Watermelons become larger and heavier when they are ripe, and they generally grow on the ground.If the watermelon is set up to breed, when it matures, it will fall because of its heavy weight, which will easily break the watermelon and affect its economic value.Therefore, watermelon usually grows on the ground.
Watermelon has strong adaptability, and cold and high temperature resistance, can be planted in different seasons, can also be planted in different areas.Watermelon in China is mainly planted in Hainan, Guangxi, Jiangsu and other southern regions.Because of the superior environmental conditions, the watermelons produced in these places are not only large, but also high in yield.Most of the common watermelons on the market are produced in these areas.
Watermelon was originally a wild plant of the Cucurbitaceae family. It was later cultivated into an edible watermelon.About 4000 years ago, watermelon was planted in Egypt, and then gradually spread.It first spread from the Mediterranean coast to Northern Europe, then to the Middle East, India and the Western Regions, and then to China.At that time, it was about the fourth and fifth centuries, so our country also had a very long history of watermelon cultivation.
