The invention provides a method for rapid cultivation of lily bud scale bulb-lets. The lily bud scale bulb-lets are cultivated in the soil after the bud scale bud forcing treatment, the expansion treatment of the bud scale bulb-lets and the low-temperature treatment of the bud scale bulb-lets. The method can lead the lily bud scale bulb-lets to grow stalks in the same year, and the stalk growing rate of the lily bud scale bulb-lets can achieve 50-70 percent, thereby greatly shortening the cultivation cycle of lily seedballs to 2 years from 3 years; in addition, the lily bud scale treated by the method can faster generate the bulb-lets, the bud scale bulb-lets have the advantages of even size, greater generation of the bulb-lets and the like, the girth diameter of the bulb-lets is 2-3.5cm, the average number of the bud scale bulb-lets is three, and the bulb-lets treated by the method have more tidy emergence after being cultivated in the soil, thereby facilitating the cultivation and the management.
