1. Camellia oleifera likes warmth and is afraid of cold. The annual average temperature 16 ~ 18℃ and the flowering average temperature 12 ~ 13℃ are required. Sudden low temperature or late frost will cause falling flowers and fruits. Sufficient sunshine is needed, otherwise only branches and leaves will grow, resulting in less results and low oil content. Sufficient moisture is needed, and the annual precipitation is generally above 1000 mm, but continuous rainfall at flowering stage affects pollination. It is required to plant in a place with gentle slope and weak erosion, and the requirements for soil are not strict. Generally, it is suitable for acid soil with deep soil layer, not for places with many stones and hard soil.

2. Camellia oleifera is one of the four major woody oil plants in the world. It grows in the mountains and hills in the subtropical region of southern China and is a kind of pure natural high-grade oil plant unique to China. Mainly concentrated in Zhejiang, Jiangxi, Henan, Hunan and Guangxi provinces, the national annual output is only about 200,000 tons.
