CATDOLL : CATDOLL: Where do earthworms usually live?

Earthworms are annelids of the order Oligochaeta, class Chaetopoda. They generally live in dark and moist soil 10-30 cm deep in moist, loose soil rich in organic matter. They live in fertile gardens, vegetable gardens, cultivated land, ditches, rivers, ponds, channels, sewers near canteens, garbage dumps, and under water tanks. The moisture of the body surface is also closely related to the respiration of earthworms, because they do not have special respiratory organs and mainly exchange oxygen and carbon dioxide through moist epidermis. Earthworms need good ventilation when they live in order to replenish oxygen and discharge carbon dioxide. They are particularly sensitive to ammonia and smoke. When ammonia exceeds 17 parts per million, it will cause the earthworms to secrete more mucus and die in groups. Although a humid place is the best living environment for earthworms, when it rains, it is obvious that due to the infiltration of surface water, the degree of compaction of the soil surface is higher than that on sunny days, and the air permeability of the soil suddenly decreases, so they need to crawl out to breathe.

Look at this first:

Living habits of earthworms:

Because there are many varieties of earthworms, their living environments and preferred feeds are also different, so their living habits are slightly different, but they all have in common that they like warmth, humidity, darkness, air permeability, and are afraid of light, salt, shock, and spicy food. They are introduced one by one here for reference by breeders.

1. Likes warmth but afraid of heat or cold

Earthworms like to live in a warm environment. They are afraid of both cold and heat. They hibernate at 0℃-5℃, stop growing above 32℃, and die above 40℃. The suitable temperature is 15℃-30℃, and the best temperature is 20℃-25℃. If we want to obtain good breeding benefits, we must maintain the best temperature of 20℃-25℃ for the breeding environment all year round.

2. Likes moisture and is afraid of soaking

Earthworms like to live in a humid environment, not too dry, but not too wet, and cannot be soaked (except for water earthworms). The humidification mentioned here includes two aspects, one is the humidity of the breeding base soil, and the other is the air humidity. Generally, the humidity of the breeding base soil is required to be 40%-60% (it is better to hold the base soil with fingers and see water but not flow down), and the relative humidity of the air is preferably adjusted to 60%-80%.

3. Like darkness and fear light

Earthworms like to live in the dark. They usually burrow under the soil or in the substrate to find food. They also crawl out of the ground at night to find food. They are afraid of light, so they develop the habit of hiding during the day and coming out at night. Although earthworms have no eyes and cannot see light, their bodies are covered with photosensitive organs. Strong light is extremely detrimental to the growth and reproduction of earthworms, so earthworms always move in the dark. The breeding environment should be selected in a dark place.

4. Prefer sweet and dislike spicy food

Earthworms like to eat sour, sweet, and fishy food, such as rotten tomatoes, watermelon rinds, rotten fruits, fish washing water, etc. They are most afraid of spicy food, such as green onions, garlic, peppers, etc. When feeding earthworms with urban household garbage, spicy food should be picked out before feeding.

5. Prefer quietness and fear of shock

Earthworms like to live in a quiet environment and are most afraid of vibration. The breeding farm should be selected in a quiet place. Do not vibrate or frequently turn the base soil up and down. Frequent vibration will have a negative impact on the growth and reproduction of earthworms.

6. Like acid and fear salt

Earthworms like to live in acidic or neutral soils, or in environments with water sources. They are most afraid of being close to salt or alkaline soils, or saline-alkaline water sources. If you encounter saline-alkaline soils or water sources, you need to adjust the pH. If it is too alkaline, use ammonium dihydrogen phosphate to adjust it, or you can use 2% coal water to adjust it, otherwise the earthworms cannot survive.

Earthworms live in moist soil with a lot of decayed matter. When digging earthworms, it is best to use chopsticks or something like that because iron tools like shovels can easily damage their bodies.

Please give me some points

In the wet soil, if you go to the farmer's vegetable field on a rainy day, you may get a harvest.
