Problems solved by technology

The grafting method of above-mentioned prior art can't derive because of the "injury flow" that grafting interface forms, therefore, often cause the survival rate of walnut skinning grafting to be very low, generally only about 10%; And because the difference on geography and climate, The climate of the southern hemisphere is opp

Embodiment 1

[0032]In August, cross-cut the thriving 2-3-year-old thin-shell hickory rootstock to the xylem, and cut obliquely above the incision to form a '∠'-shaped incision, that is, a 45-degree incision. Edges cut down. The length is 3cm, and the width depends on the thickness of the scion, and the thriving rootstock or lignified branch is cut across to half of the diameter from the xylem to the branch;

[0033] Spike treatment

[0034] Both sides of the dormant branches are cut with a knife to form a double-sided wedge, and the plant growth regulator is soaked. The plant growth regulator is: 3 parts of α-naphthalene acetic acid, 2 parts of indole butyric acid, 1 part of gibberellin, vitamin B1 is 0.5 parts, soak the lower part of the branches for 10 minutes at a dilution ratio of 200mg: 1L;

[0035] Put paraffin wax and rosin into the pot according to the mass ratio of 2:1, control the temperature at 100-120°C, quickly dip in the wax for 1-2 seconds, so as not to scald the scion, th...

Abstract

The invention relates to 'a bark grafting method of apocarya' and belongs to the field of fruit trees and forest tree breeding. The method includes cutting a stock or a lignification branch of the apocarya in vigorous growth to the xylem, conducing inclining cutting on the portion above a cut to form a 45-degree cut, cutting downwards on an edge bark layer of the cut through a stem grafting knife for 3cm with cutting length as 3cm and cutting width determined by scion thickness and conducting scion branch processing and grafting. By means of the method, summer grafting survival rate of scions dormant in winter is greatly improved, the problem of scion grafting survival of ligneous plants like the apocarya which is introduced from the southern hemisphere in summer is effectively removed, and simultaneously grafting period of the apocarya can be prolonged.

Description

technical field [0001] The invention belongs to the field of fruit tree and forest tree breeding, and in particular relates to a method for grafting hickory with thin shell. Background technique [0002] Thin-shelled hickory, also known as American hickory, is a species of Juglandaceae and Hickory. Native to the United States and Mexico, it is one of the most important oil-bearing dried fruit tree species in the world. Its shell is thin and easy to peel, its kernels are thick and fleshy, and it has a delicious taste and high nutritional value. The trunk is straight, the tree shape is beautiful, the roots are deep and the leaves are luxuriant, and it is an excellent tree species for greening and gardening around. At the same time, the wood is tough and dense, with dark red heartwood, yellow-white sapwood, high elasticity, and is not easy to deform and crack. It is an excellent timber tree species for construction and high-end furniture. Therefore, pecan is an excellent econ...
