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 feeding and management of silkworms.
Before silkworm is completely disinfected and sericultured for 5-7 days, thoroughly clean the environment inside and outside of the silkworm, silkworm culm, storage mullion, and upper chamber, and thoroughly sterilize it with a disinfection king or 1% available chlorine bleach clarifier. .
The silkworm stage carefully sterilizes each age from silkworm cocoons and uses disinfection king or bleaching powder lime anti-stuck powder to disinfect silkworm body silkworms. After the third instar feeding, the second time of mulberry is added to eat the chrysanthemum stars to prevent and treat bacterial diseases. In the event of viral disease, sprinkle fresh lime powder 1-2 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 should be eliminated in time to prevent mixed infections. At the same time, it was sterilized with sulphur fume every 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 climate of silkworm room The spring silkworm season often encounters a low temperature and humidity environment and fails to meet the temperature requirement of silkworms. It can be heated in charcoal fire in the silkworm room and can play the role of replenishing temperature and eliminating moisture. If the humidity is too low after warming up, boil water to moisturize.
To improve ventilation, open doors and windows regularly, 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.
Timely sand removal and expansion of 1st age do not remove sand, 2 instars, 3 insults and sleep in addition to 1 time. 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, lime powder is sprinkled and 1-2 leaves are fed until the net is removed. Combined with sand removal adjustment silkworms dense.
Doing timely arrests and premature arrest of mulberry, not only small and thin, but also late in the foil-fencing camp, the excreted urine can easily be contaminated as early as possible, thereby increasing the "pollution". 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 area can avoid "diyanomiya", "deformation", "pollution", etc. The silkworm cocoon was picked and sold 6-7 days after the upper cocoon was harvested. When the cocoon was brown, it could be picked. It is advisable to select the "Double Palace," "Malform", and "Pollution" squatters and sell them separately.
