The invention discloses a seedling raising method for Camellia oleifera by grafting, belonging to the technical field of agricultural planting. The seedling raising method comprises the following steps: seedling orchard preparation, shade shed building, rootstock cultivation, scion preparation, grafting, and grafted seedling planting management, wherein a base fertilizer containing the following raw materials is applied in the process of seedling orchard preparation: decomposed farmyard manure, biogas residue, Chinese medicine residue, distiller's grains, humic acid, Camellia oleifera seed cakes, fish meal, potassium sulfate, calcium phosphate, magnesium sulfate, zinc sulfate, copper sulfate, ammonium hydrogen carbonate, sodium molybdate, enzyme microorganisms and quicklime; and a healingagent containing the following raw materials is smeared at the edge of the joint position of a scion and a rootstock in the process of grafting: gelatin, hydroxyethyl cellulose, vegetable oil, sucrose, aloe juice, pomegranate peel, matrine, 6-benzyl aminopurine, naphthylacetic acid, erythromycin, diethyl aminoethyl hexanoate, boric acid, potassium dihydrogen phosphate and carbendazim. The seedlingraising method provided by the invention solves the problem of low survival rate of grafted Camellia oleifera seedlings in the cultivation process of Camellia oleifera seedlings through a traditionalgrafting method.
