CATDOLL : CATDOLL: Humidity and temperature for earthworm breeding (the relationship between humidity and temperature for earthworm breeding)

1. Can earthworms reproduce quickly if you raise them yourself?

Fast! For earthworms to reproduce quickly, the temperature needs to be kept at around 20-27℃, their bodies need to be kept moist, the humidity of the feed needs to be kept at around 70%, and the pH value of the soil needs to be in the range of 6-8. The more aerated the soil, the better. When feeding, you should also pay attention to the amount of food, high quality, to prevent the decline of reproductive capacity and the spread of diseases and pests.

2. What are the requirements of earthworms for their living environment?

1. The activity temperature of earthworms is 5-30℃, they enter a dormant state at 0-5℃, and die below 0℃. The optimum temperature is 20-27℃.

2. The humidity of the feed should be maintained at 70%. Earthworms use their skin to breathe, so their bodies must remain moist. Water in earthworms accounts for more than 75% of their body weight. Preventing water loss is the key to their survival.

3. They feed on decaying plants or other organic matter. They eat soil and sand to obtain organic matter. Earthworms grow in a pH range of 6-8 and produce the most cocoons.

3. Why do earthworms always die when I raise them at home?

There are usually only two reasons that can cause large-scale deaths: feed poisoning and lack of oxygen.

Feed poisoning: Feed poisoning is generally caused by pollution or protein poisoning. Everyone must check the feed they feed. When earthworms show spasms, thickening, redness and swelling, this is a precursor to feed poisoning.

Lack of oxygen: There are many reasons for earthworms to suffer from lack of oxygen, such as the volatilization of large amounts of toxic gases caused by feed fermentation or excessive soil moisture, which can lead to obstructed breathing in earthworms and eventually cause death from lack of oxygen.

The adaptable temperature of earthworms can be between 5 and 30 degrees Celsius, and the humidity should generally be maintained at around 50%. If the humidity is too low or too high, it may cause the earthworms to escape.

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.

5. How to breed large earthworms?

1. Container: When raising earthworms, you need to use a water tank or basin, and then clean and disinfect it.

2. Substrate: Use silt, animal manure and leaf mold to prepare the soil substrate.

3. Planting seedlings: Place the earthworm seedlings in a container filled with substrate.

4. Maintenance: Cover the soil with straw to block out light, and water it once a week to allow the earthworms to reproduce quickly.

6. Does earthworm farming have any climate requirements?

1. Temperature

Generally speaking, the activity temperature of earthworms is 5-30℃, they enter a dormant state at 0-5℃ and die below 0℃. The optimum temperature is around 20-27℃, which is also the optimum temperature for earthworm cocoon eggs. They stop growing at above 32℃ and die at above 40℃.

2. Humidity

Earthworms use their skin to breathe, so their bodies must remain moist. Water accounts for more than 75% of their body weight. Preventing water loss is the key to their survival. Therefore, the humidity of the feed should be kept at around 70%.

7. What is the suitable temperature for raising earthworms?

The best temperature for raising earthworms is 15℃-25℃. Generally speaking, earthworms are active at 5-30℃, enter a dormant state at 0-5℃, and die below 0℃. The optimum temperature is around 20-27℃, which is also the optimum temperature for earthworm cocoon eggs. They stop growing above 32℃ and die above 40℃.

Therefore, in summer and autumn, earthworms should be raised with shade sheds to cool down (the mulberry garden has natural shade conditions, but the mulberry trees still need to be temporarily covered with shade after being cut in summer and before they germinate and grow tightly), and in winter, the shed should be heated up (the existing equipment in the silkworm room can be used) or the mulberry garden should be covered with wheat straw to keep warm and increase the temperature, so as to facilitate the normal growth and reproduction of earthworms. Extended information: earthworms use their skin to breathe, so the body of earthworms must be kept moist. The water content of earthworms accounts for more than 75% of their body weight. Preventing water loss is the key to the survival of earthworms, so the humidity of the feed should be kept at about 70%.

Earthworms grow best in a pH range of 6-8 and produce the most cocoons.

Earthworms breathe by relying on oxygen diffused into the soil from the atmosphere. The better the soil is ventilated, the more vigorous their metabolism is. Not only do they produce more cocoons, but their maturity period is also shortened.

Insufficient or low-quality food will cause maggots to compete for food, leading to decreased fertility, the spread of pests and diseases, increased mortality, and the escape or slow growth of some earthworms.
