The invention discloses a method for efficiently grafting an osmanthus tree onto a ligustrun lucidum tree. The method comprises the following steps: (1) treating a scion; (2) selecting a rootstock; (3) processing the rootstock before grafting; (4) determining the grafting time: time for grafting is selected in middle March of next year; (5) selecting a grafting method. Compared with an osmanthus grafting technology in the prior art, the method provided by the invention has very significant advantages, and osmanthus grafting is realized through the technical scheme that according to the grafting method, a prepared soaking agent is used to treat the scion, so that the affinity of the scion and the rootstock is improved, the activity of the scion is improved, the tissue healing speed is accelerated, and pest infection during healing is prevented; the stump of the ligustrun lucidum tree is used as the stock because the ligustrun lucidum tree is coldproof and drought-enduring, and developed in root; the ligustrun lucidum tree is very strong in life force, and can resist pests and diseases, so that the scion growing on the ligustrun lucidum stock is unlikely to suffer from yellow leaf disease, scale insect disease and powdery mildew, and the grafting survival rate is expected to reach 98% or above.
