1. Regulating growth pruning method
1. Regulate the strength of growth. In terms of period, to strengthen growth, winter should be heavy in summer, and winter should be cut in advance. On the contrary, winter is lighter than summer, and winter cut is delayed. In terms of measures, to strengthen growth, the branches should be reduced under the premise of making full use of space, weak and strong, flat and straight, fewer fruit branches, elevated buds, and reduced damage. From a local and overall perspective, strengthening local growth should weaken the growth of other parts. For example, controlling the upper can promote the lower, and controlling the strong can promote the weak. In addition, growth regulators can be used, GA for strengthening growth, and B9 and plastic elements for weakening growth.
2. Adjust the angle of branches. Expanding the angle can choose the open branches and buds, which can be pulled, supported, dropped, twisted by external force, and can also use the weight of the fruit branches, leaves, and fruits to fall by themselves. To reduce the angle, the buds on the back are generally selected as cut-out buds, with little or no fruit on the top of the branches; for heads, upright branches are used instead of the original ones.
3. Adjust the density of branches. Increasing the branch tip density can keep the branches as far as possible. You can increase the branches by pinching, cutting, etc.; it can also be shortened to increase the branch tip density. In addition, plastics, cytokinins and other chemical agents can also be used. Measures such as thinning branches and long release can be adopted to reduce the density of branch tips.
2. Adjust the pruning method of flowers and fruits
Increasing the amount of flower buds generally takes a wide angle to accumulate nutrients and promote flower bud differentiation; saplings should be lightly cut, slowly released, twisted, pulled, and applied growth regulators to promote bud differentiation on the basis of ensuring normal growth and appropriate branch and leaf quantity. . To reduce the amount of flower buds, cut is generally heavy, winter is heavy and summer is light. GA etc. are used to strengthen tree vigor, promote the growth of branches and reduce flower bud differentiation.
Measures to preserve flowers and fruits: maintain a reasonable number and proportion of various organs according to the high yield index; improve the light after stopping the shoots to enrich the shoots; select the best to remove the inferior, and retain the strong branches and flower buds.

Rib Locking Plate System is suitable for the fixation of rib fractures,which includes rib locking plate,rib locking screw and rib plate.
Ribs are structures throughout the thoracic cavity that protect vital organs such as the lungs, heart, and liver.The human body has 12 symmetrical pairs of ribs.
Where did the fracture occur?
Rib fractures are more common in adults. Fractures of one or more ribs may occur, and multiple fractures of the same rib may occur. The first to third ribs are shorter, protected by the scapula, clavicle, and upper arm, and are generally less prone to injury, while the floating ribs are more elastic and less prone to fracture. Fractures usually occur in four to seven ribs.
What is the cause of the fracture?
1. Direct violence. Fractures occur where violence directly affects them. They are usually cross-sectional or comminuted. Fracture fragments are often displaced inward and easily penetrate into the lungs, causing pneumothorax and hemothorax.
2. Indirect violence, chest is squeezed back and forth, fractures often occur near the axillary midline. The end of the fracture protruded outwards, which easily punctured the skin and caused open fractures, such as collapse or improper exertion during external cardiac massage. There have also been cases of posterior rib fractures due to violent blows to the anterior chest, or anterior rib fractures due to blows to the posterior chest. Most of the fractures were oblique.
3. Mix violence and others.
What type does fracture have?
1. Simple fracture
2. Incomplete fracture: mostly crack or green branch fracture
3. Complete fracture: most of them are transverse, oblique or comminuted
4. Multiple fractures: one bone and two fractures, multiple rib fractures
5. Open fracture: mostly caused by indirect violence or firearm injury
What are the complications of sternal fracture?
1. Abnormal breathing 2. Pneumothorax 3. Hemothorax
