After the seeds are harvested by the large bulb seeding method, several small bulbs are formed at the base of the seed plants. After harvesting and storage, they are planted in autumn. The dry areas can also be oversummered in situ. After germination, the original one female bulb becomes 3 to 4 female bulbs. The number of stalks in the next year is the first year of seed collection, and the second year of seed collection reduces costs, shortens the seed collection cycle, guarantees seed quality, and increases yield.
