CATDOLL : CATDOLL: How to control the humidity of earthworms (How to control the humidity of earthworms)

1. What are the five technical points of earthworm farming?

Earthworms can appear in March.

The five technical points of earthworm farming are as follows:

1. Preparation of earthworm bed

There are two ways to make earthworm beds, one is open-air and the other is indoors. Each earthworm strip is at least 3m short and 7m long, with a width of 0.5m-1.0m. There are two ways to make earthworm beds in the open air, one is to cover the earthworm bed with straw, and the other is to set up a sunshade net above the earthworm bed; there are also two ways to make earthworm beds indoors, one is in various houses, and the other is a simple shed covered with asbestos tiles.

2. Stocking measures

During the period of large-scale earthworm farming, stocking work needs to be done well. The base material can be placed in the breeding site, and the stacking height can be controlled at about 20 cm to facilitate the construction of the culture medium, and a sidewalk should be left to ensure that daily management work can be carried out.

3. Bait management

Earthworms have a wide range of food habits. Almost all plant residues, humus, rotten animals and domestic garbage are food for earthworms. Before feeding, they must be processed. First remove impurities, then chop straw, weeds, sugarcane bagasse, etc., add pig, cow and chicken manure, pile them into a 1m high cone, cover them with straw mats or plastic film for fermentation. For the sake of success, first try feeding with a small amount of earthworms. If there is no adverse reaction, you can feed all of them.

4. Environmental Control

Temperature: The optimum temperature is 10℃-30℃. In winter, just cover it slightly to prevent the earthworms from hibernating, but avoid exposure to the sun and rain.

Humidity: earthworms do not require high humidity, the relative humidity is 60%-70%. Generally, fresh cow dung can be directly thrown in. If it has been piled for too long and is too dry, you can spray some water on it.

5. Earthworm hatching

In the season with a temperature of 15-28℃, the egg cocoons are cleaned out from the earthworm breeding bed every 10-15 days and placed on the pre-prepared earthworm bed for hatching. Earthworms are hermaphrodites and cross-fertilization occurs. Sexually mature earthworms lay eggs every seven or eight days, and one egg can hatch three or four small earthworms. They mature in two to three months and can reproduce ten times in four to six months.

2. 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%.

3. 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.

4. How can I raise earthworms indoors in pots or wooden boxes?

Hello, to breed earthworms, you must first understand their habits. First, the humidity should be maintained at 60%-80%. Too high humidity can easily cause the earthworms to die due to poor tolerance. Second, the survival temperature is 0-32 degrees, and the best breeding temperature is around 20 degrees. Third, the breeding environment should have good ventilation. Fourth, the stability of the food. Due to the diversity of family breeding food, the pH value of the food is very important for the survival of earthworms. Earthworms can only live in a pH-neutral environment. After the above points are done, find a wooden box. The density of earthworms should not be too large. Add about 20 cm thick humus soil. Earthworms are very hardy and you can breed them with peace of mind.

5. What is the suitable water content for earthworm growth?

1. Humidity The water content of earthworms is 70% to 80%. They usually maintain their balance by secreting body fluids. Therefore, they must live in a humid environment. The humidity adaptation range is 30% to 80%. For example, the suitable humidity for Pheretima Williamii (green earthworm) is 30% to 45%, while the suitable humidity for Eisenia fetida (red earthworm) is 50% to 80%. This habit of earthworms makes them live in burrows and nests. High or low humidity environments are not conducive to their normal survival. If the humidity is lower than the limit, the earthworms will be dehydrated and extremely atrophied, semi-dormant or die. On the contrary, they will die as the temperature rises.

2. Temperature Earthworms are cold-blooded animals and are very sensitive to changes in temperature. When the temperature drops to 10°C, earthworms stop eating; when it drops to 4°C, they enter a hibernation state; below 0°C, they will freeze or die. Generally, large and medium-sized earthworms hibernate deep underground; while small earthworms mostly gather in groups and form balls in warm soil to hibernate. When the temperature rises to 8-10°C the following year, they crawl to the surface to move around. Weak and shrunken earthworms have a very low survival rate and it is difficult for them to survive the spring. When the temperature exceeds 30°C, their growth is also inhibited, they quickly shrink, their body color becomes darker, and they burrow into the deep soil and do not move. When the temperature is above 35°C, they completely stop eating and enter a dormant state, their bodies completely shrink, and they feel extremely dull. Once the temperature drops, they can return to their original state. The best temperature is 20-25°C.

3. Diet Earthworms are omnivorous animals that can eat both meat and vegetables. The plant feed sources for earthworms are extremely rich. In artificial breeding, waste is almost always used to feed them in rural areas. The feed sources for earthworms include a variety of livestock and poultry manure, manure, grass, water plants, straw, etc., as well as leaves, waste vegetable leaves, rotten claw fruit, dregs, biogas residues, waste paper pulp, etc. There are also animal feeds, which have a more significant effect on the weight gain and reproduction of earthworms. For example, the leftovers and sewage after slaughter, the leftovers of meat and vegetables from canteens and restaurants are the feed sources that earthworms like.

4. Illuminance Earthworms are photophobic animals that hide during the day and move at night. They like to live in dark and humid soil environments. They are extremely afraid of direct ultraviolet rays, so they don't show up easily in sunlight or strong electric lights. They will only leave their nests and expose themselves when they encounter enemies, pesticide damage, flooding, high temperature, dryness, hypoxia, etc. But earthworms are not afraid of red light. The role of earthworms in nature: They can loosen the soil, increase soil organic matter and improve the structure. They can also promote acidic or alkaline soil to become neutral soil, increase fast-acting components such as phosphorus, and make the soil suitable for the growth of crops. Because earthworms are rich in protein, they can be used as feed for livestock, poultry and aquaculture to increase production. Earthworms also occupy a certain position in pharmacology. They are common Chinese medicinal materials with antipyretic, antispasmodic, activating, antiasthmatic, antihypertensive and diuretic effects. Earthworms can secrete a special enzyme that can decompose protein, fat and wood fiber. Therefore, leaves, straw, livestock and poultry feces, domestic garbage, activated sludge and waste from papermaking and food industries can all be its food. Earthworms can eliminate environmental pollution to a certain extent. Therefore, in recent years, many countries have established earthworm breeding factories and called earthworm breeding factories "environmental purification devices." Because earthworms can absorb trace metals such as mercury, lead and cadmium in the soil, the amount of these metal elements accumulated in the earthworms is 10 times the amount outside. Therefore, some scientists believe that earthworms can be used as monitoring animals for heavy metal pollution in the soil.
