Novel seedling grafting cultivation method

Abstract

The invention relates to the field of agricultural planting grafting, and provides a novel seedling grafting cultivation method. The sizes of mortise and tenon joints are customized according to the diameter of a rootstock; a fork structure is arranged on the rootstock, and a scion structure complementarily matched with the fork structure is also arranged on the rootstock; the tail end diameter of the scion structure is divided into three equal sections a, b and c; the middle section b is provided with an inserting cone, and the sections a and c at two sides are provided with symmetrical side wings; an angle formed by the side wings and the periphery of a seedling body is beta of 30 degrees; the length of each side wing is L1, and the length of the inserting cone is L2 which is six times the length of L1; the engagement part between the fork structure and the scion structure after engagement is smooth without a gap, is simply tied up by adopting gauze or adhesive tapes, and does not need soil and other nutrient solution. The method provided by the invention is simple in grafting process and large in grafting contact area, changes the conventional methods for cuttage grafting, inarching, adhesive grafting, tooth grafting and the like, and reduces the cultivation cost, the survival rate reaches 100%, and an interface after survival does not have a mark and almost has no difference with the original state by visual measurement.

Description

technical field [0001] The invention relates to the field of agricultural planting grafting, in particular to a seedling grafting method. Background technique [0002] Grafting, one of the methods of artificial vegetative propagation of plants. That is to graft the branches or buds of one plant onto the stem or root of another plant, so that the two parts connected together grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. When grafting, the scion should be closely combined with the cambium of the rootstock to ensure the survival of the scion. The connected branches or buds are called scions, and the grafted plant body is called rootstock or platform wood. Generally select the seedling of tool 2 to 4 buds during scion, become the upper part or the top of plant body after grafting, rootstock becomes the root system part of plant body after grafting. [0003] The main factor affecting the survival of grafting is the affinity be...

Problems solved by technology

Traditional methods such as plugging, docking, bonding, and dental bonding are cumbersome, have a low survival rate, and after survival, the interface is uneven and uneven, which affects the appearance
