First, thorough disinfection and disease prevention. Seriously doing a good job of cleaning and disinfecting before and after raising silkworms, which is the key to seize the high output of silkworm cocoons. Once the larvae become ill, they must first isolate the diseased silkworms, correctly diagnose them, and take appropriate measures to prevent and treat them in time. Second, control the meteorological environment. The temperature during summer silkworms often exceeds 30°C, which has a greater impact on silkworms. Large silkworm room should use tall, cool, ventilated houses. It is also possible to spill well water on the surface of the Jamsil floor and walls to reduce the room temperature. When it is hot and humid, fans can be used to make the air in the silkworm room smooth and reduce body temperature. At night, the silkworm room should be opened to lower the room temperature. When dawn, doors and windows should be closed to control the flow of hot air into the room. For the large silkworm period, due to the need for ventilation, the north window should be opened more, and the south window should be less opened. If the south window is opened, wet grass can be hung on the window. Curtain, before and after the silkworm room to take a cool shed and other cooling devices. At the same time, silkworms have more drying materials such as eschar and lime powder, and increase the number of sandfalls. Third, strengthen feeding and management. First, do a good job of "three thin" work, is conducive to cooling ventilation, cannibalism eat. During the high temperature period, the silkworm should be thin, the area of ​​the silkworm should be 10-15% larger than that of the spring silkworm, and the silkworm shelf level should be thinned, which can reduce the temperature of the silkworm nest and facilitate the high yield of the silkworm cocoon. The second is to do a good job recharge Mulberry, especially in the food-rich period, so that the second time to fill the middle of the Sang make up once, so that silkworms satiety, and strong one. The third is timely feeding of wet leaves. Generally small silkworms do not feed wet leaves. When eating wet leaves, it is necessary to spray cool well water in front of mulberry, or pick up dew mulberry leaves as early as possible, which is not only beneficial to mulberry leaves, but also reduces the body temperature of silkworms. Fourth, it is to eat enough to sleep, mention the green batch. Summer silkworm breeding temperature is high, easy to cause lack of mulberry and sleep, therefore, we must pay attention to satiety and sleep, such as missing sleep, must be submitted to the green batch.
