What is the purpose of spring silkworm spinning silk?

The purpose of silkworm spinning is to cocoon and protect itself better. Because the pupa in the cocoon is safer and less prone to injury. Spring silkworm is a kind of creature, which is raised in spring. In poetry and literature, silkworm is used to describe teachers and other dedicated people. Silkworms need disinfection, feeding and finally cocoon.

Cleaning work in the feeding process Cleaning, cleaning and disinfection before feeding spring silkworms are the first step to implement prevention-oriented and comprehensive prevention and control, which is an important basis for spring silkworms to win high yield. Especially with the rise and spread of blood-borne suppurative disease of silkworm, it is more important to do a good job of disinfection before rearing silkworm, and it should be done early, quickly, with high quality and good effect. First of all, prepare cleaning tools to clean the dust in the silkworm house, silkworm tools and the surrounding environment. Silkworms are mostly put in leather shoes boxes, and some dead corners inside can't be cleaned. It is recommended to use a cleaning tool at the front end of a brush. The purpose of cleaning is to remove a large number of pathogenic bacteria hidden in ash, kill overwintering pests such as mulberry borers lurking in silkworm houses, and reduce the base and quantity of pathogenic bacteria in silkworm houses. When cleaning, it is required to ensure that there is no obvious dust accumulation around the silkworm house, walls, doors and windows, floors, etc. Silkworm boards, reed curtains and other silkworms have no silk thread and dead silkworms.

Cleaning and disinfection: First, soak the silkworm materials such as the silkworm plaque, the silkworm platform and the reed curtain in river water for 1-2 days, then manually scrub the silkworm materials such as the silkworm plaque, the silkworm platform and the reed curtain, and clean the walls, doors, windows and floors of the silkworm house. The purpose of cleaning is to make the pathogenic bacteria attached to the silkworm house and silkworm utensils fully exposed to the air, so as to improve the effect of drug disinfection. The silkworm room is required to be hexagonal and octagonal, clean, washed with water and not polluting hands; Silkworms have no silk thread, no residual dung, no dead silkworms and no stains. For some silkworm tools that are seriously polluted by diseased silkworms and difficult to clean, soak them in alkaline water to peel off the diseased spots. After cleaning the silkworm, put it in the sun for 5-6 hours.

The disinfection of chemicals can be carried out in two steps. One is wet disinfection with water spray. Spray all sericulture supplies, such as silkworm houses and silkworms, with disinfectant or bleaching powder solution, and keep them moist for 30 minutes. Require accurate dispensing, sufficient dosage, thorough spraying and long moisturizing time. The common concentration of Xiaoshajing is 250 times of aqueous solution, that is, a bag of this product is diluted with 25 kg of water, stirred and dissolved, and then sprayed or soaked for disinfection. Spray disinfection, 225ml per square meter. And ready for use, placed for no more than half a day, without adding alkaline substances such as lime.
