First, the emerald jade bitter melon variety Very early-maturing and high-yield bitter gourd variety, the plant grows prosperously, the branching ability is strong, the melon strip is cylindrical, straight and beautiful, the melon strip is green, the melon surface is short between the knobs, the tumor is thicker than the flat, the melon length is 28-32 Centimeter, 7-9 cm in diameter, 400-600 g in single melon. The meat is crisp and tender, and it is cool and bitter. It has good heat resistance and strong disease resistance, and is suitable for planting in high temperature and rainy areas of the Yangtze River Basin. The spring sowing is about 75 days from sowing to the beginning, and the whole growth period is 240-260 days. Under the condition of good management, the output per mu is about 4,500 kg. Second, germination The bitter gourd is native to the tropics, and the seed germination needs to be warmer. Most varieties require more than 25 degrees to promote germination. The following two methods of germination are introduced: one is the soaking method to germination, the first step is to soak the 35 degree heat soaking in just 1-2 hours. The second step is washed with water, air-dried surface moisture, wrapped in dry gauze, outsourced in plastic bags, placed in 25-28 degrees germination, re-washed with warm water every other day, then air dried surface moisture, wrapped in gauze. The third step has been to smear out the buds, and the black mold hyphae are washed with warm water to continue germination. The germination can be used with an incubator, an electric blanket, a small amount can be carried with you, sleep with people at night, and use the body temperature to germination. The second is dry seed germination, direct germination without soaking seeds, seedlings stronger than soaking seeds and germination. More cold-tolerant, anti-seedling disease. The first step is to use a culture vessel or a shallow flat plate to lay 5-8 layers of the tissue paper, put a layer of bitter gourd seeds, and put warm water on the tissue paper until the paper is soaked and not dripping, the moisture is too low, the germination rate is low, the second Step on wet gauze or other cotton cloth, coat plastic film bag placed at 25-28 degrees to germination, check once a day, the third step with soaking seed germination method Third, land selection, land preparation The root system of bitter gourd is more developed. It is necessary to choose a bitter melon with a deep soil layer. The deeper the soil layer, the longer the bitter melon grows. The soil is best in loam, followed by clay and sand. Bitter melons should not be used for continuous cropping. They should choose land that has not been planted in bitter melon in recent years or use grafting cultivation, and do a good job of winter ploughing and drying soil. The bitter gourd has a long growing period, high yield, and large amount of fertilizer. Therefore, in combination with land preparation, the base fertilizer should be applied. Generally, 667m2 should be applied with high-quality decomposed farmyard manure 4000-5000kg and ternary compound fertilizer 50kg. The application of the base fertilizer should be carried out by combining the general application of the ground and the centralized fertilization of the ditch. Generally 2/3 of the fertilizer is used as a general application, and 1/3 is used as a ditch or a hole. Pu Shiji fertilizer is ploughed and turned into a compartment. Generally, it is cultivated in a single row and inserted in a straight row (bamboo frame). The straight row height is 2.5-3m; the cabin width is 2.8-3m (including the ditch), wherein the cabin width is 2.6m, and the cabin height is 20-. 30cm, 2 rows per box. If the flat frame is used for cultivation, the width of the cabin is 3-4m (including the ditch), and each row is 2 rows. Fourth, planting and planting It can be sown in spring, summer, autumn and autumn in the south. It should be warmed by the geothermal line before the spring, and the sunshade net is used for sowing in summer. The 110-day countdown from the first frost period is the latest sowing period of autumn sowing. The final sowing period can be determined according to local climatic conditions. The northern open field is planted in spring and summer, and the south of Beijing can be planted on June 20 at the latest. Generally, single row planting is adopted, and the plant spacing is 1--1.5m (320--480 plants per acre); if grafting is used, the plant spacing is 2--3m (160--240 plants per acre). The planting distance of the flat planting plants is 1.5--2m (240--320 plants per acre); the grafting planting distance is 2-2.5m (190--240 plants per acre). V. Mid-term management After colonization, the seedlings are cultivated to promote root development. After cultivating, the soil layer can be loosened, the ground temperature can be raised, the root system can be promoted, and the weed growth can be controlled. After field scaffolding, no more cultivating, but care should be taken to remove the weeds in the field. When the bitter gourd seedlings start to climb vines at a height of 40cm, they should be framed in time, and the vines should be put on shelves, and the type of vines, or spiral-shaped vines. The bitter gourd has a weaker climbing ability, and it still needs to be tied when the vine is put on the shelf. Generally, the vine length is 40cm and tied for the first time. After that, it is tied every 4-6 knots. The tied vines should be carried out after 9:00 am to prevent the vines from breaking. Combined with vines, it can be pruned. In the middle and late stages of development, the aging yellow leaves and some dense side vines in the lower part of the plant should be removed to facilitate ventilation and light transmission, and reduce pests and diseases. 6. Pest control and harvesting Bitter melon is mainly based on picking melon, and it is generally suitable for harvesting 12-15 days after flowering. If the harvest is too early, the bitterness is strong and the yield is low; if the harvest is too late, the fruit is ripe and turn yellow, the meat is soft, and it is not resistant to storage and transportation. The results should be diligent in the prime period, usually picked once every 2-3 days. The main diseases of this variety are: downy mildew, powdery mildew, gray mold and so on. The main pests are: small tigers, cockroaches, melon flies, melons, melons, etc., should use the corresponding low-toxic and low-residue pesticides. Although bitter taste is bitter, its unique taste is still loved by people. Therefore, bitter gourd has certain planting value as a common vegetable.

The wrist joint external fixation fully considers the physiological characteristics of the wrist joint and the structural stability of the biomechanics, so that the metacarpophalangeal joint can be completely bent freely, and the tendons and ligaments of the fingers and wrists can be relatively relaxed. Moreover, the insertion method, length and stress of the bone traction needle are also considered, and the overall force of the bone traction needle is relatively uniform.
The ulna radius external fixator fractures is relatively simple, generally unilateral fixation, or simple combination fixation, generally should not fix the upper and lower radioulnar joints. Radial external fixation stenting has a good effect on the treatment of fracture. Premature removal after surgery is not appropriate, which is easy to cause dislocation and affect fracture healing. Functional exercise can be carried out gradually after four weeks of plaster external fixation, when the wrist joint function should gradually return to normal.
