2. Temperature: Amomum villosum likes high temperature environment, and the suitable growth temperature is between 22-28 degrees, and the temperature is between 15- 19 degrees, so it grows slowly and can tolerate the low temperature of 1-3 degrees for a short time, and it does not bloom or scatter powder below 17 degrees.

3. Humidity: Amomum villosum likes humid environment, which requires annual precipitation above 65,438 000 mm, air humidity above 80%, soil temperature at different growth stages, air humidity above 90% during flowering and pollination, and soil water content above 24%-26%.

4. Distribution: Amomum villosum can't accept strong light and is suitable for treating astigmatism. Amomum villosum is mainly distributed in Fujian, Guangdong, Guangxi, Yunnan and other places in China, and is cultivated or wild in shady and humid places in mountainous areas.
