Method for expanding propagation of virus-free radix pseudostellariae seedlings through soilless culture

The invention provides a method for expanding propagation of virus-free radix pseudosterllariae seedlings through soilless culture. The method includes the detailed following steps that virus-free radix pseudosterllariae tissue culture seedlings are cultured, virus-free miniature tuberous roots are produced, treated and transplanted, virus-free plants are cultured and managed, and the virus-free radix pseudosterllariae seedlings are produced and harvested. The method has the advantages that the virus-free radix pseudosterllariae seedlings are formed rapidly, and are large in quantity, high inyield and free of secondary virus infection and influences of natural conditions; the problems are solved that when the virus-free radix pseudosterllariae seedlings are subjected to isolating culturein field propagation expanding, workloads are large, secondary soil-borne virus infection easily occurs, and success cropping obstacles are severe, natural hazards and livestock devastation are avoided, and the production and
