Method for moderate trimming wood sided branches in forest

Abstract

The invention is concerned with the middle-degree pruning method for lateral branch, the characteristic is: the woods is the crown closure period or near crown closure when the anaphase young growth and the incipient period half-mature forest, process the middle-degree pruning to the lateral branch (expect the 1 to 2 years top branch, namely pruning of the 1 / 3 to 2 / 3. After three years and the first pruning, the forest enters the crown closure period or near crown closure again, processes the pruning again until the forest enters the anaphase of the half-mature forest. The invention can extend the space between the crowns of the tree, improves the light irradiation state and the light energy utilization ratio.

Description

technical field

[0001] The invention relates to a method for pruning woody plants, in particular to a method for moderately pruning side branches of trees and promoting the growth of trunks. Background technique

[0002] Tree pruning, usually by cutting off part of the branches. The purpose of pruning is to obtain a good tree structure to adjust light, distribute nutrients reasonably, balance tree vigor, and increase yield. Among them, the pruning of fruit trees and economic forests is to increase the output of fruits and other products; the pruning of timber forests is aimed at increasing the output of the trunk part—that is, the volume of timber.

[0003] The intensity of tree pruning is divided into three levels: light pruning - the cut part ≤ 1 / 3 of the branch length; moderate pruning - the cut part accounts for 1 / 3 to 2 / 3 of the branch length; heavy pruning - - The part cut off is ≥ 2 / 3 of the length of the branch.
