Brief introduction of Coffee planting in Huaguoshan Coffee, Yunnan Province, Geographic location, Climate and altitude

Due to the lack of deep processing and marketing, Yunnan coffee is not well-known and unrecognized by people locked in the mountains. It is believed that with the in-depth development of Yunnan coffee industry, the rising demand of domestic coffee market and the efforts of the government and enterprises, Yunnan coffee will usher in a new period of development.

The western and southern parts of Yunnan Province are located between 15 °N and the Tropic of Cancer, and most areas are 1000-2000 meters above sea level. The topography is dominated by mountains and slopes, with large ups and downs, fertile soil, sufficient sunshine, rich rainfall and large temperature difference between day and night. These unique natural conditions form the particularity of Yunnan small grain coffee taste-strong but not bitter, fragrant but not strong, slightly fruity. As early as the 1950s, Yunnan small seed coffee was very popular in the international coffee market and was rated as the top grade of coffee.

The history of coffee cultivation in Yunnan can be traced back to 1892. A French missionary brought coffee to Yunnan from abroad and successfully planted it in a valley in Binchuan County, Yunnan Province. The coffee plants of this batch of coffee seeds are still blooming and bearing fruit in Binchuan County.

Yunnan coffee was planted on a large scale in the mid-1950s, with a planting scale of 4000 hectares at one time. By the end of 1997, the planting area of coffee in the province had reached 7800 hectares. At present, the planting area of the province accounts for 70% of the national area, and the output accounts for 83% of the whole country. Yunnan coffee has established the dominant position in China in terms of planting area and coffee bean production.

The quality of coffee depends on many factors, such as growing environment, climate, cultivation and management techniques and so on. Its best growing environment is low latitude, high altitude, sufficient rainfall and suitable sunshine, so the north latitude is 15. The ideal growing area for coffee is between the Tropic of Cancer and the Tropic of Cancer. However, other areas in this zone, such as Hawaii and Saudi Arabia in the United States, or low altitude or little rain in the desert, are not conducive to coffee growth, only southern Yunnan in this zone happens to have all kinds of conditions. According to the determination of experts, small seed coffee should be planted in the mountains at an altitude of 800 to 1800 meters. If the altitude is too high, it will taste sour, and if it is too low, it will taste bitter. Yunnan coffee is mostly planted in dry and hot valleys at an altitude of 1100 meters above sea level, so it has a moderate sour taste, rich and mellow aroma. In terms of climatic conditions, the long light time in southern Yunnan is conducive to plant growth and photosynthesis, and the large temperature difference between day and night and low temperature at night are conducive to the accumulation of coffee nutrients. Therefore, the effective nutrients of Yunnan small-grain coffee are higher than those of other foreign coffee varieties. Small seed coffee is easy to be infected with rust, and the yield and quality of embroidery disease are deeply affected. In the hot area of Yunnan, due to the distinct dry and wet, the red ripening of fresh fruit enters the dry season every year, and the relative humidity is low, which is not conducive to the formation and growth of rust blister. Due to the excellent quality of Yunnan coffee, it entered the London market with "Lujiang No.1" in the 1960s and was rated as first-class. In recent years, the world-famous coffee companies such as Nestle and McDonnell have come to Yunnan to open up raw material bases, and the products produced in Yunnan are also gradually famous at home and abroad. At present, the average yield of coffee in Yunnan has reached 96.4 kg, and a household contracted land in Lujiang has set a world record of 400 kg. "I have seen countless coffee plantations in the world, where the management is world-class and the yield is the highest," said Steyhead, a chief coffee expert at the United Nations Planning and Development Program, after visiting the coffee garden at Lujiang Farm.

Yunnan coffee is a variant of Arabian original species, which has been cultivated for more than one hundred years after long-term cultivation and domestication. Due to the unique geographical environment and climatic conditions, Yunnan coffee has formed a unique flavor of strong but not bitter, fragrant but not strong, with a little fruit flavor. World-class coffee experts evaluate it as the best coffee in the world, and its cultivation techniques. The yield per unit area is also world-class. The quality of coffee depends on many factors, such as growing environment, climate, cultivation and management techniques and so on. Its best growing environment is low latitude, high altitude, sufficient rainfall and suitable sunshine, so the north latitude is 15. The ideal growing area for coffee is between the Tropic of Cancer and the Tropic of Cancer. However, other areas in this zone, such as Hawaii and Saudi Arabia in the United States, or low altitude or little rain in the desert, are not conducive to coffee growth, only southern Yunnan in this zone happens to have all kinds of conditions. According to the determination of experts, small seed coffee should be planted in the mountains at an altitude of 800 to 1800 meters. If the altitude is too high, it will taste sour, and if it is too low, it will taste bitter. The planted land needs a certain slope, otherwise the quality of the coffee is slightly worse, and there are many diseases.

Coffee cultivation in China is concentrated in Yunnan and Hainan provinces. Yunnan has a large output, with an annual output of about 26000 tons in recent years, accounting for 90 per cent of the national output. It is said that Yunnan coffee came from the French 70 or 80 years ago. The main variety is Arabica Arabica, that is, the so-called small seed coffee, commonly known as Yunnan small grain coffee. Yunnan's high-quality geographical and climatic conditions provide good conditions for coffee growth. The planting areas are Lincang, Baoshan, Simao, Xishuangbanna, Dehong and other prefectures. The natural conditions of Yunnan are very similar to those of Colombia, that is, low latitude, high altitude and large temperature difference between day and night. The small grain coffee produced is mellow by cup quality analysis, and its quality and taste is similar to that of Colombian coffee.

However, due to a variety of reasons, the development of Yunnan coffee industry is not fast. Yunnan coffee is mainly exported as raw materials, with an export volume of about 15000 tons in 2006. More than 60% of raw materials are acquired by Nestl é and Maxwell each year, and Starbucks and Amway have joined in recent years.
