Pine genus plant grafting method

Abstract

The present invention relates to improved pine grafting technology. In the vigorous growth period after pine fluid flowing, the cold stored scion has the terminal bud bottom cut into wedge, the anvil has the terminal bud cut off and one central cut formed for the scion to be inserted, the cambia of both the anvil and the scion are made to contact closely, and the grafted part is tied and fastened with tying material. The technological scheme of terminal bud wedge grafting is superior to available pine grafting technology, and has high survival rate and high average growth amount.

Description

technical field [0001] The invention relates to a grafting technique for grafting and transforming Pinus plants. Background technique [0002] Existing pinus grafting method mainly contains bud grafting method, split grafting method and pith cambium sticking method etc., and the main content of these methods and the technical defect of existence are: [0003] 1. Budding method: cut off the top bud or the hypertrophic side bud from the mother branch, and cut its base into a symmetrical wedge shape on the cutting surface, cut the same cut as the bud cutting surface on the stem part of the rootstock 5-6cm away from the root, and The incision is at an angle of 30° to the longitudinal direction, and after the cut buds are inserted into the incision, they are tightly wrapped with a plastic film. Although this method has the advantages of less damage to the rootstock and less material used for ear materials, the contact area between the cambium of the scion and the cambium of the ...
