Can't eat it. Such a watermelon has gone bad, so let's pick a new one and eat it.

In this case, it is not recommended to eat in order not to cause diarrhea, pay attention to the diet.

Playing together, what else are you eating? That can't be eaten, it's already spoiled, and the watermelon that has been put bad is impossible to use anymore, which will have adverse effects on the body.

It is likely that the watermelon has been replaced with bacterial fruit rot, which will directly cause the watermelon to turn black and rot. Eating it will cause diarrhea.

No. Under normal circumstances, it is a very common phenomenon that there are white tendons in watermelon, which is the meridian of watermelon and the channel for transporting nutrients. Therefore, watermelon with white tendons can be eaten and will not have adverse effects on the body. Let's take a closer look!

Can you eat watermelon with white tendons in it?

Watermelon has white tendons in it, so it can be eaten with confidence.

The reason why there are white tendons in watermelon is related to the variety of watermelon on the one hand, and the weather is related to the weather, that is, the weather suddenly appears low or high temperature during pollination, and the temperature difference is large, which hinders the expansion of watermelon.

In fact, yellow tendon or white tendon is the nutrient delivery pipe of watermelon (similar to human blood vessels), which will generally fade naturally with the growth of watermelon, but if the watermelon grows in a harsh environment, such as high and low temperature, there will be residue when the pipe fades, but this will not affect the quality and taste of watermelon, so there is no problem with those watermelons with yellow and white tendons bought on the market.

Some people say that this kind of white gluten watermelon is hormone is also nonsense, after the watermelon is injected, the melon is easily eroded by bacteria, and the watermelon will rot in two days.

Watermelon selection tips.

1.Look at the bottom umbilical circle.

The quality of watermelon is raw and ripe, delicious and unpalatable, you can judge from the umbilical circle at the bottom of the watermelon, the smaller the circle, the better, on the contrary, the bigger the bottom circle, the thicker the skin, the more unpalatable.

2.Watermelon shape.

The watermelon 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, and slightly indented, and the color of the melon skin against the ground is slightly yellow, which is the watermelon is a sign of maturity, and it is a good melon, if the watermelon has a large head and a small tail or a thick head and a sharp tail, it is a melon of poor quality.

3.Watermelon color.

The appearance color of watermelon is best to choose blue-green, such watermelon is fresh and delicious, if the surface color of watermelon is foggy and white, do not choose, such watermelon is not sweet or fresh.

4.Watermelon pattern.

Watermelon has smooth skin, clear patterns, obvious lines, and yellow underside, which is ripe melon. The surface is hairy, dull, spotted and unclear, and it is an unripe melon.

5.Listen to the sound.

Those who play melons with their fingers and hear the sound of "bang bang" are ripe melons, those who hear the sound of "dangdang" are not ripe, and those who hear the sound of "poof" are overripe melons.

6. Look at the melon handle.

The guati is green, and the curvature is ripe and sweet; Guati is black-brown, fluffy, crooked and brittle, and the tips of the curled whiskers are yellow and withered, and they are melons that have been picked before they are ripe; The melon stalk has dried up, it is a "dead vine melon", and the quality is poor.

7. 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 will be 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.

8. Specific elasticity.

The skin of the melon is thinner, and the fragile one is pressed with the fingers, which is a ripe melon; Scratch with your fingernails.

I'm sorry I don't understand, but can you elaborate on that?

I am, watermelon has melanin in it. Melanin is a plant pigment that is an organic compound that is mainly composed of anthocyanins and chlorophyll. The skin and flesh of watermelon contain melanin, which protects against ultraviolet rays and protects plants from UV rays.

In addition, melanin can also inhibit the growth of cryptobacteria and protect plants from pathogens. In addition to watermelon, other fruits also contain melanin, such as grapes, strawberries, apples, pears, etc. Melanin not only protects the plant, but also the human body.

It can resist free radicals, prevent the damage of free radicals to the human body, delay aging, and protect human health.

The small watermelon that has just been knotted has the phenomenon of blackening, which is likely to be replaced by bacterial fruit rot, which will directly cause the watermelon to turn black and rot, if not treated in time, it will seriously affect the result. Therefore, to prevent it in advance, you can use alkaline copper sulfate suspension agent, spraying it once every 10 days for effective control.

When the newly formed small watermelon appears black, it is a kind of watermelon bacterial fruit rot, which directly causes the fruit to turn black and rot. Therefore, it is necessary to take preventive measures, start spraying 400 500 times of 30% alkaline copper sulfate suspension before the onset of the disease, once every 10 days or so, and prevent and control 2 or 3 times.

1. Conservation measures to prevent blackening

In order to effectively prevent the blackening of the newly formed small watermelon, it is necessary to loosen the soil at certain intervals to let the root system grow in a good environment, promote the lush and green branches and leaves, and promote the growth of fruits more fully. Be careful not to damage the root system during the soil dredging process.

Fertilizer should be applied regularly and reasonably, and the fertilizer must be rotted farmhouse fertilizer, and hormone fertilizers should not be used. Regular spraying of special elements, 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water can be used to evenly water the plants and promote the healthy growth of branches, leaves and fruits.

The blackening of watermelon leaves is common and may be caused by black spot disease.

Watermelon has brown spot disease leaf loss of green and loss of photosynthesis, which is caused by brown spot disease or anthracnose, and the main reason for the blackening of watermelon leaves is black spot disease. In the early stage of the disease, chlorothalonil, chlorothalontoin or mancozeb can be prevented and controlled, and various agents are used alternately.

In fact, black spots on the leaves of watermelon are symptoms of a variety of diseases, among which the more common is anthrax, anthrax is likely to appear in the whole period of watermelon, black spots are its initial symptoms, with the growth of watermelon, the black spots will slowly become larger, and will affect the quality of the fruit. Raised patches will also appear on the fruit of watermelon, which seriously affects the yield and quality of watermelon and causes great economic losses to melon farmers.

When the watermelon is ripe, the flesh is dark red and can still be eaten.
