1. Select cold-resistant, solid storage-resistant, dark green varieties. Before sowing, seed dressing with a new high-fat film (can be mixed with seed coating agents) can avoid underground pests and isolate virus infections without affecting the germination and swelling function, strengthen breathing strength, and improve seed germination rate; choose loose texture, fertile, Seedling cultivation in deep soil layers, strengthen fertilizer and water management at seedling stage, small water diligent irrigation, thin fertilizer diligent application, cultivate strong large seedlings.

2. Apply bio-organic fertilizer before planting and spread evenly. At the same time, quicklime is applied per acre, shallow tillage and fine rake, and the fertilizer, soil, and lime are mixed uniformly, and then the land is prepared.

3. Spray the vegetable Zhuangshenling at the right time to make the stems of the plant stout, the leaves thick, the leaves tender, and the plants flourish. At the same time, it increases the ability to resist disasters, reduces the amount of pesticides and fertilizers, and reduces residual poison.

4. In low-temperature weather, use double or multi-layer film to prevent frost damage. Open the shed film at noon on a sunny day, ventilate and reduce humidity. Before planting the ridge, pour water dung 2 or 3 times. After sealing the ridge, pour the urea solution once.

Pediatric Plate

Pediatric series consists of elastic nail,correction plate,pediatric proximal femoral locking plate,LC-DCP locking plate,reconstruction locking plste,T locking plate.

The special manifestations of pediatric fracture

(1) In children, soft tissue is loose, fascia is elastic, swelling after fracture is early, wide range, and often plaque.

(2) Pay attention to subperiosteal fracture, longitudinal percussion pain and local tenderness to consider the possibility of fracture.

(3) Children can be fever, generally below 38 degrees, caused by hematoma absorption.

(4) Identify the ossification center and epiphyseal plate, and add normal side control if necessary.

Characteristics of pediatric fracture repair

(1) The fracture heals quickly, and the younger the age, the faster the healing.

(2) The healing time of fracture is related to fracture site, fracture type, treatment method and individual situation.

(3) Joint stiffness occurred less.

(4) Have a certain shaping ability, the younger the age, the stronger the shaping ability, but the rotation deformity, the angular deformity inconsistent with the joint activity is more difficult to shape itself.

(5) Metaphyseal and shaft fractures due to hyperemia stimulate epiphyseal plate overgrowth, can cause temporary acceleration of limb growth, femur bone.It can overgrow by 0.8-2cm.

Principles of fracture treatment

The first is reduction, fixation, functional exercise. The principle is no longer to damage the epiphysis and epiphysis plate causing growth and development disorders. Manual reduction, plaster fixation, traction. Closed reduction and internal fixation. Open reduction, internal fixation (elastic needles, Kirschner needles, absorbable nails, absorption rods, various steel plates, external fixation brackets, hollow screws, etc.).
