1. 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.

2. Top ten tips for raising silkworms?

Silkworm breeding method

1. Do a good job in disinfection and disease prevention

Because the interval between silkworm breeding in summer is short, pathogens are fresh and large in quantity, and are easy to infect, we should pay attention to environmental sanitation and thoroughly disinfect the silkworm room and silkworm tools. You can spray disinfectant first, then clean and wash them. When spraying, pay attention to the dosage and spray all the surfaces. Strictly implement the "three disinfection principles" (that is, thoroughly disinfect before silkworm breeding, continue disinfection during silkworm breeding, and disinfect immediately after silkworm breeding), and carry out disinfection and disease prevention throughout the entire silkworm breeding process.

When harvesting leaves for summer silkworms, attention should be paid to the safe interval of pesticide application. Mulberry leaves from areas where pesticides are applied must be harvested and fed after the residual period has expired. Only after they are proven to be non-toxic can leaves be harvested for feeding. Summer silkworms should be protected from flies and rats to avoid losses.

2. Adjust the room temperature for silkworm rearing

According to the characteristics of summer climate, take corresponding measures to adjust and improve the silkworm breeding environment. In hot and humid weather, pay attention to ventilation, and cool down and moisturize when it is hot and dry. Plastic film can be used to cover the young silkworms, which can keep warm and moisturize, which is conducive to the healthy development of silkworms. In the adult silkworm period, choose a tall, spacious and well-ventilated house to prevent stuffiness. Plant trees and build a pergola around the silkworm house to reduce radiation.

3. Do a good job in mulberry leaf management

The quality of mulberry leaves is directly related to whether the summer silkworm harvest is good or not. We should strengthen the fertilization and pest control of mulberry trees to promote the growth of mulberry trees. During the young silkworm period (1 to 3 years old), it is key to pick the leaves that are ripe, with the color being pure green and soft to the touch as the standard. When collecting mulberry leaves for ants, you should choose mulberry leaves that are ripe and tender, and avoid using leaves that are not exposed to enough sunlight, old leaves, wilted leaves, diseased and insect-infested leaves, and mulberry leaves contaminated by pesticides. The leaves for summer silkworms should be picked in the morning before the dew dries or in the evening. Leaves must not be picked in the middle of the day (except on rainy days). The picked mulberry leaves should be picked and transported quickly to prevent the mulberry leaves from emitting moisture and withering. Pay special attention to not stacking mulberry leaves too high or too thick to prevent them from rotting.

4. Do a good job in feeding management

First, the transportation of silkworm eggs. When transporting silkworm eggs, do not pile them up or pile them up, and try to avoid contact with high temperatures. The transportation of silkworm eggs should be carried out in the morning and evening, and they should be spread out in time after being brought back to prevent accumulation and heating. When distributing silkworm eggs, try to do it in the morning and evening. Silkworm eggs should not come into contact with pesticides and all harmful gases to prevent silkworm poisoning.

Second, feed the young silkworms. Plastic film can be used to cover the silkworms. Silkworms grow and develop quickly, so the area of ​​silkworm seats should be expanded in advance to prevent them from being crowded and hungry. Disinfect the silkworm bodies and silkworm seats with fresh lime powder or 2% effective chlorine anti-stiffness powder every day. Add 500 times diluted silkworm disease sterilization spirit, Yijiling, and Kejunxing to feed the young silkworms when they wake up. Use 0.3% effective chlorine to soak or spray the leaves for disinfection, dehydrate, and dry them before feeding them.

Three-catch adult silkworm rearing. During the period, three sparse should be achieved: the silkworm racks in the silkworm room are sparsely connected, the silkworm foils on the silkworm racks are sparsely placed, and the silkworm heads in the silkworm foils are sparsely placed. This is conducive to ventilation, lowering the temperature, and ensuring that the silkworms are fully fed. During the adult silkworm period, especially during the hot and humid period, the silkworm litter should be removed frequently to keep the silkworm seats clean and dry. During the adult silkworm period, labor-saving silkworm rearing should be implemented. During the adult silkworm period, 300 times the liquid of fly-killing tablets should be sprayed on the silkworm bodies and 500 times the liquid should be added to the food to prevent maggots from harming them.

Fourth, cluster management. In order to reduce labor costs, it is advisable to adopt automated cluster technology. The specific method is: when the silkworms develop evenly and 5-10% of the silkworms are mature, use 4-6 pieces of Chuanto for each silkworm seed and mix 20-30 jin of mulberry leaves with cold boiled water (4-6 pieces with 1-1.5 jin of water), feed the silkworms at 10-12 pm, and no longer feed mulberry leaves. At 10-12 am the next day, sprinkle some straw or silk nets on the silkworm seat, and put plastic clusters or square clusters on the silkworm seat to let the mature silkworms automatically cluster and make cocoons. After clustering, strengthen the ventilation and dehumidification of the cluster room (use electric fans to dehumidify if conditions permit), so that the cluster room, cluster tools, and environment are dry, improve the yield and quality of silk cocoons, and ensure stable and high yields of summer 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.

4. 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.

5. 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.

6. 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.
