The planting technology of coffee requirements for planting coffee trees

Coffee fruit contains two seeds, namely coffee beans. The two beans are connected face to face with each other on one side of the plane. Each coffee bean has a thin outer film, which is called silver skin, and its outer layer is covered with a yellow outer skin, called endocarp. The whole coffee bean is wrapped in a sticky pulp to form the coffee pulp, which is soft and sweet, with the outer shell. [1]

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. So 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. [2]
