Coffee tree cultivation conditions

Coffee tree is a kind of horticultural perennial cash crop. it is a perennial evergreen shrub or small tree of Rubiaceae, which has the characteristics of fast growth, high yield, high value and wide market. the growing paradise is mostly located in countries with alpine topography between the Tropic of Cancer and tropical Africa, and is introduced and cultivated in South and Southwest China. Let's take a look at the planting conditions of coffee trees.

Growth habits of coffee trees

Coffee trees like mild temperatures during the day and less than two hours of direct sunshine, so if there is no afternoon shower or fog to report every day, local farmers have to plant many taller trees in the coffee garden for shade. At night, they want an environment of about 10 degrees Celsius but the temperature is not too low, because too warm will make the coffee berries grow too fast. Can not produce small and strong hard high-quality coffee beans, in case it is too cold to frost, it will freeze to death.

Planting conditions of coffee trees

The ideal planting conditions for coffee trees are the temperature between 15 and 25 ℃ and the annual rainfall of 1500mm to 2000mm, and the rainfall time should be in line with the flowering cycle of coffee trees. Of course, in addition to the seasonal rainfall, it is also necessary to drain well the 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 will usually cooperate with the planting of some shade trees. The ideal altitude is 500 to 2000 meters above sea level. It can be seen that the conditions for the cultivation of high-quality coffee are very strict. Sunlight, rainfall, soil, air temperature and the way coffee beans are harvested and the production process will affect the quality of coffee itself.

History of Coffee planting

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.

Coffee has been cultivated in China for only a few hundred years. Taiwan Province began to introduce coffee in 1884. At the beginning of the 20th century, overseas Chinese brought coffee back from Malaysia to be planted in Hainan Province. Later, tropical and subtropical provinces in the south began to grow plant coffee. 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.
