Method for clipping fruit tree heavily

Abstract

A great pruning method for the (8-20)-year aged fruit tree in order to increase the yield of fruit and improve the quality of fruit features that whole fruit tree is greatly pruned in such manner that the upper part of its trunk is removed, only the lower trunk with 80-150 cm in height is retained, the 3-5 primary branches with 30-50 cm in length are only retained, and the new crown skeleton is re-modeled for improving the luminance and air flow.

Description

technical field [0001] The invention relates to a tree pruning method, in particular to a heavy pruning method for promoting young and middle-aged fruit trees to restore tree vigor and sustain high yield. Background technique [0002] The pruning that the present invention refers, is to cut off a part of fruit tree branches, and simultaneously includes the trunk content. [0003] The purpose of tree 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. [0004] 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 len...

Problems solved by technology

But this is only a light pruning, the pruning part is ≤ 1 / 3 of the branch length, and the potential for increasing yield is limited

Moreover, pruning should be started from the young forest period, and the effect will be slow; pruning needs to be carried out every year, and the lack of sunlight in the forest will affect the growth of trees to a certain extent.
