Problems solved by technology

Although the grafting treatment agent and plant growth regulating liquid adopted in this patent can improve the survival rate of grafting, they have no effect on improving the affinity of scions and rootstocks, and the stability of the plant growth regulating liquid is poor, and the regulating effect is easily affected by environmental changes; Tetrafluoroethylene microporous film is directly wrapped on the grafting site. Although it can improve its air permeability, the temperature inside the film is still high, which will affect the survival rate of the scion.

Embodiment 1

[0021] A method for grafting hickory trees, specifically comprising the following steps:

[0022] (1) Selection and processing of pecan scion: select 1-2 years old branches with strong growth and full bud eyes on a good single plant, collect scions with a length of 10-15cm and a thickness of 1-1.5cm, with 2-4 cm on the scion. A bud, cut off the leaves after harvesting; then put the scion where the xylem is exposed and soak in grafting treatment agent A for 3 hours;

[0023] (2) selection and processing of rootstock: select seedling age as the local wild walnut saplings of 2-3 years as the rootstock, after transplanting and surviving, saw the tip at the smooth place of 1-2 cm in diameter, and the rootstock plane is cut into 3-3. 5 degree slope; one week before grafting, apply a layer of grafting treatment solution B on the slope of the anvil, and cover with a layer of plastic film;

[0024] (3) Grafting: Cut a slit with a depth of 8-10 cm at a position 6-8 cm below the incline...

Abstract

The invention belongs to the field of walnut planting, and particularly relates to a grafting method of Chinese hickory trees. The method specifically comprises the following steps: (1) selecting andtreating Chinese hickory scions; (2) selecting and treating stocks; (3) carrying out grafting; (4) wrapping grafting notches; and (5) carrying out management after grafting. According to the method disclosed by the invention, the scions and the stocks are treated by using a grafting treatment solution, so that the affinity between the scions and the stocks can be improved, and the grafting survival rate is improved; and the grafting notches are wrapped with the grafting treatment agent and a polytetrafluoroethylene microporous film, so that sufficient nutrients can be provided for the growth of the scions, permeability of the polytetrafluoroethylene microporous film is improved, and the scions survive more easily. Through the grafting method of the Chinese hickory trees, the survival rateis high and can reach 93% or above, and later management is simpler.

Description

technical field [0001] The invention belongs to the field of walnut planting, in particular to a method for grafting hickory trees. Background technique [0002] Hickory is a deciduous tree belonging to the family Juglandaceae and the genus Hickory. It is one of the unique economic tree species in my country. Pecan fruit, crispy and crispy, rich in protein, unsaturated fatty acids, vitamin E and other nutrients, has extremely high nutritional value and unique taste and flavor, and is a popular high-grade nut. [0003] The seedlings of hickory trees are mainly grafted and propagated, and the treatment and grafting methods of scions and rootstocks are important factors affecting the seedlings of hickory trees; at present, growth regulators are usually used to process the scions and rootstocks, and the grafting parts are wrapped with film. [0004] The patent application number is 201711210690.3, which discloses a high survival rate hickory grafting method, using humic acid, a...
