CATDOLL : CATDOLL: Silkworm breeding technology (Silkworm breeding technology and methods)

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. 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.

3. New technology for silkworm breeding?

1. Preparation before silkworm rearing

1. Planting mulberry trees: Silkworms feed on mulberry leaves, so mulberry trees must be planted before raising silkworms.

2. Silkworm room: To raise a bed of silkworms you need a large silkworm room of 20 square meters, a small silkworm room of 10 square meters, and a special leaf storage room to help prevent diseases.

3. Silkworm tools: including thermometer, silkworm plaque, plastic film, silkworm net, checkered cluster, silkworm chopsticks, goose feathers, mulberry cutting knife, chopping board, mulberry scissors, black cloth, etc.

4. Disinfection of silkworm rooms and silkworm tools: 7 days before raising silkworms, clean the silkworm rooms and silkworm tools, and spray them with disinfectant, 1% bleaching powder or strong chlorine solution for disinfection, with half a pound of liquid per square meter. After spraying, close the doors and windows and keep them sealed for more than 24 hours. At the same time, the environment around the silkworm room should be sprayed with disinfectant.

2. Raising silkworms

1. Build a comfortable "home", prepare a box with a lid and poke a small hole, put a layer of clean white paper inside the box, and put the silkworm eggs in the paper box. If the climate is relatively dry, spray a small amount of water every day. As the weather gradually warms up, the silkworms will come out by themselves.

2. During this period, check every day to see if there are any new silkworms. Generally, the most silkworms come out in the morning. As soon as the silkworms come out of the egg shells, they will eat, so you should quickly use a brush or feather to gently brush them onto the mulberry leaves.

3. Larval stage

1. Prepare food. Wash and dry mulberry leaves before feeding them. Do not feed yellow and rotten leaves to silkworms, otherwise the silkworms will be poisoned or have diarrhea. To prevent the excess leaves from wilting quickly, put them in a plastic bag, tie the bag tightly, and place it in a cool place.

2. Feed silkworms with leaves 4 times a day, early in the morning, at noon, in the afternoon, and at night. The amount should be appropriate each time to avoid waste. You can put more leaves at night because silkworms eat mulberry leaves all night long. Silkworms need to be fed with tender leaves, and the leaves are best cut into pieces or strips.

3. Clean up the feces and leftover leaves frequently. When changing leaves for the silkworms, you can directly cover the old leaves with new leaves. When the silkworms have crawled onto the new leaves, take away the old leaves. This can reduce the casualties of the silkworms and facilitate the removal of leftover leaves and silkworm feces.

4. New Technologies

1. Establish and improve the management system

The sericulture industry is a production activity with high technical content. For example, the breeding of high-quality silkworm varieties, unified breeding, unified management, unified inspection and quarantine, mid-term management of silkworms, late-term harvesting, and entering the market all require a complete management system to better improve production efficiency and competitiveness.

2. Scientific and standardized management

The development of the sericulture industry is inseparable from scientific management and technology. On the one hand, the selection and cultivation of mulberry seedlings and the management of mulberry gardens must be strictly carried out according to standards; on the other hand, strict management and application of scientific technology are also required in the breeding process.

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. 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.
