CATDOLL : CATDOLL: Feasibility report on earthworm farming (how much profit can be made from earthworm farming on 5 mu of land in a year)

1. Technology of breeding earthworms in wasteland?

Technical points of earthworm farming

1. Making earthworm beds.

Indoor breeding is divided into three types: pit breeding, box breeding and pot breeding. Generally, pit breeding is preferred. The size of the pit depends on the number of breeding and the indoor area. The pit is rectangular, with a depth of not less than 60 cm, half underground and half above the ground. The surroundings are built with bricks, and the bottom of the pit is smoothed with cement or solid soil.

2. Free range.

After the sludge is fished out, spread it out to dry, then mixed with 20% chopped rice straw, wheat straw and leaves and filled into the pit with a thickness of 20-25 cm. Maintain a humidity of 65% and evenly move the earthworms into the pit.

3. Management.

The suitable temperature for earthworms is 15℃-30℃. Water can be sprinkled to cool down in hot seasons. Outdoor breeding should not be exposed to the sun, and necessary sunshade facilities should be provided. When the temperature is below 12℃, cover with straw to keep warm and maintain 65% humidity. In addition, it is necessary to separate the piles frequently and raise large and small earthworms separately.

4. Prevent natural disasters.

Prevent damage from natural enemies such as rats, birds, chickens, and ants, and avoid damage from toxic substances such as pesticides.

5. Notes:

The breeding place should be protected from light and the soil in the bed should not be turned over at will to maintain a quiet environment.

2. What is the prospect of raising earthworms and are the benefits significant?

1 Raising earthworms has a good prospect and considerable benefits. 2 Earthworms are a good organic fertilizer maker, and their excrement can be directly applied to farmland as fertilizer. In addition, earthworms can also be used as feed for poultry and aquatic products. Due to the continuous improvement of environmental awareness in recent years, the demand for organic fertilizers has also been increasing, so the prospect of raising earthworms is very broad. 3 If you want to raise earthworms, you can choose to set up an earthworm farm at home or in farmland, or you can use it as a small entrepreneurial project. However, during the breeding process, you need to pay attention to the feeding and environmental conditions of earthworms to ensure their growth and reproduction.

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. How many kilograms of earthworms can be produced in one acre of land in a year?

The breeding cost is about 30,000 yuan per mu. The reproduction capacity of earthworms is very strong. Under normal breeding conditions, the annual output of earthworms per mu can reach about 3,000 kg, and high yield can reach 5,000 kg.

Based on the average output of 3,000 kg, the current market price is about 10 yuan/kg, so the output value of earthworms is about 30,000 yuan.

Among them, earthworm manure is also a fertilizer with a very wide range of applications. Generally, the output of one acre is about 40 tons, and the price is 150 yuan/ton, so earthworm manure can also be sold for 6,000 yuan. Therefore, the total profit of one acre of earthworms can reach 36,000 yuan.

5. How to breed earthworms?

1. Breeding methods: generally divided into three methods: ecological breeding, three-dimensional breeding and greenhouse breeding.

Ecological breeding includes arable land breeding, forest land breeding and trench breeding; three-dimensional breeding includes multi-layer cement frame breeding, overlapping breeding box breeding, tank breeding, louvered box breeding and nylon net bed frame breeding; greenhouse breeding is divided into greenhouse breeding and solar greenhouse breeding. Among them, arable land breeding and greenhouse breeding can grow crops such as grain, vegetables and fruit trees at the same time, killing two birds with one stone; three-dimensional breeding can obtain more earthworms; greenhouse breeding has a fast reproduction speed; ecological breeding and greenhouse breeding are low in cost and each has its own advantages. You can choose the breeding method according to your own breeding purpose.

2. Breeding pond setting.

Generally, the depth of the breeding box and ditch should be kept at 30-50 cm, not too deep. The width and length are not limited. It is advisable to use a site with convenient drainage and irrigation. Keep the filling material moist and prohibit water accumulation. You can fill it with decomposed cow dung, pig dung and other manure, or rotten leaves and forest soil. The surface can also be covered with a layer of farm soil.

3. Choose a suitable earthworm species and put in an appropriate amount of earthworm seed.

There are many varieties of earthworms, but they should be selected according to the purpose of breeding. For example, anglers like small earthworms, and if the earthworms are too thick, they will not work. The general price of earthworms is between 3-15 yuan, and 2-3 kilograms can be raised in 1 square meter. Generally, half an acre of land is needed to raise earthworms, and 700-900 kilograms can be raised. The number of earthworms should not be too large, otherwise it will cause the organic matter to be consumed too quickly, and the earthworms will escape after rapid reproduction.

4. The method of feeding.

The feed must be decomposed leaves, grass, fruit, vegetable leaves, kitchen scraps, manure, etc. In order to speed up the fermentation, urea, EM bacteria, etc. can be added for rapid fermentation, and then fish meal and bone meal can be added for feeding. The more times the earthworms are fed, the faster they grow and reproduce.

It is better to feed small amounts of bait multiple times. Generally, the remaining bait should be cleaned up once every 15 days or so. It should not be piled up for a long time, but the remaining bait should not be cleaned up all at once either, so that the earthworms can find their own holes, otherwise it will cause the earthworms to escape.

5. Effectively regulate temperature, humidity and light.

Earthworms are sensitive to temperature, humidity and light, and have very strict requirements. Earthworms prefer warm, humid and cool environments. The breeding site needs to be shaded as necessary, and only needs 2-3 hours of light a day at most. Earthworms grow well in an environment of 20-30℃. In the hot season, you can cover it with a layer of straw to reduce the temperature and increase the humidity; in the cold season, cover it with mulch, straw curtains, arch sheds, etc. to increase the temperature; in spring, summer and autumn, you need to maintain a high soil humidity, preferably without water accumulation. If the surface turns white, you need to spray or water it to ensure the normal growth and feeding of earthworms.

6. Collection method.

Indoor breeding generally uses strong light to drive away earthworms, and the earthworms will gather in the lower layer of the breeding bed or in the container under the screen. In the wild, the food trap method is generally used, and rotten fruits are put in. After 2-3 days, the earthworms will gather in the fruits.

6. How to breed earthworms in large quantities?

1. Planting seeds

After adjusting the humidity of the decomposed feed, spread it 10 cm along the trench dug in the mulberry garden, and then evenly put the eggs and young earthworms, and then put 5 cm of feed on it. The breeding density can be controlled at 2-2.5 kg/m2 or 10,000-15,000/m2. In principle, the density can be slightly higher in the early stage and gradually reduced in the later stage.

2. Shade and protection net

After the earthworm seeds are placed, a layer of plastic mosquito net is first covered on the ditch, and then plastic film, foam board and other rainproof materials are placed on it. This can prevent damage from rats, frogs, etc. and can also prevent rain and keep moisture.

3. Adjustment of temperature and humidity

The best breeding temperature for earthworms is 20-27℃, which is the same as the temperature requirement of silkworms.

In winter, the mulberry garden uses a thickened breeding bed to 40-50 cm, and the bait is covered with wheat straw or rice straw. The dead leaves of the mulberry trees and the cut mulberry branches can also be thickened and laid flat, and then covered with plastic cloth for heat preservation and moisture retention. In winter, when heating the greenhouse and silkworm room, it is necessary to pay attention to the smoke pipe of the stove.

To prevent maggots from getting gas poisoning, in addition, the relative humidity of the air should be maintained at 70%-80%, and ventilation should be carried out 3-4 times a day, 30 minutes each time. In summer, water once a day to cool down the plant in combination with ventilation. Generally, watering once a week is sufficient.

4. Frequent feeding

Remove earthworm castings, take out earthworm cocoons or turn over the feeding beds, and feed them 2-3 times a month, with a thickness of 10 cm each time. Keep the manure fresh and breathable to reduce the chance of earthworms becoming sick due to excessive accumulation of manure and untimely removal of earthworm castings, and create good conditions for the growth of earthworms.

5. Staged feeding

Earthworm breeding can be divided into seed group, breeding group and production group. Feed thinly and turn frequently. Feed twice a month, and the thickness of each feeding is 10 cm. Staged breeding is beneficial to the routine management of maggots, the reproduction and growth of earthworms, and the occurrence of diseases and insect pests.

6. Processing of earthworm cocoons and seeds

After 20 days of feeding, earthworms will produce a large number of cocoons through cross-breeding. At this time, the breeding earthworms and cocoons can be separated and hatched, and the separated cocoons, manure and earthworm manure mixture can be piled into a new breeding pile, maintaining good temperature and humidity.

When 50% of the earthworm cocoons are hatched, they can be covered with 10 cm of manure on the pile. They will be completely hatched in about 20 days. At this time, the density in the hatching pile is very high, and 50,000 to 60,000 cocoons can be hatched per 1 m2. They should be divided into piles in time and divided into 2-3 parts and covered with new manure for feeding. After routine management, they will all grow up in about 40 days.

The seeds separated from the breeding earthworms are re-mixed and fed with new manure. After 20 days, they can be bred again.

7. Harvest at the right time

The 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. Harvest once a month in summer, and once every 1.5 months in spring and autumn, and replenish feed in time after harvesting.

7. What are the technical methods for earthworm breeding?

It is best to raise earthworms in a large clay pot with some black soil and cow dung.

Maintain proper humidity. Just put the earthworms in. For feeding, it is recommended that you feed fruit peels. Apple peels and pear peels in winter, and watermelon peels in summer are good. Put the watermelon peels on the earthenware jar with the flesh facing down. After a few days, when you turn the watermelon peels over, you can clearly see the traces of earthworms eating them. Do not put citrus fruits or the like. The smell is irritating and the earthworms will all run away. In addition, earthworms fed with fruit peels have
