Abstract: In order to improve the propagation efficiency of Alstromeria aurantiaca, the shoot apex and leaf as explant materials were used to compare the explant induction medium and rooting medium in different experiment time, experiments on seed germination and plant division propagation were carried out, and a plant rapid propagation propagation system was established. The results showed that the optimal one is MS 6 - BA 5.0 mg/L 1.0 mg/L NAA for shoot apex original culture medium; Rooting culture is 3/4 ms 0.2 mg/L NAA IBA 0.5 mg/L; The best seed germination matrix is peat: sand: vermiculite = 1:1:1, The ideal growing environment is (22±2) ℃ around 3 weeks, and then the refrigerator around 5 ℃ about 3 weeks; the most appropriate matrix is peat soil: perlite: vermiculite = 3:2:1. Division propagation Plant should select those strong, colorful, no diseases and insect pests, and the temperature should be controlled in (22±2) ℃.
