There are two kinds of external fixations for pelvic fractures, namely temporary fixation and therapeutic fixation.
Temporary fixation depends on on-site assistance. Assuming that the patient has serious open injury, severe hemorrhagic shock, and serious fracture dislocation, the rescue personnel will provide temporary external fixation support to maintain the stability of the pelvis, reduce secondary injuries, and correct the continuous aggravation of hemorrhagic loss on the scene. The therapeutic external fixation stent is used to correct the dislocation of the fracture through routine examination after admission, evaluation of the injury, and external fixation installation through treatment, maintain the relative stability of the fracture, create a very quiet environment for the fracture healing, and lay the foundation for the healing of the fracture. External fixation is an important method for pelvic fractures.

Pollution-free Vegetables - Cultivation Techniques of Alpine Eggplant
1 Cultivation Techniques 1.1 Selection of varieties and cultivation plots 1.1.1 Variety: Hangjiang No.1, farmer's chief eggplant, and wild tomato No.1. 1.1.2 Plot selection: In accordance with the requirements of the province's pollution-free vegetable standard (DB33/T291.2-2000), and within 2-3 years, no solanaceous crops and soil pH values ​​of 6.8-7.3 have been planted. 1.2 Nursery 1.2.1 Use amount: 50g/667m2. 1.2.2 Preparation of nutritious soil: formula: 50% vegetable garden soil, 40% mud for composting, 10% for composted manure, 0.1% compound fertilizer, 0.2% superphosphate, evenly mixing, composting for one month in advance Made. 1.3 Sowing 1.3.1 Sowing period: According to the characteristics of high mountain climate, combined with the market demand, the sowing period is generally scheduled to be broadcasted from April 10 to April 15 at the latest by the end of April. 1.3.2 Seed treatment: Soaking seeds in warm water of 50-55°C for 15 minutes, soaking in cold water for 6 hours, washing several times during soaking, washing the seed coat with mucus. Planting began on June 10th and began harvesting on July 10. 1.3.3 Seeding: Prepare the seedbed before sowing and cover 4-5cm thick nutritious soil on the surface of the seedbed and smooth it. Before planting, the footing water should be poured. The soil depth of 8-10cm is required to be wet, and then the seeds are evenly spread. 50g seeds are sown per 4-6m2 seedbed and covered with a layer of 1-1.5cm thick sieved coke after sowing. Finally, it is covered with a thin layer of straw or shade nets for moisturizing and sprouting. 1.3.4 Seedling management: 7-8 days after sowing, when 80% of the seed top soil is uncovered, straw is opened. In the early stage of seedling growth, 1-2 seedlings are to be removed to remove excessive or weak seedlings. After about 30 days of sowing, the seedlings will grow to 2-4 leaves, and the seedlings will be planted 10cm square or 10cm. The nutrition 钵 is planted into 钵. After transplanting, the seedlings are treated with 0.2% urea and 0.3% potassium dihydrogen phosphate as the top dressing. The water is often kept moist to keep the soil moist. 0.5% of urea is used to top-coat the seedlings for 5 days before transplanting, and 75% of them are used. Bacteria clear liquid spray 600-700 times, with medicine transplanted. 1.4 Colonization: The main disease in seedling stage is damping-off disease. Can be controlled with 75% chlorothalonil 500 times or 50% carbendazim 600 times. Insect pests include aphids, thrips, red spiders, and tea aphids. See section 2 for specific methods of prevention and control. 1.4.1 Applying basal fertilizer: Each 667m2 of rotted bar fertilizer 1500kg plus compound fertilizer 20kg. 1.4.2 Soil preparation: Grab a sunny day and do a raft with a width of 1.4m and a depth of 0.2m. 1.4.3 Planting time: The seedling age is about 50 days, 5-6 leaves, and planting in the middle and late May. 1.4.4 Row distance: 35cm spacing, 70cm spacing. 1.4.5 Planting methods: Planting in sunny evenings or cloudy days should be selected, combined with pouring thin human urine to root, in order to facilitate early living rooting. 1.5 Field Management 1.5.1 Dressing: The eggplant has a long growth period and must have sufficient supply of fertilizer and water. The first application of fertilizer is in the eye-opening stage of the eggplant, with 667m2 of 500-1000kg of human excrement, and the concentration is controlled at 30%. When the tomato eggplant is 8-10cm long, apply top dressing 1-2 times, apply 667m2 of thin human excrement 1000-1500kg, or urea 15kg, potassium chloride 15kg, and pour with water. The results can also be carried out during the peak season, top dressing, foliar fertilizer can be used more love, green Fenwei and so on. 1.5.2 Irrigation and Drainage: In high temperature and low rainfall season, irrigation should be taken care of to avoid soil drying. Pay attention to drainage during rainy season. 1.5.3 Plant Adjustment: All the branches below the phylum were removed, and the phytoplasma above the eggplant were not pruned. At the same time, old leaves, diseased leaves and yellow leaves were removed, and some dense leaves were removed depending on the growth conditions to facilitate ventilation and light transmission, increase fruit setting rate, and reduce insect damage. 1.5.4 Preserving flowers and keeping fruits: When the temperature is below 20°C, it is easy to cause falling flowers. Plant growth regulators can be used to preserve and protect fruits. It is usually best when the buds are purple and when the buds are to be put. Commonly Used Hormones List Hormones Variety Use Concentration Method 2,4-D20-25ppm Apply to flower shank and calyx Anti-dropping agent 30-50ppm Apply to flower shank and calyx Place red tomato Ling 1:500 Immersion flower 1:250 Apply to flower handle And pest control 2 pest control 2.1 Chemical control: must meet the provincial pollution-free vegetable standards (DB33/T291.2-2000), strictly control the safety interval. 2.2 Major pests and diseases 2.2.1 The main diseases of eggplant damage are gray mold, brown leaf disease, verticillium wilt, and blight. 2.2.2 The pests that damage the eggplant mainly include red spiders, tea tree aphids, thrips, aphids and leaf miners. 2.3 Control strategies 2.3.1 Based on disease-resistant or disease-resistant varieties, combined with the improvement of plant resistance, agricultural measures are adopted to prevent wilt and verticillium wilt. 2.3.2 For fungal diseases, agricultural control is the main method, and chemical control methods are used in due course. 2.4 Agricultural methods 2.4.1 Cultivated control: The crop rotation is adopted to avoid continuous cropping with the solanaceous vegetables. The deep ditch sorghum is used to prevent water accumulation, clean the pastoral area, apply sufficient basal fertilizer, and increase plant resistance. 2.5 Chemical control 2.5.1 Gray mold can be sprayed with 50% Suo Ke Ling 1500 times liquid, or 50% Doloxivir 1000 times liquid spray. 2.5.2 Brown rot can be sprayed with 75% chlorothalonil 1000 times, or 47% Garnett 800 times spray. 2.5.3 Verticillium wilt 70% DT Wettable powder 600 times Irrigation. 2.5.4 Hummer can be used 20% good winter 2000 times solution, or 10% net 3000 times solution. 2.5.5 Liriomyza can control with 0.2% avermectin 2000 times, or 48% of Losby 1000 times. 2.5.6 Aphid can be used 3000 times 10% imidacloprid, or 50% to avoid fog 3000 times liquid control. 3 Timely harvesting is usually done 25-30 days after flowering, depending on the eggplant eye (white ring-shaped zone where the sepal and fruit are connected). If the eggplant is wide, it means that the fruit grows fast and the eggplant eyes are not obvious, indicating fruit growth. Slower and timely harvesting. Harvesting is best in the morning or evening. The harvest is too early, the fruit is still young, the yield is low, and the harvest is too late, the pulp is rough and affects the later yield. China Agricultural Network Editor
