CATDOLL : CATDOLL: Silkworm breeding methods and precautions (Silkworm breeding methods and precautions)

1. How to raise silkworms?

Silkworm breeding method:

1. Hatching method: When raising silkworms, you should choose silkworm eggs with smooth particles and black and bright color, wrap the silkworm eggs with toilet paper, and place them in a warm environment. The ambient temperature should be adjusted to around 25°C to promote the rapid hatching of the silkworms. After waiting for more than a day, you can transfer the hatched silkworms to the box.

2. Feeding management: Mulberry leaves are the main feed for silkworms. When raising silkworms, they must be fed once every morning. It is necessary to purchase mulberry leaves from the forest. Try not to randomly pick mulberry leaves on the roadside for feeding, because roadside mulberry leaves are often sprayed with fertilizers. In addition, toilet paper must be used to wipe the moisture in the mulberry leaves to prevent diarrhea in the silkworms.

3. Suitable temperature: Silkworms are suitable for living in a warm environment. When raising silkworms, if the ambient temperature is lower than 10℃, the silkworms will suffer from cold damage and die in large numbers. It is best to adjust the temperature in the silkworm room to between 20-30℃, and open the windows when the temperature is warm to provide air circulation for the silkworms.

4. Clean the room: Silkworms eat and secrete a lot. When raising silkworms, the silkworm room must be cleaned every night to remove the leftover mulberry leaves and excrement to prevent the growth of a large number of pathogens in the air. In addition, the silkworm room must be sprayed with quicklime water once a month to clean it and reduce the probability of silkworms getting sick.

5. Control the density: If the silkworm seats are uneven, the silkworms will develop unevenly. Therefore, before each feeding, the seats should be expanded and evenly distributed, and it is best to ensure that the small silkworms do not touch each other and the big silkworms do not overlap.

6. Use leaves properly: In order to promote the uniform development of young silkworms, it is necessary to feed silkworms with leaves according to the leaf standards for silkworms before different ages, and avoid using mulberry leaves of different ages. In addition, the thickness of mulberry leaves should be uniform.

7. Replace the position of silkworm foil in time: The silkworms in different areas of the same silkworm room are affected differently by temperature. For example, the area on the silkworm rack close to the open flame has a higher temperature, and the silkworms grow faster. On the contrary, the temperature is slightly lower, and the silkworms grow slowly. Therefore, it is necessary to pay attention to replacing the position of the silkworm foil frequently. It should be replaced once a day during the young silkworm period.

8. Feeding at the right time: If you feed too early, some silkworms will not have an appetite, and some will even sleep, which will cause the same batch to eat mulberry leaves at different times and develop unevenly. Therefore, you need to feed them at the right time. Before they go to sleep, if the silkworms develop unevenly, you should delay feeding them by 3-4 hours after sleep compared to normal feeding. This will ensure that the silkworms that develop slowly and the silkworms that develop quickly can eat leaves at the same time.

9. Add nets to promote green silkworms: Generally, after two feedings after dormancy removal, if the dormancy is still uneven, it is necessary to add nets to promote green silkworms. The green-headed silkworms that have been raised should be placed near the heat source, and the green-headed silkworms of large silkworms can be placed on the top layer of the silkworm rack. A very small number of poorly developed and weak silkworms should be replaced decisively.

10. Use grid clustering at the right time: Grid clustering is one of the key measures to improve the quality of sericulture. Pick up bright silkworms and put them into clusters appropriately, and do not pick up immature silkworms or over-mature silkworms and put them into clusters.

2. How to raise silkworms?

How to raise silkworms

1. Pay attention to hygiene during the breeding period. Do not let water droplets on the feed to prevent mold on the feed. Do not let the silkworms come into contact with various household insecticides, mosquito repellents, perfumes, camphor, cigarettes and other strong odors to avoid causing harm to the silkworms.

2. To increase the fun, you can use the color silkworm and color cocoon technology to turn the original white silkworms into colored silkworms. If these silkworms are fed with ordinary feed, they will produce white cocoons. If you choose special color cocoon feed, they can produce light red, yellow, light blue and other colored cocoons. The special color cocoon feed should be fed to the silkworms on the 2nd and 3rd day of the 5th year, and it should be fed for 3 to 4 days in a row. It should be noted that different color feeds should be raised separately.

3. What is the correct way to feed silkworms?

1.

Feeding method:

Silkworms of age 4-5 are in the adult stage, and the suitable growth temperature is 25 degrees. Silkworms have weak resistance to high temperature, humidity and carbon dioxide, eat a lot of mulberry leaves and produce a lot of excrement. They can be raised indoors on the ground or outdoors on sheds.

2.

After receiving the silkworm eggs, protect them in a suitable environment to allow the embryos to develop normally. The specific steps are:

In a disinfected silkworm room, lay the silkworm eggs flat on the silkworm plaque with the eggs facing upward. The room temperature should be 24℃ and the difference between dryness and wetness should be 2-2.5℃ on the 1st to 4th day. The room temperature should be 27℃ and the difference between dryness and wetness should be 1.5-2℃ on the 5th to 10th day. When the embryos develop to the later stage and a small number of silkworm eggs are found to be blue dots, immediately cover the silkworm eggs with black cloth. After about 40 hours, that is, 4-5 o'clock before dawn on the third day, remove the black cloth, wrap the silkworm eggs with white paper, with the eggs facing upward, turn on the light to let the ants bite through the egg shells and hatch.

The main technical measures for raising silkworms are:

(1) Improve the environment and ensure ventilation to prevent stuffiness.

(2) Build a shed to provide shade and prevent hot air from entering the silkworm room.

4. How to raise silkworms well and how to manage large-scale breeding?

I grew up in a silkworm-raising family and have been in contact with silkworms since childhood. When raising spring silkworms, you should pay attention to keeping them warm. Keep them in a room with an average temperature of more than 20 degrees. Sprinkle lime on the silkworms evenly before feeding them mulberry leaves every morning and evening to keep them dry and ventilate the silkworm room. Mulberry leaves for feeding silkworms should also be disinfected every day. After disinfection, wait until the mulberry leaves are dry before feeding them. As the silkworms grow up day by day, you should frequently change the silkworm tools and disinfect them. Don't let the silkworms be too dense, as they are prone to illness. Spring silkworms will make cocoons in seven or eight days. Summer silkworms will make cocoons in five or six days when the weather is warm. Now you can raise six or seven seasons of silkworms a year.
