Branch-pulling angle opening device applicable to removal of apical dominance of peach trees

Abstract

The invention discloses a branch-pulling angle opening device applicable to removal of apical dominance of peach trees. The device structurally comprises an apical dominance removal device, an upper fixing ring, an upper branch pulling rod, an accessory branch fixing ring, a lower movable connecting rod, a branch sleeve, a lower fixing ring and fixing hoops, wherein the apical dominance removal device is arranged at the upper end of the upper fixing ring, the lower movable connecting rod is movably connected with the accessory branch fixing ring and the lower fixing ring, the branch sleeve isarranged on the lower fixing ring and adopts an integrated structure with the lower fixing ring, and fixing hoops are assembled on the upper fixing ring, the accessory branch fixing ring and the lowerfixing ring. Bark at the upper ends of the peach trees are girdled by cutters, the apical dominance of the peach trees is removed, suppression of growth of accessory branches is prevented, the branch-pulling angle opening device is beneficial to growth of the accessory branches while the growth angle of a trunk and the accessory branches is properly opened, the accessory branches are thick and robust, and increase of the fruiting rate and the fruiting yield is facilitated.

Description

technical field [0001] The invention relates to the field of fruit tree cultivation, in particular to a branch angle opener suitable for removing the dominance of the top of a peach tree. Background technique [0002] When planting fruit trees, it is necessary to open the growth angle of the main trunk and auxiliary branches of the branches in a timely manner to ensure that the tree posture is opened to enhance the ventilation in the canopy, and at the same time prevent the fruit trees from growing too high and absorbing excess nutrients, which will affect the fruiting of the fruit trees. In order to open the growth angle of the main trunk and the auxiliary branches, a fruit tree branch angle opener needs to be used in fruit tree cultivation. There are the following disadvantages in the prior art branch angle opener: [0003] Peach trees grow faster, and the concentration of auxin produced by the terminal buds is higher. High concentration of auxin inhibits the growth of si...

AI Technical Summary

Problems solved by technology

[0003] Peach trees grow faster, and the concentration of auxin produced by the terminal buds is higher. High concentration of auxin inhibits the growth of side branches, resulting in the peach tree's top advantage being more obvious than other fruit trees. The existing fruit tree branch opening device can only be simple The growth angle between the main trunk of the open branch and the auxiliary branch cannot remove the top dominance of the peach tree, resulting in slow growth of the auxiliary branch, low fruit tree fruiting rate, and reduced yield
