The invention belongs to the technical field of plant seedling culture, and particularly relates to a method for grafting and culturing colorful osmanthus, which comprises the following steps: (1) processing a mother tree; (2) treating stock seedlings; (3) scion treatment; (4) and (4) grafting treatment. The method adopts the nutrient solution and the foliar fertilizer to pre-culture the colorful cinnamon tree and the stock seedling, not only has the effect of strengthening the seedling, but also can improve the compatibility of the stock seedling and the grafted branch; the grafting liquid prepared from the nutrient solution is used for treating scion cuts and stock cuts, so that the cell division at the cuts can be promoted, the affinity of the scion cuts and the stock cuts can be improved, and the formation of calluses can be promoted. The grafting seedling raising technology provided by the invention can effectively improve the affinity between the stock seedling and the scion, and reduces the problem of expansion of the grafting opening caused by insufficient affinity between the stock seedling and the scion; meanwhile, the formation of callus at the grafting opening of the grafted seedling can be promoted, and the grafting survival rate is improved. |
