2. Look at the melon fields. The part between watermelon and melon vine is called melon pedicle, and it can also be used to judge whether watermelon is delicious or not. If the melon pedicle looks small and curved, like a pig's tail, it means that this watermelon is ripe and has a high sweetness. Don't hesitate to do it quickly. If the pedicel is thick and straight, please don't buy it, because this kind of watermelon is still in its growing period and its taste is definitely not sweet.
3, look at the ass. Watermelon butt, that is, the bottom position, will cause color difference because of uneven sunlight, some are green, some are white, and even yellow. The bottom of watermelon is white and yellow. Try not to buy it. This kind of watermelon grows unevenly and its pulp will be different. We should try to choose watermelons with the same color.
4. Look at the navel of watermelon. Watermelon has a small depression at the bottom, just like our navel. If the navel of watermelon is larger and the depression is deeper, it means that the skin of watermelon is thicker and the sweetness is lower. On the contrary, the smaller the navel of watermelon, the shallower the depression, indicating that watermelon skin is thin and juicy, and the flesh is sweet and can be purchased.
5, shoot melons and listen to the sound. When you buy watermelon, you can pat it twice in a row and pay close attention to the sound it makes. If the sound is crisp and vibrating, it means that the watermelon is ripe. If the sound is dull and muddy, don't buy such watermelon, it must be immature.
