What problems need to be paid attention to in sericulture? What do you need to pay attention to when

Silkworm sand contains a large number of pathogens, which cannot be dumped at will, let alone spread around the silkworm room, and should be concentrated in the wild or put into the manure pit to prevent the spread of pathogens. High temperature in summer and autumn, pathogens multiply quickly, pay attention to planned leaf picking, timely transportation of leaves, reasonable storage of leaves, can not be piled up too thick, to prevent baking fever deterioration and induce silkworm disease. The mulberry storage pond should be disinfected once at each age to eliminate germs, and mulberry leaves should not be fed overnight.

When the silkworm has just hatched from the egg, you should be especially careful with it, feed it with a relatively tender mulberry, and use a very soft brush to move it when changing mulberry leaves, and pay attention to the strength; Put it in a cardboard box, or a small sieve for sieving rice, and if you use a sieve, put some paper on the bottom of the sieve. Sometimes the mulberry leaves are too dry, and if you are not careful, you will leave the silkworms on the mulberry leaves to be discarded in the process of changing the mulberry. When you are young, it is difficult to raise a little, but it is easier to do when you grow up.

When it is about to form cocoons, take some wheat stalks and tie them into the shape of branches.

Silkworms must pay attention to feeding in the larval stage, prepare food mulberry leaves (lettuce leaves can also be used), be sure to wash and dry (or wipe dry) with water before feeding, do not feed silkworms with yellowed and rotten leaves, otherwise silkworms will be poisoned or diarrhea. In order to prevent the surplus leaves from wilting quickly, you can put it in a plastic bag and tie the bag tightly and put it in a cool place.

Mulberry leaves should be fresh, you can also collect a plastic bag at a time, use several sheets a day in parts, and sprinkle the rest with some water in the refrigerator to keep them fresh. The leaves will have a certain amount of dust, which can be washed and dried, and must be cooled and dried, otherwise the small silkworm or the big silkworm will have diarrhea after eating, and maybe it will die.

When the silkworm grows to a certain size, it will spin silk to make a cocoon. The silkworm body is transparent and shiny, no longer eats mulberry leaves, climbs to the side, and its head is raised from time to time, dangling around. At this time, you should quickly take out the silkworm and put it in the square made of paper strips, and finally cover a thick paper on the grid as a cover, so that the silkworm can spin silk in the grid to make cocoons.

After the silkworm makes the cocoon, it is necessary to wait for the silkworm moth to come out of the cocoon, and the general time is mostly in the early morning. After the silkworm moth emerges from the cocoon, the male and female silkworm moths will mate. If the cocoon moth is large and the number of moths is small, and they are all female or male, they cannot mate and wait for death in vain.

Therefore, it is necessary to pay attention to the silkworm moths that have just emerged from the cocoon to get together so that they can mate in time.

In summer and autumn, the temperature of silkworm raising is high, in the morning to spray well water in the silkworm room, hang wet cloth or straw curtains, close the doors and windows during the day to prevent the heat from flowing into the room, and the temperature is low at night, to open the doors and windows all night. 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 the disinfection basin containing bleaching powder solution or lime slurry, and the diseased silkworms should not be littered, and the diseased silkworms should be prohibited from feeding livestock and poultry to prevent the spread of pathogens and pollute the environment.

Silkworms do not eat or move during the dormant period, and mainly rely on the nutrients absorbed by eating mulberry before sleep to maintain life activities. So be sure to eat and sleep. If you stop giving mulberry too early, it will cause starvation, and the hungry silkworm is weak, has poor resistance, and is prone to disease. ‍‍

Market, do you have a cocoon station or company where you buy silkworm cocoons, silkworms will be feathered about 10 days after the cocoons are completed, if not, they will be scrapped! Silkworms are sensitive to pesticides and fluoride and are prone to poisoning.

It doesn't matter if you're just raising a few heads to play around!

The main temperature, dry and wet, disinfection, the three main points are in place, there is no big problem. Careful life has to be done by careful people

Silkworm raising is disease-free and high yield, the first pass of disinfection and disease prevention, mulberry leaf silkworm seed is the foundation, and the key to feeding technology.

My goal is to make a lot of money with 5 yuan per catty.

Due to the downturn last year, many silkworm farmers have now given up breeding to work!

The mulberry leaves fed to the silkworms must be dry, and if the surface of the mulberry leaves is dusty and needs to be washed, they should also be dried after washing.

The temperature is high in summer, the mulberry leaves will be yellow and deteriorate after being stacked for a long time, the climate is dry in autumn, the mulberry leaves picked up, will dry up and harden after staying for a long time, you can beat a pound of water and add 5 ml of fermentation broth according to the reputation, which is used to spray the mulberry leaves wet, and then put the mulberry leaves into woven bags or pile them on the ground, cover them with plastic sheets, and keep them for 24 hours and still fresh green as ever.

Mulberry leaves should be reasonably collected, transported and stored. Try to do the morning or evening leaf picking, with the picking, loose fast, the collected mulberry leaves shake loose and put into the mulberry storage pond or mulberry storage room, reasonable storage, to prevent wind blowing or accumulation of heat and deterioration, resulting in waste of mulberry leaves. Bixiang.

1. Regulate the temperature: maintain the temperature at about 20-25 in the early stage of growth. 2. Provide light:

Place in semi-shade to allow the baby silkworm to receive natural light. 3. Feeding: chop the fresh mulberry leaves and spread them around the silkworms.

4. Clean up the residue: clean up the remaining food scraps and replace the silkworms with new cartons.

1. Adjust the temperature

Silkworms are more sensitive to temperature, and in a warm environment is conducive to embryonic development, so it is best to control the temperature between 20-25, and can not be lower than 20, if the temperature of breeding is too low, the silkworm baby will stop growing.

2. Provide light:

In the process of raising silkworms, it is necessary to provide it with suitable light, not to put it in the shade for a long time, otherwise it will affect the appetite of the silkworm, when the weather is fine, you can put the silkworm in the semi-shade, so that it receives natural light.

3. Feed feed

The stomach and intestines of silkworms are relatively fragile, so try to choose relatively soft leaves when feeding it food, such as mulberry leaves and cabbage leaves, and pay attention to chopping the leaves into small pieces to facilitate the silkworm baby to eat, so as not to be difficult to swallow.

4. Clean up the residue

In the process of raising silkworm babies, we should pay attention to the hygiene in the box, and clean up the leaves and feed accumulation after they are found, so as to avoid breeding bacteria after rotting, resulting in diarrhea and severe disease infection.

You can make checkered clusters in cardboard boxes, and the baby silkworms will climb into them to form cocoons on their own.

The silkworm baby no longer eats mulberry leaves and reeds, its body will begin to shine, and it will crawl everywhere to find a suitable place, and when its stool turns yellow, it is about to form a cocoon.

At this time, you need to put something that can be supported in the silkworm box to help the silkworm baby make a cocoon and give the silkworm baby a suitable environment to form a cocoon. In the absence of something to support, the silkworm baby will not spin silk, then it will not form a cocoon, and will only "suffocate" itself in the end.

Silk spinning habits of silkworms.

According to the living habits of silkworms that eat and sleep, sleep and eat, people compare silkworms to babies who have not been born for a long time, and affectionately call it "silkworm Yuling with babies". In fact, the sleep of the silkworm is not a passive rest, but a way for it to renew itself as it grows.

The silkworm has to shed its skin four times in its life, and once it sheds its skin, it grows its body once, and each time it sheds its skin in sleep. When silkworms sleep, their bodies are not calm. It turns out that the cranial nerves of silkworms secrete a brain hormone. Brain hormones, in turn, enable the body to produce juvenile hormones and peeling hormones.

The ability of larval hormone is to make the silkworm still maintain the appearance of the larvae after shedding the skin, inhibit the appearance of adult characteristics, and keep the silkworm young; The function of describing hormone is to accelerate the maturation of larvae. These two are opposites and unified, promoting the growth of silkworms.

When the silkworm reaches the middle of the fifth year, the secretion of juvenile hormone in the body Wang brother basically stops, the function of peeling hormone is strengthened, and the silkworm matures quickly.
