Problems solved by technology
But its nucleolus is small, and the yield of kernel is less than 10%, it is difficult to take out the whole nucleolus, so the utilization rate of wild pecan resources is low now
However, the main reason for the high survival rate of the grafting technique of the present invention is that rootstocks and scion grafts with strong vitality are selected, so it is difficult to popularize; and the patented technology of the present invention is easily disturbed by natural factors, so it is very uncontrollable and difficult To promote the use, so it is difficult to be accepted by the people

Embodiment Construction
[0023] Scion selection: choose a tree with good quality, strong growth, high yield, stable yield, no pests and diseases, and suitable for the production conditions of the breeding place as the mother tree for picking. The branches are strong, well-developed, small-hearted, free of mechanical injury and frostbite, with 1-2 ear buds.
[0024] Collecting scion: Generally, it is selected in February or March every year when the mother tree is in a dormant state.
[0025] Scion collection can be done with hand shears or high-branch shears, and the scissors should be flat. After cutting, seal both ends of the scion with paraffin in time to prevent water loss.
[0026] Wax sealing method: heat up to 95-105°C with 10:2 paraffin wax and beeswax mixture, quickly dip one end of the scion in the wax liquid (within 1 second), and then dip the other end of the scion in the wax liquid Dip it in the middle (within 1 second), so that the surface of the whole scion bar is evenly coated with a...

The invention relates to a Chinese walnut grafting method. Scions are stored in a basket or a carton good in air permeability and placed in a layering mode, the scions are stored in a refrigeration house, and the temperature is controlled between 0 DEG C and 4 DEG C; before grafting of the scion branches, the scion branches are soaked in nutrient solution for 1 minute to 2 minutes, and the temperature of the nutrient solution is kept between 35 DEG C and 40 DEG C. Compared with the prior art, the method has the advantages that the survival rate of grafted Chinese walnut trees is high, the scions are influenced little by outside environment because the scions are stored in the refrigeration house, the scions can be preliminarily processed effectively, and the practicability of the Chinese walnut grafting method is higher; because before grafting of the scions, the scions are soaked in the nutrient solution for 1 minute to 2 minutes, the grafting growth process is accelerated, and the survival rate of the grafted Chinese walnut trees is improved.
Description
Technical field: [0001] The invention relates to a technique for grafting fruit trees, in particular to a technique for cultivating and grafting small walnuts. Background technique: [0002] Wild walnut, that is, hickory is a perennial tree shrub, mainly distributed in mountainous and hilly areas. The growth time is between 50-80 years, the trunk is upright, the crown is relatively short, the root system is developed, and the distribution is deep and wide. It is often mixed with other trees and shrubs, and the spacing between the plants is dense, and the growth ability and adaptability are strong. But its nucleolus is relatively small, and the yield of kernel is less than 10%, and it is difficult to take out the whole nucleolus, so the utilization rate of wild hickory nut resources is low now. [0003] During the grafting process, due to various reasons of the walnut tree variety and the grafting technique itself, there will be low healing ability of rootstock and scion, r...
