Problems solved by technology

However, in actual production, cuttings of some rose varieties are not easy to take root, or the root system produced by cuttings is poor in adaptability to soil adversity, and the plants grow poorly, so grafting can only be used.
However, during the cultivation process of grafted seedlings, the rootstock will produce a large number of sprouts, and manual removal is time-consuming and laborious.
Sprout tillers consume a lot of nutrients, seriously affecting the growth, yield and landscape value of grafted roses, and if the rootstock is not properly selected, it still cannot overcome the problem of poor adaptability of rose roots to soil adversity

Embodiment 1

[0070] Embodiment 1 Ring peeling sticking hardwood cuttings

[0071] In this embodiment, in August 2013, the thornless rose, curved thorn rose, Natebelay rose and French rose were respectively used as rootstocks, and the rose 'Jinxiuwa' was used as the scion to carry out ring skin grafting and cutting (the The rootstock and scion materials were all from the China Agricultural University Science and Technology Park), and 120 of each rootstock were grafted, and a total of 480 were grafted.

[0072] 1. Girdling and grafting

[0073] In August 2013, select biennial, strong, and pest-free vine rose branches (not cut from the rose plant), and use a circumcision knife to girdle the phloem of the rose branches by 1cm at the internodes. Injure the xylem, so as not to affect the normal growth of the branches after grafting. Then paste the rootstock bark of the same size that was girdled from the rootstock branch of the year on the girdling position. The stripped rootstock bark should ...

Embodiment 2

[0078] Embodiment 2 Ring peeling sticking green branch cutting

[0079] In this embodiment, in August 2014, the thornless rose, bent thorn rose, Natebelay rose and French rose were respectively used as rootstocks, and the rose 'Jinxiuwa' was used as the scion to carry out ring skin grafting and cutting (the rootstock of this embodiment and The scion materials were all from the China Agricultural University Science and Technology Park), and 120 rootstocks of each kind were grafted, and a total of 480 were grafted.

[0080] 1. Girdling and grafting

[0081] In August 2014, select the vine rose branches (not cut off from the rose plant) that were born in the current year, strong and free of diseases and insect pests, select the stem segments between the nodes, and use a ring cutter to gird the phloem of the rose branches by 1cm, ring Do not injure the xylem when peeling, so as not to affect the normal growth and development of the branches after grafting. Then paste the rootsto...

Abstract

The invention belongs to the technical field of Chinese rose breeding, and provides a method for cutting propagation of Chinese roses through annular veneer grafting. The method comprises the following steps that (1), girdling is carried out, specifically, a Chinese rose branch and a stock branch are girdled, and girdled bark parts of the stock are collected; (2), grafting is carried out, specifically, the collected rootstock bark part are grafted to the girdled and peeled part of the Chinese rose branches in a ring-shaped veneer-adhering mode; (3), cutting is carried out, specifically, after the Chinese rose branches and the rootstock bark are grafted and healed, the Chinese rose branches are cut off from the morphological lower part of the annular veneer, the Chinese rose branches are trimmed into cuttings with the length of 10-15 cm; (4), cuttings are treated, specifically, the annular veneer parts on the cuttings are soaked in a rooting solution; (5), cutting is carried out, specifically, the cutting ends, with the annular veneer, of the cuttings are embedded into a cutting medium; and (6), management is carried out after cutting. The obtained veneer grafting cuttings are good in rooting condition and high in cuttage survival rate, the grafting survival rate of the thorn-free multiflower roses reaches 90%, and the average rooting rate of the cuttings obtained after veneer grafting reaches 65.9%.

Description

technical field [0001] The present invention relates to the technical field of rose breeding, in particular to a method for ring-shaped skin grafting and cutting propagation rose. Background technique [0002] Chinese rose is not only one of the top ten famous flowers in my country, but also one of the four major fresh cut flowers, with a wide range of applications. Grafting and cuttings are two commonly used methods of propagation. However, in actual production, cuttings of some rose varieties are not easy to take root, or the root system produced by cuttings is poor in adaptability to soil adversity, and the plants grow poorly, so grafting can only be used for propagation. However, during the cultivation of grafted seedlings, the rootstock will produce a large number of sprouts, and manual removal is time-consuming and laborious. Sprout tillers consume a lot of nutrients, seriously affecting the growth, yield and landscape value of grafted roses, and if the rootstock is ...
