CATDOLL : CATDOLL: What bacteria are better for raising earthworms by fermenting cow dung? (What bacteria are better for raising earthworms by fermenting cow dung?)

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. How to ferment cow dung to breed earthworms?

1. Feed preparation:

Fermentation: Use rice straw or stalks to spread a 10-15 cm thick layer of dry material, and then spread 4-6 cm of manure on the dry material and repeat 3-5 layers. Use a spray bottle to spray water on each layer until the water seeps out. If garbage is used, pile up one layer of garbage and one layer of manure.

There is no limit to the length and width, and it should be covered tightly with a film. In the season with higher temperatures, it should be turned over every 7 days. Generally, the fermentation of the feed is completed after 3-5 times of turning over.

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; The scientific proportion of feed is the most effective way to increase the yield of cultured earthworms. 2. The above formula example requires:

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 manure 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.)

3. 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.

4. How to process dry cow dung to raise earthworms?

If you want to breed earthworms with cow dung, you need to ferment it. You can use Lebeifeng feces feed fermentation agent to ferment it. The fermentation method is very simple. Just mix the bacteria with cow dung evenly. If you want to breed earthworms, it is best to add some grass powder and straw powder. After mixing the raw materials, add water and pile them into a large pile for fermentation. Fermented cow dung breeding earthworms grow fast.
