Colombian coffee fruit with exocarp dura and mesocarp fleshy.

Colombia, located in the northwest of South America, is a beautiful country with a long history. Indians have lived on this land since ancient times. It was colonized by Spain in 1531 and gained independence in 1819. It was renamed in 1886 to commemorate Columbus, the discoverer of the American continent. Colombia has beautiful mountains and rivers, beautiful scenery, pleasant climate, spring all year round and fresh air. Colombia is rich in products, especially coffee, flowers, gold and emeralds are known as the "four treasures". Today, the country is the second largest coffee producer after Brazil, the world's largest exporter of Arabica coffee beans and the world's largest exporter of washed coffee beans. Colombian coffee is often described as silky and smooth. Of all the coffees, it is the most balanced, soft, smooth and ready to drink, and it has won praise that no other coffee can match: known as "green gold".

Plant morphology of Colombian coffee

Plant Morphology of Colombian Coffee (10)

The main varieties of Colombian coffee are small grains of coffee. Plants are small trees or large shrubs, 5-8 m tall, usually much branched at base; old branches gray-white, nodes dilated, young branches glabrous, compressed. Leaves thinly leathery, ovate-lanceolate or lanceolate, 6-14 cm long and 3.5-5 cm wide, apex long acuminate, acuminate part 10-15 mm long, base cuneate or slightly obtuse, rarely rounded, entire or shallowly wavy, both surfaces glabrous, lower vein axils with or without small pores; midrib raised on both surfaces of leaf, 7-13 on each side of lateral veins; petiole 8-15 mm long Stipules broadly triangular, arising from the tip of the upper part of the young branch conical or awn tip, the tip of the old branch is often protruding tip, 3-6 mm long. Cymes several clustered in leaf axils, each with 2-5 flowers, without a total pedicel or with a very short peduncle; flowers fragrant, with pedicels 0.5-1 mm long; bracts base ±connate, dimorphic, 2 broadly triangular, nearly equal in length and width, the other 2 lanceolate, 2 times as long as wide, leaf-shaped; calyx tubular, 2.5-3 mm long, calyx eaves truncate or 5-denticulate. Corolla white, length varies from breed to breed, generally 10-18 mm long, apically often 5-lobed, rarely 4-or 6-lobed, lobes often longer than Corolla tube, tip often obtuse; anthers protruding from Corolla tube, 6-8 mm long; style 12-14 mm long, stigma 2-lobed, 3-4 mm long. Berries broadly elliptic, red, 12-16 mm long, 10-12 mm in diameter, exocarp dura, mesocarp fleshy, sweet at maturity; seeds raised abaxially, ventral flat, longitudinally grooved, 8-10 mm long and 5-7 mm in diam. The florescence is from March to April. [2]

Planting environment editing

The suitable climate in Colombia provides a real "natural pasture" for coffee. Coffee trees in Colombia are mainly cultivated in the Andes, on steep slopes about 1300 meters above sea level, where the annual temperature is about 18 degrees Celsius, annual rainfall is 2000 to 3000 millimeters, latitude 1 °- 11 °15 north, longitude 72 °- 78 °west, the specific range of elevation is more than 2.000 meters. A special combination of factors, latitude, altitude, soil, plant origin of species and varieties of coffee production in Colombia's coffee growing area, rain patterns produced by the climate of the coffee growing area and tropical convergence, changing topography, luminosity, favorable temperature range throughout the year, moderation and Rain Water's distribution And include some common cultural practice areas in the process of selective logging and transformation, including washing and drying. Very suitable for the growth of coffee, mild climate, humid air, and can be harvested regardless of season. This is why Colombian coffee is of high quality. Colombia has three Codiera mountains running north and south, right into the Andes. Coffee is grown along the highlands of these mountains. The mountain steps provide a diverse climate, where the whole year is the harvest season, and different kinds of coffee ripen at different times. And fortunately, unlike Brazil, Colombia doesn't have to worry about frost. About 2.7 billion coffee trees have been documented in Colombia, 66 per cent of which are planted in modern plantations and the rest on small traditional farms.
