CATDOLL : CATDOLL: How often should earthworms be fed (how often should earthworms be fed)

1. How much feed does one pound of earthworms eat in a month?

One pound of earthworms can produce about 2 pounds of feed per month.

2. How many kilograms of earthworms can be raised with one kilogram of cow dung?

3 kg per square

There are four key points in the breeding technology of earthworms raised with cow dung. The first is the feed formula. When feeding, 50% cow dung can be mixed with other feces to feed earthworms; the second is feed fermentation. Use straw and stalks to spread a layer of dry material with a thickness of about 10-15 cm for fermentation; the third point is feed modulation. After the feed is fermented, the pH value can be tested; the fourth point is breeding density. The number of earthworms raised with cow dung should be controlled within 10,000 per square meter.

1. Cow dung earthworm breeding technology

1. Feed formula: When feeding, use 50% cow dung, 50% pulp sludge, or 20% each of cow dung, pig dung, chicken dung, and 40% rice straw to feed the earthworms. Chicken manure must be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will escape or die.

2. Feed fermentation: Use straw to spread a layer of dry material with a thickness of about 10-15 cm, and then spread 4 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. In high temperature weather, you can turn it over every 7 days. Generally, the feed fermentation work is completed after turning it over 3-5 times.

3. Feed preparation: After the feed is fermented, the pH value can be tested. The suitable pH value of earthworm feed is generally 6-7.5, but the pH value of many animal and plant wastes will be higher or lower than this value. If the pH exceeds 9, acetic acid, salt or citric acid can be used as a buffer.

4. Breeding density: The number of earthworms raised in cow dung should be controlled within 10,000 per square meter. The production earthworm population of 3 kg per square meter is about 20,000 to 31,000. In the early stage, the number of young earthworms can reach 30,000 per square meter, but in the later stage of breeding, it must be reduced to 20,000.

3. How many days after making the vermicompost bed can you add earthworms?

After three days, the earthworm manure is laid out and ready to go, right? The earthworms are put in for breeding. At this time, the poor are very comfortable living in this environment. As long as we feed them some earthworms every day, special feed or other fruit food, the earthworms are very active in this environment and grow very fast.

4. What kind of feed should be used to feed domestic earthworms?

1. Earthworms eat the roots of rotten plants. Earthworms are omnivorous animals and do not eat anything except glass, plastic, metal and rubber.

2. It eats the rest, such as humus, animal feces, soil bacteria, and the decomposition products of these substances.

3. To feed earthworms, you only need to fill a large container with 3/4 fertile soil and a few vegetable leaves, and cover the container with a wet cloth.

4. If you want to raise earthworms on a large scale, it is better to use outdoor breeding methods.

5. How much protein feed is needed for breeding earthworms?

Earthworms are a high-protein feed, containing 55% to 60% crude protein in their dry matter.

6. How to breed large earthworms?

Living habits of earthworms

1. Likes the temperature: 15℃-25℃ is the best temperature. In order to create the best temperature, cover the greenhouse with plastic or plastic sheet in winter, cover with straw in summer, sprinkle water to cool down, hibernate at 0℃-5℃, freeze to death below 0℃, die above 40℃, and stop growing above 32℃. In Beijing, cover the greenhouse and plastic sheet on October 25th, and remove it on April 10th of the following year. In this way, the earthworms will grow to December 20th, and then to February 10th of the following year, they are basically dormant. From February, prevent the earthworms from escaping due to high temperature. Pay attention to uncover the plastic sheet in time after 10 days and gradually turn to the optimal temperature. At this time, pay special attention to high temperature days. This is the most difficult time. During the day, uncover the plastic sheet around the plant, cover it in the morning and evening, and water it in time to keep it moist. From March to June 10 is the peak period of spring spawning for earthworms. During the high temperature period, you should prevent heatstroke and cool down. It is best to water it once a day. From August 20 to June 10 to August 20 is the summer season, and the plant will gradually enter dormancy. At the end of September, it is the second peak period of spawning for earthworms.

2. Like moisture and afraid of dryness: The water content in the body of earthworms is about 80%, and the water content of bait is required to be 60%-80% (based on the water dripping from the fingers when holding the bait in the hand). Therefore, the moisture content of the breeding bed is required to be above 60%. In this way, water must be poured once a day or every 1-2 days. The water should not be too much, but it must be poured thoroughly and connected to the lower layer of material. The watering time is noon in winter, evening in summer, and daytime in spring and autumn.

3. Like darkness and afraid of light: earthworms hide during the day and come out at night. They can be seen foraging under the moonlight. The breeding bed should be covered with straw to keep it moist and shaded.

4. They like air and quietness. Loose bait is good for the growth of earthworms. Our experience over the years is to turn the bed over (about 20 cm thick) before feeding to increase ventilation. This is very important. Over the years, we have found that there are very few earthworms at the bottom of the bed soil, but there are still baits. The main reason is the lack of air, which is not good for the growth of earthworms.

2. Breeding methods

1. Breeding varieties: The "Daping No. 2" earthworm introduced from Japan is characterized by high reproduction rate, annual proliferation of more than 200 times, good settlement, heat and cold resistance, suitable for production all year round, and high yield of earthworm body and earthworm feces.

2. Breeding method: We have been adhering to open-air composting breeding for ten years since the establishment of the farm. I believe that this method is low-cost and is the best method for large-scale production of earthworm products. It does not require any investment in equipment and can make use of all idle land. As long as the unfermented cow dung, horse dung, and pig dung are made into 15-20 cm high, 1-1.5 meters wide, and unlimited length, and earthworm seeds are put in, covered with straw, and shaded and moisturized, then breeding can be carried out. We started breeding from a few square meters, and until now, this method has been used for the expansion of more than 200 acres of land. Its advantages are easy operation, eliminating a series of work such as composting and fermentation, and the bait keeps nutrients from being lost, which increases the growth rate of earthworms and is easy to promote and apply in rural areas. This method also has its disadvantages: once the bait is heated, the earthworms die and the corpses are not seen. In summer, after continuous rainy days and heavy rains, the bed is not breathable and there is a phenomenon of escape. The way to avoid this is to have new bait in each breeding bed. The bait is piled in blocks to create good bottom-up conditions for earthworms. The key to this method is to keep the moisture content of the bait at 60-70%. It should not be too dry or too wet, otherwise the bait will heat up and cause death.

7. Is it okay to feed earthworms with rice?

Can

There is no need to ferment rice when feeding it to red earthworms, as earthworms are omnivorous animals.

Earthworm life habits

1. Like darkness:

Earthworms are nocturnal animals. They hibernate in soil caves during the day and go out at night. They are usually active from 8 pm to 4 am the next morning in summer and autumn. They feed and mate in the dark.

2. Like moisture: Natural terrestrial earthworms generally like to live in moist, loose soil rich in organic matter, especially in fertile gardens, vegetable gardens, cultivated land, ditches, rivers, ponds, channels, as well as sewers near canteens, garbage dumps, under water tanks, etc.

3. Like quiet: Earthworms like a quiet environment. Earthworms living around industrial and mining areas often grow poorly or escape.

4. Like warmth: Although earthworms are distributed worldwide, they prefer relatively high temperatures. They will stop growing and developing at temperatures below 8°C. The optimum temperature for reproduction is 22-26°C.

5. Like sweet and sour food: Earthworms are omnivores. They do not eat glass, plastic and rubber, but eat everything else, such as humus, animal feces, soil bacteria, fungi, and the decomposition products of these substances. Earthworms have a keen sense of taste and like sweet and sour food. They hate bitter food. They like to heat and soften soft feed, and are particularly greedy for animal food. They eat a daily amount equivalent to their own weight. About half of the food passes through the digestive tract and is excreted as feces.

6. Prefer to live alone: ​​Earthworms have the habit of not wanting to live together with their offspring. Especially in high-density environments, if the young ones reproduce too much, the old ones will run away and move away.

8. 100 earthworm breeding methods?

Answer: 100 ways to breed earthworms:

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.

9. How often should toothfish be fed?

Toothfish is a niche ornamental fish. It is not difficult to breed them. However, due to their ferocious temperament, special attention needs to be paid when breeding them. Mixed breeding is possible, but single breeding is generally recommended. Because their temperament is unstable, they may hurt other weak fish species.

They are very protective of their food. They are carnivorous animals. They generally like to catch small fish, shrimps, earthworms and other animals. It is recommended to feed them with special artificial feed live bait. Feed once every 1-2 days
