The invention discloses a high-germination-rate fast seedling growing method for pseudo-ginseng seeds. The method comprises the steps of pretreatment, wherein mature pseudo-ginseng fruits of 2-3 years old are picked, fruit peels are removed, the pseudo-ginseng seeds are sterilized with a 4%-6% CuSO4 aqueous solution, then the seeds are completely washed, and naturally air-dried; sowing, wherein the air-dried pseudo-ginseng seeds and wet sand are evenly mixed according to the proportion of 1:4-6 and placed in a foam box without a cap, and two layers of wet gauze are evenly laid on the upper portion of the foam box; seedling growing management and protection, wherein after sowing, the gauze covering the foam box is kept wet every day, water is sprayed into the foam box every 1-3 d to keep the humidity of the sand to be 25%-35% and temperature to be 20 DEG C to 28 DEG C; germinating and transplanting, wherein the seeds begin to germinate about 40 d after being sown, the average height of pseudo-ginseng seedlings is 2 cm to 4 cm after about 50 d, and the seedlings can be transplanted after about 70 d. The method has the advantages of being easy and convenient to manage, high in pseudo-ginseng seed germination rate and short in seedling growing time.
