How to look at the surface of a watermelon is not sweet. Is there any way to discern this?

Touch the melon skin with your thumb and feel that the melon skin is smooth and hard, and the melon skin is sticky or soft for the second melon. OK. The more ripe the watermelon, the lighter its portion.

Generally, watermelons of the same size are better for light ones, and raw melons for those that are too heavy. Listen. Hold the watermelon in your hand, gently flick it with your fingers, and make a crisp sound of "dong, dong", and 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; makes a "poof, poof" sound, it is an overripe melon; It is the raw melon that makes the "click, click" sound.

I remember that there is a method in my hometown, which is to distinguish by the sound of slapping watermelons. I haven't tried it though, so you can do your own research.

1. Weigh the weight, the higher the maturity of the watermelon, the lighter its portion. Generally, watermelons of the same size are better for light ones, and raw melons for those that are too heavy.

2. Listen to the sound, hold the watermelon in your hand, gently flick it with your fingers, and make a crisp sound of laughing "dong, dong", and 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; makes a "poof, poof" sound, it is an overripe melon; It is the raw melon that makes the "click, click" sound.

3. Look at the appearance and look at the melon skin. The skin of the raw melon is green and bright. When the melon is ripe, the skin will darken in color.

Look at the melon navel. If you look at the ripe watermelon, you will understand the degree of depression, and it is not difficult to know the raw and ripe melon if you combine it with the comprehensive judgment mentioned before.

4. 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. 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.

5. Look at the melon handle. green, ripe melon; Dark-brown, furry and fluffy, curved and brittle, curled and yellowed at the tip, are unripe melons; The melon stalk has dried up, it is a "dead vine melon", and the quality is poor; If the melon stalk is a straight line, don't do it, but if the end gear is curled up, it will be very sweet.

1. Look:

Identify the skin color of melon and melon di, melon navel. The shape of the melon is upright, and the texture of the peeled melon is clear and distinct; Black melons, the skin should be black and shiny. The melon and melon umbilicus should be tightened tightly, slightly indented, and the vine stalk should be close to the melon skin, and the close to the pedicle should be thick and green, which is a sign of maturity.

2. Listen: Hold the watermelon in your hand, gently knock your fingers, if you make a crisp sound of "dong, knock", and the hand of the melon has a vibration feeling, it is a ripe watermelon, and the general melon flavor will be sweeter. If the sound is muffled and there is no vibration, generally such watermelons have not yet grown and matured, so you should pay attention when buying.

3. Specific gravity: Judging by the naked eye, the watermelon with the same variety and size of two varieties is the melon with high maturity, and the heavier the melon, the lower the maturity. Because as the watermelon grows, a considerable part of the water will be consumed by transpiration in the later stage, thus accumulating more sugar (sand pulp), so the weight of a ripe watermelon is slightly lighter than that of a watermelon of the same size of the same variety.

4. Cut: When buying melons, if you encounter a "gourd" appearance in the shape of a "gourd", flat melons, flat-headed melons, sharp-mouthed melons, pot-bellied melons, etc. are all deformed fruits, and deformed fruits are mostly caused by abortion or poor powder or other reasons, so it is best not to buy deformed melons. If the selection is really not good, it is best to ask for the melon to be opened and inspected on the spot.

5. Another way to pick watermelons is to weigh them, if they are similar in size and have the same fresh watermelons, it is recommended to choose a lighter one. The heavier one means that the watermelon has a higher water content, and it also means that the sugar content is diluted. In the case of the same variety of origin, choose those lighter to ensure that the sweet watermelon is picked, not the lighter the better, if the watermelon weight is too light, it means that the melon may be overripe, such a watermelon is greatly discounted in terms of taste and flavor.

This is divided into several cases, 1: plants.

Photosynthesis is required under sunlight to convert inorganic matter into organic matter. 2: The fertilizer applied by farmers is related, the farm fertilizer is mostly organic fertilizer, which contains many nutrients required by plants, and the watermelon will be very sweet if you apply more organic fertilizer.

Fertilizers, on the other hand, can only make plants grow too fast and contain not much organic matter. Therefore, the fruit fed with chemical fertilizer is not very tasty.

Don't be too strange in shape, and the crisper the sound when shooting, the better. The voice is low, and it's the kind that is about to go bad when it's ripe.

The thin-skinned, sandy melon is the sweetest, and then look at the origin, the watermelon of Inner Mongolia Bameng is the best, but in recent years, it can't be eaten, and it is particularly tasteful.

Watermelons are dark in color. Knock on the sound muffled. It means that it is naturally cooked.

The basic steps to pick a watermelon.

Pinch, pinch the melon skin with your fingernails, because the cooked melon skin is crisp and juicy, so it is easy to pinch in, and the raw melon skin is hard, it is difficult to pinch in.

In the second round, hit the watermelon with the index finger or middle finger, if the sound is muddy and heavy, the one that makes a "bang" sound must be a ripe melon; If it is a raw melon that makes a crisp sound of "dangdang"; The "poof" sound is made by ripe watermelons.

Three, ripe watermelon is definitely lighter than unripe watermelon, but it does not mean that the lighter the watermelon, the better, if it is too light, it may be overripe or rotten watermelon. The watermelon with a pronounced heaviness is definitely a raw melon.

Fourth, touch the watermelon with your hand, the hard and smooth feel is the cooked melon, and the unsmooth and light and sticky is the raw melon.

Five looks, the melon skin is smooth and bright, the dark green pattern is clear, there is no white hair, and the melon bottom is orange is a ripe melon; The color of the melon skin is not bright, the texture is not clear, the melon skin has fine hairs, and the melon handle is blue-green and has fine hairs. The one with the withered stalk is the dead seedling.

Sixth, sink the watermelon, put the watermelon into the water basin, and the one that can float to the surface is the ripe melon; Those who sink to the bottom must be raw melons.

Follow the six basic steps above to choose a watermelon to ensure that the watermelon you choose is sweet and delicious. However, in case of a miss, there are a few remedies:

1. Dig out all the melon pulp and put it in a bowl, add an appropriate amount of sugar and mix it, put it in the refrigerator for half an hour, and then eat it after the sugar dissolves, which is very sweet and delicious, and also has the effect of dispelling heat and quenching thirst.

Taste it and you'll know! Haha......

1. Look at the bai umbilical circle: the large umbilical circle indicates that the watermelon is raw

For a long time, the fruit is sweeter.

2. Look at the DAO

Guati: A curved version of Guati.

Sufficient nutrients are absorbed, high in sugar, and good in taste.

3. Listen to the sound: the sound of slapping watermelon is crisp and shocking, it is ripe, sweeter and more delicious; And the watermelon, which has a muffled sound and no sense of vibration, is not yet ripe.

4. Beating watermelon: the surface is hard and inelastic, the sound is relatively "bright", and the natural ripening watermelon is shocking.

Whether the watermelon is sweet or not, just look at the three places, and you can judge the ripeness at a glance!

The ways to distinguish whether a watermelon is sweet or not include looking at the texture, looking at the melon navel, looking at the melon vine, listening to the sound, and looking at the yellow part of the watermelon.

1. Look at the texture: The color of the ripe watermelon is relatively dark, the hail is cracked and the spacing between the grain sails is relatively wide, and the melon has a better taste and sweeter. And the immature watermelon has a narrow spacing between the lines and a poor taste.

2. Look at the melon navel: If the melon navel of the watermelon is relatively small, it proves that this watermelon is a high-quality watermelon, it has enough sunshine in the process of growth, it tastes sweeter and has a good taste. On the contrary, if the navel of the watermelon is larger and the skin is thicker, it means that the sweetness of the watermelon is not enough, and the taste is not good.

3. Look at the melon vines: Generally, the melon vines left on the melon head are green, which means that the melons are freshly picked and have a better taste. The melon vine has turned yellow and withered, and even the melon vine has dried up, which is generally the so-called "dead vine melon" or "early picking melon".

4. Listen to the sound: Ripe watermelon, we flick it with our fingers, the sound is a dull bang, and the more ripe the watermelon, the duller the sound. And the sound of the unripe watermelon is crisp when it is bouncing.

5. Look at the yellow part of the watermelon: The yellow part of the watermelon is generally produced by contact with the ground, if the area of the yellow part of the watermelon is smaller, it proves that the overall sunshine of the watermelon is sufficient, and the taste will be better.
