The benefits of fruit tree winter shears are many. If the fruit tree cut razor is not well protected during the pruning process, the wound healing ability will be poor, the rot disease will be seriously infected, and the tree body will be harmed. In most cases, rot disease occurs most in the kerf, and the kerf should be protected.
1. Try to avoid the absolute low temperature trim. The so-called absolute low temperature period refers to the severe weather of March 9 and 49. Absolute low temperature trimming will cause frostbite in the cut, which will cause nutrient transport to be blocked in the coming year, and it is easy to infect rot disease and deficiency syndrome.
2. When trimming, pay attention to the number and position of the large sawing openings of the whole tree. In particular, there should be no excessively large wounds on the trunk, otherwise it will affect the tree.
3. Try not to leave piles when going to big branches. If the pile is too long, it will rot inward from the slashing part until it spreads to the main part. Some people think that it is better to keep the pile longer and to rot a section to help protect the trunk. This idea is wrong. It is not easy to cause decay without leaving piles. Why do you need to keep piles?
4. The sawing opening should be smooth. There should be no burrs, especially the larger kerfs should be flattened with a sharp knife to facilitate healing.
5. When using scissors to thin the branches, be sure to have a big blade. The crushing of the small blade is easy to attract rot on the remaining branches; when the small blade is on, the crush is on the removed branch, and the cut of the branch is smooth.
6. For fruit trees with rot disease, viral mosaic disease, etc., use different scissors and saws when trimming. The use of saws used on diseased trees and then on the tree can lead to cross-contamination of the disease.
7. After trimming, you must apply a sawing edge for protection. This medication is very important. Applying a closed wound to the wound can prevent the loss of water and avoid the infection of the rot pathogen and promote healing.
8. The wound is protected with clay. The larger wound is made of colloidal soft mud paste, and then wrapped with plastic film to prevent the invasion of pests and diseases, reduce the loss of wound water and facilitate healing.
9. The wound on the trunk or the big branch can also be bridged next spring to connect the upper and lower sides to promote healing.
