Composite grafting method for trees and special device

Abstract

The invention provides a composite grafting method for trees and a special device, belonging to the technical field of tree grafting. According to the invention, an auxiliary grafting technology and a composite grating technology are simultaneously adopted; according to the auxiliary grafting, an auxiliary stock special for supplying nutrition to a main grafted fragment is additionally grafted on the main grafted fragment, the root of the auxiliary stock is cultured in nutrient matrix, and the tip of the auxiliary stock is directly grafted to the main grafted fragment which does not belong to the same main grafted unit as a main root stock; and according to the composite grating, more than two intermediate stocks grafted on one main grafted fragment are grafted to different main grafted fragments, and / or more than two intermediate stocks grafted from different main grafted fragments are grafted to the same main grafted fragment. The special device for tree grafting can realize auxiliary grafting and composite grating. According to the composite grafting method and the special device, multiplicity of multiple grafting and limitation of form are overcome, planar networking grafting and three-dimensional cross grafting of the grafted trees can be realized, and diversification is realized in the tree grafting form.

Description

technical field [0001] The invention relates to tree grafting technology, in particular to a tree compound grafting method and a tree grafting special device. Background technique [0002] The traditional tree grafting method is to directly graft the scion to the rootstock, and the scion completely relies on the grafting surface to absorb nutrients. However, in double grafting and multiple grafting, this grafting method has obvious shortcomings, because the transfer of nutrition requires Through two or more than two grafting joint surfaces, the nutrients that can be absorbed by the scion grafted after the intermediate anvil are greatly limited, resulting in low success rates of double grafting and multiple grafting, and multiple grafting. Multiplicities are severely constrained. [0003] In the multiple grafting of trees, except for the root stock at the first end and the scion at the end, the other intermediate stock is both the rootstock and the scion. Therefore, in this ...

Problems solved by technology

[0005] The invention patent with the patent number "200810303565.1" once disclosed a grafting technique called "multi-rootstock-scion grafting method", which provides a method of grafting multiple rootstocks to another rootstock with roots and On the plant that grows normally as the scion, after the grafting of a plurality of rootstocks and the scion plant is successful, the plant as the scion is cut off from the following grafting position to make it a real scion. The indirect grafting method obtained by improving the grafting method, although it can improve the survival rate of single grafting and double grafting, it cannot be used in multiple, unlimited level grafting of trees

[0006] In the prior art, there is no grafting method and grafting device that can effectively perform multiple grafting of trees and grafting of unlimited levels.
