CATDOLL : CATDOLL: Key points of silkworm breeding technology (What are the key points of silkworm breeding technology)

1. 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.

2. 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.

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.

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.
