How to raise silkworms in summer

The summer silkworm period is between the beginning of summer and the beginning of autumn. During this period, the temperature is high, humid and stuffy, and humidity sometimes exceeds the range that can be accommodated by the growth and development of the silkworm. The activity of the enzyme in the silkworm is often hindered, and the metabolic disorder is very likely to cause silkworm disease. Therefore, in the summer of sericulture, we must grasp the following aspects in order to capture the harvest of silkworm cocoons.

First, disinfection and disease prevention

"Sericulture requires high yields and disinfection of the first level." Silkworm diseases are the enemy of the sericulture industry, especially in the spring, where sericulture has occurred, silkworm disease has occurred, and the silkworm silkworm apparatus that has been sterilized has been neglected. The disease is widely distributed, contagious, and disinfection is more important. Therefore, in summer sericulture, it is required that every time a batch of silkworm is reared, 1% bleaching liquid is used, or a mixture of 2% formalin and 0.5% lime is used to disinfect the silkworm silkworm. At the same time, it is necessary to do a good job in environmental sanitation, and silkworm excrement must be regularly cleaned away from the Jamsil concentrated sealing heap. Diseased silkworms and weak silkworms need to be eliminated in time, and they are buried deeply. Strictly implement anti-disease measures such as hand sanitization, shoe replacement, and silkworm use before work.

Second, a reasonable arrangement of sericulture batches

Summer mulberry grows lushly, and the mulberry leaf yield is high. The number and quantity of sericulture must be arranged according to the amount of mulberry leaves. Under normal circumstances, a "water period" is arranged every 15 days or so. It will not only allow sufficient time for the silkworm to sterilize, but also allow the silkworm to eat high-quality mulberry leaves and grow well.

Third, careful management

In order to raise the summer silkworms, we must purchase silkworm eggs suitable for raising under high temperature conditions. On this basis, we will implement large, medium, and small silkworm breeding and small silkworm co-culture. Select mulberry leaves of different ages and collect mulberry twice a day in the early morning and late evening to avoid picking mulberry leaves for feeding silkworms under high temperature and picking worm leaves when they are used for mulberry harvesting, so as to achieve rapid harvesting, loose loading, and express delivery. Keep it fresh. If the temperature is high, the reclaimed mulberry leaves should be moistened and covered with water. The mulberry leaves harvested in rainy days should be promptly spread out and dried. The density of silkworms should be appropriate, to ensure that each silkworm occupies a space of 2-3 heads of silkworm in order to facilitate the silkworm to eat mulberry and activities.

Fourth, a reasonable adjustment of temperature and humidity

The silkworm room should be ventilated and ventilated, prevent stuffiness and moisture, and reduce the damage of the high temperature and humidity of the summer silkworm. When the temperature is high and humid, silkworm sheds or hanged green around the silkworm shed, especially the western arbor can completely block the west wall, and do not let the sun shine directly on the west wall. Open the north and south convection windows so that the air can circulate. Conditional farmers can use electric fans to blow “dashing air” in silkworms.

Beeswax is obtained from the honeycombs of bees after the Honey has been removed by draining or centrifuging. The combs are melted with hot water, steam or solar heat; the melted product is filtered and cast into cakes of yellow beeswax. With detoxification, wound healing, tissue regeneration, pain relieving effect. Commonly used in the ulcer not healing, ecthyma erosion, ulceration of trauma, burn and scald.
