1. 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.

2. 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.

3. How to breed silkworms on a large scale?

Preparation before raising

Silkworm farmers should make the following four preparations before raising silkworms.

1. Report the number of silkworms

New mulberry-planting households can report the number of silkworms when the mulberry trees are about 0.7 meters high. Old households can report the number of silkworms when the first batch of silkworms in spring and autumn is about 0.5 meters high. Other batches report the number of batches when the silkworms are received. One silkworm needs 450 to 500 kilograms of mulberry leaves, and it takes about 25 days from reporting the number of silkworms to receiving the silkworms.

2. Silkworm room

The silkworm room should have a flat and clean floor, with convection windows in front and back, preferably ground-level windows. The doors and windows should be equipped with screens to prevent flies, and the ground-level windows should be equipped with wire mesh to prevent mice. Both greenhouses and cement rooms are acceptable (cement rooms are best in cold weather, and greenhouses are best in hot weather). Raising one silkworm requires about 30 square meters of silkworm rearing area and a 10 square meter dedicated mulberry leaf room.

3. Silkworm tools and medicines

For 1 silkworm bed, you need to prepare the following silkworm tools and medicines: 15 to 20 silkworm winnowing machines with a width of 0.8 meters. Four leaf-picking baskets and about 20 square meters of medicine film. 2 to 3 pairs of slippers, placed in the silkworm room and mulberry leaf room respectively. Several red bricks, mainly for feeding silkworms when raising silkworms on the ground. Generally, 2 rows of bricks are placed in each room to facilitate walking back and forth.

2 special barrels for disinfecting silkworm rooms, 1 sprayer. Do not use barrels and sprayers that have been used to disinfect silkworm rooms. 260 square winnowing sieves. About 60 kg of lime, sprinkle a small amount of water on the silkworms 3 days before the silkworms are taken out.

3. Disinfection

Disinfection is the premise for preventing and controlling silkworm diseases and ensuring high-yield and high-quality silkworm breeding, so it must be done seriously. The first batch of disinfection should be completed within 1 week before the silkworms are received. First, thoroughly clean the silkworm room, mulberry leaf room and surrounding environment, and expose the silkworm tools to the sun, and then disinfect the silkworm room and silkworm tools. The best medicine at present is Xiaoteling.

The preparation method of Xiaoteling is: first crush the main agent, stir it into a paste with a small amount of water, then pour in 25 kg of water, then add the auxiliary agent and stir it slightly. After clarifying for 15 minutes, it can be used. Use a special sprayer to disinfect the silkworm room and all silkworm tools. The disinfection should be comprehensive and thorough. The indoor walls and floors should be sprayed evenly and thoroughly. After spraying, close the doors and windows to keep them moist for 1 hour.

After the disinfectant is completely dry, repeat the above method for disinfection once more. It is better to soak the film, shoes, silkworm tools, etc. in the disinfectant solution for disinfection. After disinfecting the silkworm room twice, open the doors and windows. Note that unsterilized items cannot be placed in the disinfected silkworm room.

Sericulture technology

1. Spray mulberry leaves to feed silkworms

Add 5 ml of fermentation liquid to 1 kg of water, spray 10 kg of mulberry leaves and add food, once a day. Silkworms love to eat, their feces are not smelly, they grow fast, their cocoons are thick and of good quality, and can increase production by about 10%.

2. Spray the silkworm body to cool down and relieve heat

In summer, the temperature is high and silkworms are prone to illness. If the room temperature is too high, silkworms are prone to heatstroke and death. In hot weather, add 5 ml of fermentation liquid to one pound of water and spray it on the silkworm body, once in the afternoon and once every day.

3. Spray mulberry leaves to keep fresh

In summer, the temperature is high, and the collected mulberry leaves will turn yellow and deteriorate if they are piled for a long time. In autumn, the climate is dry, and the collected mulberry leaves will dry and harden if they are kept for a long time. You can add 5 ml of fermentation liquid to one pound of water, use it to spray the mulberry leaves, and then put the mulberry leaves into a woven bag or pile them on the ground, cover them with plastic cloth, and they will still be as green as before after 24 hours.

4. Spray mulberry leaves to promote growth

Add 1-2 ml of fermentation liquid to one pound of water, spray it on the mulberry leaves in the mulberry field, spray 2-3 times a month, and add 0.2% phosphoric acid.

4. New technologies and methods for silkworm breeding?

1. Preparation

Before raising silkworms, be sure to prepare a clean, odor-free cardboard box, and then poke some small holes on the top of the box to facilitate ventilation.

2. Incubation

Place the silkworm eggs in a carton at a temperature of 21-29°C. The incubation time is generally about 11 days.

3. Feeding

(1) When the silkworms are about to hatch, put an appropriate amount of fresh mulberry leaves into the cardboard box for the silkworms to eat.

(2) When silkworms are in the young stage, they can be fed with fresh and tender mulberry leaves. When they are in the adult stage, they can be fed with ordinary mulberry leaves.

(3) Before feeding, be sure to check the mulberry leaves carefully to pick out diseased, moldy, and insect-infested leaves, and make sure there is no water on the leaves, otherwise the silkworms will easily suffer from diarrhea after eating them.

4. Cleaning

(1) The old mulberry leaves in the cartons must be removed regularly and replaced with fresh mulberry leaves. All silkworm feces in the cartons must be cleaned up.

(2) When changing mulberry leaves to clean the feces, you must use a brush. The silkworms on the old mulberry leaves can be gently swept onto the new mulberry leaves, and then the silkworm feces and old mulberry leaves in the cardboard box are cleaned, and finally the new mulberry leaves are put into the cardboard box.

(3) If there are dead silkworms in the carton, be sure to clean it up immediately to prevent other silkworms from being infected.

5. Sericulture technology?

When raising silkworms, you should choose varieties that produce more silk; the temperature in the breeding area should be kept at around 25 degrees, and the air should be kept moist; attention should be paid to disinfection before and during silkworm breeding, and disease prevention should be carried out starting from the 2nd age of silkworms, and maggot prevention should be carried out starting from the 3rd age of silkworms.

Silkworms need to be fed frequently, with small but frequent meals. The amount of feed can be increased appropriately when it is cool at night. From the age of 3, the sand should be removed once a day and the silkworms should be placed on the cocoons at the right time. When the silkworms are old, they should be selected in batches and placed sparsely.

6. How to raise and manage mulberry worms?

1. Introduce high-quality mulberry seedlings and strengthen forest management to achieve efficient utilization. High-quality mulberry seedlings can be promoted in small-scale parks by asexual reproduction, such as through cuttings, grafting, layering and other measures, large-scale transplanting and planting of seedlings can be quickly achieved to achieve efficient mulberry and silkworm breeding. However, if there are too few high-quality mulberry seedlings or the planting scale is too large, sexual reproduction can also be used to achieve fast and efficient mulberry and silkworm breeding by sowing mulberry seeds.

2. Introduce excellent silkworm varieties and manage them scientifically. Selecting excellent silkworm varieties is the key to obtaining high-quality silk. When selecting these varieties, we should combine the actual local conditions to select silkworms that are suitable for the local environment, which is conducive to the growth of silkworms and silk production.

In order to improve the efficiency of young silkworm cultivation, the method of co-cultivation of young silkworms can be adopted. During the cultivation process, a suitable feeding environment and standardized feeding methods should be set up, such as feeding according to the picking standards of leaves suitable for young silkworms. When raising adult silkworms, silkworm platform breeding can be adopted. In order to save manpower, according to the large area and ventilation requirements of adult silkworms, sheds can be built to raise them in the shade of the village. In the process of adult silkworm breeding, nutrition supply and pest control should be strengthened to control the mortality rate of adult silkworms.

7. 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.

8. How to breed 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.
