Can foam boxes raise earthworms?

When it comes to earthworms, many people are as scared as editors. Although earthworms don't bite like snakes, they still give editors goose bumps when they think of them. But we have to admit that earthworms do have a great use in our lives, so now many farmers have turned their attention to the way of raising earthworms.

Can foam boxes raise earthworms?

Yes, just keep them in a foam box and bury some fruit peel, rotten vegetable leaves and the like in the box regularly every week. But design needs to be scientific. The earthworm box is in the corner, there is no sunlight to shine on, the bottom of the earthworm box is perforated, and the box below is full, so the food will be put into the last box, and the earthworms will climb up by themselves, and the lid of the foam box will be full of holes. Cover with an insect-proof net made of pantyhose, which can not only prevent insect invasion but also prevent earthworms from escaping, and a moisturizing layer made of cardboard is added between the lid and the culture medium. Pay attention to leaving some gaps on all sides to facilitate ventilation. When the temperature is high, prepare two bottles of mineral water, put them in the freezer, freeze for a day, put one bottle into the earthworm box, and replace the two bottles of mineral water in turn the next day.

The latest scientific technology of breeding earthworms

First, humidity

Earthworms have no special respiratory organs, they use the skin to breathe, so the body of earthworms must be kept moist. If you put the earthworm in a dry environment, the skin of the earthworm can not remain moist after a period of time, so it can not breathe normally. The earthworm will have spasms immediately and will die soon.

Second, temperature

Earthworms are variable temperature animals, and their body temperature changes with the change of external environment temperature. Therefore, the dependence of earthworms on the environment is generally more significant than that of constant temperature animals. environmental temperature affects not only the body temperature and activity of earthworms, but also the metabolism, growth, development and reproduction of earthworms. and temperature also has a greater impact on other living conditions, thus indirectly affecting earthworms. Therefore, temperature is one of the most important living conditions for earthworms.

III. Ventilation

Earthworms breathe through the oxygen spread into the soil by the atmosphere. The better the soil aeration, the more vigorous its metabolism. Not only there are many spawning cocoons, but also the mature period is shortened, so the yield of box culture is the highest. Because the box can be ventilated on all sides. Earthworms can not live in an environment with high contents of carbon dioxide, methane, fluorine and hydrogen sulfide. If the hydrogen sulfide and methane in the habitat are excessive, earthworms will flee or even die in large numbers.

IV. Food

Food is a long-term and key ecological factor affecting earthworms. The lack of food will make the competition among earthworms fierce, especially in the case of high breeding density, the competition for food among individuals will intensify, which often leads to the decline of fecundity, the spread of diseases and insect pests, the increase of mortality, the escape of some earthworms and so on. The effect of food on earthworms is not only reflected in the quantity of food, but also reflected in the quality of food.

Fifth, pH (PH value)

Earthworms are very sensitive to acids and bases, because all parts of the body surface of earthworms are scattered with chemical receptive organs such as acid and alkali. Earthworms can not survive in a strong acid and strong alkali environment, but have a certain ability to adapt to weak acid and strong alkali environment. Daping No. 2 earthworm grows better in the range of PH value 6mur8, and produces the most cocoons in the range of PH value 7mur7.5.

VI. Density

Density refers to the number of earthworms per unit area or volume. The size of culture density will affect the change of environment to a great extent, so it has a great influence on the yield and cost of earthworms as a whole. The density is small, although the competition for individual survival is not fierce, and the multiplication multiple of each earthworm is large, but the multiplication multiple of earthworms in the overall area is small, and the output is low and consumes more manpower and material resources. If the stocking density is too high, due to the shortage of food and oxygen, the metabolites accumulate too much, resulting in environmental pollution, crowded living space, intensified competition for survival among earthworms, slow weight gain of earthworms, decline in fecundity, spread of diseases and insect pests, increased mortality, survivors escape and so on. Therefore, mastering the best culture density is a key to create the best benefit.

7. Salinity

Some people did an experiment on the tolerance of earthworms to salinity. William's ring-haired earthworms were placed in 0.02%, 0.1%, 0.4%, 0.8%, 1.6% salt solution and 0.01%, 0.02%, 0.04%, 0.08% copper sulfate solution, respectively. observe the time of death of earthworms. The death time of earthworms in the solution with salinity of 0.8% and 1.6% was 145 minutes and 52 minutes respectively, while the earthworms in other salt solutions did not die for 24 hours and had a certain bearing capacity.

8. Lighting

Although earthworms have no eyes, there are many light cells scattered on the surface of the whole body, and they are more in the front (preoral lobe) and back end of the body. Blue light is irritating to earthworms, red light is not, and ultraviolet light is harmful. Therefore, the breeding ground should avoid direct sunlight, and it is best to raise and light a red fluorescent lamp indoors.

The benefit of earthworm culture

Due to the progress of science and technology, people have made deep studies on the medicinal components and pharmacological effects of earthworms by using advanced science and technology. it has been proved that earthworms have a variety of pharmacological functions, and many clinical experiments have been done. It has been proved to be very effective. According to analysis, earthworms contain a variety of medicinal ingredients, such as earthworm, earthworm antipyretic hormone, earthworm toxin, Huang Chuyin, antihistamine, choline, cholesterol, nucleic acid derivatives, B vitamins and so on.

Earthworm mainly contains tyrosine, can expand bronchi, has antihistamine effect, can slowly lower blood pressure and promote the contractile ability of uterine smooth muscle. B vitamins have antipyretic function. At present, lumbrokinase can be scientifically extracted from earthworms for the treatment of cerebrovascular infarction and other diseases, and lumbrokinase oral or injection has been put on the market, it has been proved that earthworms can be used for clinical treatment.

They have the effects of antipyretic, sedative, antiasthmatic, antihypertensive, anticonvulsant and can treat edema, amenorrhea, dysmenorrhea, hemiplegia, numbness, cough, asthma, pneumonia, tuberculosis, bronchiectasis, infantile acute and chronic convulsions, madness, epilepsy, pain, hypertension, mouth and eye deviation, rheumatism, arthralgia, cystitis, bladder stones, yellow gallbladder and other diseases.

Earthworms can be found in both folk prescriptions and empirical prescriptions. The extract of earthworm can also treat erysipelas, Gill, ulcer and so on. In addition, the extract of earthworms can also be used in beauty and health products. If the earthworm extract is added to human ointment, frost and film, it can eliminate freckles and prevent solar radiation, which is a good skin care product.

The prospect of earthworm culture

In the early 1980s, a small amount of earthworm culture was carried out in some parts of our country, and as a result, all the farmers were deceived. The thing is, some lawbreakers trumpeted that in order to complete the contract, a large number of seedlings should be supplied and all the products would be recycled. Product recyclers said that they were used to make "Dilong wine" and traditional Chinese medicine, so they recycled it to the public at a high price, causing many people to buy his seedlings in large quantities (up to 1200 yuan per 10,000). When people raise earthworms and sell them to recyclers, there is no sign of them. So at present, some people still talk about raising worms and changing color.

Earthworms can indeed be used as pharmaceuticals. At present, the international market costs 8-150000 yuan or even more per ton of dried earthworms. In addition to treating animal manure, breeding earthworms can also deal with garbage, purify the environment, accumulate fertilizers and other functions. Earthworms can turn rubbish into fertilizer. Japan, the United States, Canada, Myanmar, India, the Philippines, Australia, West Germany and other countries all use earthworms to dispose of garbage, purify the environment, eliminate public hazards and make organic fertilizers. Some countries that cultivate earthworms have developed to the situation of factory breeding and commercial production.

With the continuous increase of people's level of knowledge, there is more and more knowledge about earthworms. Earthworms have a special function, which can turn a lot of rubbish into fertilizer, so earthworms are used to treat garbage in many foreign countries. and it has a certain medicinal value, it contains earthworms in many medicines.
