CATDOLL : CATDOLL: How to ferment cow dung to raise earthworms (How to ferment cow dung to raise earthworms)

1. How to ferment cow dung to breed earthworms?

Method of breeding earthworms by fermenting cow dung:

Use straw or stalks (it is better to cut them into small pieces) to spread a layer of dry material (10-15 cm thick) first, and then spread manure (4-6 cm thick) on the dry material. Repeat this 3-5 layers, spraying water with a spray bottle for each layer (EM stock solution is added to the manure pile at this time, one ton of manure requires 10 kg of EM and about 100 kg of water) until the water seeps out; if garbage is used, lay one layer of garbage and one layer of manure, with no limit on length and width, and cover it tightly with a film; if 100% manure is used, first dry the manure until it is 50% to 60% dry, then pile it, wet it with EM diluted with water, and cover it tightly with a film.

2. How to breed earthworms with cow dung?

Cow dung is a good material for earthworm breeding. When using cow dung to breed earthworms, the cow dung selected must be fermented and dried. Feeding earthworms with such cow dung not only has good air permeability, but also will not ferment and burn the earthworms. Before feeding, the cow dung should be expanded with water, and then squeezed to remove excess water. When the cow dung can be held in a ball and a small amount of water can be squeezed out from the fingers (the relative water holding capacity is 70% at this time), it can be fed into the bed. The feed can be covered on the breeding bed in a full layer, and there is no need to worry about the earthworms being suffocated or burned.

Using cow dung to breed earthworms: First, the color is red, and the color is vermilion, which is bright and eye-catching. Second, the smell is fishy, ​​and the smell is unique and pungent. Third, the meat is firm, with less water content, and can withstand fish pecks. Fourth, it is small, like a matchstick, and of moderate size. Fifth, it is fresh and alive, hanging on the hook, swinging and tumbling. Another biggest advantage is that it grows and reproduces quickly. Under the conditions of a suitable temperature of 15-25℃ and a relative water holding capacity of 70%, the reproduction volume can be more than doubled in 15-20 days.

3. What is the simplest way to raise earthworms using cow dung?

1. Feed formula: When feeding, use 50% cow dung, 50% pulp sludge, or 20% each of cow dung, pig dung, chicken dung, and 40% rice straw to feed the earthworms. Chicken manure must be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will escape or die.

2. Feed fermentation: Use straw to spread a layer of dry material with a thickness of about 10-15 cm, and then spread 4 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. In high temperature weather, you can turn it over every 7 days. Generally, the feed fermentation work is completed after turning it over 3-5 times.

3. Feed preparation: After the feed is fermented, the pH value can be tested. The suitable pH value of earthworm feed is generally 6-7.5, but the pH value of many animal and plant wastes will be higher or lower than this value. If the pH exceeds 9, acetic acid, salt or citric acid can be used as a buffer.

4. Cow dung breeding earthworm technology?

Fresh cow dung can be used directly to raise earthworms without fermentation. The effect of raising earthworms will be better if rotten fruits, rotten vegetable leaves, etc. are mixed with cow dung.

First, pile the cow dung into a 2-meter-long, 1-meter-wide, and 35-cm-high (thick) pile. Use an iron rake to loosen the top cow dung every day. The cow dung that has been dried to 50% needs to be loosened to a thickness of about 5-8 cm. When it is about 50% dry, you can put in earthworms. Each pile of dung can contain 30,000 egg-laying earthworms. Collect the earthworm manure and cocoons every 10 days and open another pile for incubation. Take out the cocoons every 10 days and open another pile for incubation to ensure that the size and specifications of each batch of earthworms are consistent. During the breeding period, if the earthworm manure is found to be dry, spray EM water in time, and mix EM with clean water or rice washing water or rice soup in a ratio of 1:5 and spray. Generally, spray once every 3-5 days. The earthworms raised by the above method grow fast and produce more and larger cocoons. Note that poultry and livestock manure must be fermented with EM or dried in the sun and mixed with a water content of about 60% before it can be used to raise earthworms.

5. Can earthworms be raised by fermenting cow dung alone? How can the breeding be successful?

1. Cow dung is most easily absorbed by earthworms after fermentation. Professional earthworm farmers all do this (because the cost is low);

2. Earthworms like dark, moist, warm places with plenty of food.

3. This is baking powder. I really don’t know where to buy it (I can’t help you with this question! Haha)

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.
