How to apply bio-organic fertilizer to grapes
There are more nitrogen fertilizers in the early stage of the grape, and more phosphorus and potassium fertilizers are needed in the later stage. Grapes should be fully fermented with organic fertilizers. Chemical fertilizers should be added to organic fertilizers (sodium nitrate, urea, potassium nitrate, superphosphate, etc.). Base fertilizer: After harvesting the fruit until the new shoots are fully mature, at the end of September and early October get on. The base fertilizer is mainly bio-organic fertilizer, and the application of bio-organic fertilizer is 350-450 kg per mu, and 50 kg of super-calcium phosphate is mixed. It is applied along the vine row on one side, and top dressing: generally applied 10 days before flowering, strain Apply bio-organic fertilizer 3 to 5 kg, with 100 g of urea, ditch or acupoint application. The second top dressing in early July, the plant applied bio-organic fertilizer 2 ~ 3 kg, with the application of potassium sulfate 100 grams.

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.).
