But its kernels are small, and the yield of kernels is less than 10%, so it is difficult to take out the whole kernels, so the utilization rate of wild pecan resources is low now

Embodiment Construction

[0017] Scion selection: According to the region and the time of picking and grafting, the main selection is the tree with good quality, robust 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 main varieties selected are Liaohe No. 1, Gongshan vegetative core, Yanyuan early vegetative core, Xinfeng vegetative core and other high-quality perennial vegetative branches or spring parts of trees more than two years old. The branches are strong, well-developed, small-hearted, without mechanical injury or frostbite, with 1-2 ear buds.

[0018] Scion collection: generally choose to carry out when the mother tree for picking the scion is in a dormant state from December to January of the next year.

[0019] 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 ti...

Abstract

The invention discloses a technique for grafting wild Chinese walnut, which comprises: cutting the fracture of a wild walnut or wingnut stock to form an inclined face (1); cutting off 3 to 5 centimeters of skin (2) of the upper end of the higher side of the inclined face (1) to form a 'V' shape (9); cutting off skin (5) in the direction of a bud on a cion branch; peeling the pulp skin layer (3) of the 'V' shape (9) of the stock to separate the pulp skin layer (3) from xylem (4); inserting the inclined plane (6) of a cion from top down while keeping the cion tightly adhering to the xylem (4) of the stock inward; sleeving the whole saw bite on the stock from the joint of the stock and the cion by using an agricultural mulching film; exposing cion branch; and fastening tightly. When the grafting technique is adopted, the operation is simple, the cost is low, and by using wild resources, the grafting survival rate is increased and fruiting is early.

Description

technical field [0001] The invention relates to a technique for grafting fruit trees, in particular to a technique for grafting wild hickory trees with improved varieties. Background technique [0002] Wild hickory is a perennial tree and 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 small, the rate of kernel yield is less than 10%, 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, resulting in low ...
