First, remove the roots of the twigs or roots that grow from the base of the trunk and wounds that year. Avoid these branches and roots affecting the tree shape and disperse tree nutrients. Pay attention to the following issues during the tree pruning process: The pruning branches must be smooth and cut at an angle of 45 degrees to the clippings. Scissors cut branches, cut off at branches, level with the dry, leaving no residual piles. Thickets of bushes should be level with the ground. Choosing the direction of the trimming buds should be considered from the distribution of the branches within the canopy and the expected strength of the new branches. When the crown needs to be expanded outwards, the clipped buds should remain on the outside of the branches; if you want to fill the void of the internal fistula, the direction of the clipped buds should face inward; for the branches that are growing too vigorously, to suppress the growth of the branches, the weak buds should be used as the clipped buds. When picking weak branches, choose full and strong buds to make clips.
Second, when pruning larger branches and trunks, step-by-step operations can be used. First saw the incision from the underside of the twigs 20 centimeters above the required kerf, with a depth of 1/2 of the thickness of the branches, sawing the branches off from above, leaving a stump, and sawing it from the saw cut In addition to the pile.
Third, sawing off larger branches, resulting in a larger wound surface, often causing it to rot due to rain or bacteria invasion. Therefore, when sawing off the branches of trees, the cut must be smoothed, disinfected with 20% copper sulfate solution, and finally coated with a protective agent (protective wax, tempering paint, etc.), which can play a role in antisepsis and promote wound healing.
Fourth, the pruning period of deciduous and evergreen trees should be different. Deciduous deciduous trees stop growing in winter, when trimming, less nutrient loss and faster wound healing. For evergreen trees, although the winter is a dormant period, cutting branches and leaves is prone to freezing injury. This is due to the fact that the roots and leaves of evergreen trees are active all year round, and their metabolism is more than that. Cutting branches and leaves will cause loss of nutrients, which will affect the growth of trees. Therefore, the pruning period of evergreen trees is generally late spring.
Fifth, pruning tools should be sharp. For the tree machinery and folding ladder, before use, check whether the various components are flexible and loose to prevent accidents. The tree should be tied to the safety rope. When the tree is trimmed on the street, special personnel are required to maintain the site to prevent large branches from falling and hurting passing pedestrians and vehicles.
