Growth habits of Coffee
Coffee trees belong to the evergreen family of Akanaceae. They are tropical plants and are not cold-tolerant. Most of them are planted in areas with elevations of 300,400m, and also in highlands with elevations of 2000-2500 meters. But those who plant on slopes above 1500 meters above sea level have better quality. Coffee trees are most suitable for growing in an environment where the average temperature is about 20 degrees Celsius, annual precipitation is 1500-2000 mm, soil permeability is strong, and sunshine is suitable. Coffee is afraid of Frosts Descent and the cold winter, and must not be planted in the highlands where frost falls. In general, wild coffee trees can grow to about 8 meters. They are planted at home. In order to protect the quality of coffee beans, facilitate management and harvest, the height is cut to 2 meters. Coffee beans begin to bear fruit 3-5 years after sowing, and 5-20 years is the harvest period. A coffee tree can produce about 3-5 kilograms of coffee fruit every year.
The most important coffee beans in the world mainly come from three original varieties: Arabica, Roberta and Liberia.
The Arabica coffee tree, which originated in Ethiopia, accounts for 70% of the world's coffee production, and almost all the world-famous coffee varieties are Arabica species.
Arabica coffee trees are suitable for growing in high mountains with large temperature difference between day and night, as well as soils with low humidity and good drainage. The ideal altitude is 500m-2000 m. The higher the altitude, the better the quality, but because of the weaker ability to resist diseases and insect pests, it is more difficult to grow than the other two kinds of coffee trees.
The Robosta coffee tree, which originated in the Congo in Africa, accounts for about 20% of the world's production. 30%. Robesta coffee tree is suitable for planting in the lowlands below 500 meters above sea level, has strong adaptability to the environment, can resist bad climate, resist diseases and insect pests, and does not need much manual care during soil preparation, weeding and pruning, and can be allowed to grow in the wild. It is a kind of coffee tree that is easy to cultivate. But its style is more bitter than Arabica, and its quality is much lower, so it is mostly used to make instant coffee. Because it is made in Africa, most Africans drink Robosta coffee.
The Liberian coffee tree is native to Liberia in Africa, and its cultivation history is shorter than that of the other two coffee trees, so the planting is limited to a few places such as Liberia, Surinam and Gaiana. As a result, the output accounts for less than 5% of the world's output. Liberian coffee trees are suitable for planting lowlands, and the coffee beans produced are very fragrant and bitter.
