Seed treatment is the first line of defense to prevent pests and diseases. To ensure that Miao is full and Miao is strong. The processing method is as follows:
Selection of corn seeds includes ear selection and grain selection. When the ear selection is to dry the ears on the field, the mixed, poorly mature, diseased, and rotted ears are removed and dried for threshing. The grain selection is selected to remove small and glutinous grains before sowing, and to remove mold, broken, insect particles and sundries, so that the size is even and full, which is beneficial to Miaoquan and Miaoqi.
Seed treatment and sun-selection for 2~3 days on sunny days will help to increase the germination rate, early emergence and reduce silk smut.
Soaking seeds can promote the germination of seeds, the emergence of seedlings, and the tidy seedlings. The method is soaking in cold water for 12 to 24 hours; soaking in warm water at 50 ° C for 6 to 12 hours. Soaking seeds should pay attention to the time of full-bodied hard-type seeds, and the time of glutinous and dentate seeds should be short; the seeds soaked should not be sun-dried, not piled up, and should not be packed with plastic bags; When the ground is dry and the sensation is insufficient, do not soak seeds; soaked seeds should be planted in time.
The dressing of the medicament can be used to prevent the corn smut by mixing 15% of the rust-wet WP 400-600 g, and the seedling agent can be used for seed dressing and coating to control the underground pests.

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.).
