In the development and production of fruit trees, it is crucial to understand and scientifically manage the environmental conditions influenced by surrounding "ecological forests." If planting is done without considering these factors, fruit trees may spread through the "sources of surrounding forests," leading to an increased risk of pests and diseases. Therefore, when planning economic fruit tree cultivation, it's important to avoid planting certain species that act as carriers of harmful pests and pathogens.
Artichokes, also known as hedgehogs, grow quickly and have high-quality wood. However, they should not be planted near orchards. This is because artichokes are prone to attract pests like cockroaches, which can damage fruit trees. Grasshoppers are common pests in forest fruit and crop production, causing leaf discoloration, drying, and even death. They can also lead to fruit deformation, reducing both the quality and market value of the harvest. Additionally, artichokes serve as overwintering hosts for anthracnose fungi affecting Rosaceae plants such as apple and pear trees. Planting them near these trees increases the risk of disease spread.
Pine pollen can harm pear trees located up to two or three hundred meters away, causing leaf spots, curling, and even fruit deformity. This reduces the yield and affects the overall quality of pears. To prevent this, pear orchards should be established at least 500 meters away from pine forests.
Paulownia, a fast-growing economic tree, is a primary host for the purple stripe pathogen that affects fruit tree roots. Planting Paulownia within orchards can promote the spread of this disease, which impacts seedlings, young trees, and mature fruit trees alike. Affected trees may show stunted growth, yellowing leaves, and premature leaf drop. In severe cases, the disease causes branch dieback and can eventually kill the entire tree, leading to significant losses.
Cypress trees, including species like Sabina chinensis, Platycladus orientalis, and others, are often associated with pear rust, a fungal disease. The fungus infects pear trees and then moves to cypress trees during winter, continuing its life cycle and re-infecting pears the following season. This is why there is a saying in forestry: "Pear and cypress are enemies, and must not be planted together."
Eucalyptus, another widely cultivated economic tree, releases certain organic compounds through its roots that are highly toxic to grapevines. Grapes are extremely sensitive to these substances, and exposure can cause root rot and eventual plant death. Studies indicate that even a few meters of distance between eucalyptus and grapevines can significantly reduce the negative impact. Therefore, careful planning is essential to avoid cross-contamination and ensure healthy fruit production.
Rib Plate
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
