What is the distribution of Pinellia ternata?

Pinellia ternata, also known as Diwen, Shoutian, etc., is a perennial herb of Araceae, widely distributed in the Yangtze River Basin and Northeast and North China in China. It is also distributed in Xizang, about 3000m above sea level. The following editor will introduce the distribution of Pinellia ternata.

Distribution of producing area of Pinellia ternata

Pinellia ternata is mainly distributed in Hubei, Henan, Anhui, Shandong, Sichuan, Gansu, Zhejiang, Hunan, Hubei, Jiangsu, Hebei, Jiangxi, Shaanxi, Shanxi, Fujian, Guangxi, Guizhou and Yunnan.

Pinellia ternata is mainly produced in Wuchang, Laohekou, Xiangyang, Yangxin and Tianmen in Hubei; Runan, Lingbao, Lushi, Yuanchi, Xixian, Huaibin and Tanghe in Henan; Huaining, Xuancheng, Ningguo, Funan, Yingshang in Anhui; Jinxiang, Juye, Jiaonan, Wulian and Laiyang in Shandong; Suining, Anyue, Wanxian, Zhaojue, Yuechi, Bishan, Longchang, Rongchang, Zhongxian and Yingshan in Sichuan.

Ecological environment of Pinellia ternata

1. Temperature: when the average ground temperature is about 10 ℃, Pinellia ternata germinates and seedlings emerge, and when the average temperature reaches 15 ℃ ~ 27 ℃, Pinellia ternata grows the most. In some parts of China, since mid-July, with the end of the plum rain season, the temperature rises, and the highest temperature often exceeds 35 ℃. The growth of Pinellia ternata is seriously affected, and the aboveground parts of Pinellia ternata without shade die one after another, forming summer seedlings. The suitable temperature for Pinellia ternata growth is 23 ℃ ~ 29 ℃.

2. Humidity: Pinellia ternata is not tolerant to drought and likes to grow in the soil with high humidity. We have investigated a high yield field of Pinellia ternata in Zhongxing Town, Shan County, with an average tuber yield of 1500 kg. Its variety is "narrow clover Pinellia ternata" in Heze, there is almost no obvious seedling falling process in the whole year, and the growth is very exuberant even in the midsummer season. One of the main measures is to irrigation with well water ditch once every evening in summer, which not only keeps the soil moist, but also lowers the soil temperature, killing two birds with one stone. Pinellia ternata both like and afraid of water, when the soil moisture exceeds a certain limit, but poor growth, resulting in rotten root, rotten stem, seedling death, tuber yield decreased.

3. Light: Pinellia ternata is a shade-tolerant rather than shade-loving plant, which can grow luxuriantly under moderate shading conditions. However, if the light is too strong, Pinellia ternata is difficult to survive. The number of bulbs and the weight gain of tubers can reach the maximum in semi-shade environment.

Legend of the origin of Pinellia ternata

It is said that a long time ago, there was a girl named Bai Xia. When she was mowing grass in the field, she dug up the underground tuber of a plant. Because she was so hungry, she tried to put the tuber in her mouth and chew it to fill her stomach. Who knew that after eating, she threw up, she quickly chewed a piece of ginger to stop vomiting, vomiting stopped, who knows even the long-lasting cough has been cured. So Bai Xia used this medicine and ginger to cook soup for the villagers to treat cough, and the effect was very good. But this plant tuber is rich in serous and needs to be washed many times before it can be used. One day, when Bai Xia was washing the medicine by the river, she accidentally slipped into the river and died. In memory of her, the local people named this medicine "Baixia". Later, people found that Bai Xia was harvested in summer and autumn, and with the passage of time, he gradually changed "Baixia" to "Pinellia".
