Method for pulling bough in tree shaping and pruning

Abstract

A method for pulling a bough in tree shaping and pruning includes the following steps of bough mechanical damage softening, pulling and angle correction, damage point protection and bough fixing. Themethod specifically includes first selecting the bough of a fruit tree, rip cutting the bough horizontally at the position 10-15 cm from the base of the bough with pruning shears or a hand saw to forma longitudinal crack till the bough is softened; winding a PVC plastic tape or a PVC electrical tape on the cut portion of the bough in time to wrap the cut portion after damage; then turning the front section and the rear section of the bough to pull the bough to 45-90oC and fixing the turned bough with a frame material like a wire. The method prevents the bough from being easily broken during the process of pulling, increases the ventilation and light transmission performance in the canopy, further utilizes the useless bough, facilitates fruit bagging and picking, and improves the yield ofthe fruit tree and the quality of the fruit. The method is simple and practical and has a positive effect on the fruit tree production.

Description

technical field [0001] The invention relates to the technical field of fruit tree shaping and pruning, in particular to a method for treating large branches in fruit tree shaping and pruning. Background technique [0002] Fruit tree pruning is an important technical measure in fruit tree cultivation and management. Fruit tree pruning is mainly to cultivate a solid crown skeleton of fruit trees, adjust the ventilation and light transmission conditions inside the tree, coordinate vegetative growth and reproductive growth, and the aging and renewal of branch groups. , help fruit trees to achieve premature, high yield, stable yield, high quality, longevity and easy management; therefore, the pruning of fruit tree shape has an impact on the difficulty of orchard management, the tree vigor of fruit trees, the prevention and control of diseases and insect pests, and the yield and quality of fruit Extremely large, improper pruning or pruning mistakes, resulting in tree shape not sui...

Problems solved by technology

[0003] In the pruning of fruit trees, branch opening angle is a very important technical measure, especially for large fruit trees such as apple trees and pear trees. Through the opening angle, the orientation of branch buds can be adjusted, the dominance of its top can be controlled, and the growth can be eased, which is beneficial to the tree. The body is ventilated and light-transmitting, flower buds are formed early, and the branches on the backbone branches are evenly distributed in front and back, so as to achieve the purpose of high yield and stable yield; at present, the existing methods for pulling branches of fruit trees mainly use ropes, iron wires, etc. For some small branches, it is easier to operate biennial branches or branches of the same year, and it is not easy to break branches, but as the branches grow and thicken, it is more difficult for perennials and above. The degree of lignification of large branches increases and becomes hardened. At present, the use of ordinary ropes to pull branches is easy to cause breakage and damage, resulting in inappropriate tree structure. Some fruit tree branches cannot be effectively used, and the yield and quality of fruits are reduced. Therefore, a A simple and practical method for dealing with large branches to promote the improvement of fruit tree pruning techniques
