CATDOLL : CATDOLL: What are the seasons and methods for raising silkworms? (Pictures of What are the seasons and methods for raising silkworms?)

1. Which season is suitable for raising silkworms?

Spring or Summer

Answer 1. Silkworm rearing time: Generally, silkworm rearing takes place in spring and summer (starting around April). Silkworms mainly feed on mulberry leaves, so silkworm rearing needs to be basically consistent with the growth cycle of mulberry trees, so that there are enough mulberry leaves for silkworms to eat. 2. Silkworm rearing frequency: In Jiangsu and Zhejiang silkworm regions, silkworm rearing can be carried out theoretically from April to November each year, but generally only 3-5 times.

2. What is the season for raising silkworms?

1. Silkworms are usually raised in spring and summer, which is roughly the same as the growth cycle of mulberry trees, to ensure sufficient supply of mulberry leaves. Prepare food: Mulberry leaves must be washed with clean water and dried before feeding. Do not feed silkworms with yellow and rotten leaves, otherwise the silkworms will be poisoned or have diarrhea. In order to prevent the excess leaves from wilting quickly, put them in a plastic bag, tie the bag tightly, and place it in a cool place.

2. Feed the silkworms with leaves 4 times a day, early in the morning, at noon, in the afternoon, and at night. The amount should be appropriate each time to avoid waste. You can put more leaves at night because the silkworms eat mulberry leaves all night. Ant silkworms should be fed with young leaves, and the leaves are best cut into pieces or strips.

3. Clean up the feces and leftover leaves frequently: When changing leaves for the silkworms, you can directly cover the old leaves with new leaves, and remove the old leaves after the silkworms have crawled onto the new leaves. This can reduce the casualties of the silkworms and facilitate the removal of leftover leaves and silkworm feces.

4. Do not spray pesticides in the silkworm room as this will harm the silkworms.

3. New technologies and methods for silkworm breeding?

1. Preparation

Before raising silkworms, be sure to prepare a clean, odor-free cardboard box, and then poke some small holes on the top of the box to facilitate ventilation.

2. Incubation

Place the silkworm eggs in a carton at a temperature of 21-29°C. The incubation time is generally about 11 days.

3. Feeding

(1) When the silkworms are about to hatch, put an appropriate amount of fresh mulberry leaves into the cardboard box for the silkworms to eat.

(2) When silkworms are in the young stage, they can be fed with fresh and tender mulberry leaves. When they are in the adult stage, they can be fed with ordinary mulberry leaves.

(3) Before feeding, be sure to check the mulberry leaves carefully to pick out diseased, moldy, and insect-infested leaves, and make sure there is no water on the leaves, otherwise the silkworms will easily suffer from diarrhea after eating them.

4. Cleaning

(1) The old mulberry leaves in the cartons must be removed regularly and replaced with fresh mulberry leaves. All silkworm feces in the cartons must be cleaned up.

(2) When changing mulberry leaves to clean the feces, you must use a brush. The silkworms on the old mulberry leaves can be gently swept onto the new mulberry leaves, and then the silkworm feces and old mulberry leaves in the cardboard box are cleaned, and finally the new mulberry leaves are put into the cardboard box.

(3) If there are dead silkworms in the carton, be sure to clean it up immediately to prevent other silkworms from being infected.

4. What are the correct methods and techniques for raising silkworms?

1. Mulberry leaves should be picked, transported and stored properly. Try to pick leaves in the morning or evening, transport them as soon as they are picked, and pack them loosely for fast transportation. After the picked mulberry leaves are loosened, put them in the mulberry storage pool or mulberry storage room, and store them properly to prevent them from being blown away by the wind or piled up and heated and deteriorated, which will cause waste of mulberry leaves.

2. Prevent mulberry leaves from wilting. During the young silkworm stage, use a kang bed (room) and cover the mulberry leaves with plastic film to keep the temperature and moisture, so that the mulberry leaves remain fresh. During the adult silkworm stage, close the doors and windows appropriately after feeding the silkworms, and open the doors and windows for ventilation after the silkworms have eaten about 70% of the mulberry leaves, which can effectively prevent the mulberry leaves from wilting.

3. Ensure the temperature of the silkworm room. The suitable temperature for large and small silkworms is 24℃ and 25℃ respectively. Within the suitable temperature range, the silkworms have a strong appetite, which reduces the defective mulberry leaves and improves the leaf-silk conversion rate.

4. Promote less-return rearing and mulberry-strip rearing. Labor-saving silkworm rearing technologies such as flat three-dimensional rearing of small silkworms once a day, rearing of full-age silkworms twice, and rearing of large silkworms in mulberry strips not only improve the efficiency of silkworm rearing, but also help silkworms eat mulberry leaves, saving about 5% of mulberry leaves compared with ordinary rearing.

Summer and autumn silkworm breeding should pay attention to

1. Prevent pesticide poisoning. During the silkworm-raising season, do not spray organic pesticides such as dimethoate in the silkworm room and the fields near the mulberry fields, as the smell will cause poisoning to the silkworms; mulberry leaves should be fed to the silkworms only after they have been tested and confirmed to be non-toxic.

2. Mosquito-repellent incense or mosquito repellent or insecticide is prohibited in the silkworm room. If it is used in the house near the silkworm room, the doors and windows of the silkworm room should be closed to prevent the silkworms from being poisoned.

3. Screen doors and windows should be installed in the silkworm room to prevent flies from entering the room and harming the silkworms, and "silkworm fly killing" emulsion should be added or sprayed on the silkworm bodies to kill the maggots.

5. What is the season for raising silkworms?

Sericulture is generally carried out in spring and summer. Sericulture is an important skill of the working people in ancient my country. The method of planting mulberry trees and raising silkworms was invented by Leizu, the wife of Huangdi. Sericulture can eventually produce an important silk product, namely: silk. Silk occupies an important position in human economic life and cultural history. The main commodity of the famous historical event of the Silk Road was silk.

6. What are the silkworm breeding techniques and precautions?

1. First of all, the best time to raise silkworms is from April to May every year. In this season, you can buy silkworm eggs, which are silkworm eggs, outside. You can directly place the silkworm eggs on mulberry leaves.

2. Under normal room temperature in April and May, that is, between 20 and 25 degrees Celsius, silkworm ants will hatch into silkworm babies within two days.

3. When it hatches into a silkworm, it starts to eat by itself. The food that the silkworm eats is clean and fresh mulberry leaves, which means that the mulberry leaves collected must be washed and then fed to it.

4. However, it should be noted that silkworms cannot eat raw water, so the mulberry leaves should be washed and dried before feeding them.

5. The silkworms continue to grow while eating mulberry leaves. After the fourth molting, they begin to spin silk and make cocoons. Then they will break out of the cocoon!

7. What are the time and customs for raising silkworms?

Silkworm breeding season

Spring and summer should be roughly the same as the growth cycle of mulberry trees to ensure an adequate supply of mulberry leaves.
