In addition, the more yellow the color of the grounded side, the better, indicating that the melon has become hot, such as cyan or beige. The instructions are not fully cooked.

Method 2: Look at the shape of the melon, the melon grows evenly and the umbilicus is deeply depressed, it is a ripe melon, and the crooked melon and the umbilicus are not dented for the raw melon.

Method 3: Listen to the sound of melons, hold melons with one hand, and play melons with fingers with the other hand. Those who make a crisp sound of "dangdang" are not ripe, those who make a "swelling" sound are ripe, and those who make a "fluttering" sound are overripe.

Look at the head and tail. The two ends are evenly proportioned, the umbilicus and the guati are deeply concave, and the surrounding area is full; Those with large heads and small tails or thick heads and tails are poor quality melons.

Third, the specific weight.

Compared with two watermelons, if the variety is the same and the size is the same, the lighter is the more mature melon, and vice versa, it is not very ripe, and the heavier the melon, the lower the ripeness. Because during the growth of watermelon, a large part of the water is evaporated and consumed, turning into sugar (i.e., sand). Therefore, ripe melons are lighter than melons of the same variety and size.

In addition, you can also put the watermelon into the water to observe, the one that floats upwards is a ripe melon, and the sinking one is a raw melon.

Fourth, the specific elasticity.

The skin of the melon is thinner, and the fragile one is pressed with the fingers, which is a ripe melon; If you scratch it with your fingernails and the skin of the melon is soft, it is an overripe melon.

Watermelon is the most common and popular fruit in summer, but some people don't pick watermelon, so the watermelon they buy is not sweet. In fact, there is a trick to how to choose watermelon, have you learned the above methods of how to choose watermelon?

Very simple. First, look at the navel of the melon, it is the end without the melon vine.

The melon is sweeter under the umbilicus, some people say that this is a mother melon, well, it's nonsense, in fact, the melon absorbs water normally during the ripening period, and the sugar is not diluted, so it is sweeter than the drumming navel melon that desperately absorbs water.

Second, look at the pattern, the melon body pattern is symmetrical and full, and each stripe can be clearly linked to the navel of the melon, which shows that the nutrient absorption of the melon is good, the sunshine is even, and the melon is easy to produce high sweet sand in the period of less rain.

Third, listen to the sound, the melon with a muffled sound is high in maturity, and the deeper the sound, the thinner the skin and firm flesh, and the less moisture, the higher the sweetness.

So remember the above three points, it is easy to pick out the sweet sand gourd.

Of course, if it is a local melon, it still depends on the rain, there is too much rain, even if you pick it according to the above three points, you can pick up a sweet watermelon at most, it is impossible to have a high sweetness, and the watermelon is sweet when the rain is less, this is the law.

Therefore, if you encounter Xinjiang melons, then sell melons according to the above three items, and you will not suffer a loss.

First of all, when choosing watermelon, you should first look at the color of the melon vine, the color of the fresh watermelon melon vine is emerald green, and then look at the shape of the melon vine, the watermelon that bends up is also relatively fresh, and then look at the texture of the watermelon skin, the texture is relatively uniform, and the neat watermelon is relatively high in maturity. The last point is to listen to the sound of the watermelon, gently pat it with your hands, if the sound is dull, then it proves that the watermelon is ripe.

Don't dislike this watermelon as much as Sister Pinpin's before, this kind of trace on the watermelon skin shows the number of times the bee touches the flower, the more pollination, the sweeter the watermelon.

In addition, watermelons generally have some spots on the bottom, which is the part of them that comes into contact with the ground during growth. The bottom spots of good watermelons are generally creamy yellow or even orange-yellow, while ordinary watermelons are white, so you can't go wrong with yellow spots!

Watermelon is delicious but difficult to choose, so let's learn how to choose watermelon.

Teach you how to pick watermelons.

Watermelon is delicious, many people won't choose, teach you the trick of choosing watermelon, delicious and fresh.

The quality of watermelon depends not only on the variety, but more importantly on its ripeness. Buying high-quality watermelons is mainly identified by looking, touching, checking and listening.

Look at the peel melons, the lines should be clear, and the shade should be distinct; Black melons, the skin should be black and shiny. No matter what kind of melon, the melon and the umbilicus are concave inward, the vine stalk is close to the skin of the melon, and the pedicle is thick and green, which is a sign of maturity.

Touch the melon skin with your thumb, feel that the melon skin is smooth and hard, it is a good melon, and the melon skin is sticky or soft for the second melon.

The more ripe the watermelon, the lighter it will be. Generally, watermelons of the same size are better for light ones, and raw melons for those that are too heavy.

Listen to the watermelon in your hand, gently flick it with your fingers, and make a crisp sound of "dong, dong", the hand of the melon feels a little trembling, it is a ripe melon; The sound of "sudden, sudden" is a reflection of a relatively high degree of maturity; Making a "poof, poof" sound is an overripe melon. It is the raw melon that makes the "click, click" sound.

How to pick a watermelon.

Look at the shape. First, identify the skin color of watermelon, guati and melon navel. The shape of the melon is upright, the skin of the melon is hard and full, the pattern is clear, and the skin is slightly uneven and wavy; The melon and navel are tightly closed and slightly indented, and the color of the melon skin against the ground turns yellow, which is a sign of ripeness.

Listen to the sound. If the sound is rigid and crisp, such as the sound of "knocking" or "deed" like tapping on a wooden plank, it is an unripe watermelon; If the sound is tired and muddy, similar to the "poof" sound of drumming and there is a vibrating sound, it is a ripe melon.

End weight. Raw melon contains more water and has a heavier body; Ripe melons, because of the fine crisp flesh and loose tissues, the weight is relatively lighter than that of raw melons.

If the skin of the melon is soft and black, the knocking sound is too heavy, the melon body is too light, or even the melon is shaken, it may be a rotten melon and should not be eaten. Some black-hearted traders will overuse ripening agents, hormones or red pigments, and even inject saccharin to increase sweetness, generally the stripes on the skin of this watermelon are not very even, and the color of the flesh is particularly bright after cutting, but the melon seeds are white, and there is a peculiar smell in the mouth.

The first point: whether the watermelon is ripe or not depends on whether the whiskers next to the melon are dry.

Each watermelon has its own individual "whisker", and the ripe watermelon has a characteristic: the whole melon vine is very green, but the whiskers next to the watermelon are dry. This is suitable for looking at when picking melons in the melon field, and you often can't see the whiskers when buying watermelons in the supermarket, so let's look at the second trick.

The second point: whether the watermelon is ripe or not depends on whether the pattern is scattered.

The pattern on the surface of the watermelon is scattered, after the melon is ripe, the pattern is scattered, and the pattern melon that is pinched together is not ripe, and the pattern can be seen in the early stage of the watermelon.

The third point: whether the watermelon is ripe or not is lifted up to see if it is "over-handed".

Hold up the watermelon and put it in the palm of your hand, and pat it on it with the other hand, and the vibration can be transmitted to the palm below, which is the ripe melon, which is called "passing the hand". When the raw melon eggs are patted, they can't be slapped, and they don't feel the vibration.

The fourth point: whether the watermelon is sweet or not depends on the flower pedicle.

What kind of melon is sweet and delicious? The selection of melons depends on the "flower pedicle", that is, the point behind the watermelon, the smaller the point, the sweeter the melon, especially the kind of small dot concave inside, the melon is particularly delicious; The bigger the dot, the less delicious it is, and after cutting it, there will be a lot of "white tendons" in it.

The fifth point: judge whether the watermelon is ripe or not.

When touching the surface of the watermelon, the feel is smooth, the melon is ripe well, the feel is oily, and the melon is not ripe.

The sixth point: determine whether the watermelon is a grafted melon.

Look at the melon vine, the thicker the melon vine, the greater the possibility of grafting, the finer the melon vine, the sweeter the melon, and the thicker the melon vine, the less delicious.

In order to pursue the yield of watermelon, many melon farmers will choose to graft watermelon with gourd, which has a very bad taste, and it is as "dull" as the taste of winter melon, and there is no taste of watermelon, and the vine is also very thick.

First, the smaller the circle at the bottom of the watermelon, the better, on the contrary, the larger the circle at the bottom, the thicker the skin, the more unpalatable:

Second, the watermelon head, which is the so-called pedicle, if it is a straight line, it is not wanted, but if it is curled up, it is very sweet:

Third, a watermelon with a neat texture is a good melon

Fourth, the color is best to choose blue-green, not foggy and white.
