Coffee cannot be grown in Lichuan, Hubei Province, China. Coffee trees cannot be grown in any environment, because they are originally plants that grow in tropical rainforest environments. During their system development, they have developed habits that require quiet wind, coolness, shade or semi-shade, and a humid environment. Therefore, people are accustomed to calling the strip area suitable for the growth of coffee trees between 25° north and south latitude on both sides of the equator as the coffee belt. Most of the happy places where coffee grows are countries with high mountain terrain between the Tropic of Cancer and the Tropic of Cancer. Coffee is mainly produced in tropical Africa, and has been introduced and cultivated in South China and Southwest China.

[Morphological characteristics]: The origin of coffee trees is Ethiopia in Africa. Botanically, the coffee tree belongs to the Rubiaceae family and is an evergreen tree of the subgenus Coffea. The commonly known coffee beans are actually the seeds of the coffee tree. They are called coffee beans because they are shaped like beans. Climate is the decisive factor in coffee cultivation. Coffee trees are only suitable for growing in the tropics or subtropics, between 25° north and south latitude, generally called the coffee belt or coffee zone. However, not all areas located in this area can grow excellent coffee trees.

[Temperature]: The temperature requirements of coffee generally vary with the cultivation species. Small-grain coffee is more cold-resistant and likes a warm and cool climate, requiring an average annual temperature of 19~21℃.

[Growing conditions]: The most ideal planting conditions for coffee trees are: a climate with a temperature between 15 and 25 degrees Celsius, and annual rainfall of 1500 to 2000 mm. At the same time, the rainfall time is It must be able to match the flowering cycle of the coffee tree. Of course, in addition to the coordination of seasonal rainfall, there must be fertile soil and good drainage. Fertile soil containing volcanic ash. In addition, although sunlight is an indispensable factor for the growth and fruiting of coffee, too strong sunlight will inhibit the growth of coffee trees, so each producing area usually plants some shade trees. The ideal altitude is 500~2000 meters. It can be seen that the conditions for cultivating high-quality coffee are quite strict: sunlight, rainfall, soil, temperature, as well as the way of harvesting coffee beans and the production process will all affect the quality of the coffee itself. This greatly limits its suitable range.
