Growth habits of Notopterygium

Notopterygium notopterygium is produced in Shaanxi, Sichuan, Gansu, Qinghai, Xizang and other places, growing in forest margins and thickets at an altitude of 2000 to 4000 meters.

Reproductive techniques of Notopterygium

1. Seed reproduction: mature seeds are harvested in autumn, dried in the sun, and direct seeded in spring after corner freezing. Holes are opened according to row spacing of 33 cm, hole spacing of 23 cm, depth of 5 cm, more than 10 seeds per hole, covering compost or humus soil of about 1 cm and 2 cm, and watering. Use about 15 kilograms of seeds per hectare.

2. Rhizome propagation: when harvested in autumn or spring, the rhizome with buds is selected and cut into small segments, and the multiplication section has 1-2 buds. Strip planting, trench according to the row spacing of 33 cm, ditch depth 15 cm, width 15 cm, put the rhizome horizontally in the ditch, every 8 cm 10 cm, cover soil fertilizer or fine soil 14 cm 16 cm, watering.

Planting techniques of Notopterygium
