The varieties should be selected from No. 4 and No. 7 in the Jinyan series, as well as Beijing squash, Jiamusi thorn and Taiyuan black nest snake.
The seedling raising period is still in the rainy season with high temperature and strong light. It is necessary to choose dry plots for high borders, build a shade above the seedling bed and provide rainproof facilities. After seed dressing, the new high-fat film can be filled with nutrient soil in a paper tube (bag) or a plastic cup to sow and nurse seedlings, so as to protect roots and stabilize roots, and promote seedling growth. The seedlings can be interplanted when the seedlings are cultivated for about 25 days. Each greenhouse is made of three east-west borders, with a row spacing of 1 meter, a border width of 40 cm, and a border height of 16 to 20 cm, and correspondingly leaving three aisles in the south, north and middle. 60 seedlings are planted in each greenhouse. Management enters the stage of vegetative growth (planting until root melon formation), the roof is covered with agricultural film, ventilation is strengthened, and humidity is strictly controlled. When entering the melon formation stage, it is necessary to heat the stove in time to keep the grass curtains covered, make full use of natural light, and prevent melons. Look at the situation of the seedlings and manage the fertilizer and water reasonably. Before the root melon is not harvested, avoid pouring large water to avoid causing root loss and longevity. At this time, squat seedlings are mainly used to control seedlings, to prevent excessive growth of nutrients and delay sitting melon. The time for top dressing should be properly controlled, the seedlings will be mad too early, and the melons will be too late. Generally speaking, when the root melon grows to about 15 centimeters and the waist melon recedes from the flower, it is a good opportunity for top dressing. Fecal water and clean water should be alternated and applied in small amounts and many times. In terms of temperature management, from planting to the squatting stage, the room temperature is preferably 25 ° C during the day and 20 ° C to 22 ° C at night. The growth period of root melon is preferably 24 ℃ to 26 ℃ during the day and 20 ℃ at night. The temperature during the heyday of melon can be appropriately increased, preferably 25 to 27 ℃ during the day and about 22 ℃ at night.

The foot and ankle locking plate is a special-shaped plate specially developed for calcaneal and ankle fractures, which is in line with the anatomical structure of the calcaneal and ankle joints.
During the postoperative treatment process, it can reduce the stimulation of surrounding tissues and promote bone healing.
The calcaneus is the largest of the seven tarsal bones and is located on the lower back of the foot, forming the heel. Calcaneal fractures are relatively rare, accounting for 1% to 2% of all fractures, but are important because they can lead to long-term disability. The most common mechanism of severe calcaneal fractures is axial loading of the foot after a fall from height. Calcaneal fractures can be classified into extra-articular and intra-articular fractures. Extra-articular fractures are generally easier to assess and treat. Patients with calcaneal fractures often have multiple comorbid injuries, and it is important to consider this possibility when evaluating patients.
The ankle joint is composed of the articular surface of the tibia, the lower end of the fibula, and the talar trochlea, so it is also called the talar calf joint. Ankle fractures, including fractures of the medial malleolus, lateral malleolus, posterior malleolus, or fractures of varying degrees occurring simultaneously, are due to greater violence to the medial and lateral malleolus. At the same time of both ankle fractures, the talus directly impinges posteriorly or impinges on the tibia when displaced by external rotation. Fracture of the posterior malleolus due to the posterior margin.
Foot Mini Locking Plate is composed of 2.7mm series of mini locking plate, covering a variety of plate types, widely used in trauma fixation and orthopedic surgery of the forefoot. Anatomical design of bone plate to reduce the need for shaping.
