The invention belongs to the technical field of rice planting, and particularly relates to a regulating agent for promoting flood-resistant growth of direct seeding rice and a using method thereof.The growth regulating agent is prepared from, by weight, hydroxy propyl cellulose, sodium alginate, starch, gibberellin, hydroxymethyl chitosan, inorganic salt, a bactericide, an insecticide, an oxygen producer and water; the use method comprises the following steps: mixing gibberellin, hydroxymethyl chitosan, inorganic salt, bactericide and insecticide to form a mixture A; mixing hydroxy propyl cellulose, sodium alginate and starch to form a mixture B, and then adding the mixture A to obtain the growth regulating agent; before sowing, direct sowing rice seeds are completely soaked in a growth regulating agent solution. Hydroxyl forms hydrogen bonds to form a mixed film with good performance, the slow release function is improved, the permeability of the film is improved, then rice seeds can be prevented from being
