Camellia oleifera grafting propagation method

Abstract

The invention discloses a camellia oleifera grafting propagation method. The method includes steps: S1, scion selection, to be specific, taking semi-lignified spring shoots, growing in the current year, of valuable and rare or good-variety camellia oleifera trees as scions; S2, scion treatment, to be specific, soaking cut faces of the scions in a growth synergist at 15-25 DEG C for 0.5-1h, whereinthe growth synergist comprises 5-20Mug / L plant antibacterial peptides aqueous solution, 40-80mg / L lysozyme aqueous solution, 5-10mg / L 2-dodecylene diacid aqueous solution, 20-30mg / L compound sodium nitrophenolate aqueous solution and 100-150mg / L abelmoschus manihot extract aqueous solution; S3, rootstock selection and treatment; S4, grafting; S5, after-grafting management. By adoption of common camellia oleifera as rootstocks for grafting of valuable and rare or good-variety camellia oleifera, the population quantity of endangered valuable and rare camellia oleifera can be remarkably increased by means of vegetative propagation to guarantee normal annual rate of increase, and a rich camellia oleifera gene resource library can be established, such as camellia luteoflora which is a new species of camellia oleifera; high-yield, stable-yield, high-oil-yield and high-oil-quality camellia oleifera fruits can be obtained, such as Ganshi 84-8.

Description

Technical field [0001] The invention belongs to the technical field of camellia oleifera planting, and specifically relates to a method for grafting and propagation of camellia oleifera. Background technique [0002] Grafting propagation is the use of a part of plant vegetative organs, which is transplanted to another plant with a certain affinity, and the cambium at the junction is healed, so that the catheter and sieve can communicate with each other to form asexual reproduction of a new individual method. At present, the grafting technology of Camellia oleifera has matured day by day, but the survival rate of grafting is still not high. The main reasons are: 1) After grafting, the wound is susceptible to microbial and virus infection and damage, causing the grafting site to rot and disease; High, slow wound healing; 3) slow growth of grafted buds. Summary of the invention [0003] Aiming at the shortcomings of the prior art, the purpose of the present invention is to provide ...

Problems solved by technology

At present, the grafting technology of camellia oleifera has become more and more mature, but the survival rate of grafting is still not high. The main reasons are as follows: 1) the wound after grafting is susceptible to infection and infringement by microorganisms and viruses, resulting in rot and disease at the grafting place; 2) the callus is not active. High, slow wound healing; 3) Slow growth of buds
