Introduction to the planting Climate of Coffee in Yunnan, China

At present, Yunnan coffee production is mainly distributed in Pu'er (180000 mu), Baoshan (100000 mu), Dehong (120000 mu) and Lincang (20 mu). Most of them are catimor varieties. At present, more than 80% of them are used as raw materials for instant coffee processing, some are supplied to Nestl é, and some are exported to Europe and the United States by local traders. According to the grading standard of specialty coffee, the quality of Yunnan coffee is far from good enough.

From the perspective of geographical and climatic environment, Yunnan has a vast area of land is more suitable for growing coffee.

Climate of Pu'er City:

The climate of Pu'er City has three characteristics: low latitude, monsoon and vertical climate. Geographically, the south is close to the Indian Ocean and the Bay of Bengal, affected by the humid Indian Ocean monsoon, the towering Ailao Mountains and Wuliang Mountains in the east block the invasion of the cold current in Siberia, forming the main climatic characteristics of warm, humid and calm wind. The temperature difference between the coldest month and the hottest month is not obvious, so it is a real "spring-like" area. The annual average temperature is 15.3-20.2 ℃, the annual precipitation is 1000-2780mm, and the annual sunshine hours is 1873.9-2206.3 hours / year.

The vertical height difference makes the vertical three-dimensional climate obvious, from low to high, there are many climate types, such as north subtropics, south temperate zone, temperate zone and so on. On the other hand, coffee cultivation is mainly distributed in the mountainous areas with an elevation of 800,000m above sea level.

Three-dimensional climate is particularly obvious, there are "a mountain is divided into four seasons, ten miles of different days," said, rainy summer, winter drought, sunny and rainy day and night. The annual average temperature of Lujiangba, the main area of coffee cultivation in Longyang District.

21.3 ℃, mean maximum temperature 29.0 ℃, mean minimum temperature 15.5 ℃, extreme maximum temperature 40.3 ℃, extreme daily minimum temperature 0.2 ℃, annual precipitation 747.6 mm, annual sunshine hours 2318.1 hours, annual ≥ 10 ℃ active accumulated temperature 7800.0 ℃, annual frost-free days average 357 days.
