Embodiment 1

[0022] Masson pine trunk pruning:

[0023] 1. Pruning object: Prune the side buds of 3-year-old Masson pine.

[0024] 2. Pruning time: in early April, when the young leaves are formed and the pine needles have not yet opened (opened).

[0025] 3. Pruning intensity: Evenly remove 2 side buds around the main tip of each trunk.

[0026] 4. Cultivation and management: same as conventional masson pine forest.

[0027] The tree height growth amount of the present embodiment increases 48% compared with contrast.

Embodiment 2

[0029] Pruning of main branches of Huangshan pine:

[0030] 1. Object: Pruning of main branches of Huangshan pine.

[0031] 2. Time: early May.

[0032] 3. Pruning intensity: Cut off one of every three side buds around the main shoot of the plant.

[0033] 4. Cultivation and management: the same as the general Huangshan pine forest.

[0034] The growth of main shoots in this embodiment is 35% higher than that of the control.

Embodiment 3

[0036] Pruning of damaged black pine trunk shoots:

[0037] 1. Objects: Black pine trunk shoots are damaged by pests and other natural disasters, and the growth is hindered.

[0038] 2. Time: mid-April.

[0039] 3. Pruning intensity: cut off the remaining part of the damaged main shoot bud, and choose to keep a side bud branch with the best growth; for other side bud branches, delete (cut) according to the intensity of 1 / 3, and remove all remaining side bud branches tip.

[0040] 4. Cultivation and management: same as conventional forest.

[0041] After the black pine main shoot buds of this embodiment were damaged, the branches were pruned, and the main shoots were replaced by side buds to grow normally, and the height growth was increased by 51% compared with the control.

Abstract

The pine pruning method includes cutting side branches near the main tree top in the site 0.5-1.0 cm from the base part in the last days of March to the first days of May every year from the second year to the 7th-10th year to promote the growth of the main tree top; and substituting one of the side branches for the damaged main tree top. The said method has obvious yield increasing effect, is simple and favorable to tree growth, and may be applied for trees in both timber forest and scenic forest.

Description

field of invention [0001] The invention relates to a method for pruning trees, in particular to a method for pruning trees of the genus Pinus by cutting off side buds and increasing growth. Background technique [0002] There are many species of Pinus L., such as P. massoniana, P. taiwanensis, P. thunbergii and P. bungeana. In the cultivation and management of these tree species, manual pruning is generally required. [0003] Pruning is one of the forest tending measures. In the process of tree growth, the dead branches and some live branches of the trees are trimmed to make the trunk less knotted and the trunk shape round, thereby improving the output and quality of wood. Pinus species are used as timber forests, and the branches are usually pruned after the young forest is closed to promote the growth of the young forest. Generally, from the age of 5 to 7, the lower branches are cut off year by year. Stakes less than 1 cm long. Pruning should make ...
