A Detailed Guide to the Latest Methods for Treating Pinellia ternata Seeds

How should Pinellia ternata seeds be treated before sowing? The seed-sowing method for Pinellia ternata is usually used when seedlings are insufficient or for breeding. About ten days after flowering in autumn, when the spathe withers, the mature seeds are harvested, stored in wet sand, and kept for sowing. Sowing is done in two seasons, spring and autumn. In spring, on prepared beds, open furrows at a row spacing of 10-13 cm, scatter the seeds evenly into the furrows, cover with 10-13 cm of soil, and cover with rice straw to preserve moisture. When the seedlings reach 10 cm in height, transplant them.

Treating Pinellia ternata seeds before sowing plays a major role in preventing and controlling pests and diseases, increasing the germination rate, and achieving uniform, complete, and strong seedlings. It is the primary prerequisite for stable and high yields, and can generally increase yields by 5%-20%. The methods for treating Pinellia ternata seeds are introduced below:

First: Before sowing, soak the seeds in a 3-fold dilution of 50% carbendazim plus 40% fosetyl-aluminum solution (yield increase is significant).

Second: Soak the seeds separately in 300-fold diluted rice vinegar, 50 mg/L potassium permanganate, and 5% plant ash solution (to prevent root rot). 

In addition, Pinellia ternata also has a very extensive propagation method. Pinellia ternata has a very strong reproductive capacity, and on land where it has been planted, it grows continuously year after year, so there is no need to sow it separately. With management, it can be harvested, but the yield is low.
