Summer and autumn silkworm rearing should be a good "six off"
The silkworms raised during the period from June to October are collectively called summer and autumn silkworms. How can we seize the summer and autumn silkworm yield? We must make a good "six off."
First, disinfection and disease prevention due to continuous sericulture, a large number of pathogens, strong virulence, making silkworms susceptible to disease. Therefore, it must be done after sterilization. Adherence to comprehensive disinfection before silkworm rearing, silkworms often disinfected during the period, silkworm eradication immediately after the end of the period. We must establish a system and implement it consistently.
Second, to improve the quality of leaves In strengthening the management of mulberry, at the same time, we should pay special attention to the mining, transport and storage of mulberry leaves. 1-2 years old should be selected as good mulberry, picking bright green color, touching the upper branches of soft branches, and adopting strong green leaves at the third age. The leaf collection should be based on mining (70% of the leaf volume per day) and should be carried out in the morning when the dew does not dry. The remaining 30% can be picked in the evening. The summer and autumn leaves generally have a low moisture content. After harvesting, they must have special equipment to store them and check them regularly to prevent the mulberry leaves from deteriorating. The leaves of the larvae were first disinfected with bleach containing 0.3% available chlorine 3 hours before the leaves were used.
Third, to improve the environment Around the silkworm room should be planted trees, scaffolding, hanging curtains, to prevent solar radiation heat invade the silkworm room. Small silkworms can cover wet grasshoppers and hang a damp cloth to cool them. It is also possible to set a water tank on the floor of the Jamsil, or use a plastic film to take a temporary water tank and put the well water down. Prevent high temperatures above 860f. At the same time of cooling, we should also be able to relax silkworms, put silkworms in separate stalls, increase the number of feedings to silkworms, feed fresh mulberry leaves, old mulberry leaves, eat wet leaves when wet and dry, and cooperate closely with sericulture technology to reduce High temperature hazards. When it is sultry, it must be ventilated to allow air circulation. If it is cold, it should be warmed.
IV. Careful Feeding During summer and autumn, the temperature is high, and the collar should be carried out at night. During the summer and the autumn period, the length of the night is short, the ant silkworm hatches early, and the ant colony should also be advanced. When the sunrise ants are harvested on the same day, they must receive ants in batches if they do not hatch well to prevent starvation. The temperature is high, and the growth and development of silkworms are fast. It is necessary to appropriately increase the number of times to sang and prevent hungry. In particular, ants should increase 1-2 mulberries on the same day. Due to the large difference in the quality of the leaves during the summer and the autumn, sleep is not easy, and attention must be paid to improving the sleep in batches.
Fifth, the three prevention and control of autumn silkworm to do a good job of flies, ants, anti-virus work.
Sixth, suitable cooked, batch, thin and clear on the close the cluster off, to prevent the occurrence of tussah. Picking can be 1-2 days earlier than the spring season. It is necessary to strengthen observation and pick up at the right time.
