Embodiment 1

[0029] A method for grafting soaked walnuts covered by a mulching film for moisture retention and drainage, comprising the following steps:

[0030] 1) Choose robust, vigorous growth, no pests and diseases, and more than three-year-old Guangxi iron walnuts as rootstocks, and remove the weeds around the rootstocks. Cut the rootstock bast in an oblique ring at a distance of 0.4 meters from the ground to drain the tree body, cut off the rootstock at a distance of 1 meter from the ground, and cut the fracture into a 45-degree slope, flatten the surface to make the slope smooth, and scratch the rootstock cortex Go out two longitudinal slits, described two longitudinal slit lengths are respectively 2cm, 4cm, the transverse distance of described two longitudinal slits is consistent with scion width to be grafted, the bast between two otch is picked apart to form the first For the notch, the same method is used to make the second notch at the relative position of the first notch;

Embodiment 2

[0036] A method for grafting soaked walnuts covered by a mulching film for moisture retention and drainage, comprising the following steps:

[0037] 1) Choose robust, vigorous growth, no pests and diseases, and more than three years old Guangxi native walnuts as rootstocks, and remove the weeds around the rootstocks. At 0.45 meters from the ground, cut the bast of the rootstock in an oblique ring to release water from the tree body, cut off the rootstock at 1.3 meters from the ground, and cut the fracture into a 46-degree slope, flatten the surface to make the slope smooth, and scratch the rootstock cortex Go out two longitudinal otch, described two longitudinal otch lengths are respectively 3cm, 5cm, the lateral distance of described two longitudinal otch is consistent with scion width to be grafted, the bast between two otch is picked apart to form the first For the notch, the same method is used to make the second notch at the relative position of the first notch;

Embodiment 3

[0043] A method for grafting soaked walnuts covered by a mulching film for moisture retention and drainage, comprising the following steps:

[0044]1) Choose robust, vigorous growth, no pests and diseases, and more than three years old Guangxi native walnuts as rootstocks, and remove the weeds around the rootstocks. At 0.5 meters from the ground, cut the bast of the rootstock in an oblique ring to release water from the tree body, cut off the rootstock at 1.5 meters from the ground, and cut the fracture into a 50-degree slope, flatten the surface to make the slope smooth, and scratch the rootstock cortex Go out two vertical slits, described two vertical slit lengths are respectively 4cm, 6cm, the lateral distance of described two vertical slits is consistent with scion width to be grafted, the bast between two otch is picked apart to form the first For the notch, the same method is used to make the second notch at the relative position of the first notch;

Abstract

The invention relates to a fruit tree grafting technology, in particular to a juglans sigillata grafting method. The moisture-preserving and water-draining juglans sigillata grafting method comprises the following steps: cutting off a stock trunk, cutting a fracture into an inclined surface, cutting notches in the bark layer of the stock, and cutting juglans sigillata scions to form steep slope surfaces and gentle slope surfaces; inserting the scions into the notches of the stock for jointing, arranging at least two drainage sticks between the two scions, and enabling the top ends of the drainage sticks to be located between the fracture height of the stock and the top end height of the scions; and binding the joints of the scions and the stock and the drainage sticks with plastic films to expose the top ends of the scions and the drainage sticks, enabling plastic bags to penetrate through top ends of the scions to cover the top ends of the drainage sticks, and sealing the openings of the plastic bags and the top ends of the scions with the plastic films to complete grafting. After grafting, whether water is accumulated on the grafting joints is continuously checked, water drainage measures are taken, grafting work can be completed through one-time operation, water drainage preparation before grafting and subsequent management after grafting are omitted, the method is simple and convenient, and the survival rate of the scions is high.

Description

technical field [0001] The invention relates to a fruit tree grafting technique, in particular to a method for grafting soaked walnuts. Background technique [0002] Bubble walnut (Juglans sigillata Dode) is an important nut and woody oil economic tree species suitable for planting in Southwest China. tonic. [0003] During the planting and grafting of soaked walnuts, due to various reasons of the variety of soaked walnuts and the grafting technology itself, the healing ability of the rootstock and scion may be low, or the wound fluid produced by the section of the rootstock and scion cannot be removed in time, which will make the contact surface of the wound Mildew and rot affect the survival rate of grafting. In addition, the grafting process will also affect the survival rate of grafting due to reasons such as the tightness of the film binding. Therefore it is necessary to improve the prior art. Contents of the invention [0004] The object of the present invention ...
