The direction of bud cutting should be considered from the distribution of branches in the crown and the expected growth of new branches. When the crown needs to expand outward, cut buds should be left outside the branches.
2. When pruning larger branches and trunks, step-by-step operation can be adopted.
First, cut the kerf upward from the lower part of the branch at a position 20 cm above the required kerf, the depth is half of the thickness of the branch, and cut off the branch from the upper part, leaving a residual pile, and then saw off the residual pile from the kerf to prevent the wall of the branch from cracking.
3. When the larger branches are sawed off, the wound surface is larger and often rots due to rain or bacterial invasion.
Therefore, when sawing off the branches of trees, the kerf must be smooth, disinfected with 20% copper sulfate solution, and finally coated with a layer of happy forest plant wound healing agent. It can prevent corrosion and dryness and promote healing.
4. The pruning period of deciduous trees and evergreen trees should be different.
In winter, deciduous trees stop growing and then prune, resulting in less nutrient loss and faster wound healing. Although evergreen trees are dormant in winter, cutting off branches and leaves is in danger of freezing injury.
Because the roots and branches of evergreen trees are active all year round, the metabolism has not stopped, so the nutrients in the leaves are not completely used for storage. Cut off branches and leaves, lose nutrients and affect the growth of trees. Evergreen trees are usually pruned in late spring after winter.
5. When pruning, tools should be kept sharp, and trees should be placed on machinery and ladders. Before use, check whether all components are flexible and loose to prevent accidents.
Fasten the safety rope when climbing the tree. When working near high-voltage lines, pay special attention to safety to avoid electric shock, and ask the power supply department to cooperate if necessary. When pruning roadside trees, special personnel will be arranged to maintain the site to prevent sawing off large branches and injuring passers-by and vehicles.

Tree shaping and pruning program
One knowledge, two views, three cuts, four investigations and five treatments:
1, to understand the operation procedures, technical specifications and special requirements of plastic trimming;
2. Before pruning, carefully observe the surroundings of the tree, make clear the functions and pruning measures;
3. Prune according to the principle of local conditions and branch pruning. The pruning order is "from base to top, from inside to outside". Firstly, the shape of the trimmed crown is determined, and then it is gradually trimmed from the base of the main branch from the inside out;
4. After pruning, check whether there is any missing or wrong shearing, and whether to make up the shearing;
5. Repair and smear large-area wounds, clean up and collect chips, etc.
