Geographical distribution of coffee bean producing areas and planting techniques of coffee trees

Geographical distribution editing

Coffee grows mostly in countries with alpine terrain between the Tropic of Cancer and the Tropic of Cancer. It is native to tropical Africa and is introduced and cultivated in South and Southwest China. [2]

The origin of coffee tree [4] is in Ethiopia in Africa. In botany, coffee trees belong to the evergreen trees of the subgenus Rubiaceae, and coffee beans, commonly known as coffee beans, are actually the seeds of the fruit of coffee trees. They are called coffee beans only because they are shaped like beans. Climate is the decisive factor for coffee cultivation. Coffee trees are only suitable for growing in the tropics or subtropics, so the zone between latitude 25 degrees south and north is generally called coffee belt or coffee area. However, not all the land located in this area can produce good coffee trees.

Conditions

The ideal planting conditions for coffee trees are as follows: the temperature is between 15 and 25 ℃, and

The annual rainfall must reach 1500 to 2000 mm, and the rainfall time should be in line with the flowering cycle of the coffee tree. Of course, in addition to the seasonal rainfall, there should also be fertile soil and good drainage. Fertile soil containing volcanic ash, in addition, although sunlight is an indispensable element for the growth and fruit of coffee, too strong sunlight will inhibit the growth of coffee trees, so various producing areas usually cooperate with the planting of some shade trees. The ideal altitude is 500 to 2000 meters above sea level. [2]

It can be seen that the conditions for cultivating high-quality coffee are very strict: sunlight, rainfall, soil, air temperature, as well as the way coffee beans are harvested and the process of making coffee beans will affect the quality of coffee itself.
