The invention belongs to the technical field of flowering phase regulation and control of ornamental plants, and particularly relates to application of a saturated
acetylene aqueous solution in promoting flowering of
clivia miniata, and 200-600 mL of the saturated
acetylene aqueous solution is applied to the
clivia miniata every time in the growing period in winter.
Calcium carbide is rapidly decomposed into
acetylene and
calcium hydroxide when encountering water, the reaction is violent, a large amount of acetylene generated by the reaction is dissolved in water, namely the
calcium carbide aqueous solution can obtain an acetylene saturated solution, and the saturated acetylene aqueous solution does not have an inhibition effect on growth of pineapples, but does not have an obvious inhibition effect; the saturated acetylene aqueous solution can promote the flowering of the
clivia miniata, so that the method for promoting the flowering of the
clivia miniata by using the saturated acetylene aqueous solution is provided.
