Tea tree is a shrub or small tree of Theaceae and Camellia, with hairless shoots. Leaves leathery, oblong or oval, Tea leaves can be used to make tea (different from camellia oleifera), seeds can be used to extract oil, tea trees are fine in material, and their wood can be used for carving.

The distribution is mainly between 16 degrees south latitude and 30 degrees north latitude. Tea trees like warm and humid climate. When the average temperature is above 10℃, the buds begin to sprout, and the optimum temperature for growth is 20 ~ 25℃. The annual precipitation should be above 1000 mm;

Southwest China is the origin center of tea trees, and tea trees have been introduced to 60 countries in the world. In tropical areas, there are also arbor-type tea trees as high as15-30m, with a base girth of1.5m or more, and the tree age can reach hundreds to thousands of years.

Extended data:

The propagation of tea trees mostly adopts the method of cultivating seedlings with roots. In the past, the layering method was rarely used because of its slow propagation speed.

Temperature is the basic condition of tea life activities. It affects the geographical distribution of tea trees and restricts the growth rate of tea trees. The influence of temperature on tea trees mainly shows two aspects: air temperature and soil temperature.

Air temperature mainly affects the growth of aerial parts, and ground temperature mainly affects the growth of roots. But air temperature and ground temperature are interrelated. As far as temperature is concerned, tea trees can be widely adapted from tropical to temperate zones. But as for growth, there are three basic points of temperature, namely, the starting point temperature, the suitable temperature and the low limit temperature of tea tree growth.
