How do you pick up ripe watermelon when you buy it?

Basic common sense: According to different varieties, watermelons include large watermelons (more than 8 kg), medium watermelons (3 kg-5 kg), and small watermelons (less than 3 kg). Various watermelons are divided into thin-skinned and thick-skinned due to different varieties.

Among them, the thin skin can be divided into tough skin and crispy skin. Different characteristics determine the selection of melons, and different methods must be adopted.

Misconceptions about choosing watermelon:

1. Listen to the sound: Most people think that by listening to the sound, you can pick out a good watermelon. Various types of watermelons can be chosen by listening. In fact, different watermelons will have different sounds because of the thickness of the skin, toughness and crunchiness.

2. Look at the bottom of the melon: Most people think that if the bottom of the melon is yellow, it must be a ripe melon. In fact, sometimes when planting, because the bottom of the melon does not see the light, so, it may be there.

When it is three or four medium-ripe, it is already yellow.

Correct method: 1. Choose high-quality varieties: there are more watermelons on the market, small watermelons have Xiaolan, Black Beauty, medium-sized watermelons, etc., and large watermelons are generally less eaten along the coast. When buying melons, specifying varieties may have unexpected results.

2. Listen to the sound: The skin of the small watermelon is generally crispy, if you hear the crisp sound, the more cloudy may not be ripe. And other skin colors such as black beauty, because the skin is thicker, it sounds a little blinder, if it sounds like winter melon, it will definitely not be ripe.

3. Look at the skin color: Generally speaking, ripe watermelons are generally smooth and shiny, if you look like there are still bristles, it means that the ripeness of this melon may not be enough.

4. Look at the pattern: After the peel melon is ripe, the pattern can generally be scattered, if it is still tight, it will not work.

5. Look at the melon vine: In order to show the beauty of the melon, the current melon farmers will generally leave the melon vine for sale, as long as the tendrils of the raw melon are scorched, then it can. If not, then it's almost done.

The normal development of watermelon is sweet enough when it is ripe enough, so choosing a ripe watermelon is the right solution.

1. Look at the ground print.

The "ground print" is the place where the watermelon comes into contact with the ground, and as the watermelon gradually matures, the color of the ground print becomes darker. If it is white, it is not ripe.

2. Look at the melon handle.

The stalk of a freshly ripe watermelon is green, the stalk is dry, it may be a dieffa, if it is dark brown and the hairs are falling off, it may have been picked prematurely and not ripe.

3. Look at the lines.

These brown lines are caused by bee pollination, and the more pollination, the sweeter the watermelon becomes. The texture should be deep and clear, and the surface should be light and slippery.

4. Calculation method.

Count the number of days after flowering or the number of accumulated temperatures. Under certain climatic conditions, the number of days from the opening of female flowers to the ripening of fruits of a variety is basically fixed, and the accumulated temperature required is also the same.

It takes 25 to 26 days from flowering to maturity for extra-early maturing varieties, and the accumulated temperature is about 700. 30 35 days for early and medium ripening varieties, and the required accumulated temperature is 800 900; Late-maturing varieties are more than 40 days old, and the required accumulated temperature is more than 1000.

The accumulated temperature is calculated by adding up the average temperature of each day, or by multiplying the average daily temperature by the number of days using meteorological data. The higher the average daily temperature, the fewer days from flowering to maturity. Melons that bear fruit at different times on the same watermelon plant are early to mid-to-mid, and the number of days it takes to ripen is also different.

5. Hand measurement method.

Flick the melon with your fingers or pat or touch the melon with the palm of your hand. The dullness of the melon is a ripe melon. It produces a crisp and crisp sound for raw melon.

When you touch the skin of the melon with your hands, the one that has a slippery feeling is the cooked melon, and the one that is astringent is the raw melon. One hand to hold the melon, one hand on the top of the melon gently patting, such as the palm of the melon slightly trembling, the melon makes a loud sound is a ripe melon, such as the hand of the melon does not feel trembling, the sound of the sound is raw melon. Squeeze both ends of the fruit with both hands at the same time, put it in your ear and listen, if there is a hissing melon cracking sound, it is a ripe melon.

6.It was determined by a non-damaging melon and fruit tester.

Observations are made through indicators such as appearance color, bottom spots, pedicle condition, percussion sound, and flesh color and texture.

To judge whether the watermelon in the field is ripe, you can start with the appearance. Ripe watermelons usually have a bright and vivid skin color, such as dark green or yellow-green, rather than light green. The skin should be smooth and even, with obvious bumps or blemishes in the finches.

In addition, the bottom spots of the watermelon can be observed. Ripe watermelons will have yellow or cream-colored spots on the bottom, which refers to where the guati area touches the ground. If the spot at the bottom of the fruit is distinctly yellow or creamy, then the watermelon is likely ripe.

In addition to appearance, there are other ways to tell if the watermelon is ripe. Try twisting the pedicle of the watermelon, if the pedicle is easily twisted and the part that joins the fruit is dry or cracked, then this could be a sign of ripeness. In addition, you can gently tap the surface of the watermelon and listen to the sound.

Ripe watermelons usually make a dull sound, while unripe watermelons have a crisp sound. Finally, if you have the chance, you can cut a small piece of watermelon pulp to observe.

Precautions for watermelon planting

The watermelon in the puffing period needs enough water to grow, but the irrigation must be appropriate and even, you can irrigate once every 5-7 days, to keep the soil dry and wet, if the soil is dry and then wet, it is easy to crack the melon, so it is important to water with small water to keep the humidity uniform. Please note that if drip or sprinkler irrigation is used, it can be irrigated according to the actual conditions in the shed.

When planting watermelons, the fertilization is too blind, the amount of fertilizer exceeds the standard, and the rotten brother cannot achieve reasonable fertilization, usually the potassium fertilizer is not enough, and the nitrogen fertilizer exceeds the standard. In addition, when fertilizing, the amount of fast-acting fertilizer is excessive, the amount of organic fertilizer is insufficient or organic fertilizer is not used at all, so that after planting for several years, the phosphorus content in the soil exceeds the standard, and the nitrogen and potassium content is insufficient.

How to choose watermelon is delicious and sweet.

The first trick: shoot the watermelon.

This trick is definitely widespread, and the sound of unripe watermelons is relatively dull and low when filming. If the sound is empty when shooting, and there is a strong sense of vibration on the hand, it means that the watermelon has been overripe, and it is not delicious to buy such a watermelon.

The second trick: look at the color.

When buying watermelon, you will see that the skin of the same car of watermelon is also deep and shallow, some of the skin is smoother, and some are not so smooth, try to choose a watermelon with a darker color and smoother skin, because the watermelon will be more ripe and sweeter to eat.

The third trick: look at the lines.

Some watermelons have clear surface textures, and the depth of the pattern is distinct, so the watermelon is naturally ripe, if the texture of the melon skin is not particularly clear, or the texture is very distorted, then the watermelon may not be naturally ripe, and the taste will not be very sweet.

The fourth trick: look at the melon vine.

Many people have heard of a kind of "ayahuagua" saying, although these melons have been ripe, but they have grown on the withered melon vines, nutrition and sweetness can be imagined, look at the melon vines if it is bright green, it means that the watermelon is very fresh, if the melon vines wilt and yellow, it is not necessarily the legendary "ayahuagua" but it must not be fresh.

The fifth trick: look at the melon navel.

There will be a small circle-like depression at the other end of the melon vine, that is, the melon's navel, the more ** the melon navel, the thinner the skin of the watermelon, and the sweeter the taste, if the size of the melon navel is very large, the melon skin will be very thick, and the watermelon will not taste so sweet.

Raw watermelon has a certain amount of moisture, but the sweetness is relatively low, and the melon pulp is harder; Ripe watermelon, on the other hand, is not only juicy, but also sweeter and tastes better. So how do you choose ripe watermelon? Do you know how to do these techniques? I will, hurry up and learn.

How to choose ripe watermelon.

1.Look at whether the watermelon is ripe or not, and look at the color of the watermelon skin. Generally, ripe watermelons are bright in color, but if the skin of the melon is blue, it is likely that it is not ripe.

In addition, if the watermelon is not ripe, you can also look at the head and tail of the watermelon. Generally, if the head and tail of the watermelon are round, and the smaller the circle, the better, and the two ends are evenly proportioned, indicating that the watermelon is very full and ripe, otherwise, the watermelon will be a little raw.

2.If the watermelon is ripe, you can hold it up with your hand, and then gently pat it with one hand and listen to the sound of the beating to identify it. The watermelon that is not yet ripe will make a dull sound of "clicking" when the melon is beaten, while the watermelon that has grown ripe will not only make a crisp sound of "dong dong" when the melon is beaten, but also feel the slight tremor of the watermelon; If it makes a "poof" sound, it is likely that the watermelon is overripe.

3.Whether the watermelon is ripe or not can be distinguished by the method of peeling. Unripe watermelon, because the melon pulp is relatively tight and has a large moisture, so the weight will be heavy; Ripe watermelons, on the other hand, are relatively light.

Therefore, experienced people, for the same size of watermelon, by weighing its weight by hand, can quickly distinguish whether the watermelon is ripe or not, and the lighter one is the ripe watermelon.

4.Press the middle of the watermelon with your thumb, if you don't hear the sound, or the skin of the melon is hard and can't be pressed, it means that the watermelon is likely to be unripe; If you hear the sound of "sand, sand, sand" in the melon, it means that the watermelon is ripe.

2. Marking. After the female watermelon flowers open or pollinate, a 50 cm tall branch or bamboo strip is inserted next to the flower to mark it, and the upper end is painted with different colors. Change the color every 2 days and mark the single melon.

The ripening period is estimated according to the accumulated temperature or number of days required for each variety to mature. By marking the date of fruit set and checking the cutting of melons, the harvest is carried out at the right time according to the marking.

3. Look at the shape and identify the skin color of the watermelon and the melon and the umbilicus. The melon shape is upright, the melon skin is hard and full, the pattern is clear, the skin is slightly uneven and wavy, the melon and the melon navel are tightly closed, slightly indented, and the color of the melon skin by the ground turns yellow, which is a sign that it is ripe enough.
