Pruning method of Paulownia

After 5-6 years of Paulownia planting, the tree crown expands. In order to promote its growth, it needs to be trimmed in time. The pruning time is suitable for early spring before germination. The amount of trimming should be reasonable and appropriate, and the cut should be smooth to promote wound healing. Through the shaping and pruning of Paulownia, the pseudo binary branches are transformed into axial branches to form a tall axial trunk or conical crown, which is conducive to timber and good ornamental effect

Shoot cutting and bud wiping

Cutting shoots and wiping buds can cultivate straight Paulownia seedling stems. Generally, cut off the bent and weak tip at the full bud, and remove 4-5 buds below the cut bud. The cut bud can form a new main tip. Pay attention to that the cut bud must be full and strong, and the bud tip faces upward

Sparse branch

Prune over dense branches, Cross branches, weak branches and branches of diseases and insect pests, and do light pruning for weak branches and heavy pruning for strong branches. The cut should be smooth. Thinning branches can weaken the overall growth, but can enhance the growth of the remaining branches, especially the lower branches; At the same time, it is conducive to ventilation and light transmission, and can promote the growth of trunk and early flowering

Short cut

Short cutting is to cut off a part of the branches, which can stimulate the germination of lateral buds under the cutting mouth and emit new shoots, which can increase the number of branches and facilitate more flowering. In a certain range, the heavier the short cut, the more vigorous the sprouting new shoots

Retraction

Retraction is to cut the branches that are 2 years old or more. Keep a section of senescent branches or the base of the trunk, and cut off the rest to promote the vigorous growth of the branches at the lower part of the scissor. It can also stimulate dormant buds to sprout long branches, which is conducive to cultivating new tree crowns

Flat stubble

It is mostly used to cultivate the rejuvenation and renewal of excellent trunk. By removing all the aboveground branches near the ground to stimulate the germination and renewal near the root neck of the plant, the dry shape can be completely transformed< span>
