[0036] Some embodiments of the present invention also provide a preparation method of a corn seed initiator, which includes: dissolving melatonin and abscisic acid in an alcoholic organic solvent, and then distilling to volume with water, so that in the aqueous solution after distilling The mass percentage of melatonin is 0.015%-0.025% and the mass percentage of abscisic acid is 0.018%-0.028%, wherein the alcoholic organic solvent can be ethanol, ethylene glycol, etc., preferably ethanol.
[0037] Some embodiments of the present invention also relate to a method for promoting low-temperature germination resistance of corn seeds, which includes: using the above-mentioned corn seed initiator to perform surface treatment on corn seeds before sowing.
[0038] Surface treatment of the corn seeds can enable the corn seed initiator to enter the corn seeds from the surface of the corn seeds to act on the corn seeds and promote the probability of germination at low temperatures.
