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. 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.

3.

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.

3. How do beginners raise silkworms?

Breeding for beginners

When a novice raises silkworms, he needs to prepare a clean, odor-free ordinary paper box or wooden box, then put the purchased silkworm eggs into the paper box, and place the box in a greenhouse that can regulate the temperature. The indoor temperature should be controlled between 21-29 degrees to promote rapid hatching of the silkworm eggs.

Feeding mulberry leaves

Silkworms grow very fast and have a high demand for mulberry leaves. When raising silkworms, you need to prepare fresh, pesticide-free green mulberry leaves. Use a sharp knife to cut the mulberry leaves into small pieces, and then spread them on the box. Allow the silkworms to eat freely, and feed them mulberry leaves every 3-4 hours to ensure that there is enough food.

Suitable environment

Silkworms live in a clean environment. When raising silkworms, if the environment is too dirty, the silkworms will be infected with diseases. The boxes need to be cleaned every 2-3 days. The feces and leftover mulberry leaves in the boxes can be cleaned out, and the windows should be opened from morning to afternoon every day to ventilate the silkworms.

4. What is the best way to raise silkworms?

1. Management of silkworm cages. Silkworms are usually raised in cages, which is convenient for management and growth. Considering the fragility of silkworms, first of all, the silkworm cages must be disinfected in place. It is best to expose them to the sun for a few days after disinfection to achieve the effect of natural disinfection. Secondly, do not choose materials with strong water absorption, as silkworms prefer a relatively dry environment. Secondly, the location of the silkworm cage should not be in a place with too bright light, as this is not conducive to the growth of silkworms.

2. Feeding and management. The mulberry leaves fed to silkworms in different time periods are also different, so special attention should be paid. In order to ensure the initial development, the mulberry leaves in the early stage must be relatively fresh and tender. Silkworms do not need water when feeding, and their water source all comes from mulberry leaves, so try to feed them fresh mulberry leaves each time, and drain the water from the leaves. The feeding time is generally from 7 am to about 10 pm, with 4 to 5 feedings in between. The mulberry leaves must cover the silkworms, which is conducive to eating. The thickness is generally about 3-4 layers of mulberry leaves.

3. Environmental management. Silkworms are sensitive to light and temperature. In the early stage, young silkworms should generally avoid exposure to light. In the presence of light, the hatching process is slow and the temperature should be controlled at around 25-30℃. In the early stage after hatching, the temperature should be kept at around 30-33℃. At this time, the control of light can be slightly loose, but continuous bright light should still be avoided as much as possible. In the middle and late stages, the temperature should be controlled at around 25℃. At this time, a bright environment can be maintained occasionally, but it should still be mainly dim.

4. Precautions. First of all, silkworms are very fragile. Once diarrhea occurs, it is a very serious problem for silkworms. They must be isolated in time to avoid further impact. Secondly, the feces should be cleaned. In order to avoid harm to the silkworms during cleaning, it is recommended not to clean too many times. Generally, cleaning is done when the silkworm feces accumulate too deep. Secondly, the remaining stems of mulberry leaves must be cleaned in time to avoid harming the silkworms. Finally, the environment for raising silkworms must be kept relatively ventilated to avoid being too stuffy.
