3. Morphological types of tea fruits: red ball, green ball, navel red peach, green peach, red peach and green orange. Camellia oleifera and other woody oils need to be developed on a large scale. The oil in rice, oil, salt, sauce and vinegar tea is essential for people to have three meals a day. However, due to the small population in China, it is difficult to take out more land to grow herbal oil. A better solution is to develop woody edible oil.

At present, most plant edible oils in China are provided by herbal oils such as rapeseed, peanut, sesame and soybean, and woody oils account for a small proportion. With the gradual improvement of living standards, people have higher and higher requirements for plant edible oil. Because China has a large population and little land, it is difficult to grow more land to grow herbs and medicinal oil. Professor He Fang, doctoral supervisor of Economic Forestry Research Institute of Central South Forestry University, believes that developing woody edible oil is the best way to solve the shortage of edible oil supply and low quality.

Woody oil: planted and harvested for many years.

Woody oil refers to the oil produced by woody plants, such as tea oil and tung oil. Corresponding to this is herbal oil, such as vegetable oil and soybean oil. Woody oils are usually divided into three categories according to their uses: first, woody edible oils, such as tea oil. The second is woody industrial oil, such as tung oil. The third is woody aromatic oil, such as litsea cubeba oil.

Woody edible oil has a long history and rich resources. In the early days of mankind, the earliest edible vegetable oil was directly picked from trees and squeezed from mature oil-bearing seeds. Later, in order to obtain a stable oil source, human beings began to consciously protect woody edible oil tree species, making them one of the earliest economic tree species managed artificially. There are 1 1 woody edible vegetable oils in the world, with an annual output of about 60 million tons, of which palm oil, coconut oil, olive oil and tea oil account for about 30% of the oil production. At present, there are nearly 10 species of woody edible oil cultivated trees in China, such as Camellia oleifera, Olive, Xanthoceras sorbifolia Bunge, Pistacia chinensis Bunge, Acer truncatum Bunge, Butterfly Fruit, Hunan Carya cathayensis, Walnut, Coconut and Malania oleifera Bunge. Among them, the cultivation area of Camellia oleifera in southern 15 provinces (autonomous regions and municipalities) exceeds 60 million mu, which is the largest cultivation area of single tree species among all plantations in China at present. Xanthoceras sorbifolia Bunge is a woody edible oil tree widely distributed in the "Three North" areas of China, with an existing cultivation area of about 500,000 mu. Olive, called Qidun Fruit in ancient times, originated in the coastal area of China. Introduced to China in the Tang Dynasty, there are about 600,000 strains now. The main planting areas are Sichuan, Chongqing, Hubei, Shaanxi, Yunnan and other places.
