Hybridization method of curcuma plants

The invention discloses a hybridization method of curcuma plants. The hybridization method comprises the steps of hydroponic flowering, castration, stigma treatment, pollen treatment and pollination.According to the hybridization method, a zingiberaceae hydroponic hybridization method is created for the first time, so that land resources are saved, and the space utilization rate is increased; theproblem that the hybridization time of different turmeric species is limited due to inconsistent flowering stages or short flowering stage overlapping time is solved; and a prepared improved Hoagland's nutrient solution A can shorten the fruit development period and improve the setting rate, an improved Hoagland's nutrient solution B can prolong the single-flower pollination period and the inflorescence pollination period, and pollen liquid can increase the number of seeds. The hybridization method provides a technical basis for promoting curcuma crossbreeding work, provides reference significance for creating hydropo
