How to Propagate Pinellia? A Detailed Guide to the Latest Propagation Methods

Pinellia (Pinellia ternata) is a herbaceous plant with strong vitality and is also an important medicinal herb in China. Its tubers can be used as medicine, with effects of drying dampness and resolving phlegm, and redirecting rebellious qi to stop vomiting. Its cultivation value is extremely high, and it is planted throughout the country, but its propagation method is extremely important for cultivation, so how should Pinellia be propagated? Let's find out together.

1. Seed propagation

Seed propagation is rarely used in production, and is only adopted when seedlings are insufficient or during breeding. After flowering in autumn, harvest the mature seeds about ten days later, place them in moist sand for storage, and wait for sowing. Sowing can be divided into spring sowing or autumn sowing. For spring sowing, open furrows on the prepared bed surface at a row spacing of 10-13 cm, evenly broadcast the seeds into the furrows, cover with soil and press firm. After covering with soil, cover the bed surface with grass to preserve moisture. When the seedlings emerge, promptly remove the covering grass, which is beneficial for emergence. When the seedlings grow to 10 cm, they can be planted out.

2. Corm propagation

Pinellia has strong vitality, and propagation using tubers can yield a harvest in the same year. Dig up the small tubers of the current year, mix them with moist sand, and place them in a cool place for propagation. The planting time can also be divided into spring and autumn. In spring, in March, water thoroughly before planting. Soak the tubers in wood ash, carbendazim, or potassium permanganate solution for 2-4 hours. After disinfection and sterilization, plant them separately according to size. When planting, control the row spacing at 16-20 cm and the plant spacing at 6-10 cm, and plant two pieces per hole.

3. Bulbil propagation

In summer and autumn, when the aboveground plants begin to wither while the bulbils under the leaf stalks are still growing, they can be picked for seed. Open holes on the bed surface at 6-8 cm, use two seeds per hole, and cover with about 3 cm of soil. Press down slightly. When planting, apply an appropriate amount of nitrogen and potassium fertilizer, and keep the soil somewhat moist, but not overly wet. Strengthen management after emergence. Bulbil propagation is a commonly used method among the three propagation methods of Pinellia. It germinates well, has an earlier maturity period, stable yield, and can also maintain the characteristics of the variety.
