Guangxi zedoary florescence control method

The invention discloses a Guangxi zedoary florescence control method which comprises the following steps: (1), seedball treatment: collecting, screening, grading, cleaning, sterilizing and then airing Guangxi zedoary seedballs; (2), refrigeration: refrigerating the Guangxi zedoary seedballs in a refrigerator with the relative humidity of 70 percent to 95 percent at 13 DEG C to 20 DEG C for 30 days to 60 days; (3), germination: taking the seedballs out of the refrigerator and putting the seedballs into a greenhouse with the relative humidity larger than or equal to 90 percent at 25 DEG C to 30DEG C for germination for 10 days to 30 days; and (4), flower culture: putting the germinated seedballs in a culture chamber for culture until bud bodies swell, and placing seedballs capable of forming blossom buds in natural conditions for culture when mauve inflorescences occur in green bracts but are not exposed. The method enables Guangxi zedoary which originally blooms between April and Juneand between July to Septem
