Growth environment of yam

Dioscorea opposita, also known as Dioscorea opposita, grows on hillsides and valleys at an altitude of150-1500m, in thickets or weeds beside streams and roadsides. Dioscorea is a short-day and warm-loving crop. Optimum temperature for seedling growth 15-20℃. The optimum growth temperature is 25-28℃, and the growth is slow below 20℃.

Dioscorea opposita is suitable to grow in loose, fertile and deep soil, but flat species and block species can also grow in shallow and sticky soil. Dioscorea opposita is drought-tolerant, but not waterlogging-tolerant, so it is not suitable for planting in soil with too shallow or too humid groundwater level, and the water content of sandy soil and loam soil is about 18%.

Dioscorea is distributed in Korea, Japan and China. In China, it is distributed in Henan, south of Huaihe River in Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian, Taiwan Province, Hubei, Hunan, Guangdong (Niutou Mountain in Zhongshan), Guizhou, northern Yunnan (Gongshan, Deqin and Lijiang), Sichuan, eastern Gansu and southwestern Shaanxi (350-1500m).
