How to prepare soil for earthworm breeding? What to prepare? What kind of soil is good?

The earthworm hides in the soil during the day and comes out at night to look for food and mate. Therefore, when it is artificially raised, the breeding soil (or pond soil) is the primary condition for the survival of the earthworm. It not only spends its entire life in the breeding soil, but also absorbs part of the humus, minerals and vitamins from the breeding soil. Therefore, the relationship between the breeding soil and the earthworm is very close. The quality of the breeding soil directly affects the growth and reproduction of the earthworm, so the breeding soil should be carefully prepared when it is artificially raised.

Spread the slag in the sun for disinfection, and keep turning and crushing it. After drying, sieve it with a sieve with a mesh size of 2.0-2.5 mm, and take the loose fine particles for later use. Spread the slag in the sun for disinfection, and keep turning and crushing it. After drying, sieve it with a sieve with a mesh size of 2.0-2.5 mm, remove the large particles such as stones, and take the loose fine particles for later use.

The two kinds of fine particles treated above are piled together and mixed evenly, and then water is added to adjust the humidity to about 20% before use. The breeding soil treated above has good physical properties, looseness, small particles, uniform size, light weight, and no compaction, which provides good conditions for the growth and reproduction of earthworms.

The quality of the feeding soil is the key to the success of breeding. Therefore, it is best to use 70% of odorless poplar and tung sawdust and 30% of loose and fertile soil rich in humus to prepare the feeding soil. Sawdust can make the feeding soil loose and permeable, which is convenient for earthworms to move. After mixing and sieving, spray it with water, pile it up and ferment it for 1 week before use. The humidity should be such that it can be held in a ball, loosen and feel damp. The thickness of the soil in the pond should be about 5 cm. The feeding soil should be replaced 1 to 2 times a year.

This is what I learned when I was raising it, and I'm sharing it with you.

Does the artificial breeding of earthworms have any requirements for geographical, climatic and soil conditions?

Earthworm (earthworm), also known as earthworm, earthworm, etc., is cold in nature, salty in taste, poisonous, and has the functions of promoting lactation, removing blood stasis, and relieving pain. It is an important Chinese medicinal material. Earthworm breeding technology-------------------------------------------------------------------------------- Introduction to earthworm breeding: Earthworms like to grow in dark, moist and soft soil, like a quiet environment without direct sunlight, and are mostly hidden during the day and come out at night. Generally, they come out to forage, move, and mate from 6 to 11 pm. It has high medicinal value and is mainly used to set bones and tendons, promote blood circulation and remove blood stasis, bruises, and reduce swelling and relieve pain. At present, exquisite foods made from earthworms have become popular in Europe and the United States. There is no need for special conditions to breed earthworms, and the management is relatively extensive. They can be raised in ordinary idle houses, basements, balconies, and plastic greenhouses. A house of 15 square meters can raise two groups of earthworm eggs. Its growth cycle is 8 months. Under normal circumstances, it can grow and develop above 20 degrees Celsius. The best temperature is 25 to 35 degrees Celsius. It will hibernate if it is below 13 degrees Celsius, and will freeze to death if it is below 0 degrees Celsius. The humidity of the space during the breeding process is 75% to 80%, and the humidity of the breeding soil is about 15%. Under normal circumstances, the breeding soil for larvae is slightly dry. As the worms grow up, the humidity gradually increases. As long as a certain temperature and humidity are reached, it can be raised all over the country. The staple food of earthworms is mainly wheat bran, supplemented with cornmeal, roughage, and various vegetables, leaves, fruit peels, etc. It can basically eat anything that chickens eat. Watermelon peel in summer, pumpkin and carrot in winter are all its top feed. Earthworms mainly grow in a built cement pool. The height between each layer of the pool is 40 cm. Glass strips or plastic strips should be attached to the edges to prevent escape. They can also be raised in plastic pots. It is best to keep them in plastic pots during the incubation period and before the fourth instar, which is convenient for management. The soil used for feeding is mainly log sawdust, with 30% of soft humus soil and a small amount of sand, and it is filtered with a sieve with a pore size of 3-4 mm. The thickness of the feeding soil (including egg blocks) during hatching is 12-15 cm, and the thickness of the larvae is 5-6 cm. The thickness of the soil for medium-sized worms is 11 cm, and the thickness of the soil for egg-laying worms is 15-17 cm. When feeding larvae, a feeding table can be used, and medium-sized worms can be directly and evenly sprinkled on the surface of the feeding soil. Pay attention to the feeding amount, how much you eat, how much you feed, and there should be no residual food to prevent the production of mites. After 11-13 months of feeding, the peak egg-laying period of earthworms has passed, and the weight of the female worms begins to decrease. And gradually die, then you can choose a sunny day, use a sieve with a pore size of 8 mm to screen out the earthworms, put them in boiling water to scald them to death, rinse them clean, and dry them in the hot sun for 3-5 days. If it is rainy, you should consider drying, and its dryness rate is about 40%. All breeders who come to our place to introduce species can visit the breeding base for free. Free breeding technical information, introduce species on the same day, learn on the same day, introducers do not need to prepare tools, there is no strict requirement for the number of species to introduce, and it can be determined according to their own conditions. At home, you only need to prepare breeding soil and plastic pots. Each group of 7-8 plastic pots can be used for 3-4 months. Eight major matters should be noted before purchasing seeds: At present, there is more or less speculation in the special breeding industry. Some rely on fancy advertisements to attract people; some use the brand of the origin of the variety to cheat people; some use "shell companies" to play guerrilla warfare to cheat people; some use the reputation of scientific research departments to cheat people; and so on. In order to ensure the interests of breeders and their due sense of responsibility, this center specially proposes the following suggestions to breeders to prevent being deceived. First, you must really understand the background of the seed supply unit, verify the business license, see its strength and breeding scale, whether it has recycling capabilities, and whether the recycling contract has been signed for more than two years. If conditions permit, you can inspect more companies. Second, a large amount of market research and analysis should be carried out. The overall sales of earthworms. The development prospects and economic benefits should be clarified one by one. 3. Ask more questions during the inspection so as to detect the strength, loopholes in breeding technology and other aspects, and compare the actual situation of each family. Select the best and eliminate the worst. 4. Analyze and observe the source and quality of seeds, seed production, seed storage and other aspects in detail, and avoid introducing species directly to the breeder. 5. Don't introduce species blindly. You need to master some theoretical knowledge first, visit the site, and introduce species only after mastering certain techniques. 6. Pay attention to the first introduction of species should not be too much, generally not more than 5 groups (except for large-scale breeding), and gradually increase the number in batches after the technology is passed. 7. There should not be too many breeding varieties. Too many varieties will disperse your energy; second, investment will not be concentrated and cannot be scaled up; third, management is inconvenient; fourth, they will affect each other and are easy to spread diseases. 8. When inspecting a project, select several varieties for comparison, analyze and compare them in advance from the perspectives of development prospects, market conditions, economic benefits, management technology level, etc., and finally determine that you should not easily start a project or give up easily. There are six major living habits that need to be mastered when raising earthworms: During the entire growth process, earthworms mainly prefer dark, humid, and soft soil places. They have the following six major living habits: First, they are non-social. Earthworms have no family distinction and will not kill each other because they do not grow together. Under reasonable density, earthworms of all ages can grow quietly and harmoniously. Second, they are soil-dwelling. Earthworms like dark, humid, humus-rich, and loose soils. They do not like direct sunlight and cold climates. Third, they are incomplete metamorphosis. Earthworms go through three stages in their life: eggs, nymphs, and adults. Fourth, they are omnivorous. Earthworms have a wide range of food, which can be divided into three types: refined, coarse, and green. Refined feed includes cakes, fish bone meal, meat, and animal scraps; coarse feed includes wheat bran, corn, rice bran, etc.; green feed includes various vegetables, fruits, and edible plant leaves. Fifth, they are negatively phototropic. Earthworms are afraid of light and like to hide during the day and come out at night. They lurk in the breeding soil during the day and come out at night to forage and mate. Sixth, they are temperature-changing. The growth of earthworms is greatly affected by temperature. It takes one and a half to two years for earthworms in the wild to complete a generation. When the temperature rises to 13 degrees Celsius in early April each year, they begin to emerge from the ground one after another, and the peak period of activity is from mid-May to late October. They enter a dormant state when the temperature drops below 15 degrees Celsius in late November. Artificial breeding adopts temperature control and ripening to prevent them from dormancy, and coupled with a sufficient and reasonable supply of food, a generation can be completed in 7-8 months. To breed earthworms, you must master eight key technologies: Although earthworm breeding is very simple, you cannot be too careless in actual breeding. All living animals will die once they are not noticed. However, there are some serious and some serious problems in comparison. The following key issues should be paid attention to when breeding earthworms: First, build a good breeding pool: First, you must choose a good house, the indoor thermal insulation performance should be good, the ventilation performance should be good, and the heating facilities in winter should be considered. The construction of the pool should be flexible according to the area of ​​the house. Under normal circumstances, a 1-meter-wide walkway must be reserved for management. The width of the pool is preferably one meter. If it is managed on both sides, a 2-meter-wide pool can be built. The bottom pool is 50 cm high, and each layer on the top is 40-45 cm high. The number of layers can be determined according to the height of the house. Anti-escape measures should be added to the edge of the pool. Glass strips or plastic strips can be pasted. The indoor environment should prevent the invasion of natural enemies and rainwater. Second, choose the breeding soil: the requirements for breeding soil are looseness, moisture retention, and good thermal insulation performance. Generally, it is best to use log sawdust with 30% of soft and non-sticky leaf humus. It should not be polluted by pesticides and fertilizers. It should be sieved into fine soil with a sieve with an aperture of 3 mm. The humidity of the soil is controlled by squeezing it into a ball, and it will fall apart when you let go. Third, hatching of egg masses: the quality of egg masses is good if the grains are full, the color is brown-red, and there are no impurities. Normal eggshells have 6-16 seeds. When hatching, mix the eggs and soil in a ratio of 1:1 (volume) and put them in a basin with a thickness of 12-15 cm. Keep the temperature at 27-30 degrees and the soil humidity at about 15%. Turn it over once in the morning and evening every day to adjust the dryness and humidity and the air permeability of the egg sheath. Keep the humidity of the indoor space at 75-80%. The eggs will hatch in about 45 days. Remember not to spray water directly into the egg mass. Fourth, feeding management: After the nymphs are hatched, use a sieve with a pore size of 4 mm to sieve out the nymphs, and then put them in a plastic basin. They can be fed after 4-5 days. The nymphs are mainly concentrated feed. They can be fed with boiled egg yolks and wheat bran heated with boiling water. They can also be fed with biscuits or bread crumbs mixed with a small amount of green feed (preferably sweet). Feed once every night. It is best to feed with a food tray. There should be no residual feed. Pay attention to the reasonable combination of concentrated, coarse and green feed during the egg-laying period. Fifth, timely separation of ponds: earthworms grow very fast in a suitable environment. Each time they shed their skin, their volume and weight will double. If they are not separated in time, it will affect their growth. When the density is too high, earthworms will climb up the four walls. If you hit the surface of the soil with your hand, it will rise and fall like waves. At this time, the ponds should be separated. Sixth, timely selection of male insects: male insects mature one month earlier than female insects, while female insects are still immature and cannot mate at this time, which will affect the normal growth of female insects. Male insects that have emerged should be picked out in time. After picking them out, they should be scalded to death with boiling water, their wings should be removed, and then boiled with light salt water for a while, the water should be purged, and then put in the refrigerator to make delicious food. This is more efficient than picking male insects before they emerge. After picking them out for one month, they can be allowed to mate on their own. One male insect can mate with more than 10 female insects. Male insects will die more than 20 days after mating. Before they die, they can be picked out and made into food. In this way, the male insects will be used. Seventh, egg mass screening: female insects begin to lay eggs one week after mating. The eggs laid drag on the tail for about 2 days and then automatically fall off into the soil. When collecting eggs, first use an 8 mm sieve to screen out the adult insects, and then use a 4 mm sieve to screen out the egg mass. The screening time is preferably 15-20 days. Eighth, processing of dried products: use an 8 mm sieve to screen out the aged adult insects that no longer lay eggs, scald them to death with boiling water, then wash them with clean water, and after drying them, they can be sold as medicine.
