Extended data selection method
Look and identify the skin color, pedicle and navel of melon. Where the melon shape is correct, the texture of the melon with flower skin is clear and the color is dark; Black melon should be black and shiny. However, the pedicel and navel of melon should be tightly closed, slightly retracted, and the rattan handle is close to the skin downward, and the stem is thick green, which is a sign of maturity.
Listen, take the watermelon in your hand and pat it gently with your fingers. If there is a crisp sound of "plop, plop" and the hand holding the watermelon feels shaky, it is a mature watermelon, and generally the melon taste will be sweeter. If the sound is boring and there is no vibration, generally such watermelons have not yet matured, so pay attention when buying them.
Three specific gravity, judging by the naked eye, two varieties of watermelon with the same size are melons with high maturity, and the heavier the melon, the lower the maturity. Because with the growth of watermelon, a considerable part of water will be consumed by transpiration in the later stage, thus accumulating more sugar (mortar), so the weight of mature watermelon is slightly lighter than that of watermelon of the same variety and size.
