Winter pruning: The saplings cultivate three main branches and do the branching work. The juvenile tree achieves a uniform result, and the excess flower buds are appropriately removed.
Prevention and control of pests and diseases: Do a good job in clearing the garden and find out that the ring disease is scraped in time.
Peach
1 Continue shaping and trimming, and choose to keep the scion. Remove litter and burn it. 2 Continue to manage the fertilizer, deepen the soil, water conservancy construction, and road maintenance. 3 The new orchard land is level and planted at a fixed point. 4 Do a good job in seedling transportation and indoor seedlings.
Citrus
Antifreeze: In the low temperature period in winter, the antifreeze protection of the tree should be done. 1 dry white: 0.5 kg of quicklime, 3-4 kg of water, 15 g of sulfur powder, a small amount of salt (one tablespoon) to smear the trunk; or dry with fresh cow dung and yellow mud. 2 Rhizosphere soil cover: the soil is thickened in the rhizosphere soil; or covered with straw, straw, weeds, etc.; or covered with a plastic film. 3 Use irrigation before the cold current.
Fertilization: If the winter fertilizer is not applied, it is necessary to grasp the fertilization. Spring fertilizer is generally carried out 1-2 weeks before the spring bud germination. 1 juvenile tree: mainly fast-acting nitrogen fertilizer, the amount of fertilizer increased with the increase of tree age and the expansion of the canopy, generally 3-5 years old saplings, planting 5 kg of human excrement, urea 0.1-0.15 kg, over Calcium phosphate 0.1-0.15 kg. 2 adult trees: promote the application of labor-saving cultivation, after the heavy application of early fertilizer, spring fertilizer can not be applied. According to the conventional fertilization method, spring fertilizer accounts for about 20% of the total fertilization amount in the whole year, mainly based on nitrogen fertilizer and phosphorus and potassium fertilizer. Calculated according to the output of 50 kg / plant, the plant applied 15-20 kg of dilute urine, or 0.2 kg of urea, and 0.5-0.8 kg of ternary compound fertilizer. After the high-rise, the 1-2th single tree and the weak orange tree should be applied quickly.
grape
Plastic pruning: The winter pruning period is better after the fall from the end of December to the beginning of January.
Prevention and control of pests and diseases: Eliminate a variety of wintering scale insects, mites eggs and black pox disease, anthracnose pathogens. After the fallen leaves, combined with winter pruning, cut off various pests and branches, eliminate the residual branches, scrape the old bark, and burn it intensively; spray the trunk, the cement column, and the road around the ground 50 times to 100 times the sodium pentachloro powder.
Kiwi
1 winter plastic trimming, kiwi winter shearing time must start 10 days after the fall, that is, from the mid-November of the solar calendar to the middle of February. 2 soil protection. 3 plants antifreeze, must do a good job in the low temperature period of the tree body antifreeze protection work.

Most endotracheal tubes today are made of polyvinyl chloride, but special tubes made of silicone rubber, latex rubber, or stainless steel are also widely used. Most tubes have an inflatable cuff that seals the trachea and bronchial tree to prevent air leaks and inhalation of stomach contents, blood, secretions and other fluids. Catheters without a capsule may also be used, but their use is mainly limited to pediatric patients (in young children, the cricoid cartilage is the narrowest part of the pediatric airway and usually provides an adequate seal for mechanical ventilation).
Types of endotracheal intubation include oral or nasal, with or without a capsule, prefabricated (e.g., RAE (Ring, Adair, and Elwyn) tubes), reinforced tubes, and double-lumen endobronchial tubes. For human use, tube ID sizes range from 2 to 10.5 mm. Sizes are chosen based on the patient's body size, with smaller sizes used for pediatric and neonatal patients. Tubes larger than 6 mm in diameter usually have inflatable cuff. Originally made of red rubber, most modern tubes are made of polyvinyl chloride. Those placed in the laser field could be flexible metals. Robertshaw (and others) developed a double-lumen endobronchial catheter for thoracic surgery. These allow ventilation from one lung while the other collapses, making surgery easier. After the surgery, the deflated lung is re-inflated to examine the fistula (tears). Another type of endotracheal tube has a small second luminal opening above the inflatable cuff that can be used for aspiration in the nasopharyngeal area and above the cuff to aid in extubation (removal). This allows the aspiration of secretions located above the cuff, which helps reduce the risk of chest infection in patients with prolonged intubation.
