Rejuvenating method for tissue culture of superior nanmu trees

The invention belongs to the technical field of cultivation of nanmu seedlings, and relates to a rejuvenating method for superior nanmu trees. The method includes the steps of grafting and rejuvenating of superior nanmu tree materials, explant sterilization, primary culture, test tube grafting and rejuvenating, subculture multiplication culture, root induction, seedling hardening and transplanting. The rejuvenating method for tissue culture of the superior nanmu trees has the advantages that the superior nanmu trees have high twig cuttage survival rate and strong asexual reproduction ability,and the like; the problem of difficulty in collection of seeds, branches and roots of the superior nanmu trees is solved, the rejuvenation cycle of the superior nanmu tree materials is shortened, andthe rejuvenation efficiency is improved greatly; therefore, a new way is provided for rejuvenation of superior nanmu trees, and the nanmu breeding process is promoted vigorously. 本发明属于楠木育苗技术领域，涉及种楠木优树的幼化方法，所述方法包括楠木优树材料的嫁接复壮步骤，
