Growing environment of Pinellia ternata

Published: 2024-12-23 Author: mysheen

Last Updated: 2024/12/23, Pinellia ternata is a shallow root plant, like fertilizer, originally wild in wet and loose and fertile sandy loam or humus soil. Like mild, humid climate and shady environment, afraid of drought, avoid high temperature, it is appropriate to grow in semi-overcast and semi-sunny environment in summer; it is more suitable to grow when soil water content is 20%-40%. Drought and lack of water are easy to pour seedlings, generally with the change of growth environment, seedlings can be inverted one or three times a year. For Pinellia ternata, on the one hand, it is a kind of adaptation to the bad environment, and more importantly, it increases the number of bulbs.

Pinellia ternata is a shallow root plant, like fertilizer, the original wild was born in moist and loose fertile sandy loam or humus soil. Like mild, humid climate and shade environment, afraid of drought, avoid high temperature, summer should grow in semi-shady and semi-sunny environment; soil moisture content is more suitable for growth when 20%-40%; drought and water shortage are easy to fall seedlings, generally with the change of growth environment, seedlings can fall 1~3 times a year. For Pinellia ternata, on the one hand, it is an adaptation to bad environment, and more importantly, it increases the number of bulbils, that is, it carries out asexual reproduction with bulbils as propagation materials.

Pinellia ternata germinates at 8~10℃ and sprouts at 15℃. The optimum temperature for growth is 15~26℃. It grows slowly above 30℃. When it exceeds 35℃ and lacks water, seedlings begin to fall. When autumn is cool, the seedlings come back and continue to grow. After autumn, when the temperature is lower than 13℃, they begin to wither.

Tubers, bulbils and seeds of Pinellia ternata have no physiological dormancy. Seed life is 1 year.

For tubers sown in winter or early spring, petioles are sent out when the ground temperature reaches 10-13℃ at 1 - 5 cm of the ground surface. At this time, if the ground temperature is lower than the ground temperature for several days, petioles will flourish in the soil and grow a generation of bulbils. The longer the difference between ground temperature and air temperature lasts, the longer the petiole grows in the soil, the bigger the underground bulbils grow. When the temperature rises to 13-15℃, the petiole will erect and grow out of the ground surface.
