Bark grafting method of apocarya

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...

AI Technical Summary

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 opposite to that of the northern hemisphere

The thin-shelled hickory branches introduced in the southern hemisphere (winter) are grafted in Nanjing (summer), that is, the dormant thin-shelled hickory branches are grafted onto the vigorously growing rootstock, and the survival rate is low by conventional branch grafting or bud grafting.
