How do mountain lilies reproduce

(2) The bulbs on the disease-free plants are collected during bulb propagation and harvesting, soaked in 500 times benomyl or captan aqueous solution for 30 minutes for disinfection, and then sown according to the row spacing of 20 cm x 5 cm. A part of bulbs reach the planting specification in one year, and are transplanted into production fields as seeds. Those that are too small need to grow for 2 years. The bulbs produced by sexual reproduction and asexual reproduction need to be planted in the production field. Production fields can be bed or ridge. Bed cultivation is planted at a row spacing of 20 cm x 5 cm; ridge cultivation is 50 cm)(5 cm double row planting, ridge cultivation is convenient for intertillage and weeding.
