Chinese chestnut branch embedding grafting method

Abstract

Provided is a Chinese chestnut branch embedding grafting method. When stock or young trees reach the grafting standard, grafting is performed, and the grafting method includes the steps of scion grafting, two-incision grafting, management performed on the current grafting year and pruning of live tree columns. Because the cortical layers of seedlings of nursery land and the cortical layers of the young trees which are planted newly are thin, the branch embedding grafting method can effectively protect the critical layers of branches and trunks, and the method is simple, practical and high in survival rate. Through the method, coppice shoots, generated after grafting, of the branches and the trunks can be removed in time or bud picking is performed as soon as possible, loss of tree liquid nutrient is reduced, and grafted buds can grow healthily and strongly. The method is particularly suitable for cultivating grafting seedlings in the nursery land and being used in a Chinese chestnut orchard where the young trees are newly planted, and the method can also be used for grafting of the branches and the trunks, with thin critical layers, of adult Chinese chestnut trees and grafting seedling cultivation of other fruit trees.

Description

Technical field [0001] The invention involves the grafting method of fruit trees, especially the chestnuts of chestnuts. Background technique [0002] The grafting of chestnut trees is sophisticated with other fruit trees: ⑴ The branches of chestnuts are in the growing season, and the sap composition contains tannins. This substance encounters the oxygen in the air, which will cause chemical reactions to form a composite septum.The layer is dark brown, which directly affects grafting and even cannot survive.树 Adult trees and old bark are thick, which is easy to form wrinkles and peeling. The dermis layer of young branches is extremely thin, which can easily cause damage and form dark brown spot.(3) The base of the chestnut branches has a long life and many lurks and many. When encountering mechanical stimuli, it is easy to germinate a lot of long branches.The scion used by the chestnut grafting is not well preserved, it is easy to lose water, and the grafting rate is reduced.

Problems solved by technology

⑷ The scion used for chestnut grafting is not well preserved, easy to lose water, and the survival rate of grafting is reduced

The interface of these two grafting methods heals slowly and the survival rate is low

[0004] Chinese patent CN100409738 discloses a "grafting method for chestnut trees", which is adapted to the "happy, branch-pulling, early bud bud technology", and has the advantages of avoiding the loss of grafted trees during the bleeding period and avoiding the occurrence of strong wind damage to the branches. Its shortcomings are: it is suitable for grafting large trees, the survival rate is low, and the grafting steps are more complicated
