The method for raising seedlings of Rhizoma Polygonatum, the steps include: preparation of explants of Rhizoma Rhizoma Diannensis, culture for eliminating browning, callus induction, adventitious bud generation and proliferation culture, dark culture for promoting rhizome growth, rejuvenation culture of test-tube plantlets, rooting culture, hardening of seedlings Cultivation; the beneficial effect is: the Yunnan gold explants are carried out in the substratum A in the transfer culture of every 7 days, and the effect of removing the browning phenomenon occurring in the tissue culture process is remarkable; simultaneously carry out callus induction, cluster bud generation and Proliferation culture improves the reproduction efficiency, the reproduction coefficient can be increased to more than 8.67, and the tissue culture time can be shortened to 45 days; in the dark culture stage, the rhizome of Polygonatum yunnanensis is greatly improved, and the survival rate can reach more than 95%; the invention is divided into stages Four kinds of media are used for transfer culture, which overcomes the problem of easy breeding of fungi and accumulation of viruses when Polygonatum yunnanensis is used for group cultivation of seedlings. The cultivated seedlings have strong adaptability and stress resistance, which reduces the pollution rate of group cultured seedlings and improves To ensure the stability of species.
