How to choose watermelons for   

  , look at the umbilical circle. Recently, it has been reported on the Internet and even on TV that the smaller the umbilical circle, the better. In fact, this is wrong. Because watermelon is a cucurbitaceae crop, its fruit is bottle gourd, which is a kind of fleshy fruit peculiar to cucurbitaceae melons. It is a false fruit developed from the inferior ovary of three carpels with lateral membrane placenta. On the other hand, the bottle gourd grows from the stalk to the navel circle, and the small navel circle shows that the watermelon does not grow long enough, and the navel circle is not topped round. On the other hand, watermelons with large, round and slightly sunken navel rings generally have sufficient growth time, and the fruit will be sweeter.

  , listen to the sound. Hold the watermelon in your hand and tap your fingers gently, if you make a crisp sound of "knock, knock", and the hands of the melon have a vibrating feeling, it is a ripe melon, and the taste of the melon will be sweeter. If the sound sounds stuffy and there is no sense of vibration, generally such watermelons are not yet mature and should not be purchased.

  , look at Guardian. From the bending degree of the pedicel, we can generally judge whether it is the first crop melon or the second crop melon. The pedicel of the first crop melon is curved, sufficient nutrition absorption, strong photosynthesis, high sugar content and good taste. On the other hand, the pedicel of the second crop melon is relatively straight, the taste is not as good as the first crop melon, and the size is not as big as the first crop melon. With the exception of watermelons grown by hanging seedlings in protected areas.

   is specific to weight. Judging by the naked eye, two watermelons of the same variety and size, the lighter the melon is, the more mature the melon is, on the contrary, the heavier the melon is, the lower the maturity is. Because with the growth of watermelons, a considerable part of the water will be consumed by transpiration in the later stage, thus accumulating more sugar (sand flesh), so the weight of mature watermelons is slightly lighter than that of watermelons of the same size.

The fruit shape was observed by   . If you encounter deformed melons when buying melons, the appearance is "gourd"-shaped, flat melons, flat-headed melons, pointed-mouth melons, big-bellied melons and so on all belong to abnormal fruits, and the narrow parts of watermelons taste bad, and most of the deformed fruits are caused by abortion or poor pollination or other reasons, so malformed melons must not be purchased.

The size of    watermelons is related to the degree of maturity. Huge watermelons are not the earliest to mature, but definitely not the latest, usually in the middle of watermelon ripening. Therefore, before most watermelons are not on the market, if you want to buy small and medium-sized melons, the probability of ripening is higher, while the ripening probability of large watermelons is lower. By the same token, when watermelons are on the market on a large scale, it is not appropriate to buy melons, but to buy melons. Small watermelons may be abortive vine melons in early-maturing varieties (early-planted watermelons).

There are three methods to test watermelon ripening by   . One is to observe the plant. Looking up and down from the vine where the pedicel is located, it naturally dries up, indicating that the growth of watermelon has come to a natural end and the watermelon has matured. Second, the method of listening to sound. Mature watermelons, there is a certain amount of water loss, so tapping with fingers, the sound is chaotic, while not very mature or raw watermelons, the sound is more crisp. The third is the stupid method. Put more than half a basin of water in the bucket. If the watermelon floats easily on the water, the watermelon is ripe, otherwise it is raw.
