Can mulberry silkworms be raised in winter, and how long can mulberry seedlings be raised

Yes, you have to create an environment for us to adapt to.

Mulberry seedlings can be raised after 2 years of planting.

Mulberry seedlings are planted mainly in winter and early spring, and are generally planted in spring. It is understood that the new mulberry seedlings can bear fruit in April and June of the second year after grafting, and if it is silkworm raising, as long as the mulberry seedlings have long leaves, they can basically be picked to feed the silkworms, so after the mulberry seedlings are planted, the silkworms can be raised in the second year.

Mulberry seedlings should be planted in the second year after planting silkworms, and seedlings with strong growth and no damage should be selected for planting, which is conducive to improving the survival rate, and then the root system should be pruned and sorted, and the excessively long root system should be cut off, and planted in the soil after disinfection treatment.

Mulberry seedling planting precautions:

1. Mulberry seedling selection.

To choose healthy and strong seedlings, remove the weak and diseased mulberry seedlings, the rhizome of the general mulberry seedlings should reach more than 7 mm, which is conducive to improving the survival rate of mulberry seedlings.

2. Transportation matters.

During the transportation of mulberry seedlings, it is necessary to avoid heavy pressure or sun and rain transportation, and after the mulberry seedlings are transported to the destination, they should be planted or planted immediately. If it is found that the mulberry seedlings are dry, the seedling roots can be transported to the destination into the mud water, kept for 12 24 hours, and then placed in a cold place for later use, so that the seedlings can absorb an appropriate amount of water and improve the survival rate of planting.

3. Planting time.

In the middle and lower reaches of the Yangtze River, planting is generally best carried out in mid to late December in winter. However, due to the cold in the northern region, the soil freezes early, so transplanting should be carried out before the mulberry trees germinate after the soil thaws.

4. Planting matters.

Spring planting requires false planting of seedlings, and protect the root system to avoid dryness, mildew and frostbite, and timely watering and irrigation to ensure survival. Before planting mulberry seedlings, the root system can be pruned and sorted, the excessively long roots or the roots that are curled and twisted together can be cut off, and then put into 2% 5% lime water, soaked for 5 10 minutes, which can be sterilized and disinfected, and is also conducive to improving the survival rate of mulberry seedlings.

5. Post-planting management.

In areas with convenient drainage and irrigation, it is necessary to water appropriately according to the dry soil and local climatic characteristics, and if the rainfall is sufficient, it is also necessary to pay attention to drainage to avoid waterlogging. It can also be carried out appropriately on the ground topsoil of the mulberry orchard, leveling and hoeing and removing weed waste, etc., to ensure the looseness and air permeability of the soil, which is conducive to the normal respiration of the mulberry seedling root system.

Mulberry picking and silkworm farming are generally in spring and summer.

Silkworm raising is an important skill created by the working people of ancient China, and the method of planting mulberry and raising silkworms is said to have originated from the wife of the Yellow Emperor. The ancestors of the silkworm were considered to be wild silkworms (b mandarina), which are almost indistinguishable from silkworms in morphology, and can naturally cross with silkworms to produce offspring when they grow up.

There is a silkworm breed called "Qingbai", which is said to have been crossed from wild silkworms and domestic silkworms. The traits of other silkworms are obviously transmitted from wild silkworms. The number of chromosomes is n=27 for wild silkworms and n=28 for domestic silkworms, and it is believed that domestic silkworms are produced by cutting one chromosome of wild silkworms into two in the process of evolution.

Summary. Hello, glad to answer for you. Silkworms are generally raised for 45 days.

Generally, the greening stage is 10-11 days, and the larval stage is about 25 days. Specifically: 4-5 days for the first instar; 3-4 days for the second instar; 4 days for the third instar; 6 days at the fourth instar; 7-9 days at the fifth instar; period 14-18 days; The moth stage is 3-5 days.

How many days can you keep it with a special breeding tank?

Hello, glad to answer for you. Silkworms are generally raised for 45 days. Generally, the greening stage is 10-11 days, and the larval stage is about 25 days.

Specifically: the first age of the old sales is 4-5 days; 3-4 days for the second instar of the tour; 4 days for the third instar; The period of the fourth instar eggplant is 6 days; 7-9 days at the fifth instar; period 14-18 days; The moth stage is 3-5 days.

Hello, glad to answer for you. The breeding cycle of the silkworm is generally about 40 days, and its development is related to temperature, humidity, food, etc. Generally, the greening stage is 10-15 days, and the larval stage is about 25 days.

The specific instar period is 4-5 days; 3-4 days for the second instar; 4 days for the third instar; 6 days at the fourth instar; 7-9 days at the fifth instar; Pupal stage: 14-18 days; The moth stage is 3-5 days.

Silkworms are generally frozen to death at temperatures below 8 degrees. Silkworms can be raised all year round, but usually in spring and autumn, when the temperature is between 20 and 30 degrees, it can grow normally, and mulberry leaves can only be above 15 degrees, if raised in other seasons, can only be fed some other feed.

If it is farmed in the summer, it needs to be cooled down so that it does not suffer from heat stroke and repentance and death. In winter, it is necessary to keep warm, and this animal can easily freeze to death.

Precautions for sericulture

Prevention of pesticide poisoning. Do not spray organic pesticides such as insecticide in the silkworm room and the farmland near the mulberry field during the silkworm season, its odor effect will lead to silkworm poisoning.

Mosquito coils or mosquito killers and insecticides are prohibited in the silkworm room. When used in a house adjacent to the silkworm room, the doors and windows of the silkworm room should also be closed to prevent silkworm poisoning. Screen doors and windows should be installed in the silkworm room to prevent flies from entering the silkworm room to harm the silkworms, and add silkworm emulsion or spray silkworm body to kill flies and maggots.

Before raising silkworms, the rat hole should be blocked, the silkworm frame should be kept at a certain distance from the wall, and lime powder or silkworm medicine should be sprinkled around the foot of the silkworm frame to prevent the rats from climbing. To raise silkworms, we must do a good job of drug extermination. In summer and autumn, the temperature of silkworm breeding is high, so it is necessary to open doors and windows to strengthen indoor ventilation.

Mulberry leaves are sprayed with clean water, and the indoor electric fan blows the breeze, which is also conducive to indoor cooling.

If the diseased silkworms are found, they should be cleaned up in time, put into a disinfection basin containing bleaching powder solution or lime slurry, and it is forbidden to feed the diseased silkworms to prevent the spread of pathogens and pollute the environment. Silkworm sand contains a large number of pathogens, so it should not be spread around the silkworm room, but should be concentrated in the wild or put into the manure pit to prevent the spread of pathogens.

Hello, it is a pleasure to serve you and give you the following answer: Yes. Tussah silkworms belong to the silkworm family of the Tussah family and are a type of silkworm that is resistant to bacteria from plant seeds.

They feed on the leaves of the oak tree, and the mulberry leaves are also the food of the silkworms, so the mulberry leaves can raise the silkworms. Steps to feed silkworms: 1. Prepare materials:

1. Mulberry leaves: Collect fresh mulberry leaves, wash them, dry them in the sun, and put them in containers. 2. Silkworm:

Fresh silkworms are collected from oak trees. 2. Silkworm raising skills: 1. Place the silkworms:

Put the silkworms into the container, keep the temperature of the container at about 30, and add mulberry leaves to the silkworms every day to ensure that the silkworms have enough food to eat. 2. Add grain: Every once in a while, add some plant seeds to the container, so that the silkworms can eat the seeds to increase nutrition.

3. Pay attention to cleaning: clean the container regularly and remove the dirt in the container to keep the container clean so as not to pollute the silkworm file. 3. The knowledge of feeding silkworms:

1. Tussah silkworms like a warm, moist and clean environment, if the environment is too humid, it may lead to the development of Tussah silkworm virus, so pay attention to control the temperature and humidity of the container. 2. The food of the silkworm is diversified, not only can eat mulberry leaves, but also seeds, fruits, vegetables, etc., but you should be careful not to eat poisonous food, so as not to affect the health of the silkworm. 3. The reproduction of silkworms is very fast, and eggs are generally laid every month, so it is necessary to pay attention to controlling the number of silkworms to avoid too many silkworms.

Hello, it is a pleasure to serve you and give you the following answer: Yes, mulberry leaves can raise silkworms. The steps to raise silkworms are as follows:

1.Prepare mulberry leaves: Mulberry leaves are the main food of the silkworms, and fresh mulberry leaves should be selected and chopped so that the silkworms are easier to eat.

2.Prepare the container: Tussah silkworms need a container to hatch, plastic containers or glass containers can be used, the container should have enough space so that the tussah can move freely.

3.Add mulberry leaves: Place the chopped mulberry leaves in a container so that the silkworms can eat them freely.

4.Add the silkworms: Place the silkworms in a container and let them roam freely in the mulberry leaves.

5.Provide water to the silkworms: Silkworms need water to keep them moist, and you can use damp cotton or a damp rag to provide water.

6.Provide temperature to the silkworms: The silkworms need the right temperature to hatch, and room temperature or a warm bulb can be used to provide the temperature.

7.Regular cleaning: Clean the container regularly to prevent the silkworms from being attacked by germs.

The above are the steps of raising silkworms, in the process of raising silkworms in withered silver oranges, we should pay attention to the temperature and humidity of the silkworms, and clean the containers regularly to ensure the health of the silkworms.

1. Pick mulberry leaves. Mulberry leaves are the food of silkworm babies, and the silkworm babies should be prepared 2-4 times a day on the leaves, and the fresh young leaves should be picked when feeding, and the mulberry leaves should not have dew and keep them dry.

2. Put it in a cardboard box. The baby silkworm comes out of the egg and becomes a larvae, at this time it is necessary to carry out box culture, that is, the larvae and baby silkworm are put into a cardboard box for easy management.

3. The box should be pierced. The box is not breathable, so it is necessary to pierce some holes for the box above, that is, slowly pierce some holes with nails to facilitate ventilation and supply oxygen. and place in a dark place, away from direct sunlight.

4. Timely upper leaves. Feed with fresh tender mulberry leaves, generally one handful at a time, not too much, too much, not finished, the leaves will wither, which is not conducive to the growth of silkworm babies.

5. Pay attention to observation. After the leaves are finished, it is necessary to pay attention to observation, and find that there are individual sick silkworm babies to pick out in time. There are black or yellow spots on the silkworm baby, which is sick or diseased, and can be smeared with some salt water or liquor to disinfect and cure the disease.

6. Drive away ants. After picking the mulberry leaves, it is necessary to see if there are ants, ants are the number one natural enemy of the silkworm baby, once there are ants, drive them away in time, the method is to use camphor or mint leaves to put around the silkworm baby box, so as to facilitate the invasion of ants.

7. Pick out the tiger silkworm. When the body of the silkworm baby is white, the tiger silkworm can be identified, the shape of the tiger silkworm is large, like a big green worm, the color is blue, some are gray, and it is cleaned up in time after being found, the tiger silkworm harms the silkworm baby, 1 snatches the food, 2 bites other silkworm babies, which will cause damage to the silkworm baby.

8. Divide the box in time. Silkworm babies are bigger, they will compete for territory, at this time it is necessary to divide the box for the silkworm babies in time, and the best method of dividing the first hand is to divide according to the size of the body. The big ones should be divided into 2-3 boxes, and the small ones should be together, 1 box can be raised, which is easy to manage and facilitate the later cocooning.

9. Take out the silkworm feces. Silkworm babies eat a large number of mulberry leaves, they have to discharge feces, the color is green, some wet, can be dried, dried, and used for another purpose. Silkworm feces are also treasures, pay attention to collecting them.

10. Continue feeding. After taking out the feces of the silkworm baby, continue to feed, the number of times becomes 2 times, once in the morning and once in the afternoon, because the silkworm baby has grown up, and there are many silks in the body ready to spin silk. Silkworm babies began to eat less.

The color is white, clean white, which means that the cocoon is about to form.

11. Start to form cocoons. The color of the silkworm baby is white, and the mulberry leaves are eaten less, the leaves can be left once a day, and the cocoon begins to form a cocoon, the silkworm baby chooses a place, and the corner of the general box is more, it is a cocoon at night, and the silkworm baby begins to spin silk, and the cocoon is self-bound.

12. Comprehensive treatment. To dispose of the cocoons, take off the cocoons that have been knotted, put them in a bag, accumulate them, and sell them for money. Disposal of feces left by baby silkworms.

At this time, after the silkworm baby cocoons, a lot of feces are produced, and the color is black.
