the plastic film shed for wintering, feed once a half month, and mate and lay eggs when the temperature rises slightly.

6. Natural enemies. The natural enemies of leeches with disease prevention and control mainly include voles, frogs, weasels, snakes, etc., which can be controlled by microgrids and trapped. Under normal circumstances, the vitality of leeches is strong, basically no disease, as long as the water source is not polluted by chemical fertilizers, pesticides and saline-alkaline solutions, keep the water inlet and outlet unobstructed, the food is fresh, remove the feed residues in time, and change the water frequently to raise leeches, otherwise, ** disease and intestinal disease may occur.
