Two autumn silkworm breeding grasp six points
1, thin silkworm head. After the four-year-old leaves are opened, sand removal is performed in time, the seat is expanded, and the silkworm is evenly distributed. The food-rich area is 18-20 square/sheet, silkworm does not touch silkworms, and silkworms have three. In addition, the silkworm seat was expanded and the thin silkworm head was placed in one step. 2, feeding temperature. If the temperature is too low in the early morning or evening, when the temperature is too low, the silkworm will eat sang noodles, the silkworm body will be weak, and it will easily induce silkworm disease. Fourth instar silkworm suitable temperature of 24-25 °C, dry and wet difference of 2-3 °C, silkworm farmers should be based on their own actual situation, according to local conditions, good temperature repair work to ensure the normal development of silkworms progress. When replenishing temperature, pay attention to the safety of humans and silkworms. 3, prevention of silkworm disease. (1) Disinfect the silkworm body. In the fourth and fourth instars, a silkworm anti-stuck powder and fresh lime powder should be used each morning and evening. (2) Add good drugs to food. On the second and fourth days after the fourth-instar opening, an antibiotic such as ciprofloxacin or norafloxacin was added. On the third day, the silkworm flies at a concentration of 400 times, and after spraying and mixing the leaves, it is best. All pharmaceuticals must be used immediately. They are generally used at high temperatures outside the noon. In case of rainy weather, the two agents can be used as a "two in one." 4, ventilation. When the silkworm enters the fourth instar period, the number of sang increases, and the rate of excretion increases due to vigorous breathing. Therefore, ventilation and ventilation must be strengthened to keep the indoor air fresh. 5, mention the green batch. When seeing 80% of silkworms go to sleep, sprinkle fresh lime powder and stop mulberry, go to the top of the net, eliminate weak and late sleep silkworms, the last batch of silkworms, according to the balance principle of leaf silkworm, discard the pawn to protect the car, keep a good silkworm. 6, anti-virus security. Do a good job of feeding mulberry leaves, pay attention to the surrounding environment and prevent accidents.
