The invention discloses a Nuccio's bella rosa camellia cutting seedling-raising method. The method includes the following steps: selecting red soil as a cuttage medium; selecting annual strong healthy semi-lignified branches without disease and pests as scions in the middle-last ten days of June, and processing the scions with a rooting agent, and performing cuttage, wherein the cuttage density is 4 cm X 8 cm; covering a greenhouse with a sunshade net after cuttage, controlling the temperature of the greenhouse at 20-30 DEG C and the humidity of the green house at 70-80% by folding and unfolding the sunshade net and ejecting water, and performing disease and pest control; and allowing the scions to take roots in 1 month after cuttage, transplanting the rooted seedlings to nutriment pots after 2 months, performing seedling training for 3 months, and transplanting the seedlings to a field. According to the characteristics of the Nuccio's bella rosa camellia, the red soil is used as the cuttage medium, 600-1000 ppm of 3-Indolybutyric acid is used to process the scions, twig cuttage seedling raising is performed in a small arc shed, the average root length and the root number of the cuttage seedlings of the Nuccio's bella rosa camellia can be remarkably increased, and the survival rate of the transplanted seedlings is greatly improved.
