Types of coffee trees, classification and characteristics of coffee tree varieties, what are the typ

At present, the most important coffee beans in the world are mainly from Arabica, Robasda and Liberia, these three varieties of coffee beans are the three original varieties of coffee trees, and the quality of coffee beans produced is also the highest in the quality of coffee beans produced by other coffee trees.

Arabica coffee trees of Ethiopia origin, the yield of coffee beans.

70o% of the world's production; The world-famous Blue Mountain Gaphine, Mocha Coffee, etc., are almost all Arabica. Arabica coffee trees are suitable for planting in high mountains with large temperature differences between day and night, as well as ten soils with low humidity and good drainage; The ideal altitude is 500 meters above sea level, and the higher the altitude, the better the quality. However, due to the weaker ability to resist pests and diseases, it is better than the other two.

Coffee trees are difficult to grow.

The Robasta coffee tree is native to the Congo in Africa, where it accounts for about 20 30 percent of the world's production. The Roba Jinta coffee tree is suitable for planting in lowlands below 500 meters above sea level, and has strong adaptability to the external environment, can resist harsh climate, resist pests and diseases, and prepare the land. It doesn't take much for weeding and pruning.

It is a coffee tree that can be left to grow in the wild and can be easily cultivated. However, its flavor is bitter and inferior to that of Arabica, so it is mostly used to make instant coffee. In general, the coffee sold in fast food stores is mainly made from Robusta coffee beans.

Since it is produced in Africa, most Africans drink Robusta coffee.

Liberian coffee trees are produced in Liberia, Africa, and its cultivation history is shorter than that of the other two coffee trees, so it is only planted in a few places such as Liberia, Suriname, and Gaiana, so it accounts for less than 5% of the world's production. The Liberbiwanga coffee tree is suitable for planting in the lowlands, and the coffee beans produced have a strong aroma and bitter taste.

There are more than 500 species of coffee trees, and there are 6,000 varieties, most of which are tropical trees and shrubs. There are four major coffee trees in the world, and only two are truly commercially valuable and are planted in large quantities, and the quality of coffee beans produced is also higher than that of other coffee trees.

The main species of coffee tree: Liberian species.

The Liberian species, or large-grained species, is native to Liberia, Africa, and a few countries such as Malaysia. It has a slightly shorter cultivation history than the other two coffee trees, and the Liberian coffee tree is suitable for lowland cultivation, with a tall, strong trunk that is 18 meters tall, with large, tough leaves, and large fruits and beans.

The main species of coffee tree: Ethelsa species.

The Ethelsa variety was discovered only in 1904 and is native to the Charles River valley in Africa, with small fruit and high yield per plant, especially a drought-resistant variety. The product has a strong flavor and a slightly bitter taste, and is less cultivated.

The main species of coffee tree: Arabica species.

The bean is smaller, the front is oblong, the middle crack is narrow and tortuous, and the back of the bean is rounded and flat.

The main species of coffee tree: Robasta species.

The bean shape is larger, the front is gradually rounded, the back is round and convex, and the crack is straight.

Coffee trees are mainly divided into two kinds, one is Arabica coffee tree, the other is Robusta coffee tree, Arabica yield is very high, has been in the first place, its total coffee production accounts for about 60-70% of all coffee, coffee trees grow at a relatively high altitude, or volcanoes, limestone, granite soil, it grows where the temperature difference between day and night is very large, dry and wet seasons are more obvious, at the same time, it likes more fertile soil.

The coffee tree is now widely cultivated and is native to the tropical regions of northern and central Africa. Coffee trees grow at high altitudes, or on volcanic, limestone, granite soils.

The temperature difference between day and night is very large in the place where it grows, and it is also obvious in the dry and wet seasons. At the same time, it prefers more fertile soil. In addition, coffee trees are not hardy, generally speaking, around 20 degrees Celsius is the most suitable temperature for coffee trees to grow.

Coffee tree variety.

There are two main types of coffee trees, one is Arabica coffee tree, and the other is the Robusta coffee tree, and the yield of Arabica is very high. At present, it has been in the first place, accounting for about 60-70% of all coffee, while Robusta coffee accounts for about 30-40% of the world's total coffee production.

1.Arabica

Arabica is a relatively small-grained coffee bean, it is produced in the Ethiopian region, this coffee tree grows at an altitude of about 1000-2000 meters above sea level, and is a very hardy tree.

The optimal temperature for its growth is around 15-24, and this coffee tree requires a lot of humidity. In addition, its leaf shape is oval, the color is dark green, its fruit is also oval, and its caffeine content is about around the same level.

2.Robusta

Robusta is a medium-grain coffee that is produced in the Congo of Africa, and the Robusta coffee tree generally grows at an altitude of about 200-800 meters. It prefers a warm growing environment, and its temperature requirements are around 24-29. It takes about 9-11 months from pollination to fruiting, and the growth cycle is relatively long.

The coffee tree has many branches at the base, its young branches are smooth, its old branches are mostly grayish-white, its leaves are thin and leathery, it will bear fruit at a certain time, and its fruit will fall off easily. Coffee trees are suitable for growing in a warm, moist and shaded environment, and are not tolerant to strong light, so they should be shaded when planting.

Many people don't know what the coffee tree looks like, the coffee tree is also known as small grain coffee, Dutch coffee tree, its plant can grow up to 8 meters, it has many branches at the base, and its young branches are smooth. The old branches of the coffee tree are mostly grayish-white, its leaves are thin and leathery, and its leaves are ovate-lanceolate or lanceolate.

The leaves of the coffee tree can grow up to 14cm up to 14cm and up to 5cm at the widest, it will bear fruit at a certain time, its fruit is easy to fall off the tree when ripe, its fruit is red in color and very small. Coffee trees are highly hardy and can grow in low temperatures for a short period of time in winter without freezing to death.

Coffee trees are native to tropical rainforests, suitable for growing in warm, humid and shady environments, mostly growing in mountains at an altitude of 800 to 1800m, and are mostly planted in tropical areas. The branches of the coffee tree are fragile and do not tolerate strong winds, so it is best to plant the plants in a sheltered environment and protect them during strong winds.

Coffee trees are not tolerant to strong light, so do a good job of shading when planting to prevent the plants from being sunburned by strong light, and water and fertilize the plants in time when planting coffee trees, otherwise it will affect the normal growth of the plants. Coffee trees grow at a fast rate, so you should prune the branches regularly when planting, and you can use the light pruning method for each pruning.
