What are the propagation methods for Platycodon grandiflorus?
Before understanding how to plant Platycodon grandiflorus, it is necessary to know its propagation methods. Platycodon grandiflorus is mainly propagated by seeds, but it can also be propagated by dividing the rhizome.
Planting methods for Platycodon grandiflorus
Platycodon grandiflorus is generally planted using the sowing method:
1. Seed selection and treatment
When planting Platycodon grandiflorus, it is recommended to use seeds from biennial plants. These seeds are large and plump, dark in color, and have a high germination rate, resulting in fast growth and high yield. After selecting the seeds, place them in warm water at 50-60°C, stir continuously, and remove any impurities such as mud and damaged seeds. After the water cools, soak for 12 hours, or use a 0.3% potassium permanganate solution to soak the seeds for 12 hours to improve the germination rate.
2. Soil requirements
Platycodon grandiflorus is not picky about soil fertility; it can grow well in average fertile soil, but plants in fertile soil tend to be taller and have more flowers. For cut flower cultivation, the soil should be deeply cultivated and ample base fertilizer applied, with top dressing applied 2-3 times before flowering to promote stem height growth and bud formation.
3. Sowing time and method
It can be sown in autumn or spring. Platycodon grandiflorus seeds are small, so the land should be carefully prepared before sowing. Make a horizontal furrow on the ridge surface with a row spacing of 15-20 cm, a furrow depth of 1.5-2 cm, and a播幅 width of about 10 cm. The bottom of the furrow should be flat, and after sowing the seeds, cover them with a thin layer of ash.
4. Water and fertilizer
When the seedlings of Platycodon grandiflorus grow to about 10 cm, water should be controlled appropriately. Generally, water every 3-4 days in spring and autumn, water every evening at around 5 pm in summer, and do not water in winter. The key point for fertilizing Platycodon grandiflorus is before and after flowering. Fertilize with calcium superphosphate 1-2 times a year before flowering to ensure bright flower color. After the flowers fade, cut off the stems and apply a liquid fertilizer made from soybean cake to promote root growth.
5. Daily management
(1) Weeding and top dressing: After the seedlings have emerged, promptly cultivate the soil, remove weeds, and apply fertilizer to promote healthy growth of the seedlings.
(2) Thinning and transplanting: When the seedlings are 3 cm tall, thin them promptly, and when they are 6 cm tall, transplant them at a spacing of 5-6 cm.
(3) Pruning: If you want Platycodon grandiflorus to bloom a second time, prune promptly after the first bloom and strengthen fertilization and water management. It can bloom again for the National Day.
(4) Loosening the soil: When the seedlings have grown 4 leaves, remove the weak seedlings and loosen the soil to ensure sufficient nutrients in the soil.
