Usually, cut flower varieties choose seeds to propagate. From May to June, the seeds will be collected and sown in time when they are mature. The seeds will not be dormant and will be sown immediately after harvest. When sowing, the temperature should be controlled at 15-20 ℃, so as to ensure the dark environment and germinate after 21 days. After sowing, when the seedlings grow 5-7 leaves, the aboveground part will gradually wither and yellow, and the bulbs will enter the dormancy period. At this time, care should be taken to protect the seed balls. After dormancy, re cultivation can blossom!
Specific method:
In April, the seeds of the year were collected, and then sowed in the greenhouse. The temperature was maintained at 15-20 ℃ and watered. (try to choose a larger container) after one month, the seeds will germinate and sprout one after another. Control the temperature at 15-18 ℃, and apply enough water and fertilizer. In the second year, the diameter of the seed ball can reach more than 1cm, which can be directly transplanted and planted, and can bloom in that year!
Around the big ball, 4-6 sub balls can be produced, usually the plant can be divided into three to four years. The steps are as follows: .
In summer dormancy period, the seed ball is dug out, the sub ball is directly broken off by hand, the mother ball and the sub ball are stored separately, waiting for sowing in autumn. In the first ten days of August, plant the seed ball in the flowerpot, apply enough base fertilizer, and cover 1-1.5cm above the seed ball when planting. After 10 days, it can germinate and grow. In May of the next year, the seed ball grew up and developed into a seed ball. If it is used as cut flower cultivar, the ball should be more than 8 cm long to ensure the quality of cut flower.
