CATDOLL : CATDOLL: How to raise silkworms (What are the methods of raising silkworms)

1. 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.

2. How to breed silkworms?

Hello,

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, and there are 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. 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.

4. How to raise silkworms?

1.

Silkworms require to be raised in a high temperature and humid environment. The suitable temperature for the growth of 1-2 year old silkworms is 26-27 degrees. You can put a plastic film on them to increase the temperature and humidity. When the silkworms grow to 3 years old, remove the plastic film.

2.

Silkworms need to be fed four times a day. The feed is usually mainly mulberry leaves to promote digestion of the young silkworms. The moisture on the mulberry leaves must be wiped clean when feeding, otherwise the silkworms will die from food overload.

3.

The silkworm beds of silkworms in the middle stage of sleep should be dry enough. Lime powder can be sprinkled on them to maintain a relative humidity of 80%. When silkworms begin to emerge, the relative humidity can be increased to 85%.

4.

During the process of raising silkworms, the silkworm room must be cleaned and the silkworm tools must also be cleaned. In addition, when picking mulberry leaves, pay attention to removing the tender heads of the new shoots to promote the maturation of the tender leaves and increase the yield of mulberry leaves.

5. Simplify the silkworm breeding method?

1. Accelerating the growth of silkworm eggs

Accelerating silkworm eggs refers to protecting the activated silkworm eggs in reasonable environmental conditions to promote the smooth development of the embryo until hatching. Since the silkworm eggs turn green the day before hatching, it is called accelerating. (Silkworm eggs are stored in a refrigerator at 5-7℃ for 3 months and then break dormancy and become activated eggs.)

Generally, the temperature of 25℃ and relative humidity of 75-80% can be used to accelerate the growth of green tea, and it can be hatched after about 10 days. Schools with conditions are best to use an automatic temperature-controlled incubator for acceleration of growth.

(1) Disinfection of instruments for accelerating greening: Use a double dish or other transparent box-shaped plastic container with a diameter of about 9 cm. After thorough washing, wipe it carefully with 75% alcohol and dry it for later use.

(2) Disinfection of silkworm eggs: Take out an appropriate amount of silkworm eggs from the refrigerator, place them on medical gauze, tie them into a small bag, soak them in 75% alcohol for 5 minutes, take them out and gently squeeze out the alcohol on the gauze, then soak them in 95% or anhydrous alcohol for 1 minute, take them out and gently squeeze out the alcohol on the gauze. Pour the silkworm eggs into a sterilized container, spread them thinly, and use clean filter paper to absorb the remaining alcohol. After the alcohol has evaporated, cover the container with the lid and fix the bottom and lid of the container with a little tape.

(3) Management of accelerating the growth of silkworm eggs: Place the sterilized silkworm eggs in an incubator that has been adjusted to a temperature of 25°C for protection. Since it is difficult to have consistent protection measures in different places after the silkworm eggs are distributed, the embryos of the silkworm eggs will develop to a certain extent during the refrigeration period, which will lead to uneven hatching. Therefore, from the 7th to 8th day after heating, close observation should be carried out. If a small number (about 1/3) of the silkworm eggs begin to turn green, the accelerating container should be wrapped with black cotton cloth or black paper to block light and keep it in the dark for about 2 days. This can inhibit the hatching of fast-growing silkworm eggs. The eggs can be opened to light on the day of harvesting to promote the simultaneous hatching of the silkworm eggs. In most parts of my country, when accelerating the growth of silkworm eggs from May to October, the natural humidity can basically meet the requirements for the development of silkworm eggs.

2. Feed production

(1) Mixed bagging: Weigh an appropriate amount of the distributed powdered silkworm artificial feed, add water at a weight ratio of 1:2.3 (1-3 years old) or 1:2.1 (4-5 years old), and stir to mix evenly. Weigh an amount of the mixed feed equivalent to 50 grams (1-3 years old) or 150-170 grams (4-5 years old) of powdered feed and put it into a food plastic bag. Flatten the feed by hand or with a stick to the area corresponding to the inner diameter of the breeding container (22×16×5 cm), and remove the air in the bag as much as possible. Fold the excess part of the bag opening more than 2 times to isolate the air inside and outside the bag, and use tape to properly fix the folded part. Wrap the bagged feed with white paper or newspaper (2-3 bags can be used in a bag) and steam and sterilize.

Depending on the bottom area and shape of the feeding containers in different places, the amount of feed bagged and the number of silkworms to be raised can be adjusted accordingly.

Generally, a silkworm needs to eat 5 grams of dry feed during the 1st to 5th instar. Taking into account factors such as feed residue loss, 6-7 grams of feed should be prepared for one silkworm.

(2) Steaming and sterilizing: You can use an ordinary pot or a pressure cooker for sterilization, but you should note that since the bag mouth is not sealed, the feed can only be steamed in a steaming rack or a steamer, and cannot be boiled in water. Be careful not to overfill the bag. Also, since the feed will expand after steaming, the residual air in the bag will expand more seriously. Be careful not to block the air outlet of the pressure cooker and cause an accident. Steaming and sterilizing time: Continue steaming for 45 minutes after the water in an ordinary pot boils, and continue steaming for 25-30 minutes after the water in a pressure cooker boils. After cooling, take out the feed together with the newspaper, put it in a plastic bag, and store it in a refrigerator at 5-7℃ for later use (can be stored for 10 days).

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.

7. 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.
