CATDOLL : CATDOLL: Why cow dung can be used to raise earthworms to become organic fertilizer (Why cow dung can be used to raise earthworms to become organic fertilizer)

1. How to breed earthworms with cow dung?

1.

Choose fermented and dried cow dung.

Feeding earthworms with such cow dung not only has good air permeability, but also will not ferment and burn the earthworms

2.

Use water to expand the dry cow dung, then squeeze out the excess water. When the cow dung can be held in the hand and a small amount of water can be squeezed out from between the fingers (the relative water holding capacity is 70% at this time), you can start feeding.

3.

The feed can be covered in a full layer on the breeding bed without worrying about the earthworms being suffocated or burned.

2. Can organic cow dung be used to raise earthworms?

Organic cow dung can be used to raise earthworms.

Earthworm farming is a completely organic farming process. Earthworms are fed with livestock and poultry manure, which is rich in organic matter and is a good organic fertilizer. Each greenhouse covers an area of ​​about 400 mu and can digest about 40 tons of animal manure each year, producing 5,000 to 10,000 kilograms of earthworms per year. Based on the current market price of 10 yuan per kilogram of earthworms, the output value of each greenhouse can reach 100,000 yuan.

3. How to ferment cow dung to breed earthworms?

Cow dung fermentation method: Use straw or stalks to spread a 10-15 cm thick layer of dry material, then spread 4-6 cm dung on the dry material and repeat 3-5 layers. Use a watering can to spray water on each layer until the water seeps out. If garbage is used, pile it up one layer of garbage and one layer of dung.

4. Can cow dung be used to raise earthworms?

Answer: You can use cow dung to raise earthworms.

It is okay to use cow dung to raise earthworms, as there are undigested substances in cow dung that can be absorbed by earthworms. However, you cannot use all cow dung to raise earthworms. Only 35-50% can be used, and other feeds should be added, such as cornmeal, soybean meal, vegetable leaves, minerals and vitamins, etc. Raising earthworms is a technical job that requires carefulness and patience. If you are a fisherman, there will be no problem raising earthworms, because you do it out of interest and hobby, and you will work hard to raise them well.

5. How to ferment cow dung and vegetable leaves to feed earthworms?

Cow dung earthworm breeding technology First, the cow dung is piled into a dung pile of 2 meters long, 1 meter wide, and 35 centimeters high (thickness). Every day, the top cow dung is loosened with an iron rake. The cow dung that is 50% dry needs to be loosened to a thickness of about 5-8 centimeters. Each pile of dung can be put into 30,000 egg-laying earthworms. The Taiping No. 3 earthworm species can be introduced. It is a hybrid of American red earthworms and Japanese Aisheng earthworms. It is currently the most productive earthworm variety. It can withstand low temperatures of -10℃. The body length of the Daping No. 3 earthworm is 130 mm, dark red, flat, thick, without mud in the body, yellow tail, hermaphrodite, all can lay eggs, and it is docile by nature and does not jump or run.

Cow dung earthworm farming technology can be used for composting and farming indoors and outdoors all year round. The feed is mainly cow dung, pig dung and other livestock and poultry feces, rotten vegetable leaves, rotten fruits and vegetables, and various weeds. In winter, according to the size of the outdoor scale, a variety of warming methods are used according to local conditions to make the minimum temperature of the earthworm bed above 10-15℃ to increase the growth and reproduction rate of earthworms. Some farmers lay a layer of film on the earthworm bed. Although the temperature of the earthworm bed can be 8-10℃ higher than the maximum temperature on a sunny day, when the temperature is very low in the early morning, the earthworm bed is only 5℃ higher than the outside.

Daping No. 3 earthworms are suitable for commercial density breeding. At a temperature of 26-30℃, each earthworm can reproduce about 14,000-40,000 per year. 10,000 earthworms are planted per cubic meter of feed. After two months of breeding, 60 kilograms of fresh earthworms can be produced per month. The cow dung earthworm breeding technology uses bamboo frame plastic sheds, which has low investment and good results. The average temperature rises by 10℃ per day. According to the low temperature period of 150 days, the cumulative temperature rise is 1500℃, which is equal to 75 days of accumulated temperature at an average temperature of 20℃. In other words, this is equivalent to 2 months more growth period than general breeding, which makes earthworms grow faster and lay eggs earlier, laying a good foundation for high yield throughout the year. In the cow dung earthworm breeding technology, straw curtains should be hung on the east, west and north sides of the plastic shed, and a straw cage must be placed in the middle of the earthworm bed to facilitate ventilation, and then covered with a layer of film.

In areas with low temperatures, two layers of film can be used to cover the cow dung, with a layer of straw mat between the films. The used cow dung can be directly applied to the field as fertilizer. After being treated with earthworms, the total nitrogen, available nitrogen, total phosphorus and organic matter content of the cow dung have increased. The growth and reproduction of earthworms in the cow dung farming technology accelerates the decomposition and transformation of nutrients in the cow dung, and improves the fertility of cow dung as an organic fertilizer. Cow dung can improve soil fertility, help increase soil water absorption and water holding capacity, and reduce runoff and soil loss.

6. Why do some people say that cow dung can be used to raise earthworms?

In rural areas, especially in cattle farms and dairy farms, the treatment of cow dung is a headache for breeders. It not only pollutes the environment, but also easily breeds flies and insects.

In addition to the natural fermentation of cow dung, microorganisms EM bacteria can also be used to ferment cow dung as the main bedding and feed for earthworm farming, which can more effectively solve the problem of cow dung pollution in cattle farms, making the farms free of odor, not polluting the environment, and generating income. The earthworms produced can be sold to flower and bird markets and fishing tackle shops in surrounding provinces and cities. Generally speaking, the average income per mu of earthworm farming with cow dung can reach more than 20,000 to 30,000 yuan.

【Aquaculture prospects】

In the past, cow dung was mostly sold to nearby farmers for use as compost, with one ton selling for only 20 to 30 yuan. Since it cannot be harmlessly disposed of, the cow dung piled up everywhere has caused headaches for the environment.

The earthworm farm adopts the technology of raising earthworms with cow dung, which can not only process cow dung, but also bring rich economic benefits. Generally speaking, one mu of land can produce about 1 ton of earthworms per year, and the net profit per ton is about 10,000 yuan. The tens of tons of earthworm manure produced each year can also be sold for about 200-400 yuan per ton (the price varies greatly in different places), which can earn thousands of yuan.

Raising earthworms with cow dung not only brings considerable profits, but also achieves "zero emissions" in the production process of dairy cows and beef cattle. It also forms an ecological chain of raising cattle with crop straw - raising earthworms with cow dung to produce green ecological fertilizer - earthworm manure to promote crop production.

【Benefit Analysis】

Earthworms have a wide range of uses, and dried earthworms have extremely high medicinal value. Using cow dung to breed "Taiping No. 2" large red earthworms, the growth period is 2-3 months, and the yield of fresh earthworms per mu is about 2,000 kg. The market price of dried earthworms (the name of the medicine is earthworm) reaches 80-170 yuan/kg, fresh earthworms are 15-30 yuan per kilogram, and earthworm manure is 200-400 yuan/ton. The income per mu can exceed 30,000 yuan.

Fresh earthworms are mainly used in fishing supplies, animal extracts, agricultural and sideline product processing, animal raw medicinal materials, fishing equipment, etc. Earthworms are in short supply and there is never a problem with sales. Even the earthworm feces can be turned into money.

The feces excreted by earthworms contain a large number of beneficial microorganisms and two antagonistic microorganisms. In addition to analyzing various nutrients in the soil, it can also improve the characteristics of soil structure and completely solve the problem of soil compaction. The current market price of this kind of manure fertilizer is 200-400 yuan per ton.

[Risk Warning]

1. Technology: Although earthworm farming has a very broad prospect, it is not easy to succeed in farming. 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, and if the temperature is lower than 0℃ or higher than 40℃, earthworms cannot survive. In addition, earthworms have a relatively large appetite. Cow dung is the best feed for earthworm farming. The daily demand for cow dung is very large. For example, if one kilogram of earthworms is raised in one square meter, one kilogram of cow dung is needed every day. The fermented cow dung must also be added with an appropriate amount of water for earthworms to survive.

In addition to regular feeding and controlling temperature and humidity, earthworm farming also requires the prevention and control of pests and diseases. Leeches, frogs, mole crickets, ants, and mice are all natural enemies of earthworms. The requirements for earthworm farming are relatively high. Don't believe in some advertisements and make large-scale investments without seriously studying earthworm farming technology. You can try it first and accumulate experience.

2. Market: Before breeding earthworms with cow dung, you must find a stable and large-volume sales channel before you can breed them on a large scale.

3. Varieties: You can certainly raise many batches of earthworms by their own reproduction after purchasing earthworm seedlings once. However, this method can easily cause the degeneration of earthworm varieties, resulting in slower growth, increased mortality, and reduced quality.

【Farming technology】

Cow dung is the most suitable type of manure as feed in manure farming. In order to raise earthworms well, we must make a scientific proportion.

Recipe Example:

① 50% cow dung, 50% pulp sludge;

② 100% cow dung or 100% mixture of all livestock dung;

③ 20% each of cow dung, pig dung, and chicken dung, and 40% of rice straw; (Note: Chicken dung needs to be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will all escape or die.

Feed preparation:

Fermentation: Use straw or stalks to lay a 10-15 cm thick layer of dry material, then lay 4-6 cm of manure on the dry material and repeat 3-5 layers. Use a watering can to spray water on each layer until the water seeps out. If garbage is used, pile one layer of garbage and one layer of manure. The length and width are not limited, and it is covered with a film. In the season with high temperature, turn it over every 7 days. Generally, turning it over 3-5 times completes the fermentation of the feed.

After the feed is fermented, test the pH value. Earthworm feed generally requires an appropriate pH value of 6-7.5, but the pH value of many animal and plant wastes is often higher or lower than this value. When the pH exceeds 9, acetic acid, salt or citric acid can be used as a buffer;

Cow dung to breed earthworms can not only solve the problem of cow dung pollution in cattle farms, but also generate income after the earthworms are produced. The remaining cow dung is the best organic fertilizer, which can be used to make waste and turn it into treasure, achieving multiple goals at one stroke. I hope this can be helpful to friends who want to breed earthworms.

7. How to process cow dung to raise earthworms?

1 Cow dung can be used to raise earthworms after composting. 2 Because earthworms like to eat organic matter, and cow dung is a good source of organic matter. During the composting process, most of the harmful substances in cow dung that are not conducive to the growth of earthworms will be decomposed, and a large amount of heat will be released, which is conducive to the growth of earthworms in winter. 3 When using cow dung to raise earthworms, it is necessary to pay attention to adding an appropriate amount of organic matter, controlling the moisture and temperature, and ensuring the growth and reproduction of earthworms. At the same time, it is necessary to avoid adding cow dung containing chemical substances to avoid adverse effects on earthworms.
