1. What are the methods of earthworm farming?

How to grow earthworms indoors

① Box culture method: As the name suggests, box culture method is to use boxes to culture earthworms, such as large wooden boxes, foam boxes, various basins, large barrels, large jars, etc. It is recommended to choose varieties such as Chizi Ai earthworms, Beixing No. 2, and red earthworms. These earthworms like to live in rotten grass piles, compost, various feces, dead branches and rotten leaves, rotten vegetable leaves, rotten fruits, and some waste and domestic garbage.

Knowing their habits will make it easier to breed them. It is especially important to note that these organic matter, garbage, and animal feces cannot be used directly to breed earthworms. Instead, they must be piled up and fermented first, and then the temperature drops before they can become the substrate for breeding earthworms. In addition, the breeding humidity should be maintained at 60-70%, and the temperature should be between 15-25 degrees.

② Pit breeding method: Pit breeding method is to use earth pits, brick pits, dilapidated animal pens, under the eaves, corners of the wall, etc., or you can use stones to build a breeding pond. The best depth of the earth pit for breeding earthworms in this way is about 50 cm. The size of the area does not matter. Add fermented nutrient soil to the pit and you can introduce earthworms. In the later stage, you can add a thin layer of feed on the soil, and the soil moisture should be controlled well.

How to farm earthworms outdoors?

① Orchard farming method: Choose an orchard with flat terrain and irrigation, dig a 40 cm wide and 20-25 cm deep ditch between the rows of trees, then add various animal manure, weeds, straw, dead branches and leaves and other rotten organic fertilizers, and cover them with a layer of soil. The amount of organic fertilizer required is about 5,000 to 10,000 kilograms per mu. In addition, the drainage ditch should be opened at a certain distance, and the water content should be maintained at about 30%. The feed field farming method is basically similar to this. Add organic fertilizer to the ground and cover it with soil to start farming. It is not difficult.

② Garden farming method: The garden has sufficient water and fertilizer. If it is carefully managed, it is very conducive to the growth of earthworms and the yield will be very high. The garden farming method uses 5,000 kilograms of organic fertilizer per mu. Earthworms can only be released after the vegetable seedlings emerge from the soil or after they are planted and survive. Garden farming should reduce the use of chemical nitrogen fertilizers and pesticides or not use them. The harvest period of earthworms can be determined according to the picking period of vegetables.

2. 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.

3. What are the basic methods of earthworm farming?

Technical methods for raising earthworms: pot culture method, box and basket culture method, pond culture method, ditch culture method, fertilizer pile culture method, gardening, field culture method, ground greenhouse circulation culture method, semi-underground greenhouse culture method, plastic greenhouse culture method, and open-air culture method.

Pot culture method: This method is suitable for small-scale breeding in the homes of members, urban residents or for related scientific research. Potted flower pots, pots and other discarded ceramics can be used for breeding. This type of breeding method is simple, easy to manage, easy to move, and easy to control temperature and humidity.

4. How to breed earthworms?

1. Artificial earthworm breeding equipment is simple and easy to manage. Generally, medicinal earthworms can be cultivated in the open space in front of and behind the house, in the courtyard, as well as old wooden boxes, waste barrels, pots, bamboo baskets, brick pools, seedling hotbeds, etc. It can also be combined with vegetable fields, orchards, nurseries, etc. to cultivate earthworms, which can benefit from dual utilization.

2. Choose different varieties of earthworms according to different regions, needs and conditions. Generally, choose those that are easy to raise and reproduce and suitable for local soil and climate conditions. For example, in areas with many vegetable gardens, orchards and nurseries, green earthworms can be cultivated and combined with field planting. This can improve soil fertility, promote plant production and harvest earthworm animal protein feed.

3. The breeding method of earthworms can be determined according to the habits and uses of earthworms. There are three main types of breeding: indoor breeding, field breeding and factory-scale breeding. Put the base material into wooden boxes, bamboo baskets, porcelain basins or brick pools, and then put the earthworms in for breeding. During the breeding period, spray water frequently to maintain a humidity of 60% to 70% (generally, it is better to squeeze them into balls by hand and let them spread out), and cover them with straw mats, straw curtains and old sacks to block light. They can grow normally at temperatures between 13 and 28 degrees Celsius.

4. Use the air-raid shelter breeding method: Urban air-raid shelters are basements, which are warm in winter and cool in summer, and the surrounding humidity is high, which is suitable for breeding red earthworms. The breeding method is the same as box breeding and pit breeding. You can light a lamp at night to prevent escape and provide a certain light source that is conducive to the growth of earthworms.

How 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.
