In the silkworm era, the climate is suitable, the quality of mulberry leaves is good, the pathogen is few, and the disease is low. It is the best silkworm stage in the year. However, to ensure the high yield of spring silkworms, it is still necessary to strengthen the management of silkworms. 1. Completely sterilize the silkworm before. 5 to 7 days before silkworm rearing, the surrounding environment in and outside the silkworm room, silkworm culm, storage mullion room, and upper chamber should be thoroughly cleaned and disinfected. 2. Silkworms carefully disinfected. The silkworm silkworm pedestal is sterilized with silkworm silkworms before the age of the silkworm cocoon for preventing disease 1 or lime anti-stuck powder. In the event of a viral disease, fresh lime powder is sprinkled 1 to 2 times a day; Fresh lime is often sprinkled at the entrance of the silkworm room. Before feeding the leaves and removing the sand, wash your hands and change shoes. Diseased silkworms were found to be eliminated and eliminated to prevent mixed infections. At the same time every 1 to 2 days disinfection with poison Weiwei 1 time. 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 formalin, or fumigated, and then cleaned, cleaned and disinfected. 3. Adjust the climate of Jamsil. 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. 4. Improve ventilation conditions. Open doors and windows regularly to remove 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. 5. timely expansion of sand expansion. The 1st instar does not remove sand, except for the 2nd age and 1st for sleep, and the 3rd instar for the addition, the middle in addition to the insult and the insult for the other. 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. Lime powder is added before the sand removal every day, and 1 to 2 leaves are fed until the net is removed. In addition to sand adjustment silkworm seats. 6. Do it in due course. 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 contrary, too late, there will be "Double Palace", "malformation" and other squat. 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 areas can avoid "diyanomiya," "malformation," "pollution, and paralysis." 7. timely mining, sold out. After 5 to 6 days of silkworm silkworms, they can be picked only when they are brownish brown. It is advisable to select the "Double Palace," "Malform", and "Pollution" squatters and sell them separately.
