tea processing in Yunnan did not begin after the establishment of China Tea Trade Company (Yunnan) Ltd.
Yunnan is a treasure land of China for developing the tea industry. All the tea-producing areas of the
province are located at elevations from 1,200 to 2,000 meters. The annual mean temperature ranges from
12ï¿½ï¿½C to 23ï¿½ï¿½C, effective annual heat cumulation is between 4,500ï¿½ï¿½C and 7,000ï¿½ï¿½C, and annual rainfall is
1,000-1,900mm. The monsoon season is concentrated in May through October, during which the rainfall
constitutes about 85% of that of the whole year. The monsoon coincides with the hottest months, and
there is a very high value of effective rainfall. In the dry season which starts in November and ends
in April, There are sufficient sunny day. There is adequate sunshine, and the tea trees have a long
growth period. Under normal conditions, the tea-leaf plucking period may last for 8 to 9 months. The
tea-growing areas are generally covered with red, yellow of brick-red soils with the pH value ranging
between 4 to 6. Comparing with other major tea producing countries, the climate of Yunnan is more
suitable for growing tea trees. Therefore, Yunnan has rich varieties of tea trees and excellent tea species.

the average value, and water-soluble substances by 3-5% higher than the average value.
