How to prune poplars?

Pruning should be carried out near the trunk, and the cutting mouth should be smooth, and no stubble or bark can be left. The incision can heal in the same year; There are often tendons sprouting at the plastic trimming and sawing, which should be erased in time in late spring and early summer.

When pruning, twigs are generally shaved with a quick axe or machete from bottom to top close to the trunk to keep the incision smooth and tidy, which is conducive to wound healing; For thicker branches, it is advisable to use a saw, first from bottom to top, and then from top to bottom, to avoid tearing the bark and causing rough cuts and cracks.

Extended data 1, shaping. After the first year, pruning the side branches competing with the main branches and a few lower side branches; Prune rough competitive branches in the second and third years, and prune a few lower side branches.

After that, pruning is repeated every four years until a smooth young poplar forest with 6 meters of dry wood is formed. Before the garden is closed, the light conditions in the forest are still good, so we should trim less or not, try to keep the big crown and increase the photosynthetic area, but the competitive branches must be thinned out. When there are competing branches (double-headed phenomenon), only one branch is selected; If the main branch is dead and broken, do you want the main branch to erect a side branch to extend and grow and cultivate into a new central main branch?

2. plums. Trim the side branches at the lower part of the trunk in time and gradually improve the branch points. 1-3 years, with a small amount of pruning. 4-5 years, pruning to the height of 1/3. After 6 years, the tree was pruned to the height of 1/2- 1/3 until it was 6 meters. For some trees whose trunks are very short, but the trees have grown up and can no longer be cultivated as solitary trees, you can also cultivate meristems as trunks and increase branches year by year, which is called multi-stem. ?

After enclosure, the trunk thickness of poplar is 8 ~ 10 cm, except for the dying branches in the lower part of the crown, the crown keeps 2/3 of the dry height, and only the extra thick branches and neck branches are pruned in the upper part. Trim the thick branches twice to avoid the wound being too big.
