What kind of soil is used to raise earthworms

Earthworms may be regarded by many people as a useless creature, and sometimes they are particularly annoying when they climb the road. In fact, earthworms play a great role and are of great value. Many people use earthworms as bait when fishing, and earthworms have a certain medicinal value.

What kind of soil is used to raise earthworms

It depends on how you raise it, ground culture and three-dimensional box culture.

1, the ground raises, the feces does not need to ferment, the breeding method, takes the vegetable garden soil 5 cm thick, the cow dung cannot exceed 5 cm, the cow dung 70% pig or chicken dung 30%, cannot exceed 2 cm. Density 1 square meter, earthworms 1 kilogram

2, three-dimensional box culture, do not need soil, feces must be fermented, the method is 100% cow dung. 50% cow dung, 50% straw. Cow dung 70% pig or chicken manure 30%. Density 1 square meter, 25 centimeters, earthworms 5 kilograms.

The risk of raising earthworms with cow manure

1. Environment: although the prospect of earthworm breeding is very broad, it is not an easy task to raise earthworms successfully. Because earthworms have very high requirements for the environment, if the temperature is lower than 5 ℃ or higher than 32 ℃, earthworms will enter a dormant state. If the temperature is lower than 0 ℃ or higher than 40 ℃, earthworms will not be able to survive. In addition, earthworms eat a lot of food.

2. Technology: in addition to regular feeding and controlling temperature and humidity, earthworm breeding is also very important for the prevention and control of diseases and insect pests. Leeches, frogs, mole crickets, ants and mice are all its natural enemies. The requirement of technology for breeding earthworms is relatively high. Do not believe some advertisements and invest blindly on a large scale without seriously learning earthworm breeding techniques. You can try it first and accumulate experience.

3. Market: before raising earthworms with cow dung, we must find stable and mass sales channels before we can breed earthworms on a large scale.

4. Variety: buying earthworm seedlings once can propagate and raise many batches of earthworm seedlings, but this way can easily lead to the degradation of earthworm varieties, such as slower growth, increased mortality, lower quality and so on.

The living habits of earthworms

1. Nocturnal animals: earthworms are nocturnal animals that live in soil caves during the day and go out at night. They usually go out from 8 p.m. in summer and autumn to 4 a.m. the next day. Feeding and mating are carried out in dark conditions. I like the quiet surroundings. Most of the earthworms around the living industry and mine do not grow well or escape. Although earthworms are distributed all over the world, they prefer higher temperatures. When the temperature is below 8 ℃, they stop growing and the optimum temperature for reproduction is 22-26 ℃.

2. Omnivores: earthworms are omnivores. Except for glass, plastic and rubber, earthworms are eaten, such as humus, animal feces, soil bacteria, fungi and the decomposition products of these substances. Sensitive taste, sweet and sour taste, bitter taste, like hot and soft feed, especially gluttonous for animal food, the monthly food intake is equal to their own weight, and about half of the food is excreted as feces through the digestive tract. It has the habit that mother and son are unwilling to live together, especially in the case of high density, when the small ones reproduce and the old ones will run away and move.

3. Negative phototaxis: earthworms have negative phototaxis, especially to escape from strong sunlight, blue light and ultraviolet rays, but they are not afraid of red light and tend to weak light, such as earthworms coming out of their burrows in the wet morning. The toxic effect of sunlight on earthworms is mainly due to the presence of ultraviolet rays in sunlight. Earthworms like quiet environment not only requires low noise, but also can not shake, near bridges, highways, airports is not suitable to build earthworm farms.

4. variable temperature animals: 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.

The culture value of earthworms

1. Chinese herbal medicine: earthworms, commonly known as earthworms, are cold and salty, with the effects of clearing heat, calming the liver, relieving asthma, dredging collaterals, and treating high fever, mania, convulsions, wind-heat headache, red eyes, hemiplegia and so on. The extract has a good effect of relieving cough and asthma, and its ash mixed with rose oil can treat baldness.

2. Biological fertilizer: earthworm manure is a good biological fertilizer, which is rich in nitrogen, phosphorus, potassium, humus, organic matter and trace elements needed by crops such as magnesium, boron, nickel and manganese. It is a cheap and efficient fertilizer for fruits, flowers, vegetables and nurseries.

3. Aquatic bait: earthworms are rich in protein, fat and carbohydrates. The content of crude protein is as high as 72%. It also contains amino acids, vitamins and trace elements needed by the human body. It can not only be used as animal feed and produce drugs and cosmetics, but also can be used for human consumption.

Now in China, earthworm breeding may not be particularly common, perhaps because many people do not have a special understanding of the use and value of earthworms, so earthworm farming still has a lot of room to tap the market and development.
