Abstract

The invention relates to a method for grafting plants, and belongs to the field of plant grafting. According to the method, through pretreating grafted branches, and culturing grafted branches containing stock genes under assistance of nutritional substances, the affinity of stock to grafted branches is improved, and the survival rate is improved. By the method, the grafted branches containing stock genes are cultured, so that the affinity of the stock and grafted branches can be improved, and the survival rate can be improved. The method has the advantages of simple operation and low cost.

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

Wherein a kind of propagation method that grafting uses in gardening for plant, the breeding meaning some not being produced to seed bearing fruit tree (as persimmon, some kinds of oranges and tangerines) is great.Grafting can keep the merit of scion variety, can utilize again the advantageous feature of stock, reaches precocity fruiting, strengthens the ability of cold resistance, drought resistance, disease and insect resistance, can also economic utilization propagating materials, increase nursery stock quantity.Be usually used in the breeding of fruit tree, forest, flowers; Also for gourd vegetables nursery.Graft technology can bring great benefit to economy.

The principal element affecting grafting survival is the affinity of scion and stock, 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.Affinity is high, and graft survival rate is high.Otherwise then survival rate is low.In general, plant affiliation is nearer, then affinity is stronger.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 is passed through grafting twig pretreatment, at the auxiliary lower grafting twig cultivated containing stock gene of nutriment, the affinity of stock and grafting twig is improved, thus improves 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 15 years tree crown top peripheral;

(2) cut from grafted branch branch 3 ~ 5 ㎝ place one wide be 1 ~ 2 ㎝, be the groove of 3 ~ 5mm deeply;

(3) on stock, cut a grafting mouth, the wide 1 ~ 2cm of interface, dark 4 ~ 7 ㎝, the stock wood chip that cuts retain, for subsequent use, described stock is chosen for without damage by disease and insect;

(4) get 3 ~ 5g stock wood chip, be milled into powder, mix with nutriment, fill up in above-mentioned grafting twig groove, carry out sealed envelope with plastic film, place 7 ~ 14 days, observed once every 1 day, do not heal completely with wound and be advisable; Described nutriment by its mass ratio be 30 ~ 55 ﹪ kinetins (KT), 10 ~ 15 ﹪ zeatin (ZT), 5 ~ 10 ﹪ 6-benzylaminopurines (6-BA), 20 ~ 25 ﹪ potassium nitrate, 10 ~ 20 ﹪ ammonium sulfate mix;

(5) unclamp plastic film, the branch processed 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) cultivated a kind of grafting twig containing stock gene, the affinity of stock and grafting twig has been improved, thus improves survival rate;

(2) simple to operate, cost is low.
