Problems solved by technology

[0010] The invention solves the problem that the trunk height is more than 150cm, and the tree shape of the trunk branches is upright and not open, which is not suitable for the multi-head high grafting method, and provides a new jujube tree grafting method-the jujube trunk drop-head high grafting method

Embodiment Construction

[0035] The method of connecting the jujube trunk with its head lowered is realized by the following steps:

[0036] 1) Preparation of the scion: intercept the single-bud scion, completely cut off the secondary branch (the section of the secondary branch is flush with the surface of the scion), and cut the section above the bud body (the end close to the bud body is the top) to the back of the bud body. slope, and then wax-sealed to obtain a wax-sealed single-bud scion;

[0037] 2) Choice of pick-up time: from late April to mid-May;

[0038] 3) Implementation of high connection:

[0039]Firstly, handle the scion: cut the back of the wax-sealed single-bud scion from the top to the bottom, so that the back of the bud of the scion forms a smooth slope (also called wedge surface), and then lightly cut the sides of the smooth slope , exposing both sides of the cambium; then cut the section below the bud body of the scion (the end away from the bud body is below) to a length of 0.5...

Abstract

The invention relates to the jujube tree grafting technique, in particular to a jujube tree trunk beheading and top grafting method which aims to solve the problem that the multi-head top grafting method is not applicable to trees with trunk height higher than 150cm and upright but not opening skeleton branch shapes. The jujube tree trunk beheading and top grafting method includes beheading a trunk, burying and inserting a scion into the position below the trunk skin, which is called trunk beheading and top grafting; thoroughly cutting secondary lateral branches from the scion and cutting the section above the bud into a slope facing the back side of the bud; beheading the jujube tree at the position of 120-150cm above the trunk, cutting 3-6 T-shaped grafting openings evenly distributed around the trunk on the bast layer through a grafting knife, and cutting a semi-circular notch on the bast layer on the upper portion of each T-shaped grafting opening, wherein the diameter of each semi-circular notch is the upper cross line of the T-shaped grafting opening. The jujube tree trunk beheading and top grafting method is especially applicable to threes with trunk height higher than 150cm and upright and not opening skeleton branch shapes.

Description

technical field [0001] The invention relates to a jujube tree grafting technique, in particular to a jujube tree trunk drop head high grafting method. Background technique [0002] Jujube high-grafting is a technical measure to achieve variety improvement by grafting other fine varieties on the trunk and above the backbone branches of jujube trees. The technology of high grafting and replacement is the most effective and quickest way to improve the existing mature tree varieties, and it is widely used in jujube and other tree species. [0003] The conventional high-quality replacement technology is to carry out subcutaneous insertion or cleave grafting on the backbone branch, central branch and large fruit branch branched above the main trunk, so it is called "multi-head high grafting". Described multi-head high connection method comprises the following steps: [0004] 1) Preparation of the scion: The scion is a single-bud wax-sealed scion, and the secondary branch of the ...
