Method for rapidly inducing dendrobium candidum to flower in test tube

The invention discloses a method for rapidly inducing dendrobium candidum to flower in a test tube. The method comprises the following steps: step 1, inoculating a tissue culture seedling of the dendrobium candidum to a strong seedling culture medium, culturing for 25 to 30 days at temperature of 24 to 26 DEG C and humidity of 35 to 45 percent and under light of 14 to 16 hours every day to obtain a robust dendrobium candidum seedling in the test tube; step 2, inoculating the robust dendrobium candidum seedling in the test tube of which the plant height is 3 to 5 cm long to a flower bud induction and flowering culture medium, and culturing for 70 to 90 days at temperature of 24 to 26 DEG C and humidity of 35 to 45 percent and under the light of 14 to 16 hours every day to obtain a flowering plant in the test tube. The method is simple and easy to implement; flowering time can be artificially controlled to get rid of limitation of a season on the flowering phase of the dendrobium candidum; a flowering cycle is
