Abstract

The invention relates to a plant grafting method, and relates to a plant grafting field. According to the invention, branch chips are cut from a scion branch, and rootstock chips are cut from a rootstock graft union; the chips are ground into powder and are well mixed with a nutrient substance; the obtained mixture is spread to the rootstock graft union, and the rootstock grafting surface is tightly wrapped with plastic film; after 7-14 days, the plastic film is removed, and the treated branch is inserted in the rootstock graft union; the grafting position is tightly bundled with agricultural mulches, and is covered with yellow raw mud water. With the method, plant affinity is improved, and a survival rate reaches 100%. The operation is simple, and cost is low.

Description

A kind of plant grafting method

Technical field

The present invention relates to a kind of plant grafting method, belong to plant graft field.

Background technology

Grafting refers to a part of branch or leaf cutting and cut plant corpus, and grafting, on an other strain plant corpus, makes the two become a new plant.Cut and cut branch on plant or bud scion, the plant be grafted is stock.Growth and development of plants after the advantage of grafting can make grafting and yielding positive results, can keep former varietal character constant.Grafting grows fast than cuttage seeding, seedling growth.The ability strengthening maladjustment environment is strong.The resistant to diseases and insects of plant is strong.

The difficulty or ease of grafting survival are from Plant Taxonomy, and the nearer plant graft of affiliation more easily survives, and this is that the difference of organization structure of the plant causes.So-called affinity, be exactly scion and stock in internal organizational structure, in physiology and heredity, mutually the same or close, thus the ability that can be combined with each other.Traditional grafting method is by direct for fringe grafting on stock, and due to the difference of the internal organizational structure of scion and stock, both there are differences, and affinity is not high, particularly there is very large difference between heterologous plant, and survival rate is very low.

Summary of the invention

The technical problem that the present invention mainly solves: poor for affinity during two Plants graftings, cause the problem that survival rate is not high, provide a kind of plant grafting method, the method to be milled mixing by grafting twig, stock and nutriment, be placed in stock grafting mouth, form one and be conducive to stock and the environment of transferring the rapid affinity of lopwood bar, thus improve grafting twig survival rate.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: it is characterized in that concrete steps are:

(1) get a grafting twig, its bottom is whittled into herringbone, long 1 ~ 3cm, be placed in the bottle filling clear water stand-by, described grafting twig is the branch without damage by disease and insect of the age of tree more than 20 years tree crown top peripheral;

(2) annulus is being carved, ring width 1 ~ 3cm, the dark 3 ~ 5mm of ring apart from being cut 1cm branch place, bottom, the branch wood chip reservation that institute carves, for subsequent use;

(3) on stock, cut a grafting mouth, the wide 1 ~ 2cm of interface, dark 3 ~ 7 ㎝, the stock wood chip that cuts retain, for subsequent use, described stock is chosen for without damage by disease and insect;

(4) the above-mentioned branch wood chip carved and the stock wood chip cut respectively are got half, are milled into powder, then mix with nutriment, place stock grafting mouth, and carry out sealed envelope with plastic film, place 7 ~ 14 days,

Described nutriment by its mass ratio be 30 ~ 50 ﹪ kinetins (KT), 15 ~ 20 ﹪ zeatin (ZT), 5 ~ 10 ﹪ 6-benzylaminopurines (6-BA), 15 ~ 25 ﹪ potassium nitrate, 15 ~ 25 ﹪ ammonium sulfate mix;

(5) unclamp plastic film, the branch in clear water bottle is inserted stock grafting mouth, tight with agricultural mulching bondage in grafting place, the more raw muddy water of colored yellow;

(6) observed once every 2 ~ 3 days after grafting, remove the rudiment on stock, and the extermination of disease and insect pest is carried out to it.

The invention has the beneficial effects as follows:

(1) one can be formed and be conducive to grafting twig and the affine environment of stock, thus improve survival rate;

(2) simple to operate, cost is low.
