The spring climate is suitable. The mulberry leaf has good quality, few pathogens and low pathogenicity. It is the best sericulture period in a year. However, to ensure the high yield of spring silkworms, it is still necessary to strengthen the feeding and management of silkworms.
Thorough disinfection before sericulture
Before 5-7 days of silkworm rearing, it is necessary to thoroughly clean the silkworm room, silkworm worm, storage mullion, and upper chamber inside and out, clean the silkworm room and the surrounding environment before disinfection, and rinse the concrete surface with water. The mud land should be scraped. Go to a layer of topsoil, replace it with new soil, paint the walls with lime slurry, remove weeds and rubbish, clear drains, and remove sewage. Silkworms should be washed with clean water and dried. Disinfection is best done in wet weather or on sunny days sooner or later. Thoroughly sterilize with disinfection king or 1% of available chlorine bleach solution.
Silkworms carefully disinfected
Before each age of silkworm cocoons, use disinfection king or bleach lime anti-stuck powder to disinfect silkworm body and silkworm seat, and add cecroplanet to the second mulberry leaf after 3rd instar foraging, which can prevent bacterial diseases. In the event of viral disease, fresh lime powder is sprayed 1-2 times a day; for silkworm disease, antipersistence powder is sprinkled once a day in the morning and evening. The front door of the silkworm room is often sprinkled with fresh lime. After feeding the mulberry leaves and removing the silkworms, wash your hands and change shoes. Diseased silkworms should be eliminated in time to prevent mixed infections. At the same time, it was sterilized with sulphur fumigation for 1-2 days. The storage and sericulture room grounds are often sterilized with 0.3% available chlorine bleach solution. After the silkworm cocoon is sold, a layer of fresh lime powder is sprinkled on the surface of the silkworm chamber, and the silkworm is sprayed with a disinfection king or a bleaching liquid, and then cleaned, washed or smoked.
Adjusting the environment of the silkworm
The silkworm stage often encounters a low temperature and humidity environment and fails to meet the temperature requirements of silkworms. It can be heated in the silkworm room with charcoal fire, which can play a role in replenishing temperature and eliminating moisture. If the humidity is too low after warming up, boil water to moisturize. Bombyx mori adapts to low-temperature and dry environments, generally the suitable temperature for 4th instar is 24°C-25°C, and the lower temperature below 20°C and the high temperature above 30°C are avoided as far as possible.
Improve ventilation
Open doors and windows regularly to eliminate dirty air and introduce fresh air. At the same time, the silkworm should have a uniform temperature and develop well. The small silkworm room requires weak airflow, and the large silkworm room requires good ventilation and ventilation.
Timely sand removal
1st age does not remove sand, 2 instars, 3 insoles, and 1 in addition to sleep. The large mulberry mulberry had a large amount of mulberry, requiring sand removal, 3 sand removal in the 4th instar, and sand removal in the 5th instar. Every day before the sand removal, lime powder is used to feed 1-2 leaves. When no silkworm is removed under the net, the silkworm is used to adjust the density of the silkworm. The diseased silkworm is isolated and eliminated in time. The dead silkworm should be placed on lime for disinfection. In the tank, they burned or buried deeply.
Do it in a timely manner
Suspending a squatting on the ground prematurely not only made the knot small and thin, but also delayed the entry into the foil camp. The excreted urine could easily contaminate the early knot and increase the “pollutionâ€. On the other hand, if you are too late, you will see "double palaces," "malformations," and other rates. Therefore, when silkworms are cooked at the appropriate time, silkworms can produce silky scabs in time, produce more silk, have superior quality, and produce high amounts of calves. At the same time, the sparsely sparsely populated area can avoid "diyanomiya," "malformation," "pollution," etc.
Timely purchase and sale of cocoons
After 6 to 7 days after the silkworms have grown up, they can pick only when they have a brown color. When picking, it is advisable to select the "Double Palace," "Abnormal Form," "Pollution," and other rates, and sell them separately.
