CATDOLL : CATDOLL: Where is it suitable to breed Golden Edge Earthworms?

1. Where is the best place to breed Phnom Penh Earthworms?

The Golden-edged Earthworm is a species unique to the south, most of which are distributed in Guangdong, Guangxi and Fujian. It is highly dependent on the environment, especially if the temperature and humidity are not well controlled, it may cause a large number of deaths. It is not recommended to raise it in the north.

Earthworm breeding technology

1. Breeding form

Earthworms have strong vitality. As long as they are not exposed to the outdoors, wind, rain, or direct sunlight, they can survive. Loose soil and a dark and humid environment can make earthworms grow well. Here are some ways to grow them:

1. Pot culture

You can choose a plastic pot with a smooth inner wall, which is more than 15 cm in height and 45-60 cm in diameter, and can be directly raised with soil built in. Pot breeding is suitable for small-scale breeding, with small investment, easy operation and flexible movement.

2. Tank culture

Choose a clay pot with a smooth inner wall, the height of the pot should not exceed 1 meter, and half or part of it should be buried underground. The breeding soil can be placed 40-50 cm thick, the underground temperature and humidity are balanced and stable, the earthworms grow well, have a long life, and have good output quality.

3. Pond culture

Flat pool culture is the predecessor of three-dimensional greenhouse culture pool. Use bricks to build a square or rectangular pool with a height of 40-50 cm on the indoor cement floor, leaving a 1-meter walkway, build pools on both sides or build the entire room with pools, and lay wooden boards on top for walking and operation. When painting the upper edge of the inner wall of the pool, use cement slurry to stick 6-8 cm glass strips (thick film can be used instead if there is no glass strip) to prevent earthworms from rolling over. This method of cultivating earthworms grows well, is easy to manage and requires little investment.

4. Three-dimensional feeding

What we advocate now is the more advanced greenhouse three-dimensional breeding model. The requirements for building a three-dimensional breeding pool are that the house should not leak, the surrounding walls should be intact, and a flat roof house is fine. Leave doors and windows around the house, and use vertical bricks to build a partition wall, with a gap of 5-10 cm from the original wall. When building the partition wall, use top bricks to support the original old wall at intervals. In order to prevent the partition wall from collapsing, the function of the partition wall is to keep warm and moisturize, which is of great significance for breeding earthworms. After the partition wall is built, leave a walkway of 0.95-1 meter according to the remaining area in the house, design the size of the breeding earthworm board, the thickness of the breeding earthworm board is 3-3.5 cm, and after the size is determined, it is poured with reinforced concrete. After the earthworm board is poured and maintained, the three-dimensional earthworm pool can be built. There are 3 vertical bricks per layer (about 40 cm high). After one layer is built, the inner wall is painted and another layer of earthworm board is laid. It can be built 6-7 layers, and the top is capped. Leave a 19-20 cm operating window on one side of the walkway of the earthworm room, and stick a hard plastic paper about 4 cm extending into the earthworm pool on the upper edge of the operating window to prevent earthworms from running away. After the earthworm room is built, paint the surrounding inner walls and fill in the gaps to prevent rats and ants from entering. 5. Heating breeding Heating breeding is particularly important in the process of artificially raising earthworms. Heating the breeding pond can shorten the growth cycle by one third. Although heating increases some costs, the benefits generated are insignificant in comparison. The heating method can also be adopted according to local conditions.

Golden-edged earthworms are a species unique to the south, mostly distributed in Guangdong, Guangxi, and Fujian. They are highly dependent on the environment, especially if the temperature and humidity are not well controlled, they may cause a large number of deaths. It is not recommended to raise them in the north. Even in the south, there are only a few who can be considered to have successfully raised them, let alone large-scale breeding. Since the cost of golden-edged breeding insects is too high, it is recommended that novices buy about 30 kilograms to try first, master the technology first, and then expand investment. Otherwise, blind investment may lead to bankruptcy overnight.

Adjust the temperature and humidity to the same level, the temperature is between 20-29 degrees

3. What are the breeding conditions for earthworms?

Living habits of earthworms:

The earthworm is an important medicinal insect. It lives in dark, moist, humus-rich loose soil. It is afraid of sunlight, hides during the day and moves at night. The most suitable temperature for its growth is 28-30℃. Temperatures below 0℃ or above 38℃ will cause a large number of deaths of adults and nymphs. When the temperature drops to 8℃, it stops moving and enters a dormant period. The earthworm needs to go through three stages: egg, nymph and adult to complete a generation. It takes about 8 months for male insects to grow wings from nymphs, while female insects are wingless and mature in about 9-11 months. Male insects die 5-7 days after mating. Female insects can lay eggs one week after mating, and they will lay eggs for the rest of their lives after mating. The source of earthworm food varieties: Earthworms are omnivorous insects. Among their feeding characteristics, they like to eat fresh food. They like bran and rice bran the most, followed by cornmeal, broken grains, peanut cakes, soybean meal, miscellaneous fish, meat, and various grass and vegetable leaves, melon and fruit peels, chicken, cow dung and other coarse materials. If only grass and other feeds are used for feeding, the growth rate will be slow. The complete feed can be 72% wheat bran, 20% cornmeal, 5% bean cake, and 3% animal feed (cooked feed). When feeding, use boiling water to scald, and add 30% to 40% green vegetables or fruits. After 5 to 6 months of feeding with complete feed, the individual can grow into an adult. The body structure of earthworms The adult earthworm mother is about 3.4 cm long and 2 cm wide. The body is oval, some earthworms have gray backs, some earthworms have white backs, flat up and down, brown-red chest, small head hidden in the prothorax, with a pair of antennae and a pair of more developed compound eyes. Chewing mouthparts, with transverse sections on the back, arranged in a shingle-like manner, 3 pairs of feet on the chest, 2 pairs of wings, which are more developed. The forewings are leathery, and the hind wings are membranous and translucent, folded on the back. They have the ability to fly short distances, and can fly up to 5 to 6 meters from top to bottom, and have a pair of tail whiskers. After mating between male and female earthworms, they lay eggs that resemble rice grains. It is 1 to 1.5 times larger than rice, about one centimeter long, and brown-red in color. There are longitudinal stripes on the surface of the egg mass. Each longitudinal stripe has a larva, arranged in two rows, and one egg mass contains 8 to 16 larvae. How to control temperature and humidity in earthworm breeding? The following methods can be used to control temperature and humidity: (1) Heating: When the required temperature cannot be reached in the breeding environment, a stove can be used to increase the indoor temperature and increase the local temperature of the pit or pool. (2) Cooling: If the temperature in the pit or pool exceeds the suitable temperature for the earthworm in summer, water can be sprinkled on the indoor ground, ventilation can be strengthened indoors and in the pit or pool, exhaust fans can be installed, or water basins and ice trays can be added to the pit or pool. If the temperature continues to be high and dead insects are found, they should be screened in time to screen out old nymphs or some adults, and used as medicine after processing to reduce the insect population density in the pit or pool and reduce the amount of food. (3) Humidification: When the humidity in the breeding grounds, pits or pools is lower than 15%, spraying and ground sprinkling should be used, and items with large evaporation surfaces after absorbing water, such as absorbent soft foam boards, cotton fiber fabrics, soaked clothes and quilts, should be hung in the corners of the pits and pools to dissipate moisture. (4) Dehumidification: When the humidity in the pits and pools exceeds 30%, dehumidification measures should be taken in time, such as opening doors and windows and exhaust fans to enhance ventilation. If the outdoor atmospheric humidity is too high and continues to rise, calcium chloride wooden boxes and quicklime boxes should be placed in the corners of the pits and pools to achieve the purpose of local dehumidification.

1. The living habits of earthworms.

Earthworms are suitable for living in dark, moist, loose humus soil. In the wild, earthworms live in humus soil and gravel under kitchens, corners, and deciduous trees. They can burrow into the soil to a depth of 0.5 to 0.6 meters. They rest in the soil during the day and move around, forage, and mate after dusk. Earthworms are omnivorous insects with a wide range of diets. In addition to a small amount of concentrated feed, most of their feed is wheat bran, fine bran, and green fodder. They also eat various grains, animal residues, feces, etc.

2. Hatching of earthworm eggs.

Spring is the best time for earthworms to lay eggs and breed offspring. Choose a plastic basin with a smooth inner wall and a diameter of 50 to 80 cm, place 4 kg of eggs in the basin, mix in breeding soil that accounts for 1/2 of the volume of the eggs, and keep the humidity of the breeding soil at 40% (it is required to be grasped into a ball by hand and fall freely). The thickness of the basin with eggs and soil is 8 to 10 cm. The breeding soil should be prepared in advance and placed in the incubator for preheating. The temperature difference cannot exceed 5°C. During the incubation period, the temperature should be maintained at 25 to 30°C (the incubation temperature is preferably 28°C). Turn the eggs by hand 2 to 3 times a day. When turning, the movement should be gentle to avoid damaging the eggs of earthworms. After 35 to 40 days of incubation, a large number of larvae will break out of the shells. At this time, the larvae can be sieved out (using a 4 mm sieve). The sieved eggs are mixed with breeding soil again, and the sieved larvae can be placed in a pool with 10 cm thick breeding soil for breeding. The larvae are sieved every two days.

Note: The feeding soil can be the topsoil from the vegetable garden, sieved with a 4mm sieve, and then mixed with 50% burnt rice husk (rice husk) ash. If you add some livestock manure or crushed crop straw and sawdust to make the feeding soil more fertile and loose, the effect will be better. The standard for the humidity of the feeding soil is that it can be grasped by hand and will break into pieces when it falls freely.

Diseases and pests of earthworms and their control.

As a small non-toxic insect-like animal, earthworms have many natural enemies. The fact that they can survive and reproduce to this day shows that they have a certain ability to avoid enemies and prevent diseases. However, some diseases and insect pests are also very lethal to them, such as mites and enteritis, which sometimes even cause them to die in large numbers. In the process of artificial breeding, the prevention and control of diseases and insect pests of earthworms is an important task that must be done on a daily basis. The diseases that often occur in earthworms are mainly physiological diseases, fungal diseases and nematode diseases; the main insect pests are ants, and the harm of other animals includes mites, spiders, house mice, geckos, toads, scorpions, chickens, ducks, cats, etc. Since artificially bred earthworms are raised in groups at a high density, once the harm of harmful organisms occurs, it will cause great losses, and sometimes even the whole army will be wiped out. Therefore, in prevention and control, we should grasp the principles of prevention first, prevention over treatment, and timely treatment.

(1) Mites

①Because mites are active in the 1-2 cm area on the surface of the breeding soil, you can dig out the surface soil with mites and sift it out with window screens.

② After soaking the bran, make it into small balls with a diameter of 1 to 2 cm. Place them on the surface of the breeding soil at 3 to 5 points during the day, and the mites will flock to them. After 1 to 2 hours, remove the bran balls and the mites together. Repeated trapping can remove more than 70% of the mites.

③ Combine the above methods and do not feed for 1 to 2 days. The mites will die of starvation, but the earthworms will not be affected in their growth.

(2) Big belly disease

① Add antibacterial drugs, add 5 grams of oxytetracycline to 100 kg of feed or add 100 grams of berberine powder or garlic to 100 kg of feed, and feed for 3 consecutive days.

② Add 1 gram of yeast or 2 tablets of motherwort and 1 gram of complex vitamin B per kilogram of feed, feed once a day for 3 consecutive days, which has a good effect on eliminating abdominal distension and promoting appetite.

In addition, you should pay attention to adjusting the humidity of the breeding soil, feeding at regular times and in fixed quantities, and the feed should be reasonably matched. Do not feed a certain kind of feed for a long time.

(3) Natural enemies

There are many natural enemies of earthworms, such as rats, ants, spiders, chickens, ducks, cats, etc. The breeding pool should be sealed to prevent the entry of natural enemies. The new drug Cockroach Ant Net can be used to prevent and control ants, and the spider can be vacuumed once a week.

(4) Pesticides

When feeding earthworms, be sure to prevent pesticides from contaminating the feed. Mosquito-repellent incense and pest control spirits can also be fatal to earthworms and should be strictly prohibited.

Harvesting earthworms.

Three months after Chinese earthworms lay eggs, their peak spawning period has passed, and there will be a large number of deaths on the surface of the breeding pond. Choose a sunny day to harvest a large number of them at one time. The method is: use a 1 cm mesh sieve to dig the earthworms out of the pond with the soil and then sieve out the soil. Put the sieved earthworms into boiling water to kill them, rinse them and put them in the sun to dry. If it is a rainy day, use the drying method. To check whether the earthworms are dry, just squeeze the abdomen of the earthworm with your hands. If there is no soft material in the abdomen, it is a dry earthworm. The dryness rate of earthworms is 43%. Dried earthworms can be sold. The quality requirements are large, dry, free of impurities, and not moldy.
