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.
2. Need enough water. The annual precipitation is generally above 65,438+0,000 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.
Extended data:
Camellia oil can be propagated by sowing, cutting or grafting. In order to keep parents' fine traits, cuttings or grafting are often used to raise seedlings, and then planting and afforestation are carried out. The most suitable afforestation season is from beginning of spring to Beijing and Zhejiang, and there is also 10 month. It is most suitable to sow directly in winter.
2. The unsaturated fatty acid content of tea oil is as high as 90%, which is much higher than rapeseed oil, peanut oil and soybean oil. The content of vitamin E in tea oil is twice that of olive oil. Tea shell is also a good edible fungus culture medium. Studies have shown that camellia saponin has antibacterial and antioxidant effects.
