How to breed earthworms

The vitality of the earthworm is very strong. As long as it is not exposed to the outdoors, there is no wind and rain, and there is no direct sunlight, the earthworm can survive. Now, let's learn about the key points of earthworm breeding with me. I hope it will be helpful to you!

How to breed earthworms: pot breeding

You can choose a plastic basin with a smooth inner wall, with a height of more than 15 cm and a diameter of more than 45 cm, and you can directly culture it with built-in breeding soil. The eggs can also be hatched in basins, and the hatched larvae can be raised in basins according to size. Basin breeding is suitable for small-scale breeding, with low investment, easy operation, and flexible movement. The disadvantage is that the temperature and humidity are difficult to control, and the output efficiency is low.

How to breed earthworms: tank breeding

Cylinder culture is generally suitable for unheated or slightly heated culture. Choose a tile pot or a cylinder pot with a smooth inner wall, the height should not exceed 1 meter, half or part of it should be buried underground, and the breeding soil can be placed 40-50 cm thick. In spring and autumn, when the temperature is 0-20 degrees, it can be slightly heated to shorten the hibernation period of the earthworm. The advantage is that the underground temperature and humidity are balanced and stable, the earthworm grows well, has a long lifespan, and has good output quality. The disadvantage is that the cycle is long, the yield per unit area is low, and it is easy to be damaged by rodents.

How to breed earthworms: Pond breeding

Plane pool culture is the predecessor of three-dimensional greenhouse pool culture. Use bricks to build a square pool of 40-45 cm in height 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, use cement slurry to stick 6-8 cm wide glass strips (if there is no glass strip, thick film can be used instead) to prevent soil beetles from running away. It can be heated for breeding, and the doors, windows and surrounding walls must have good sealing performance to prevent rodent and ant damage. The advantages are: good growth of insects, easy management, and low investment. The disadvantages are long cycle and low utilization rate per unit area.

The breeding method of earthworm: raising in a matrix pond

We advocate the most advanced greenhouse three-dimensional breeding model. Its advantages are one-time investment, many years of benefits, fast output and high efficiency. However, the investment is large. It takes about 5,000 yuan to build a 100-square-meter three-dimensional breeding pool. Farmers should determine the breeding form according to their own conditions. In the process of artificial breeding of earthworms, heating breeding can shorten the growth cycle of earthworms by two-thirds. Although heating increases some breeding costs, it is insignificant compared to the benefits generated. Three-dimensional pool breeding requires more heating. Since the three-dimensional breeding earthworms do not go deep into the soil, they cannot withstand the cold surrounding them in the cold winter and die.

1) The specific requirements and practices of three-dimensional pond culture are:

1. House. The house for the monoculture pond should not leak, the walls around it should be intact, and it can be flat or pointed. If the terrain is low, dig a ditch around the house for drainage. The house is generally more than 2.6 meters high, about 3.6 meters wide, and 8-12 meters long. If the original doors and windows are not in the center of the aisle, try to change them to the center, with a width of no more than 1 meter, a window height of no more than 1.5 meters, and a door height of no more than 2 meters.

2. Walls. Mud bricks, red bricks, and cement bricks are all acceptable, but cement mortar should be used on one side. Leave doors and windows at both ends of the house and build two interlayer walls with vertical bricks, with a gap of 5-10 cm between the walls. When building interlayer walls, top bricks should be built at intervals to support the original old wall to prevent the partition wall from collapsing. Some people only build one interlayer wall, and put perlite in the empty layer. In this state, the earthworm house is warm in winter and cool in summer, and the perennial state is like a basement, which can ensure the normal growth of earthworms all year round.

3. Pool body. After the partition wall is built, leave a 1-meter walkway according to the remaining area in the house. Design the size of the breeding pool board (the size of the pool board should not be too large, generally about 1 square meter), the thickness of the breeding pool board is 3-3.5 cm, and after the size is determined, it is cast with reinforced concrete, and 4 mm steel bars are selected. After the pool board is cast and maintained, the three-dimensional pool can be built. There are 3 bricks per layer (about 40 cm high). After building one layer, the inner wall is painted, and then another layer of pool board is laid. 6-7 layers can be built, and the top is capped. Grass or other insulation materials are laid in the gap between the pit top and the roof. Leave a 19-20 cm operation window on one side of the pit house walkway. Stick a hard plastic paper about 4 cm extending into the pit pool on the operating window to prevent the ground beetle from turning over and running away (note that glass strips cannot be used here, as the glass strips will scratch your arms during operation). After the pit house is built, the surrounding indoors should be painted and the gaps should be filled to prevent rats and ants from entering. 4. Heating facilities. Build 1-2 fire dragons with bricks in the breeding room. It is more appropriate to use honeycomb coal or raw coal for heating. The fire dragon is set on a flat surface, and the heat source rises slowly from the bottom to the top. Even if the furnace is extinguished for several hours, there is still residual heat on the fire dragon. The combustion furnace can be set outdoors or indoors. A cover should be set on the indoor furnace to prevent gas leakage. The exhaust gas after combustion is discharged outdoors. There are many ways to heat, which should be adapted to local conditions.

2) Commonly used heating methods

1. Electric heating method: It is convenient and easy to operate to use an electric stove or heater for heating. It is best to use a humidifying heater. You can put a pot on the electric stove to boil water to increase the humidity of the air. Electricity is pollution-free, but the cost is high. You should pay attention to electricity safety. It is generally used when the temperature of incubating eggs is not enough in winter.

What do earthworms eat and how to breed them

answer

The earthworm mainly feeds on bran, rice bran, soybean meal, fish, meat, peanut cakes and other foods. It is an omnivorous insect. The earthworm, also known as the earthworm, has the characteristics of strong reproduction and wide adaptability. It likes to live in dark and humid loose soil rich in humus. It hides during the day and moves at night. The optimal temperature for its growth is 28-30°C. It can usually be found in the loose soil at the foot of the stove or the kiln.

1. What do earthworms eat?

1. The earthworm mainly feeds on bran, rice bran, peanut cakes, soybean meal, miscellaneous fish, meat and various green vegetable leaves. It is an omnivorous insect with the characteristics of strong reproductive capacity and wide adaptability.

2. The earthworm likes to live in dark, moist and loose soil rich in humus. Its traces can often be found in the moist and warm loose soil of sweet potato cellars, underground kilns and stove feet.

3. Because the earthworm is afraid of sunlight, it hides during the day and moves at night. The suitable temperature for its growth is 28-30°C. The temperature should not be lower than 0°C or higher than 38°C, as it will cause the death of a large number of adults and nymphs.

2. How to breed ground beetles

1. Site construction

(1) Generally, you can use boxes or pots to breed earthworms, and you need to prepare breeding soil for them.

(2) The method of making breeding soil is to add an appropriate amount of chicken manure and pig manure to the garden soil that is rich in humus, loose and fertile, and then expose it to the sun.

2. Larvae management

(1) When hatching earthworms, keep the humidity of the breeding soil at around 40% and the temperature at 25-30°C. When the larvae hatch, they need to be raised separately from the mother insects.

(2) The larvae are usually fed with concentrated feed. When feeding, you can first spread the feed evenly on the breeding soil, and then turn the feed into the soil layer, generally to a depth of 2-3 cm.

3. Feeding and management

(1) In the hot summer, it is necessary to provide sufficient drinking water for the Chinese ground beetles. You can spray an appropriate amount of water in the breeding area to maintain the humidity of the breeding soil and lower the temperature of the breeding soil.

(2) Keep the environment dry in winter, feed semi-dry and wet feed, and use straw to keep warm when the temperature is low.

4. Pest and disease control

(1) Diseases: The main diseases of Chinese ground beetles include pot-bellied disease and fungal infection. The method for preventing and controlling pot-bellied disease is to adjust the dryness and humidity of the feed and the breeding soil. The moisture content should not exceed 10%. The method for preventing and controlling fungal infection is to replace the breeding soil and grind 0.25g of tetracycline into powder before feeding.

(2) Pests: The main pests of ground beetles are ants and other pests. Generally, tung oil can be applied on the wall to control ants. At the same time, it is also necessary to control rats, cats and other pests.
