How to raise silkworms, please help, silkworm raising techniques and methods

Do you breed in large quantities or do you keep them for fun?

1. Mulberry leaves are the most suitable natural food for silkworms, in addition to mulberry leaves, silkworms can also eat lettuce leaves, elm leaves, grape leaves, lettuce leaves and other green leaves.

2. Silkworms can be cultivated directly in cartons, which need to be kept clean and dry, and cannot contain water. When raising silkworms in a small space, do not put too many mulberry pants and filial piety leaves at one time.

The small silkworm under the centimeter needs to eat the most tender leaves, while the large silkworm also needs to eat an appropriate amount of old leaves on the basis of the young leaves to promote silking. Pay attention to wipe off the moisture on the mulberry leaves every time you feed them, and the mulberry leaves that are not fresh enough should be cleaned up in time.

4. According to the size of the body, it is best to divide the silkworm babies into boxes to prevent them from fighting for territory. In addition, ants will eat silkworms, and when they are raised, they need to observe the environment and find that the ants must be cleaned up in time. Drafting.

Technical regulations and key points of silkworm breeding.

1.Two days before receiving silkworm seedlings, the silkworm house should be thoroughly disinfected, cleaned and disinfected.

2.In silkworm raising, wash hands and disinfect before work, store special shoes for local fortification, and pick up sick and weak silkworms in time; The remnants of the silkworms after ripening should be kept away from the silkworm house, and it is best to burn them in batches.

3.On the first day, the silkworm seedlings were brought back, and a layer of fresh lime was sprinkled on the floor of the silkworm house, and each silkworm seedling was evenly sprinkled into a furrow shape of about 22 square feet. After the silkworm seedlings are fed to the ground, 15 minutes before feeding the silkworms, sprinkle a layer of anti-stiff powder on the silkworm seat (1 package of zombie killing, 3 catties of lime powder can be stirred), and then cut the mulberry leaves into 10 cm long and short evenly fed to the first mulberry leaves on the silkworm net.

4.From the next day, 16 minutes before feeding the silkworms every morning, a layer of lime is sprinkled on the silkworm seat and then the silkworms are fed.

5.On the third day, when the sleeping silkworms begin to sleep after about two days and ten hours, they are fed to chopped mulberry leaves until more than 95% of them are asleep.

6.On the morning of the fourth day, sprinkle lime (no anti-stiff powder) to raise the green, and remove the weak sleepless silkworms.

7.On the fifth day, the mulberry is released (the first mulberry at the age of 5). When the sleeping silkworm has passed 22-24 hours, 98% of the silkworms have taken off their old skin, raised their heads and swayed left and right, and their mouths are black-brown, first sprinkle anti-manuscript skin stiff powder on the silkworm seat and cover it with a rubber net, and feed the knife to chop the mulberry on the net for about 10 minutes, and after 2-3 hours in the second mulberry (chopped mulberry), that is, change the and divide the bed.

8.On the morning of the sixth day, the seats were expanded, the seats were evenly distributed, and then the lime was sprinkled for 15 minutes and then given to the mulberry.

9.The seventh to ninth day silkworm is in the peak feeding period, is the key moment to increase the production of silkworm cocoons, to give enough food, generally divided into morning (6 o'clock), noon (2 o'clock), night (9-10 o'clock) to give three mulberry, night than daytime more.

Second, three into mulberry, vertical each time to cut back the mulberry or to mulberry before the mulberry must loosen mulberry to disperse the heat. Mulberry should be stored and covered with film. Open convection windows before and after the silkworm house to strengthen the ventilation, heat and baking of the silkworm seat.

10.The tenth Yujing Peng Tianjian saw that there were 5% ripe silkworms, spraying peeling hormone at 10 o'clock in the evening (spraying according to the master's requirements), and then feeding the appropriate amount of unripe silkworms to all ripe silkworms.

11.On the eleventh day, ripe silkworms (transparent, do not eat mulberry, climb on mulberry leaves and shake their heads and spin silk) can pick up the silkworms, and put 6 catties of ripe silkworms in each plastic cluster (can make more than 3 catties of cocoons), and build into the word "eight". The upper place should be ventilated and dry, the indoor fan should be opened to drain the moisture, and the cluster should be regularly raised and lowered 2-3 times after the upper part of the oven.

12.On the thirteenth day (the second day of the silkworm), pick up the tufted silkworms in time and put them on again, and pick up the dead ones to prevent pollution of the cocoons.

13.On the sixteenth day, when the pupa is yellowish-brown, it is advisable to pick cocoons. Actions should be done with care. Good cocoons, lower cocoons (fine cocoons, deformed cocoons, double palace cocoons) are packaged separately and shipped in bamboo baskets**.

Silkworm festival method:

Under normal circumstances, 15 kg of mulberry leaves are required for every 1 kg of silkworm cocoons produced. After taking measures to save mulberry, each silkworm seed can save about 50 kg of mulberry, and the production and quality of silkworm cocoons can not be affected at all. Its economizing measures are:

1. Mulberry leaves should be reasonably collected, transported and stored. Try to pick the leaves in the morning or evening, and transport them with the picking, and loosen them quickly. After the collected mulberry leaves are shaken and loosened, they are put into the mulberry storage pond or mulberry storage room, and stored reasonably to prevent the wind from blowing or accumulating heat and deterioration, resulting in the waste of mulberry leaves.

2. Prevent mulberry leaves from withering. In the young silkworm stage, kang bed (room) and plastic film are used to cover and breed, so as to facilitate heat preservation and moisturizing, so that mulberry leaves remain fresh. After feeding the silkworms during the silkworm period, the doors and windows should be closed appropriately, and about 70% of the mulberry leaves should be eaten away, and then the doors and windows should be opened for ventilation, which can effectively prevent the mulberry leaves from withering.

Ensure the temperature of the silkworm room. The suitable temperature of large and small silkworms is respectively, and within the suitable temperature range, the appetite is strong, the residual mulberry leaves are reduced, and the conversion rate of leaf filaments is improved.

Promote less return education and strip mulberry education. Labor-saving silkworm breeding technologies such as small silkworm plane three-dimensional one-day breeding, all-age two-time breeding, and large silkworm strip mulberry breeding not only improve the efficiency of silkworm raising, but also help silkworms eat mulberry, saving about 5% of mulberry leaves compared with ordinary breeding.

It is planned to use mulberry and ration mulberry. According to different silkworm periods, the standard amount of mulberry is formulated by age, day by day, and back by year, so that "silkworms are full of food and do not waste, and mulberry is not hungry". At the beginning and end of each instar silkworm, the amount of cannibalization mulberry decreases, and the leaves should be fed in an appropriate amount.

During the peak feeding period of the 5th instar silkworm, the silkworms should be fully fed, but the maximum daily mulberry consumption should be controlled within 110 kg.

Ecdysone is added. Silkworms are ripe about 5%, each seed uses 1 ecdysone, 25 kg of water, mix 20 kg of mulberry leaves, once the silkworms are eaten, can promote the silkworms to mature together, each seed can save about 10 kg of mulberry leaves.

Prepare tools, have good silkworm raising skills, and give them mulberry leaves...

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

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 fresh young leaves should be picked when feeding, and 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. The silkworm baby is bigger, it will compete for territory, and then it is necessary to divide the box for the silkworm baby in time, and the best division is according to the size of the body. The large ones should be divided together, which can be divided into 2-3 boxes, and the small ones 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.

1. Breeding site: When breeding silkworms, it is necessary to establish a silkworm house away from residential areas. 2. Disinfection treatment:

Before putting silkworms, potassium permanganate should be sprayed into the site for disinfection. 3. Feeding management: Feed mulberry leaves twice a day to ensure that mulberry leaves are healthy and dew-free.

4. Inspect the site: pick out the weak silkworms and dead silkworms in time to avoid infection.

1. Breeding site

When breeding silkworms, it is necessary to choose to establish silkworm houses far away from residential areas and industrial areas, and air conditioning and lighting should be installed inside the silkworm houses, so as to facilitate the regulation of indoor temperature and light brightness, and ventilation equipment should be installed in the silkworm houses, which can make the air circulation inside and outside, which is conducive to the reproduction and development of silkworms.

2. Disinfection treatment:

5-7 days before breeding silkworms, it is necessary to thoroughly disinfect the silkworm room and silkworm tools, first spray clean water into the silkworm room, wash the dirt and so on, and then prepare potassium permanganate or bleaching powder into an aqueous solution, and then place it in the silkworm room and close the doors and windows for fumigation, so that the infection rate of the liquid Tanzan silkworm is reduced.

3. Feeding management

Mulberry silkworm staple food is mulberry old buried Zheng leaves, when breeding mulberry silkworms, you need to feed mulberry leaves twice a day, you can choose to do it every morning and evening, and when feeding mulberry silkworms, you need to ensure that mulberry leaves are healthy and have not been sprayed with pesticides, and mulberry leaves can not occupy rainwater or dew, so as to avoid mulberry silkworm diarrhea death.

4. Inspect the site

When breeding silkworms, it is necessary to inspect a site every night, and pick out the dead silkworms and weak silkworms in time to avoid healthy young silkworms being infected with diseases, and to open the windows every morning to ventilate the silkworm house, because the silkworm breathing volume is larger, and the excrement is more, if the environment is too closed, it will lead to the silkworm infection disease.
