The invention provides carnation high-efficiency rootone which is characterized by containing the following materials according to weight part: 10 parts of rhodofix, 1-2 parts of seradix, 80-120 parts of mildothane, 15-30 parts of streptomycin and 6000-6400 parts of talcum powder. In the invention, aiming at the problems of root rot and stem rot of the carnation easily harmed by epiphyte and bacteria and being combined with the characteristics that roots produced by rhodofix NAA induction are less in quantity and thick and adventitious roots produced by seradix IBA action are thin and long, NAA and IBA are mixed in the rootone, and meanwhile, mildothane used for sterilizing and agricultural streptomycin are added; therefore, the rooting ratio of the carnation is high, the growing roots are long and thick, the antibiosis and disease-resisting capacity is enhanced, and the root rot ratio is greatly reduced, and the invention has the advantages of tidy rooting, high field production survival rate, convenient usage, low cost, good effect, and the like and is very convenient for the growth of the carnations.
