Second touch: a good melon is slippery and hard to the touch, and a sticky or soft melon is a little worse.
Sandian: The riper the watermelon, the lighter it is. Therefore, watermelons of the same size should be lighter, and the overweight ones are not ripe yet.
Listen 4: Put the watermelon in your hand and pat it gently with your fingers, making a crisp sound of "dong, dong", indicating that it is a ripe melon; It is the melon with good maturity that makes a "sudden, sudden" sound; "Poof, poof" is a ripe melon; It's the raw melon that makes a "click, click" sound.
Five: Look at the melon handle. Peduncle is also an important part. If the stem is green, it means that this kind of melon is fresh and naturally mature. If the stem is dark brown and there is no fine hair, it means that this kind of melon is picked at an immature stage and is a "dead vine melon". The quality is particularly poor, so don't buy it.
5. There are three ways to choose high-quality ripe watermelon: look, touch and knock. A look at it is to look at the skin color of watermelon. There is a bend in the ripe melon, and then there is a root in the handle, which is different in color. You should choose the one with deep melon lines and light green skin. The surface is fuzzy, dim, mottled and unclear, and it is an immature melon. The second touch is smooth and round to the touch, not astringent to the touch. Three times means knocking on the top. If there is obvious vibration on the hand, it means that the pulp is vibrating and the watermelon is ripe. When you knock on the melon, the melon has a light floating feeling, and when you knock on the melon, the watermelon has a sound. Listen to the sound when picking melons. Knock on the melon with your fingers and hear a "bang", which is a ripe melon; Those who hear the sound of "Dangdang" are not ripe, and those who hear the sound of "poop-poop" are ripe melons.
