The invention discloses a method for improving germination of stevia rebaudiana seeds, which relates to a crop seed treatment technique in the technical field of agriculture. The method comprises the following steps of: selecting and sterilizing seeds, preparing 6 to 8 percent aqueous solution of polyethylene glycol 4000, soaking the seeds into the prepared solution at the temperature of between 20 and 30 DEG C for 24 to 48 hours, then filtering the seeds, cleaning the seeds by using clear water, and airing the seeds for later sowing. In the method, the used polyethylene glycol is generally recognized that molecules of the polyethylene glycol can change biological membrane structures of various cells in cell engineering so that lipid molecules on a plasma membrane at a contact point of two cells are dispersed and recombined, can change the osmotic regulation capability of plants on plant physiology and are favorable for absorbing nutrition and inducing the activity of stimulation cells. The method can remarkably improve the capability of resisting adverse situations when the stevia rebaudiana seeds are germinated so that the stevia rebaudiana seeds still maintain higher germination rate and germination energy in adverse situation harm and the seedlings have good quality.
