Growing environment of Pinellia ternata
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.

Efficient Cultivation Techniques of Pinellia ternata
Pinellia ternata, araceae pinellia plants, for commonly used traditional chinese medicine. In recent years, Pinellia ternata protein has been found to have anti-early pregnancy and anti-tumor effects. It is one of the Chinese herbal medicines in short supply for many years. Xihe County of Gansu Province is a suitable planting area for Pinellia ternata. The pinellia ternata produced is white in color, high in starch and good in shape. It is popular with users and is called West Pinellia ternata. After the wild cultivation of Pinellia ternata in Xihe County was successfully transformed into artificial cultivation, planting Pinellia ternata became one of the main sources for local people to get rid of poverty and become rich and increase economic income.

Cultivation techniques of High yield, good quality and High efficiency of Pinellia ternata
Pinellia ternata is a commonly used valuable traditional Chinese medicine, which mainly depends on the collection of wild resources to provide commodities for a long time. In recent years, due to the changes of environment, climate and resources, the wild resources are gradually exhausted, while the development of artificial cultivation is slow, the market has been in short supply, and the price continues to rise. The price in the winter medicine market was 55 to 65 yuan per kilogram in 2005 and 45 yuan per kilogram in the same period in 2004. With the traditional method, the yield of fresh tuber per mu of Pinellia ternata is 500 kg to 750 kg, the drying rate is 25% to 30%, and the yield is 125 mu.
