Where can coffee trees be planted in China-the types and origin of coffee beans

The planting time is from June to July after the beginning of the rainy season. If the planting day is cloudy or light rainy, it can be planted all day. If the planting day is sunny, it should be planted before 11:00 and after 04:30 in the afternoon. Seedlings should choose 5 pairs of true leaves, with a height of more than 0.15 meters, and strong seedlings without branches. The row spacing of planting plants is 1 meter × 2 meters, and 333 plants are planted per mu. After cutting off the bottom 0.03 meters, the seedlings are stripped of the nutrition bag and put into the hole. The nutrient soil is highly consistent with the surface of the platform. The fine soil is layered backfilled after the seedlings are righted, and then gently compacted after covering the soil, so that the nutrient lump can be effectively combined with the surrounding soil. After the coffee is planted, the platform should be fully trimmed to keep the table clean, flat and introverted. After 10 days of planting, the cavities, dead seedlings and damaged seedlings are found and replaced in time to achieve the whole seedling.

Coffee tree opposite leaves are long oval, smooth leaves, the end of the branch is very long, few branches, and the flowers are white, open at the base of the petiole connecting the branch. The ripe coffee berries look like cherries and are bright red with sweet flesh and contain a pair of seeds, namely coffee beans (Coffee Beans). Coffee varieties can be divided into small-grain, medium-grain and large-grain species, the former contains low caffeine content and strong flavor, while the latter two have high caffeine content but poor flavor.

At present, coffee sold in the world is generally made of small and medium seeds in different proportions, usually 70% of medium seeds, mainly caffeine, and 30% of small seeds, mainly for their aroma. Each coffee variety generally has a few to a dozen variants. Coffee is more resistant to shade and cold, but not resistant to light, drought and disease. Coffee contains nine kinds of nutrients, such as caffeine, protein, crude fat, crude fiber and sucrose. As a beverage, coffee is not only mellow and delicious, slightly bitter and sweet, but also can excite nerves and dispel fatigue.

The origin of the coffee tree is 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 the seeds of the fruit of coffee trees, just because they are shaped like beans, so they are called coffee 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 the most suitable for growing coffee. This coffee production zone is generally referred to as "coffee belt" or "coffee area".
