Usually, cut flower varieties choose seeds for propagation. In May and June, when the seeds are mature, they should be harvested and sown in time to keep the seeds from dormancy, and sown immediately after harvest. When sowing, the temperature should be controlled at 15~2℃ to ensure the dark environment, and germination can be achieved after 21 days. After sowing, when the seedlings grow 5~7 leaves, the aboveground parts will gradually turn yellow and the bulbs will enter the dormant period. At this time, the bulbs should be carefully protected and can only bloom after replanting! Specific practice: harvest the seeds of the current year in June, then sow them in the greenhouse, keep the temperature at 15~2, and pour them thoroughly. After one month, the seeds will germinate and emerge one after another, the temperature should be controlled at 15~18 and sufficient water and fertilizer should be applied. In the second year, the diameter of the seed ball can reach more than 1cm, which can be directly transplanted and planted, and it can bloom that year!
2. propagation by dividing balls
4~6 globules can be produced around the big ball, and usually the plant can be divided after 3~4 years. The steps are as follows: during the summer dormancy period, dig out the seed ball, break it off directly by hand, and store the mother ball and the seed ball separately for autumn sowing. In early August, seed bulbs are planted in flowerpots, and base fertilizer is applied. When planting, 1-1.5 cm of soil is covered above the seed bulbs. It can germinate and grow after 1 days of watering and flooding. In May of the following year, the seed ball grew and developed into a seed ball. If it is cultivated as a cut flower variety, the bulb should grow directly to more than 8cm to ensure the quality of cut flowers.
