Summer sericulture "four notes"

First, pay attention to management

In the summer when mulberry grows vigorously, the number and batch of sericulture should be arranged according to the amount of mulberry leaves. Usually, a "water period" is arranged every 15 days or so, which can make the silkworms eat high-quality mulberry leaves, grow well, and have sufficient time to disinfect the silkworm silkworms.

Second, pay attention to breeding

The selection of summer silkworm species should be purchased in a high-temperature climate, and large, medium and small silkworm compartments and small silkworms should be cultivated. The mulberry leaves are harvested twice a day in the morning and evening. The mulberry leaves should be selected according to the silkworms of different ages. At the same time, the mulberry leaves should be harvested under the hot sun to feed the silkworms. When picking mulberry leaves, remove the insect leaves, diseased yellow leaves, and mud leaves to achieve fast harvesting, loose loading, and fast transportation to maintain freshness. If the mulberry leaves are harvested in rainy days, they should be air-dried in time; when the temperature is high, the mulberry leaves that are harvested should be sprayed with water and covered.

Third, pay attention to disinfection

Silkworm disease is the enemy of the sericulture industry, especially in the spring, raising silkworms several times, and having suffered from silkworm disease and neglecting the disinfected silkworm silkworm. The disease source is widely distributed, the infection is large, and disinfection is more important. Therefore, in summer, sericulture requires that each silkworm should be disinfected with 1% bleaching liquid clarification solution or 2% formalin mixed with 0.5% lime liquid. At the same time, we must do a good job in environmental sanitation. The silkworm manure should be cleaned up and kept away from the Jamsil. Diseased silkworms and weak silkworms should be eliminated in time and concentrated in deep burial. Strictly carry out precautions such as hand washing and disinfection, changing shoes into the room, and dividing silkworms.

Fourth, pay attention to temperature and humidity control

In the summer, the silkworm chamber should be protected from suffocation and moisture, ensure ventilation and ventilation, and reduce the risk of high temperature and humidity in summer silkworms. When the temperature is high and wet, the pergola or the hanging green should be built around the silkworm house. Especially the western pergola should completely block the west wall, and do not let the sun shine directly on the west wall. At the same time, it is necessary to open the south and north convection windows to allow air circulation.
