Cinnamomum cassia in China, Yugui, belongs to Cinnamomum cassia of Lauraceae. Cinnamon is its scientific name, also called osmanthus. It originated in China, Laos, Indian and Vietnamese. The bark is grayish brown, the old bark is thicker, and cinnamon is the old bark. After peeling from the trunk, after a period of shelving and drying, the overall shape will curl, which is our common dry shape. It is usually used as a condiment.

Cinnamon is native to China and widely cultivated in tropical and subtropical regions of Guangdong, Guangxi, Hainan, Fujian, Taiwan Province, Hunan, Jiangxi, Zhejiang, Yunnan and other provinces, with Guangxi being the most cultivated. Cinnamomum cassia likes warm and humid climate, which requires annual average temperature to be higher than 20℃, extremely short high temperature to be lower than 39℃, extremely short low temperature to be above -5℃, and annual rainfall to be above 1, 200mm. Cinnamomum cassia is suitable for growing on the slightly acidic soil with deep, loose, moist, fertile and good drainage, such as granite, sand shale and conglomerate.

The growing environment of Cinnamomum cassia

Cinnamon enjoys a warm climate and is suitable for growing in a frost-free environment in subtropical areas. The most suitable growth temperature is 26-30℃, and the growth starts when the monthly average temperature is above 20℃, and grows slowly below 20℃, and there is no freezing injury at 0-5℃. Cinnamon likes wet, but avoids stagnant water. It requires abundant rainfall and relative humidity above 70%, but too much rain will cause root rot and leaf rot. In areas that are too dry, the growth potential of plants is poor.

Cinnamon is a semi-negative tree species, and the requirements for light vary with the age of the tree. Seedlings like shade and avoid direct sunlight. Adult trees can grow normally in more sunlight. Cinnamon is a deep-rooted tree species, which requires sandy loam or loam with deep soil layer, loose texture, good drainage and strong permeability. Like slightly acidic or acidic soil, it grows well on red and yellow loam with pH value of 4.5-6.5.
