The invention relates to a seedling raising technology for camellia oleifera seed seedlings of extremely small population plants. The seedling raising technology comprises the following steps that naturally fallen mature fruits are collected in a natural population distribution place of Cinnamomum camphora, and manual extruding is carried out to remove aril to obtain seeds; mixed soil of humus soil and sandy soil is used as a matrix, carbendazim is used for blocking soil for disinfection, and the obtained matrix is used for manufacturing a seedbed in a greenhouse and is thoroughly watered for standby application; dry seeds need to be soaked in clear water before sowing, fresh seeds are not used, ditching is carried out on a seedbed during sowing, seed umbilicus faces downwards, one row of seeds are arranged in one ditch, soil covering outside the ditches is carried out again after one row of seeds is sown, and dibble seeding, leveling and pine needle or fallen leaf covering are sequentially carried out after sowing of the whole bed is completed; and proper indoor temperature, humidity and soil humidity are kept, conventional management is carried out until the seeds sprout, meanwhile, seedbed coverings are removed, the seedlings are transplanted into a nutrition bag when the seedlings grow to 4-5 true leaves, maintenance is carried out for 8 weeks, and outdoor seedling hardening is carried out for 26 weeks so as to be used for second field transplanting. Compared with a traditional artificial breeding method, the method has the advantages that the emergence rate is more than 4 times, and a technical support is provided for effectively saving the species.
