CATDOLL : CATDOLL: How to raise silkworms well (How to raise silkworms well)

1. 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.

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

When I was a child, every household in my town raised silkworms every year. First, we managed the mulberry trees well to ensure that there were enough mulberry trees for the silkworms to eat from March to November. Second, we cleaned up the silkworm feces and mulberry leaves and disinfected the silkworm room every time the silkworms spit out silk and formed alkali. Disinfection with lime powder must be in place to prepare for the next silkworm sleep from the silkworm eggs to each silkworm sleep, that is, the silkworms sleep and shed their shells to grow up again. During this period when the silkworms are not sleeping and wake up, the silkworms that are obviously much smaller than others are picked out in time to ensure that each silkworm is of uniform size. After the last sleep, the silkworms grow the fastest and eat the most mulberry leaves in their lives. We feed the silkworms with enough mulberry leaves. At this time, the silkworms' bodies grow from the size of toothpicks to almost the size of fingers. When their bodies change from light blue to golden yellow, they stop eating mulberry leaves and start spinning silk. When some silkworms turn golden yellow, they are fed with the last meal of mulberry leaves with a ripening agent to ensure that each silkworm spins silk at the same time.

3. What is the best way to raise silkworms?

1. Temperature regulation

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. Feed properly

Silkworms need to be fed four times a day. The feed is usually mainly mulberry leaves, which should be cut into small cubes before feeding to promote digestion. The moisture on the mulberry leaves should be wiped clean when feeding, otherwise the silkworms will die from food overload.

3. Sleep protection

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. Notes

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.

4. How to raise silkworms well?

Method of raising silkworms: prepare a large amount of mulberry leaves, find a plastic box with a lid, cover it with blank draft paper, put the silkworms into the box, cover it with mulberry leaves, and half-cover the box.

Silkworms grow very fast, so you need to pick a lot of mulberry leaves every day and feed them to the silkworms in time.

The silkworm will not eat mulberry leaves when it is molting, but it will continue to eat mulberry leaves 4-5 hours after molting. After molting 5 times, it will eat a lot of mulberry leaves, and when it raises its head, it means it is about to make a cocoon. Move it to another wide box.

After a week, cut off the cocoons and move them to a box covered with napkins. Cover it with a lid. After two weeks, it will come out and you can let it pair up on the napkins and produce seeds.

If you want to hatch a second batch, keep them at room temperature and they will be born in 3 weeks.

If you don't want it to hatch, put it in a dark place out of the sun. Don't put it in the refrigerator, otherwise it will freeze to death.

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.

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. 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.

Additional information:

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.

7. How to learn the complete set of techniques for raising silkworms?

1. To raise silkworms, you must first buy silkworm seeds, which are silkworm eggs. This product has the ability to hatch silkworms. Every spring, when the temperature remains around 20 degrees, silkworms will hatch from silkworms.

2. After the silkworms hatch, you need to pick mulberry leaves to feed them. The chewing ability of silkworms is not that strong, so you should choose relatively tender mulberry leaves. There should be no water or pesticides on the mulberry leaves.

3. Silkworms can be raised in paper boxes. If the scale is larger, they can be raised in special bamboo boxes, which must be breathable, hygienic and clean.

4. Raising silkworms has relatively high requirements for the environment. There must be no fumes, no mosquitoes, no mosquito coils, no spraying of pesticides, and no dust. Otherwise, the survival rate of silkworms will be affected.

5. The process of raising silkworms is very hard. Silkworms need to eat mulberry leaves day and night, and as they grow older, the amount of mulberry leaves they eat increases.

6. Silkworms usually spin cocoons in about a month. Before spinning cocoons, we need to build a frame and let them go up the mountain. It will take about two or three days for the silkworms to spin a snow-white cocoon.
