Pay attention to ten points of sericulture in summer and autumn

When it comes to silkworms, we are no stranger. I think many people, like Xiaobian, had the experience of sericulture when they were young, but at that time we were raising silkworms for fun, as a kind of good memories of childhood. But there are many people who rely on sericulture to get rich.

Pay attention to ten points of sericulture in summer and autumn

First, prevent pesticide poisoning. In sericulture season, do not spray insecticidal double and other organochlorine pesticides on the farmland near the silkworm room, its fumigation will lead to silkworm poisoning; silkworm mulberry leaves can be picked and fed to silkworms only after trial feeding.

Mosquito-repellent incense or mosquito or insecticide is prohibited in the silkworm room. In the housing adjacent to the silkworm room, the doors and windows of the silkworm room should also be closed to prevent silkworm poisoning.

Third, the silkworm room should install screen doors and screen windows to prevent flies from entering the silkworm room to harm the silkworm, and add "killing silkworm fly" emulsion or spraying silkworm body to kill maggots.

Fourth, before sericulture, the rat hole should be blocked, the silkworm rack and the wall should be kept at a certain distance, and the feet of the silkworm frame should be sprinkled with lime powder or silkworm medicine to prevent the rats from climbing. To raise silkworms, it is necessary to do a good job of killing rats with drugs.

Fifth, the temperature of sericulture is relatively high in summer and autumn, so it is necessary to open doors and windows and strengthen indoor ventilation. Mulberry leaves are sprayed with fresh water and a breeze is blown by an electric fan, which is also conducive to indoor cooling.

Sixth, diseased silkworms should be cleaned up in time, put into disinfection basins filled with bleach solution or lime slurry, and feed diseased silkworms to livestock and poultry to prevent the spread of pathogens and pollute the environment.

Seventh, silkworm sand contains a large number of pathogens, do not spread around the silkworm room, should be concentrated in the field or put into the dung pit retting system, in order to prevent the spread of pathogens.

Due to the high temperature in summer and autumn and the rapid reproduction of pathogens, attention should be paid to picking leaves as needed, transporting leaves in time and storing leaves reasonably. Mulberry storage ponds should be disinfected once per age, do not feed overnight mulberry leaves.

9. Wet leaves should not be fed in hot and humid weather, mulberry leaves should not be sprinkled with water, sand should be removed frequently, fresh lime powder, dried straw and other materials should be sprinkled to inhibit the growth and reproduction of bacteria.

Ten, is not sericulture season, silkworm room do not store grain, bran and other things, so as to avoid damp mites, sericulture harm to sericulture.

Preparation before sericulture

1. Mulberry planting: silkworms feed on mulberry leaves, so mulberry trees must be planted before sericulture. Please read the article "Mulberry planting Technology Video" about mulberry planting technology. Here the editor will not repeat it.

2, silkworm room: a large silkworm room needs 20 square meters, small silkworm room 10 square meters, special leaf storage room and so on, in order to prevent disease.

3. Silkworm tools: including thermometer, silkworm plaque, plastic film, silkworm net, checkered cluster, silkworm chopsticks, goose feather, mulberry cutting knife, chopping block, mulberry scissors, black cloth and so on. It takes 20 silkworm plaques, 160 square clusters and 14 small silkworm webs to raise a silkworm.

4. Disinfection of silkworm houses and silkworm tools: 7 days before sericulture, clean the silkworm houses and tools, spray and disinfect them with eliminate virus essence or 1% bleach or strong chlorine semen to use half a jin of medicine solution per square meter. Close the doors and windows after spraying and seal for more than 24 hours. At the same time, the environment around the silkworm house should be sprayed and disinfected.

Hatching methods of Silkworm eggs

1. Green: about the eighth day after the silkworm eggs came out of the warehouse, you can see that there is a small black spot at one end of the silkworm eggs, called Dianqing. A piece of silkworm eggs with 20% green eggs will be shaded with black cloth. From the day when the eggs are green, the black cloth will be removed at 5 o'clock in the morning on the third day, and the light will be turned on to hatch.

2. Ant collection: after 3 or 4 hours of photosensitivity, ants can be collected at about 8 ~ 9 o'clock in the morning. The room temperature dropped to 24 ℃, and the temperature increased after the ants were collected. The method of collecting ants is to cut the fresh leaves of the first yellow greening into small cubes of 0.5 cm and sprinkle them on the silkworm plaque with plastic film. The amount of leaves should not be too much, generally about 5 times the amount of ants. Using the slapping method, flatten the silkworm seed paper by hand, take the chopsticks and evenly pat the back of the silkworm seed paper, make the ant silkworm fall off the silkworm plaque, and then scrape the ant silkworm with goose feather and arrange it into a circle or square, which can be fed to the leaves. The silkworm body should be disinfected with a thin layer of "Xiao Bombyx mori Disease Prevention No.1" before the second leaf feeding, and the leaves can not be fed until 10 minutes later.

It can be said that China is a big country of sericulture, and our history of sericulture is relatively long, so our country can also be regarded as a country with rich experience in sericulture, and breeders can exchange and learn good experiences and methods from each other.
