摘  要:
[Objective] To select the optimum hormones ratio and concentration for the scale cutting propagation of Lycoris plants, so as to provide basis for the production of Lycoris plants in winter. [Method] 4 concentrations of IBA and NAA were combined randomly into 16 formulas. [Result] Different concentrations of IBA and NAA have a certain effect on the multiplication coefficient, bulb mean weight and average rooting number, and the concentration of NAA-IBA mixed solution was proved to be the best in the range of 25-50 mg/L; under this condition, the multiplication coefficient of Lycoris plants was higher with lower bulb mean weight. [Conclusion] It is feasible to carry out scale cutting propagation of Lycoris radiate and Lycoris sprengeri in winte.
