CATDOLL : CATDOLL: Can you make money by breeding earthworms? Zhihu (Can you make money by breeding earthworms? Zhihu article)

1. What is the cost-profit cycle of earthworm farming?

1. Cost

(1) Planting earthworms: One acre of land requires 80 kilograms of planting earthworms. There are about 1,000 earthworms in one kilogram. The price of one kilogram is 300 yuan. The cost of 80 kilograms of planting earthworms is 24,000 yuan.

(2) Feed costs: One acre of earthworms requires about 20 tons of feed per year, which costs about 10,000 yuan.

(3) Land rental and labor costs: approximately RMB 15,000 per year.

(4) Total: about RMB 50,000 per mu per year.

2. Benefits

One acre of land can produce 8-12 tons of earthworms per year. The lowest market purchase price is 6 yuan per catty, so the annual income per acre is about 96,000 to 144,000 yuan.

3. Profit

After deducting costs from income, the annual profit per mu is about 46,000 to 96,000 yuan.

2. 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.

3. 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.

4. What are the costs and profits of raising ten acres of earthworms?

1. How much investment is needed to raise earthworms

1. The cost of earthworm farming ranges from 20,000 to 30,000 yuan per mu. The main costs include: earthworm seedlings, site rental, feed, water, electricity and labor costs. Although earthworms can be farmed indoors or outdoors, they are prone to death if the temperature is below 0°C or above 40°C, so try to farm them indoors.

2. Earthworms contain a lot of protein, amino acids, minerals and other nutrients, which have a good growth effect on chickens, ducks, loaches, eels, etc. Compared with concentrated feed, earthworms have a lower cost. For farmers, choosing earthworms as feed is a good method.

3. Earthworms contain defensins that can decompose toxic substances and activate heavy metal ions. Therefore, many cities are currently introducing earthworms in large numbers for the treatment of urban waste.

2. How much is the profit of raising earthworms per acre?

1. The annual yield of fresh earthworms per mu is about 2-3 tons, and can reach up to 5 tons. If calculated based on the minimum of 2 tons, the current market price is more than 10,000 yuan per ton. Based on the minimum of 10,000 yuan per ton, the income per mu can be 20,000 yuan. Excluding labor costs and other miscellaneous expenses, the profit of raising earthworms per mu is about 20,900 yuan.

2. There is no uniform price for earthworms. There are fluctuations every year, and the prices in different regions are also different. For example, fresh commercial earthworms are generally 5-8 yuan/jin, and seed earthworms are around 45 yuan/jin. Generally, 7-8 jin of fresh commercial earthworms can be dried to get one jin of dried earthworms.

3. The most suitable growth temperature for earthworms is 15℃-27℃. If the temperature is below 0℃ or above 32℃, the activity will become slow, the earthworms will stop eating, the mating movements will also become slow, and the reproductive process will not proceed. During the breeding process, you must pay attention to the temperature of the earthworms' living environment.

5. What are the costs and profits of raising 3 acres of earthworms?

The cost of earthworm farming per mu ranges from 20,000 to 30,000 yuan. The main input costs include: earthworm seedlings, site rental, feed, water and electricity, and labor costs. Although earthworms can be farmed indoors or outdoors, they are particularly prone to death if the temperature is below 0°C or above 40°C, so try to farm them indoors. The yield of fresh earthworms per mu is about 2-3 tons, and can reach up to 5 tons. If we calculate based on the minimum of 2 tons, the current market price is more than 10,000 yuan per ton. Based on the minimum of 10,000 yuan per ton, the income per mu can be 20,000 yuan. Excluding labor costs and other miscellaneous expenses, the profit of raising earthworms per mu is about 20,900 yuan.
