The price of Tiannanxing seeds is about 120-150 yuan per jin, but it varies according to the quality, variety, origin and market of the seeds. Tiannanxing propagation is mainly tuber propagation, but also seed reproduction, like moist, loose, fertile soil and environment, like water and fertilizer, tuber is not freeze-resistant, but the seedlings germinated by seeds in the same year, the seedlings only have three leaflets in the first year. after the second and third year, the number of leaflets increased step by step and was more resistant to cold.

Sowing method of Artemisia angustifolia

1. Seed collection: the seeds of Artemisia angustifolia are ripe in early August, and the berries are collected and washed in clean water to remove the pulp. The seeds are fished out and sowed in autumn immediately.

2. Sowing method: dig a shallow ditch on the whole seedbed according to the row spacing of 15cm to 20cm, then sow the seeds into the ditch, and cover the soil flush with the border surface.

3. Post-sowing management: after sowing, water should be watered once, and then keep the bed moist. Usually, seedlings can emerge in 10 days, and seedlings will be fixed when the height is 6-9 cm.
