Nursery 1, nursery bed production. In addition to requiring loose soil and fertility, the nursery bed should avoid redistribution with the same crop, such as onion, onion, garlic, etc., in order to avoid transmission of pests and diseases. Choose a plot and pour 1 pound of water before winter to keep the spring season warm. After spring, fertilization preparation, due to a longer seedling period, the base fertilizer should be sufficient, 5,000 kg per 667 square meters of fertilizing organic fertilizer, deep plowing, the northern area with more broadcast. 2, seed processing. The vitality of leeks seeds must be selected with good new seeds. To germinate in time before sowing, first soaked in warm water at 40°C for 24 hours, remove and germinate at 15-20°C, wash once daily with fresh water, and then expose the whiteheads after 3 days. 3, sowing. After the sorghum flour is evened, sow it evenly and cover 1.5-2 cm of fine soil. Lunan can sow seeds from mid-April to mid-May. Planting leek colonization can be seen seedlings and set. When the seedlings are large, they can be planted before and after the summer solstice, and the seedlings can be planted in September. Generally avoided from July to August, high temperature and rain. In Lunan, many plants are used, and the base fertilizer should be applied to the fields. When planting, cut the top of the seedling root. Leave 2-3 cm, cut one-third of the leaves and reduce transpiration. According to a row spacing of about 15 centimeters, 1 point per 10 centimeters, 10 to 15 strains per hole. Management should be immediately watered after planting. After the new roots are germinated, they will be fertilized and watered. In the summer, the fields should be well drained. White dew to cold dew is the best time to accumulate the growth material of leeks. Field management should be strengthened. Apply urea once every 10 days, each time 10 kg per 667 square meters. The first year of leeks seldom blooms seeds, but management must not be relaxed. Watering once before winter helps maintain moisture and moisture, laying the foundation for early onset of the following year. After the soil thaws in the second year of spring, it enters the management stage. The method is basically the same as that of the previous year. It should be emphasized that the northern cultivation field is sometimes not clearly distinguished from the vegetable field, and attention should be paid to the impact of the number of harvests on the amount of seed production. Mild impacts, but harvesting three pods significantly reduces seed production. Do not harvest before and after harvesting. After entering the flowering stage of the convulsions, watering should be controlled to avoid prolonged lodging, and after flowering, it enters into the filling stage of the seed and chases the compound fertilizer once. Found that some seeds have matured should stop watering. Leek seeds should be harvested separately. In order to prevent bursting, it should be harvested sooner or later, put it in dry and ventilated place, cooked and dried before it can thresh. Amaranth is a perennial rooting plant, so it is not necessary to sow every year. After the third year, the seed production of the harvested field can reach 75 kg.

The DHS system is designed to provide strong and stable internal fixation of a variety of intertrochanteric, subtrochanteric and basilar neck fractures. The plate including stainless steel and titanium model. The DHS plates have a low-profile design, reducing the risk of trochanteric bursits.

The low-profile design reduces the risk of iliotibial band irritation(distal femoral fractures) and trochanteric bursitis(subtrochanteric fractures)

The DCS plates are available with 6 to 16 holes , for varied clinical situations. the DHS/DCS lag screw is available in 50mm to 145mm lengths. The DHS/DCS compression screw can be used for additional compression; only one size compression screw is needed.
