How can you know that the watermelon is ripe, and how can you know if the watermelon is ripe or not

It takes a certain amount of time for watermelons to bloom from flowering to fruit growth to development, and the time from the opening to ripening of female flowers is also different depending on the variety of watermelon. In general, early varieties take 28-30 days to develop, medium-ripening varieties 30-35 days, and late-maturing varieties 35-40 days. How to judge whether a watermelon is ripe depends not only on experience, but also on the following methods.

Turn on step-by-step reading mode. How it works:

Judging by the appearance and form.

When the watermelon is ripe, the surface of the melon skin is very shiny, the pattern is relatively clear, the place where the corolla falls off and the melon handle shrinks inward and is concave, the color of the watermelon landing changes from white to yellow, and the hairs on the fruit stalk begin to fall. These can be used as the basis for visual observation.

Hand touch and listen to sounds.

Touching or patting the watermelon with your hands and listening to the sound can also determine whether it is ripe. Ripe watermelons are smooth to the touch and have a relatively hard skin, while unripe watermelons will have a rough surface to the touch. Hold up the watermelon with your hands and tap the surface of the watermelon with your fingers, if it is a ripe watermelon, it will make a "bang" voiced sound, and if it is raw, it will make a crisp sound.

Specific gravity method. Fruit specific gravity was determined. The specific gravity of ripe watermelon and water is not the same at room temperature. The density of watermelon with suitable maturity is that the proportion of raw melon is greater than and less than that of overripe melon.

The watermelon can be put into the water for observation, if the watermelon is completely sunk, it indicates that the raw melon, the surface part is very large; Indicates that it is overripe and does not surface much, indicating ripe melon.

Look at the melon seeds. After cutting with a knife, look at the melon seeds. The ripe watermelon seeds are black, while the ripe watermelon, although the melon is red, the seeds are still shriveled white, which is very easy to distinguish.

Taste the taste.

How to choose a watermelon:

1. Watch and listen to the sound. If the surface of the melon skin is smooth, the pattern is clear, the texture is obvious, and the bottom surface is yellow, which is a ripe melon; If the surface is hairy, dull, spotted and unclear, it is an unripe melon; If you play a melon with your fingers and hear the sound of "bang", it is a ripe melon; Those who hear the sound of "dangdang" are not yet ripe, and those who hear the sound of "poof" are overripe melons.

2. Look at the melon handle. The melon handle is green, it is a ripe melon, and the melon handle is black-brown, the hairs fall off, the curved and durable, the pure brittleness, and the tip of the curl whisker turns yellow and withered, which is an unripe melon.

3. 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.

4. Specific elasticity. The skin of the melon is thinner, and the fragile one is pressed with the fingers of Chang Zhang, which is a ripe melon; It is a gourd that is quietly cracked by the nails, and the melon is soft, and it is an overripe melon.

5. Handle it by hand. Those with a sense of emptiness are ripe melons; If there is a sense of sinking, it is a raw melon.

First look at the watermelon to see if there are white hairs around the roots, if there is raw, if it is smooth, it is ripe.

Tricks for picking watermelons: "pinch, play, check, touch, look". Pinch: Pinch the skin of the melon with your fingernails, the cooked skin is crispy and juicy, so it is easy to pinch in, and the skin of the raw melon is harder and difficult to pinch.

Bullet: Use the index finger or middle finger to hit the watermelon, if the sound is muddy and heavy, the sound of "bang bang" must be ripe melon; For example, it is raw melon that makes a crisp sound of "dang"; The "poof" sound is an overripe watermelon.

Ripe watermelons are lighter than unripe watermelons, but watermelons that are too light may be overripe or rotten. The watermelon with a pronounced heaviness is definitely a raw melon.

Touch: Ripe melons that feel hard and smooth to the touch, raw melons that are not smooth and sticky.

Look: The skin of the melon is smooth and bright, the dark green pattern is clear, there is no white hair, and the bottom of the melon is orange. 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.

How to judge whether the watermelon is ripe or not can be stroked with your hands, the melon skin is smooth and hard is a good melon, and the melon skin is sticky or soft for the second melon. You can also weigh it by hand, the higher the maturity of the melon, the lighter the weight, the same size of the watermelon, the lighter is better.

How to see if the watermelon is ripe or not ripe 1. Weigh the weight: The higher the maturity of the watermelon, the lighter its weight. 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, and gently flick it with your hand Zhaobo fingers, making a crisp sound of dong dong, and the hand of the melon feels a little trembling, it is a ripe melon. The sudden sound is a reflection of a relatively high degree of maturity; makes a popping sound, it is an overripe melon; It is the raw melon that makes the clicking sound.

3. Look at the appearance.

1) Look at the melon skin: The raw melon skin is green and bright. When the melon is ripe, the skin will darken in color.

2) Look at the melon navel: The melon navel will be concave after it is ripe, if you look at the ripe watermelon, you will understand the degree of depression, and then combined with the comprehensive judgment mentioned before, it is not difficult to know the raw and ripe of the melon.

3) Look at the head and tail: the two ends are symmetrical, the umbilicus and the guati are concave and deep, and the surrounding is full of good melons; The big head and small tail or the sharp head and thick tail are the poor quality melon Liang Xiang. The smaller the circle at the bottom of the watermelon, the better, and the larger the circle at the bottom, the thicker the skin, the more unpalatable.

4) Look at the melon handle: green, it is a ripe melon; Dark-brown, fluffy and frustrated, curved and brittle, and the tips of the curled whiskers turn yellow and withered, they are melons that are picked when they are not ripe. The melon stalk has dried up, it is ayahua, and the quality is poor; If the stalk is a straight line, don't do it, but if it's curled up, it's very sweet.

4. Touch the skin: touch the skin with your fingers, if the skin is smooth and really a good melon, if the skin is sticky and soft, it is a melon.
