1. Seeding and reproduction: Seeding belongs to sexual reproduction and is mainly used for breeding. The method is: harvest the seeds in autumn and store them until sowing in the next spring. Germinate about 20-30 days after sowing. Appropriate shading should be provided at seedling stage. In autumn, the underground part has formed small bulbs, which can be dug out and planted separately. Due to different species, some seedlings bloom in three years, and some need to be cultivated for many years before flowering. So this method is not suitable for families.

2. Small bulb method: If it is necessary to cultivate 1 plant or several plants, this method can be used. Usually there are some small bulbs around the stem disk of old bulbs. When lilies are harvested from September to June, these bulbs can be separated and stored in indoor sand for the winter. Potted seeds were planted in the following spring. 10 When cultivated from September to June in the third year, it can grow into large bulbs and cultivate into large plants. This method has a small amount of reproduction and is only suitable for family pot breeding.

3. Scale cutting method: This method can be used for medium-sized replication. Dig out the bulbs in autumn and break off the plump scales on the old scales one by one. There should be a small part of stem disc at the base of each scale, which is slightly dried in the shade, and then cut into flower pots or shallow wooden boxes, which are filled with river sand (or vermiculite), so that two-thirds of scales are inserted into the substrate, and the substrate keeps a certain humidity. Under the condition of about 20 degrees, about 1 month and a half, the scale injury will take root and sprout. In winter, the humidity should be kept at about 18 degrees, and the river sand should not be too wet. By the next spring, the scales can grow into small bulbs, which can be divided into blocks, planted in pots, carefully managed and cultivated for about 3 years before flowering.

4. Pearl bud method: Pearl bud method is only applicable to a few varieties. Such as lily, yellow iron cannon, etc. , often use this method. The practice is: take down the small bulbs (also called "small bulbs", which have fully grown in summer, but have not yet fallen off) formed in the axils of stems and leaves on the ground and cultivate them. It usually takes 2-4 years from growing into a big bulb to flowering. In order to promote the propagation of more bulblets, after flowering, the aboveground stems can be crushed and buried in shallow soil-the aboveground stems can be divided into small segments of 3-4 leaves, and the shallow buried stems can grow bulblets in the axils of leaves.
