Shed site conditions and construction. Outdoor scaffolding is the best way to build scaffolding between houses and forests. East-West ventilation is convenient for north-south ventilation, and silkworm excrement is easy to dry, and winter scaffolding is naturally freeze-sterilized after silkworm rearing to reduce the source of disease. There are two types of scaffolding structures, fixed and movable. It is better to use a fixed scaffold. According to the natural terrain and the number of sericulture, the size of the scaffolding is determined, brick columns are used as pillars, and wooden sticks, bamboo rafts, etc. are used as sheds and silkworm scaffolds are used for local materials, and shed roofs are tiled. There are 3 to 4 silkworms in the scaffolds, each about 50 cm apart. Silkworm mats use sun mats, reed mats, bamboo curtains, etc., to form a row or double row silkworm frame, frame width of about 1.5 meters, to facilitate the two relative to feed the leaves and other operations. Each box of silkworm silkworm species needs about 30 square meters. The scaffolding is not walled around, and the rotten fish net can be enclosed to prevent livestock and poultry from entering.
Outdoor scaffolding for raising silkworms should pay attention to the following technical points:
First, small silkworms are kept indoors so that small silkworms develop together. After 4 or 5 instars are fed and fed one leaf, they are bred on silkworm stands. The silkworms on the same layer only put the silkworms that feed on the same batch. Generally, the silkworms that feed on the silkworms are put on the silkworm layer of the lower layer, and the silkworms on the silkworm are put on the upper layer to prevent the silkworm from contaminating the silkworm.
Second, the outdoor scaffolding generally feeds mulberry, and in summer and autumn, if no mulberry must be fed, leaves should be fed with 1 or 2 additional leaves during the day under dry conditions, and be replenished with chloramphenicol or sprayed with clean water. In the silkworm seat, to keep the mulberry leaves fresh, make the silkworm eat.
Third, do not carry out sand removal, but the next day to reduce the underlying stems, reduce the thickness of silkworm sand, silkworms to keep dry, to prevent silkworm mildew steaming fever.
Fourthly, each time the leaves are fed, the area of ​​silkworms is expanded and silkworm heads are kept even.
Fifth, the sericulture scaffolds and the surrounding environment are thoroughly decontaminated with drugs. When sericulture is conducted, the silkworm body is disinfected, and attention is paid to preventing predators such as flies, mice, and birds.
Sixth, after 10% ageing, eucalyptus was used to add food. After 12 to 13 hours, the clusters were placed in clusters.
Custom size medical incision protectors are medical devices specially designed to protect surgical incisions from external contaminants and mechanical damage. They are designed to fit snugly over the incision area and provide a barrier against bacteria, fluids, and other harmful substances that could lead to infection.
To create custom-sized medical incision protectors, medical professionals use advanced 3D scanning and printing technology to create an exact mold of the patient's incision area. This mold is then used to create a custom incision protector that perfectly fits the patient's unique anatomy.
These devices are usually made of medical-grade silicone or other biocompatible materials that are safe for use in the human body. They are easy to apply and remove, and can be reused many times.
Custom sized medical incision protectors are commonly used in a variety of surgical procedures, including orthopedic, cardiac, and plastic surgery. They are an important tool in preventing postoperative infection and ensuring optimal healing outcomes for patients.
