The invention discloses an aboveground seedbed cultivation method of a cut gerbera flower. The method comprises requirements on an aboveground seedbed, filling of a substrate, transplantation and management. By virtue of an appropriate substrate ratio and layered filling of the seedbed provided by the invention, transplanted gerberas have the advantages of high survival rate, high growing rate, vigorous growth and the like; the use of the aboveground seedbed facilitates replacement and sterilization of the substrate, and reduces influence of continuous cropping obstacles on production of the cut gerbera flower; and an adopted measure of slight swelling of the substrate at a seedling planting position facilitates final-period management to reduce occurrence of diseases, and avoids soil layers from hindering growth and development of leaves and buds during growth at the same time, thereby improving the flower production rate and cut flower quality.
