What kind of watermelon is red and sweet, watermelon is very red and sweet but very hard

Watermelon tastes very hard and cannot be eaten. Watermelons are grown with excess bulking hormone and erythrocin, which can make watermelons look beautiful but uneven. Red-spurring spur can make watermelon look particularly bright in color, but it tastes very hard.

The yellow-green stripes on the skin of the melon are uneven, and the melon pulp is particularly bright after cutting, but the melon seeds are white and have no sweet taste. Watermelons with bulking agents are large and can reach 6 to 10 kg. Generally, it is normal for watermelons to weigh around 4 kg.

The watermelon that has been used with hormones in the shed let the branches, due to the spraying of pesticides and uneven absorption, is prone to crooked melon deformity, such as asymmetry at both ends, depression in the middle, swelling of the head and tail, etc., and there are color spots or large color differences on the surface. A normal watermelon should be spherical or oval in shape and have a flat and smooth surface. It is cultivated all over China, and there are many varieties, exocarp, pulp and seeds in various forms, and the most famous ones are Xinjiang, Lanzhou, Gansu, Dezhou, Shandong, Dongtai, Jiangsu and other places.

Its original species may come from Africa, and has been widely cultivated in the tropical to temperate zones of the world for a long time, and was introduced to China in the Jin and Yuan dynasties. Watermelon is a summer fruit, the flesh is sweet, can cool down the heat; The seeds contain oil and can be used as recreational food; The peel is medicinal, and has the effect of clearing heat, diuresis and lowering blood pressure.

Under normal circumstances, the sweetness of the fruit is directly related to the temperature difference between day and night in the place where it is grown, and the fruit that grows with a larger temperature difference is sweeter. In addition, the sweetness of ripening with hormones is also poor. To sum up, I personally think that the biggest possibility is ripe watermelon, because the growth time is too short, there is no process of sweetness accumulation, and red only means that it is ripe.

Watermelons are divided into varieties, some are beautiful on the surface, but not sweet on the inside, and some are not good-looking on the outside, but very sweet on the inside!

Now the watermelon, hit the potion of what color and size. Yikes

Black seeds are mostly inside, occasionally mixed with white seeds.

Watermelons that are all white seeds or seedless can be excluded. Then look at **, because of the limitation of production, 8424** is high, generally higher than the market price, less than 4 yuan should be cautious, consider whether to sell dog meat on the head of a sheep.

Precautions for buying watermelon

1. Look at the weight. Try to choose the heavier one for the same size watermelon, because such watermelons are juicy to eat.

2. Look at the color. To choose the blue-green purchase, because such watermelons are fresh, you can also look at the color of the watermelon melon vine, the color of the melon vine is cyan also indicates that the watermelon is fresh. The color of the melon vine is yellow, which means that the watermelon will be left for a long time.

If you want to choose the sweetest watermelon, you mainly look at the texture, the melon vine, and the melon navel.

1. Look at the texture.

The general texture of watermelon with good growth B is relatively neat and clear, and the general skin is dark green; The spacing between the lines of ripe watermelon is relatively wide, and the texture is slightly concave when touched by hand, among which the widest texture is the sweetest.

2. Look at the melon vines.

Melon vine, the academic term is the head of the stem, and the choice of the sweetest watermelon with the widest penetration is to choose the watermelon with the curved head of the stem. The curved head of the tip indicates that the watermelon has a long growth time and more nutrient accumulation, and the sweeter the watermelon. You should also choose the fresh head, which means that it has just been picked.

3. Look at the melon navel.

Generally speaking, the smaller the navel, the sweeter the watermelon; The larger the navel, the thicker the skin and the lower the sweetness. If you touch it, the ripe watermelon will have a slight depression in the navel, and the one without the depression is the raw melon.

The environment in which watermelons are grown

Watermelon likes a warm, dry climate, not cold-tolerant, the optimal temperature for growth and development is 24-30 degrees, the optimal temperature for root growth and development is 30-32 degrees, and the minimum temperature for root hair occurrence is 14 degrees. Watermelons require a large temperature difference between day and night during growth and development. Watermelon is drought-tolerant and not humidity-tolerant, and when there are many rainy days, the humidity is too high and it is susceptible to disease.

Watermelons love light, and watermelons have a long growth period, so they need a lot of nutrients. With the growth of the plant, the amount of fertilizer required by the watermelon gradually increases, and reaches the maximum value when the fruit grows vigorously. Watermelon has strong adaptability, and the best is loose soil, deep soil layer, and well-drained sandy soil.

Likes weak acidity, pH 5-7.

The sweetest way to pick a watermelon: look at the pattern of the watermelon's skin, look at the navel of the watermelon, and pat it to listen to the sound.

1. Look at the watermelon skin pattern.

Watermelon skin is patterned, these patterns have horizontal stripes, there are also vertical stripes, due to the expansion of watermelon, the pattern of the skin will also change, when choosing watermelon, to choose the pattern width is consistent, continuous watermelon, such watermelon is generally sweeter.

2. Look at the navel of the watermelon.

In general, the smaller the navel of the watermelon, the thinner the skin of the watermelon, and the sweeter the taste. This is because in the process of growing watermelon, the more ripe the watermelon grows, the flesh inside the watermelon will become larger and larger, and the navel position of the melon will shrink and become smaller and smaller.

3. Pat and ask for the sound.

Generally speaking, when the watermelon is beaten, the beam is slapped, and when the "sudden" sound is made, it means that the watermelon is ripe better, and when the "sneer" sound is made, it means that it is too ripe, and when the dull "Peng" sound is made, it means that the watermelon is very raw.
