The invention provides a method for raising seedlings of camellia chrysantha plants by top grafting. By the aid of the method, study for supporting technologies for raising the seedlings of the camellia chrysantha plants by top grafting is carried out in the aspects such as scion, rootstock selection and processing, the grafting time, culture conditions and matters needing attention, and in order to achieve purposes of increasing a survival rate and cultivating excellent strains with both ornamental value and medicinal value, a plurality of key links are improved in an emphasized manner and include that (1), large tea-oil trees at tree ages of 60-80 years are selected as rootstocks; (2), scion cuts are subjected to wax sealing processing in a scion storage period; and (3), as the rootstocks are large and are high in drying degree and crowns of the rootstocks are large, an independent spatial protection measure is adopted after grafting, in other words, protective covers are manufactured according to sizes of the trees. The method has the advantages that problems of low quantity of existing wild camellia chrysantha, extremely low fruit rate, long seedling stage duration, low emergence rate and the like in the prior art are solved, the reproductive cycle of camellia chrysantha can be shortened, seedlings can be yielded from a garden in a period ranging from half a year to a year, the survival rate can reach 95% at least, and the excellent strains with both the ornamental value and the medicinal value can be cultivated within the shortest time.
