Method for promoting seed stem budding of Guangxi curcuma zedoary

The invention relates to the field of crop cultivation, in particular to a method for promoting germination of seed stems of Guangxi curcuma zedoary, which comprises the following steps: (1) cutting tubers of the Guangxi curcuma zedoary; (2) preparing a bud promoting agent, wherein plant growth regulators comprise 1.0 to 50.0 mg/L of KT, 1.0 to 50.0 mg/L of GA, 0.5 to 10 mg/L of IAA, 0.3 mg/L of DMSO and 500 times of carbendazim; (3) soaking the seed stems in the step (1) in a germination promoting solution for 10-60 minutes, fishing out the seed stems, and airing surface moisture; (4) the seed stems are planted on the prepared furrows, the furrows are covered with black films, the budding time is the last ten days of April, budding is completed within 10-30 days, the number of buds is 2-5, and the budding rate is 72.3%-98.7%. The germination promoting agent has the following triple effects: the germination of Guangxi curcuma zedoary buds is promoted; bud strengthening; tubers are sterilized and prevented fro
