Propagation methods of Pinellia ternata

Pinellia ternata is an important medicinal material in the treasure house of Chinese traditional medicine, which is produced only in China and Japan in Asia. There are three ways of propagation and cultivation of Pinellia ternata: underground bulb, bulb propagation and seed propagation.

Bulb propagation

Cold Dew before and after digging bulbs, choose smaller seeds, with wet soil buried in a cool and ventilated place, to the next year before and after the Qingming Festival, according to the distance of 10 × 6 cm, transferred to the field, not too deep, an inch can be, the ground temperature 15Muk 20 ℃, half a month can emerge, mu seed 40 to 50 kg.

Bulblet propagation

In summer and autumn, after the local upper part withered, the bulbil under the leaf stem is growing, so it can be collected and planted, according to 6 to 8 cm hole opening, 2 hole sowing, soil covering 3 cm, slightly compacted, applying appropriate amount of phosphorus and potassium fertilizer to keep it dry and wet properly, and strengthen the management after emergence. Bulblet propagation is the main way of reproduction of Pinellia ternata at present, with reliable germination and early maturity.

Seed propagation

Select two-year-old Pinellia ternata seeds, prepare the land before and after the Qingming Festival, sow them in frogs at a row spacing of 8 to 10 cm, cover the seeds with soil of about 2 cm, and then water them after being firm, so that the seeds are evenly on the ground, covered with wheat straw or straw, keep moist, remove weeds after emergence, 6 cm time seedlings, weeding, strengthen management, and sow about 3 jin per mu. No matter which method is used to propagate, it is necessary to strengthen field management, apply sufficient basal fertilizer, remove scape and increase yield without leaving seeds.
