As early as 100 years before the Gongyuan, China began to plant the tea-oil trees, which have been in the past for over 2000 years. The camellia oleifera seed cultivation method grows in natural pollution-free mountains and hilly lands in subtropical humid climate areas in south China, more than 10 provinces can be planted, the main production areas are in provinces and cities (regions) in Hunan, Jiangxi, Guangxi, Chongqing and the like in China, the existing cultivation area in China is about 4500 ten thousand mu, 100 ten thousand tons of camellia oleifera seeds are produced annually, and 27 thousand tons of camellia oleifera seed oil are produced. The camellia oleifera is suitable for production at the best pH value of 5-6.5 in acid soil, the annual average temperature is 14-21 ℃, and the annual rainfall is 800-2000 mm. The frost-free period is 200-fold year 360 days, the altitude is below 300m, the extreme low temperature reaches-17 ℃ and is more than or equal to 10 ℃, and the accumulated temperature is 4250-fold year 7000 ℃.
The camellia oleifera is evergreen in four seasons, developed in root system, drought-resistant and barren, resistant to low-temperature freezing damage, good in fire prevention effect, wide in growth range, capable of fully utilizing marginal land to develop, capable of promoting rural economic development, greening barren mountains, maintaining water and soil and promoting vegetation recovery in ecological fragile areas, has ecological functions of beautifying environment, maintaining water and soil and adjusting climate, is a tree species with strong anti-pollution capacity, and is strong in sulfur dioxide resistance and hydrogen and chlorine absorption capacity.
The camellia oleifera seeds can germinate without obvious dormancy period or after being sowed at intervals, and the common camellia oleifera seeds can be stored for about 2 years at room temperature. In the prior art, in order to improve the germination rate of seeds, the seeds are wrapped in gauze and soaked for one day before sowing, then the seeds are put into a refrigerator and treated for 15 days at low temperature of 0-3 ℃, and finally the seeds are sowed. However, the method is long in time consumption and has certain limitations.
