CATDOLL : CATDOLL: Is it true that you can earn tens of millions of yuan a year by raising earthworms with cow dung? (Is it true that you can earn tens of millions of yuan a year by raising earthworms with cow dung or is it false?)

1. Can earthworms be raised with organic cow dung?

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.

2. How to breed earthworms with cow dung?

1. Feeding: timely feeding can promote the rapid growth of earthworms. The thickness of the manure should be 5-10 cm, and do not cover the bed completely.

2. Earthworm breeding temperature: 5-40℃. Thicken the bed to 40-50cm in winter, cover with straw and black film. Water every day in summer. Loosen the bed before adding manure to increase the air permeability of the earthworm bed, add 5-10cm of manure, harvest once a month in summer, harvest once every 1.5 months in spring and autumn, and replenish feed in time after harvesting.

3. Bait: The best baits are cow dung, pig dung, horse dung, sludge, rabbit dung, pig, sheep, rabbit dung plus straw.

5. Harvesting earthworms

Move the cow dung away, move the dense areas by hand, put the earthworms and soil into the basin, then pour it on the flower oil paper, spread it flat, and use the principle that earthworms are afraid of light to hang the soil layer by layer. What remains are the earthworms.

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 much is the profit per acre from raising earthworms in a greenhouse?

Annual investment expenditure of 1 mu of earthworms

1. Use 100 cubic meters of bait (cow dung, pig dung, chicken dung, and mushroom waste) at 20 yuan per cubic meter, for a total of 2,000 yuan.

2. 100 kg of self-bred earthworm seeds, with a cost of 20 yuan per kilogram, a total of 2,000 yuan.

3. The land occupation fee is 1 mu, 600 yuan per mu, totaling 600 yuan.

4. Plumbing and electrical tools cost RMB 500.

5. Total: RMB 5,100.

2. Annual income from raising 1 mu of earthworms

1. Earthworms: Generally, the annual yield of fresh earthworms per mu is 2 to 3 tons, and up to 5 tons. Based on the minimum of 2 tons, the current market price is more than 10,000 yuan per ton (it can be sold as bait for more than 30,000 yuan per ton). We calculate it based on the minimum of 10,000 yuan per ton, and can also earn 20,000 yuan.

2. Earthworm manure: 40 tons, 150 yuan per ton, totaling 6,000 yuan.

3. Total: RMB 26,000.

3. Net profit of raising 1 mu of earthworms

26,000 yuan - 5,100 yuan = 20,900 yuan. If you hire workers to carry out large-scale breeding, you also need to pay the workers' wages. Generally, one worker can manage two acres of earthworm breeding. If we calculate it based on a monthly salary of 1,000 yuan, we need to pay about 6,000 yuan per acre, and the actual profit is about 15,000 yuan.

Practice has proved that the manure produced by 30 cows per day can feed earthworms on one acre of land, and each acre can produce 2 to 3 tons of earthworms per year, 40 tons of earthworm manure, and can increase income by 15,000 yuan. Each cow can increase income by 500 yuan. In a county, if 15,000 cows can be used to breed earthworms, the income can be increased by more than 7 million yuan. It can form an industry and promote local economic development. It can increase the income of 2,000 farmers by nearly 4,000 yuan per household. The development of earthworm farming can drive the development of many industries such as cattle farming, pig farming, and chicken farming. Both sides promote each other and develop together.

5. Can you make money by raising earthworms?

Earthworm farming can make a small fortune. We can analyze it from three main aspects: breeding principles, survival rate and sales channels.

Earthworms are usually farmed using cow dung, sheep dung and other feces as raw materials. The breeding cost is very low. The feces consumed by earthworms is a good organic fertilizer that can obtain various economic benefits.

Secondly, earthworms are easy to raise, have a high survival rate, grow relatively fast, and have fast economic benefits. Finally, the sales channels of earthworms are getting wider and wider, and the market demand is getting bigger and bigger. From these points of view, raising earthworms is profitable.
