The invention discloses a ludisia discolor rapidly culturing method. The ludisia discolor rapidly culturing method can obtain a large quantity of high-quality ludisia discolor seedlings through capsule sterilization, seed germination, strong seedling culture, enrichment culture, rooting culture and transplantation. The ludisia discolor rapidly culturing method can culture ludisia discolor with high efficiency; the cultured ludisia discolor seedlings are high in planting rate and quality, good in post-transplantation adaptability and safe and environmentally friendly when applied as medicinal plants; by means of biological technology, the demands of commercialized production can be met within a short time, and technical support can be provided for scale production of ludisia discolor of enterprises. Meanwhile, the ludisia discolor rapidly culturing method is simple and easy to implement, refined in process, good in sterilizing effects, rapid in culture, high in planting rate and low incontamination rate and can effectively reduce the culture cost, thereby greatly improving the planting rate and the working efficiency and saving resources.
