Carambola origin, varieties and growing environment

Carambola origin, varieties and growing environment

Star fruit is a fruit with a very unique appearance, with many corners, but it is very sweet. It is also the most suitable fruit to eat after tea or wine.

Carambola

Commonly known as Yangtao and Yangmeitao, it is one of the famous Lingnan fruits. Because its cross section looks like a five-pointed star, it is also called "Star Pear" abroad. The peel of the carambola is waxy, smooth and bright, and the flesh is bright yellow, delicate, crisp, sweet and juicy. Carambola contains a variety of signature nutrients and a large amount of volatile components with a fresh fragrance. Eating a few slices of carambola after tea or wine will make you feel refreshed and happy, with a different flavor. It is worth mentioning that carambola is not only nutritious, but also has the effects of diuresis and analgesia, heat removal and detoxification, digestion and hangover, and blood pressure reduction and comfort.

There are two main types of carambolas: sour carambolas and sweet carambolas. Sour carambolas are large and sour, commonly known as "Sanren", and are rarely eaten raw. They are mostly used as cooking ingredients or processed into candied fruit. Sweet carambolas are excellent in taste, with a sweet taste and no residue.

Origin

Carambola is native to Malaysia and was introduced to my country for cultivation in the Han Dynasty. Currently, carambola is produced and cultivated in Malaysia, Singapore, Thailand and other Southeast Asian countries, and is exported to Europe, America, Japan and other places every year.

Sweet carambolas have a long history of cultivation in Guangdong, my country, and the fine varieties include Guangzhou Liede sweet carambolas and Chaoan red sweet carambolas. These local old varieties have small fruits, with a single fruit weight of about 100 to 120 grams, a large core, thin flesh, more fleshy residue, more seeds, and a bland flavor. They are low-grade popular fruits with low market prices, and most fruit farmers do not plant them.

In the late 1980s, Singapore sweet carambolas were introduced from Singapore for trial planting in the Pearl River Delta. Shantou introduced Singapore sweet carambolas in Dongkeng Village, Xinan Town, Chenghai and Tashan Scenic Area, Lianshang Town in 1993, and has achieved initial success.

Growth environment

Carambola is a tropical evergreen fruit tree, suitable for economic cultivation in tropical and subtropical regions. Because it likes high temperature and high humidity, is relatively shade-tolerant, and is afraid of cold, drought, and wind, in suitable areas, it is also necessary to choose flat land with deep and fertile soil, sufficient water, convenient drainage, and facing south and leeward to build a garden; if it is built on a mountain, it is advisable to choose a south-southeast mid-low slope with water sources for irrigation, good soil quality, and a small slope.
