1. 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.

2. 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.

Total income: 26,000 yuan.

4. What are the prospects and sales of earthworm farming in 2021?

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.

Earthworms are high-quality protein feed. Earthworms contain a lot of protein, and the protein content in dry matter can be as high as about 70%. The general analysis results can also get 41.62-66% crude protein. It is reported that earthworm protein contains a lot of amino acids, which are necessary for the growth and development of livestock, poultry and fish. Among them, the highest content is leucine, followed by arginine and lysine. The arginine content in earthworm protein is twice that of peanut protein and three times that of fish protein; the tryptophan content is four times that of animal blood meal protein and seven times that of beef liver. Not only does the earthworm's body contain a lot of protein, but its feces also contain a certain amount of protein. The Japanese Food Analysis Center has analyzed earthworm manure. When the water content is only about 11%, the total nitrogen contained in the earthworm manure is about 3.6%, which is converted to 22.5% crude protein.

Earthworms are very supportive of environmental protection. Why do you say that? As we all know, earthworms have a strong digestive ability and can decompose a variety of organic matter and use it for themselves. Raising earthworms to deal with garbage has become an environmentally friendly way adopted by many developed countries. With the rapid development of modern industry and agriculture, many industrial wastes have been discharged, causing serious public hazards. The large-scale application of pesticides has polluted large tracts of farmland, and the human environment has been seriously polluted, directly affecting human health. Such environmental pollution problems have attracted international attention.

It is understood that breeding 330 million earthworms can process 100 tons of papermaking sludge every day. Japan uses earthworms to process up to 3,000 tons of these wastes per month, and the United States uses 500 million earthworms to process 200 tons of industrial waste every day. The number of earthworms required is huge, and it is conceivable how much breeding space there is for breeders to use. It not only drives economic development, but also effectively solves part of the problem of environmental pollution. Breeding earthworms is indeed a feasible breeding project.

Cooperation method: Joint cooperation

With the continuous development and utilization of artificially cultivated earthworm products, the market demand has increased dramatically, and the products are in short supply. In order to ensure the healthy development of my country's artificially cultivated earthworm industry, the products now need to be produced in large quantities, develop the domestic market, and enter the international market. Our factory has decided to jointly run a farm with qualified units and individuals and cooperate together.

Practice has proved that the manure produced by 30 cows per day can feed earthworms on one mu of land, and each mu can produce 3 tons of earthworms and 60 tons of earthworm manure per year, which 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 cattle farming, and both sides can promote each other and develop together.

What are the techniques for breeding earthworms?

(1) Outdoor places are most suitable for breeding earthworms. In this environment, earthworms have strong vitality and reproduce quickly. Indoors are generally suitable for small-scale breeding or breeding of newly hatched earthworms, because newly hatched earthworms are small in size and have a limited range of activities. If outdoor and indoor breeding are combined, good results will be achieved. The ideal location is preferably under a tree, where the shade is the coolest and can effectively reduce the earthworms from crawling out and escaping.

(2) The breeding bed is set up outdoors. When there is strong sunlight, hot wind, or rain, protective measures must be taken. It is best if there is a natural tree shade, otherwise artificial cover must be added.

In the hot summer, direct sunlight should not exceed 2 to 3 hours a day. This is because earthworms are sensitive to light. When exposed to strong light, they will stop eating and burrow into the ground. Therefore, using natural tree shades is better than using straw curtains, rags, straw, horse manure paper and other things on the breeding bed for protection.

The most suitable growth temperature for earthworms is 15℃～27℃. When the temperature is below 0℃ and above 32℃, the activity becomes slow, the earthworms stop eating, the mating action becomes slow, and basically the reproduction process does not proceed. When the temperature of the breeding bed is generally below 10℃ and above 27℃, it is difficult for earthworms to hatch. The most suitable humidity in the growth environment of earthworms is 60%～70%.

(3) Earthworms can grow and mature quickly after being fed with animal manure, grains, compost and other decayed organic matter. The selected feed should contain vitamins, minerals, proteins and other ingredients, which are essential nutrients for the growth and development of earthworms. Earthworms prefer sweet foods.

(4) Harvesting period of earthworms: generally, it is carried out when the adult rings are obvious, the growth and development are slow, and the feed utilization rate is reduced. Harvesting is done once a month in summer and once every 1.5 months in spring and autumn. Feed should be replenished in time after harvesting.

(5) The breeding earthworms should be renewed 2-3 times a year and the breeding beds should be replaced once a year to ensure the vigorous growth of the earthworms and prevent the decline of the population.

What are the main uses of earthworms?

1. Application of earthworms in aquaculture: Earthworms are an excellent animal protein feed for aquatic animals. Adding a certain amount of earthworms to aquaculture compound feed can produce high-quality and efficient feed. In this way, earthworms are not only high-quality feed, but also the most ideal feeding and growth-promoting substance, thereby improving the palatability of aquaculture objects to feed, increasing feeding intensity and feed utilization, and achieving cost saving, increased production, high quality and high efficiency.

2. Application of earthworms in animal husbandry: ① Replace fish meal. The protein content in earthworms is equivalent to that of imported fish meal and higher than that of domestic fish meal. It can replace fish meal as a protein feed for farmed animals. Fu Guiyu's test results show that feeding fattening pigs with earthworm meal instead of fish meal can increase the daily weight gain by 13.1% and reduce the feed-to-weight ratio by 10.0%.

② Growth promotion and disease prevention and disease resistance Earthworms are widely used in the animal husbandry industry because of their rich nutrition, disease resistance, health care and feeding effects. Earthworms can be used to treat high fever in pigs, chronic emphysema in cattle and horses, urethral stones in cattle, white (yellow) diarrhea in piglets and many other animal diseases, and have a good disease resistance and health care effect.

5. 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.
