1. Soil. To grow radishes, you must choose plots with deep soil and good drainage. If there are hard objects such as stones in the soil layer, it will hinder the growth of radish roots, causing the lateral roots of radish to swell and bend, causing the radish to split.

2. Moisture. Radishes need sufficient water during growth, but not too much. If there is a lot of water for two days, it will cause poor soil aeration, inhibit the hypertrophy of the main root of radish, and form many lateral roots. Therefore, drainage work must be done well.

3. Fertilize. Fertilization of radish, especially farmyard manure, must be completely decomposed, and spray Diguozhuangti Ling on the leaves to increase nutrient flow, promote fruit development and expansion, without stimulating cells, non-toxic, and instead of pesticide expansion agents and hormone expansion. The power of radish to absorb water and fertilizer can reduce the occurrence of radish deformities and improve fruit yield and quality.

4. Temperature. Before sowing radishes, you must pay attention to the shed and mulch to keep the appropriate temperature. Spraying new high-fat film on the leaf surface of the field seedlings in the dry season can protect the moisture of the seedlings, improve the plant's drought resistance factor vitality and self-drought resistance.

5. Insect damage. Underground pests will gnaw on radishes and inhibit the growth of the main roots, causing the lateral roots to swell, branching or deformity. Therefore, in the growing period of radish, the use of Root Shitong combined with pesticides to irrigate the roots can promote the effective ingredients of pesticides to kill the root pests of fruit trees.

Trauma Cannulated Screw

Cannulated screw is a common internal fixation device in orthopedic surgery.

Working process

During the operation, the Kirschner wire with the hole matching the hollow screw is first drilled into the bone of the fracture site, and then the hollow screw is screwed into the fracture site through the guidance of the Kirschner wire. Finally, the Kirschner wire is pulled out to complete the fixation of the fracture site. In many cases of fracture of the neck and femur, the healing cycle is long, and it usually takes about 30 months to remove the cannulated screws. At this point, the bone and the surface of the cannulated nail are closely connected and firmly connected in the nail path, which leads to defects easily generated by conventional nail removal methods, causing secondary injury at the fracture healing site and causing pain to the patient. Percutaneous cannulated screw internal fixation for femoral neck fractures has the advantages of small trauma, good healing, low rate of femoral head necrosis, and good stability.
