When was the watermelon introduced to China?
China is the largest watermelon-producing region in the world, but there are differing accounts of the watermelon's origin. The more widely accepted view holds that the watermelon's native home is Africa, where it was originally a wild plant of the gourd family and was later cultivated by humans into the edible watermelon. As early as four thousand years ago, the Egyptians were already growing watermelons; later it gradually moved north, first spreading from the Mediterranean coast to Northern Europe, then southward into the Middle East and India, and in the 4th and 5th centuries it was introduced to China from the Western Regions.
Why is the watermelon called "xigua" (western melon)?
The watermelon was introduced to China from the Western Regions in the 4th and 5th centuries, which is why it is called "xigua" (western melon). According to the Ming dynasty scientist Xu Guangqi's "Complete Book of Agricultural Administration", "the watermelon, its seed comes from the Western Regions, hence the name." Li Shizhen of the Ming dynasty recorded in the "Compendium of Materia Medica": "According to Hu Jiao, who obtained melon seeds in the Uyghur region, it was named xigua. Thus the watermelon first entered China in the Five Dynasties period, and today it is found in both north and south." This shows that the cultivation of watermelons in China already has a long history.
