How to raise earthworms at home

Speaking of earthworms, many people may not like it, think it is very dirty, like to live in dark, damp and dirty places, but the value of earthworms is very great, it can not only be used as feed for raising chickens and ducks, but also has great medicinal value.

How to raise earthworms at home

It's very simple, the first step is to have a foam box, preferably a big one, depending on the situation, then put on the soil, be soft, don't use clay, OK, put in earthworms, keep 60% moisture, you can feed rotten vegetables, rotten fruits and organic garbage, and that's it. It is found that there are a lot of small earthworms in it, and when the density is very high, it will be divided into boxes.

The living environment of earthworms

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.

Generally speaking, the active temperature of earthworms is in the range of 5 ℃ and 30 ℃, 0 ℃ enters dormancy state and dies below 0 ℃. The most suitable temperature is about 20 ℃, which can grow, develop and reproduce well. It can maintain a certain growth when 28 ℃ is 30 ℃, stop growing when it is more than 32 ℃, slow down when it is below 10 ℃, die when it is more than 40 ℃, and the optimum incubation rate of worm cocoon is 18 ℃. It can be seen that the maximum lethal temperature of earthworms is lower than that of other invertebrates.

The farm is best indoors, in the south, it is ventilated and moisturized in summer, and it can be produced normally throughout the year as long as the windows are closed in winter (the temperature here refers to the temperature of the base material, because the temperature of the air is different from that of the base material, for example: when the air temperature is 0 ℃, the base material temperature is about 12 ℃; when the air temperature is 38 ℃, the base material temperature is only about 28 ℃, this is because the dung contains very high moisture).

The efficacy of earthworms

Earthworms can loosen soil, increase soil organic matter and improve soil structure, but also promote acidic or alkaline soil to become neutral soil, increase available components such as phosphorus, and make soil suitable for the growth of crops. As earthworms are rich in protein, they can be used as feed for livestock, poultry and aquaculture to increase production. Earthworms also play a certain role in pharmacology and are common traditional Chinese medicines, which have the effects of antipyretic, antispasmodic, activating collaterals, relieving asthma, reducing blood pressure and diuresis.

Earthworms can secrete a special enzyme that can decompose protein, fat and lignocellulosis. therefore, leaves, rice straw, livestock and poultry manure, domestic waste, activated sludge and scraps of paper and food industry can be its food. Earthworms can eliminate environmental pollution to a certain extent. Therefore, many countries have set up earthworm breeding plants, which are called "environmental purification devices". Because earthworms can absorb trace metals such as mercury, lead and cadmium in soil, the accumulation of these metal elements in earthworms is 10 times higher than that in the outside world. Therefore, some scientists believe that earthworms can be used as monitoring animals for heavy metal pollution in soil.

Nutritional value of earthworms

According to the determination, the protein content of earthworms is about 53.5%-65.1% of the dry weight, the fat content is about 4.4%-17.38%, the carbohydrate content is about 11%-17.4%, and the moisture content is 7.8%-23%. Earthworms are also rich in vitamin D (about 0.04%-0.073% of fresh body weight) and mineral elements such as calcium and phosphorus (about 0.124%-0.188% of fresh body weight). Earthworms contain a variety of medicinal ingredients, such as earthworm, earthworm detoxification, xanthine, antihistamines and vitamin B. At the same time, earthworms are also the intermediate hosts of some parasites such as nematodes and tapeworms, such as nematodes and nematodes.

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.

In fact, there are many functions of earthworms, and many people may not know very well about earthworms. First of all, they live in soil and can improve the properties of the soil. Secondly, they can eliminate environmental pollution to a certain extent. Therefore, do not underestimate this small earthworm, its role and value is still very great.
