Anti-wind-breakage supporting column erecting method for top grafting and head changing of jujube trees

Abstract

The invention relates to an anti-wind-breakage supporting column erecting method for top grafting and head changing of jujube trees. The method comprises the following steps: firstly, selecting a grafting position, grafting a scion, erecting a supporting rod, binding, and finally carrying out post-grafting management, to be specific, vertically binding the selected only one supporting rod on a trunk, binding the base part of a primary branch on the supporting rod in the early growth stage of a developmental branch, when an inward secondary branch grows out of the newly grown developmental branch, binding the secondary branch on the supporting rod; when an outward secondary branch grows out of the newly grown developmental branch, pinching the secondary branch, so as to cut off the main bud at the top end of the developmental branch. The technical method, namely the anti-wind-breakage supporting column erecting method for top grafting and head changing of jujube trees, adopted by the invention has the advantages that the operation is simple, the binding material is saved, the conformity to the growth law of jujube trees is achieved, the rapid forming and precocity fruiting of the jujube trees are facilitated, the wind-breakage effect is ideal and the top grafting and head changing success rate is improved; besides, the defects that the base parts are in shortage of fixed points during the fixing of multiple rods, solid binding is difficult, the growth of jujube trees is influenced, and the top grafting and head changing success rate is low are overcome.

Description

technical field [0001] The invention relates to the field of jujube tree grafting, in particular to a method for high jujube tree grafting, head replacement, windproof folding and standing pillars. Background technique [0002] Jujube tree high grafting is a technology to achieve the purpose of variety improvement by grafting other fine varieties at the base of the trunk or above the trunk of the jujube tree. The high-joint replacement head is convenient and quick for the variety improvement of the existing mature trees, and the effect is good. At present, it has been widely used in jujube trees and other tree species. [0003] However, in the year when jujube trees were high-joint and head-changing, the new jujube heads were particularly easy to be shaken by the wind and broken during the growth process, resulting in the failure of the high-joint head replacement work. In order to avoid wind breakage, the method of multi-pole fixing and vertical pillar fixing is often us...

AI Technical Summary

Problems solved by technology

Practice has proved that the fixed effect of this method is not ideal

The reasons are as follows: 1. Tie the bamboo pole along the direction of the head of the new jujube, and the lack of a fixed point at the base makes it difficult to tie the bamboo pole firmly

2. In the early stage of growth, the tissue of the new jujube head is too tender, and it is easy to damage and affect the growth when it is fixed on the bamboo pole.

Third, with the rapid growth of new jujube heads and the continuous increase in the number of branches and leaves, the slanted bamboo poles lack strong support capacity. In addition, there are more bamboo poles, which invisibly increases the windward area of ​​tall jujube tree heads

Once encountering strong wind, the new jujube head will be broken by the wind together with the bamboo pole, which will lead to the failure of high splicing
