How to Propagate Pinellia? Introduction to Common Propagation Methods
Pinellia (Pinellia ternata) is a herbaceous plant with strong vitality and is also an important medicinal material in China. Its tubers can be used as medicine and have the effects of drying dampness and resolving phlegm, and redirecting qi downward to stop vomiting. Its cultivation value is extremely high, and it is planted all over 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, about ten days later, harvest the mature seeds and place them in wet sand for storage until sowing. Sowing can be divided into spring sowing or autumn sowing. For spring sowing, open furrows on the prepared seedbed at a row spacing of 10-13cm, evenly broadcast the seeds into the furrows, cover with soil and press firm. After covering with soil, spread grass on the seedbed to preserve moisture. When the seedlings emerge, promptly remove the covering grass, which is beneficial for emergence. When the seedlings grow to 10cm, they can be transplanted.
2. Corm propagation
Pinellia has strong vitality, and propagation by tubers can yield a harvest in the same year. Dig out the small tubers of the current year, mix them with wet 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 16-20cm and the plant spacing at 6-10cm, 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 planting. Open holes on the seedbed at 6-8cm, use two seeds per hole, and cover with about 3cm of soil. Press down slightly. When planting, an appropriate amount of nitrogen and potassium fertilizer can be applied, and the soil should be kept at a certain humidity, but it should not be too wet. Strengthen management after emergence. Bulbil propagation is a commonly used method among the three propagation methods of pinellia. It germinates neatly, has an earlier maturity period, stable yield, and can also maintain the characteristics of the variety.
