Chinese rose or rose rapid propagation method by utilizing non-thorn multiflora for no-root grafting

Abstract

The invention belongs to the technical field of plant propagation, in particular to a Chinese rose or rose rapid propagation method by utilizing a non-thorn multiflora for no-root grafting. The method includes 1, shearing a branch of an annual non-thorn multiflora, cutting the branch with the length of 15 to 20 cm, and keeping 1 to 2 buds to serve as grafting rootstocks; 2, selecting an annual or less annual Chinese rose or rose to serve as scions, cutting the Chinese rose or rose with the length of 10 to 15 cm, and keep 1 to 2 buds; 3, grafting the scions to the rootstocks by the grafting method, tying through a plastic film tightly, and cutting cuttings into growing matrix; 4, shielding, moisturizing and preventing the cuttings from freezing injury; when buds sprout in the next year, keeping the buds sprouted on the scions, and removing the buds sprouted on the rootstocks; 5, transplanting obtained cutting seedlings to the field after 45 d. By the aid of the method, survival rate is high, growth potential of the seedlings is strong, and the seedlings can be propagated annually.

Description

Background technique [0001] The invention relates to the technical field of plant propagation, and relates to a rapid propagation method of flowers, in particular to a method for rootless grafting and propagation of roses or roses using a thornless wild rose. The invention adapts to the needs of industrialization, specialization and scale, and can carry out all-weather assembly line production regardless of seasons, and greatly improves the productivity, survival rate and survival quality of seedlings. Background technique [0002] At present, the propagation methods of roses and roses mainly include cutting propagation, grafting propagation or in vitro tissue culture propagation. In vitro tissue culture propagation requires facilities and high investment. At present, cutting propagation and grafting propagation are the main propagation methods in production. [0003] After the vegetative organs of the plant are separated from the mother, they regenerate roots and shoots to ...

AI Technical Summary

Problems solved by technology

[0008] Existing Chinese rose adopts grafting propagation more, and its method mainly adopts the wild rose that has prickly to make rootstock, and method is, let rootstock take root earlier, graft the scion of Chinese rose on it again, and its seedling cycle is about three months ( 90d) and above, only 2-3 batches can be bred a year (annual production cannot be carried out), and the operation efficiency is low, it is difficult to meet the market demand

Simultaneously another defective of existing grafting method is exactly that the resistance of the thorny wild rose is weak, and the thorn on the wild rose also can have a strong impact on the workman's operation.
