Rapid propagation seedling raising method for arrowroot mosaic

The invention discloses a rapid propagation seedling raising method for arrowroot mosaic. The method comprises the following steps: disinfecting the base part of the stem section of the arrowroot mosaic with a mercury bichloride solution with the concentration of 0.1-0.2%; then carrying out segmentation treatment, and inoculating to a proliferation induction culture medium for culturing after segmentation, so as to obtain mosaic aseptic seedlings; the proliferation induction culture medium comprises an MS culture medium, 6-BA, NAA, white granulated sugar and carrageenan; inoculating the mosaic aseptic seedlings into a rooting induction culture medium for culturing to obtain mosaic arrowroot rooting test-tube seedlings; the rooting induction culture medium comprises a 1/2 MS culture medium, AC and/or NAA, white granulated sugar and carrageenan; and transplanting the rooting test-tube plantlet of the arrowroot mosaic into a matrix for new root germination. The method has the advantages of small damage to stock
