Introduction to the requirements of natural conditions in the growth process of wild coffee

In fact, the Arabs began to grow coffee in 525 BC, and chewing fried coffee beans became popular in the Arab region. In 890 AD, Arab merchants sold coffee beans to Yemen, and Yemenis made coffee beans into drinks for the first time. In the 15th century, coffee was introduced into Europe, Asia and soon into America. By the 18th century, coffee was widely grown in tropical and subtropical regions of the world and became one of the three major drinks in the world. Coffee ranks first among the top three beverages in annual sales, three times as much as cocoa and four times as much as tea. Although coffee has been cultivated in the world for more than 2000 years. However, coffee has been cultivated in China for only a few hundred years. In 1884, Taiwan Province began to introduce coffee.

At the beginning of the 20th century, overseas Chinese brought coffee back from Malaysia to grow in Hainan Province. Later, tropical and subtropical provinces in the south began to grow plant coffee one after another. Although the cultivation time is short, the coffee from Hainan and Yunnan provinces in China has excellent quality and unique charm, so it enjoys a high reputation in the world. After some foreign businessmen buy it at a low price, it is processed and sold to the international market. It has become an expensive world-class drink, especially the small-grain coffee grown in Yunnan Province. Because of the large temperature difference between day and night in Yunnan, it is conducive to the accumulation of substances in it. Therefore, it tastes strong but not bitter, fragrant but not strong, oily and fruity, so it is praised as "the best quality coffee in the world" by coffee merchants at home and abroad.

Another legend is that one day in 500 BC, an Ethiopian shepherd herded his sheep to a strange place for grazing. On a small hill, the sheep ate a kind of small red fruit on a small tree. after returning in the evening, the sheep were unusual in the fence, not as peaceful and docile as usual, but excited, restless, tearing and shouting, and even jumping all night long. The owner thought that the sheep had been poisoned by eating some grass and got up several times to take a closer look at the lights, but they saw the sheep in high spirits and alive. It doesn't look like poisoning pain.

Linnemas, a Swedish botanist in the 18th century, described this genus, but botanists disagreed on its precise classification. There may be at least 25 major varieties of coffee, all of which are native to tropical Africa and some islands in the Indian Ocean. However, due to the varieties of trees and seeds, they are also different. All kinds of coffea are woody plants, but they may be low shrubs or trees higher than 10 meters, and the leaves vary in color from light yellow to purple.

Coffee will probably be seeded in 3-4 years, and the yield will decrease after 20-25 years, but some coffee trees still bear fruit beyond 100 years of life. The branches of coffee trees grow opposite and grow horizontally or drooping branches, while their leaves grow on short-diameter branches. The two main species are Arabica (CoffeeArabic) and CoffeeRobusta. The leaves of Arabica are about 15 centimeters long. Robbins' leaves are long, soft-oval or pointed in shape and bright green in color.
