How to choose when buying jujubes, and no longer worry about not being able to buy sweet and good ju

First of all, it is necessary to choose a jujube with a smooth surface, and secondly, it is necessary to choose a heavier jujube. Through the above two ways to choose, you can choose a more delicious date.

The best way to do this is to try it right now, so that you can buy something delicious and sweet.

Look at the skin of jujubesRed jujube is generally made by air-drying, and after air-drying, its skin will be relatively dry, because it is resistant to storage. When you buy jujubes, you should see if the skin of the jujube is sticky or moldy, and if so, it is not recommended to buy it. Looking at the color of jujubes, we all know that the skin color of jujubes generally has two kinds: bright red and dark red, and after natural air drying, the color of jujubes is generally brighter.

Looking at the size of jujubes, many people will only pick large jujubes when buying jujubes, but large jujubes are not necessarily good jujubes. There are many types of jujubes on the market, some large and some small, but it is best not to pick the big ones directly when we pick.

The first reason is that the weather is dry and the water is not irrigated in time, so the dates are not sweet. The second reason is that there should be organic fertilizers, not commercial fertilizers, urea and other fertilizers, jujube fertilizer is too serious. Our dialect here is a long scoop, and the dates are not too sweet.

On the other hand). The third reason is that jujubes generally have to go over a hundred roads to pick, and jujubes are ripe and sweet. If you can't shoot it before Bailu, you have to pick red dates to eat.

If you don't eat it as sweet as cotton, you will have diarrhea. Unreasonable fertilization, a large amount of chemical fertilizer, especially nitrogen fertilizer application too much, has a great impact on the quality, in order to make the jujube tree grow vigorously, can not apply too much nitrogen fertilizer. Because jujube trees are barren crops, they don't cost much on their own.

To improve the sweetness, you can use more organic fertilizers such as animal manure, which must be fermented and composted to make it fully ripe before fertilization, and then fertilized from the roots of the jujube tree with a ring of about 1 meter, or spot fertilizer. Dig a trench or pit 25 to 30 cm deep, add organic fertilizer, cover with soil and you're good to go. Too much watering is a drought-tolerant and barren crop of jujube trees, so there is no need to water too much, the soil moisture is high for a long time, and the jujube is not sweet and not delicious.

If there are climatic reasons (e.g. frequent rainfall, excessive soil moisture, or no means), drainage ditches can be dug manually to allow rainwater to drain through the drainage ditches. Reduce the adverse effects of rain. The photosynthesis of jujube leaves is not high, and the photosynthesis is not high, which will affect the synthesis and accumulation of nutrients, and the dry matter accumulation of jujube will affect the sweetness and taste.

While spraying foliar fertilizer on the insecticide to kill insects, it can provide nutrients to the leaves, make the leaves hypertrophied, strengthen photosynthesis, and ensure the sweetness of the dates. The variety problem of jujube trees has a long history of cultivation in China, with a wide distribution area and many varieties. The flat top and round bell in the northeast, the jujube and golden silk jujube in North China, and the teapot jujube and jujube in the south are all excellent.

But it has also degraded a lot. There are also bad species that have been mutated for a long time, coupled with the exchange of varieties between the north and the south, and the failure of cultivation, resulting in the unadaptation of jujube trees to water and soil, and the quality of jujube fruits produced is very poor. There have been jujube trees in my area for the past few years, what variety is it, what is its name, no matter how you wait, the fruit it bears should not be sweet, take a bite.

The taste is no different from wood carving. (It is a food).

Insufficient or unbalanced water and nutrients** for jujube trees. The jujube with a lot of fruit is also very large, indicating that the jujube tree has no problems during the fruiting and puffing period. Jujube tree) is in the ripening stage.

That is to say, in the ripening period, when encountering high fever and dry weather, the temperature difference between day and night is small, and the irrigation water cannot be irrigated in time, and the roots of jujube trees cannot provide enough water for jujube fruits, and the temperature difference between day and night is too small, which is not conducive to the accumulation of sugar.

The taste of home-grown dates is not good, which may be related to the variety of the tree and the local climate. In addition, the most important climate, normally speaking, jujube trees are more suitable for growing in the north, and the reason for the climate is that the jujube in the north is big and sweet. The jujubes grown in the south are relatively small, the flesh is relatively stiff, and the sweetness is also very low.

Therefore, it is normal for the jujube trees planted by yourself to have a bad taste of jujubes.

If the dates are not sweet in the first place, it is because the dates themselves lack water, I think it is necessary to water the dates in time, and secondly, the fertilizers used are unreasonable, the dates trees need to use organic fertilizers, and cannot use fertilizers containing nitrogen, so the dates do not grow well.

It may be because the pollution of the environment is too serious, so that the dates are not very sweet, or it may be because of the lack of moisture, as well as environmental reasons, so it is not good to pick up these dates.

1. Chenzhou crisp and bright brother base delicious jujube selection method: look at the color, the darker the color, the sweeter, many people mistakenly think that the color of the jujube is related to its freshness, the darker the color, the older the age, but in fact, once the jujube is picked, the color of the epidermis changes very little, the sweetness of the jujube can be judged by the color of the epidermis, the darker the color, the higher the maturity, and the sweeter.

2. Look at the fullness, when picking jujubes, don't blindly pay attention to the size of the jujube, but look at the fullness of the whole jujube, small jujubes, there is not too much pulp to eat, and the taste is average, and the large jujubes, the flesh is very thick, a lot, and it looks very fat, you can pinch the jujube with your hands, if you feel that the outer skin is very soft, and the flesh inside is very full, then it is a good jujube.

3. Observe whether there is a wormhole, there is no moth at the top of the stalk, the sugar content of jujube is usually 60%-80%, it is easy to be eaten by insects, and there is no handle at the top of the stalk to pay attention to it, if there is a small hole, it is eaten by insects, and you can also pinch it with your hand, and feel that the flesh is soft and empty, and it may also be moth-eaten.

4. Look at the appearance, the high-quality jujube is very full as a whole, and there are fewer cracks.

5. Look at the jujube meat, you can break the jujube meat to see the jujube meat inside, inferior or softened jujubes, the part of the jujube meat that is broken after breaking is brown, and the intact jujube meat is a hue when the whole jujube meat is broken.

6. Taste the taste, you can taste one first when you buy it, if it is very sweet, then it is a very good jujube.

Dates are not fully ripe, and it is also possible that organic fertilizers have not been applied during the growing season. Jujube is not sweet when it is not fully ripe, unreasonable fertilization, untimely pest control and control, insufficient sunlight, rainy weather, and poor variety quality all affect the sweetness of jujube fruit.

Fertilizer is unreasonable, a large amount of chemical fertilizer is applied, one is the weather. The second is the reason for the variety. The third is the reason for fertilization. The main reason is that the organic fertilizer is applied less, the fertilizer is applied excessively, the picking is too early, and the flavor has not yet formed.

How to choose dates, when choosing dates, the first thing to look at is the color of the dates, if a bunch of dates are placed there, there are white, yellow, red, and cyan. First of all, cyan dates can be excluded, cyan dates are generally not very sweet, the kind of white dates are generally very sweet, if there is no white, then buy yellow, red is not easy to say, it depends on the weight of the dates, if it is light, there must be no moisture in it, it is definitely not sweet, if you feel that it is very heavy in your hand, the water in the general dates is still quite a lot, it should be sweet.

Big green jujubes. The nutrition is not particularly different from ordinary jujubes. Vitamin C per 100 grams of jujubes

The content is between 75 mg and 150 mg, which is lower than those dates with high vitamin C content.

Daqing jujube is rich in fructose.

The content of fiber, especially vitamin C, is 5 times that of watermelon and pear.

9 times and 20 times that of apples, which can be called vitamin C fruit. It has the functions of promoting blood circulation, anti-oxidation, and enhancing human immunity.

Generally, pear dates and bell dates cannot mature until mid-September, and winter dates can not mature until early October.

Germplasm determines quality. It may be caused by the bad variety of jujube trees.

1. Look at the color of the jujubes. The color of a good jujube is purple-red, and the color of the jujube skin is darker, a bit like the color of red wine. And the color is relatively uniform and shiny, and the shape of a deep piece and a shallow piece rarely appears.

Most of the jujubes with slightly worse quality are dark red, and the surface luster is not obvious. The color is uneven, and some surfaces even appear black. Sometimes the uneven color of jujubes may be caused by too long storage time or insects, so we should pay attention to avoid these two kinds of jujubes when selecting.

2. Look at the shape of jujubes. The shape of a good jujube is generally uniform, oval or spherical, with fine wrinkles on the surface and no damage. Inferior jujubes, on the other hand, have uneven particle size, lose more moisture on the surface, and the fruits are shriveled, with deep wrinkles on them, and sometimes they are damaged.

3. Look at the cut surface. There is also a difference between the red jujube and the poor quality when cutting, most of the good jujube is cut neatly, the jujube core is smaller, the jujube meat is thick, the tightness is moderate, and the throat will not be stuck when eaten, while the inferior jujube generally shrinks a little more seriously, the cut surface will look dry up after cutting, and it is a little loose, the jujube core is larger, the jujube meat is rough, and the throat is sometimes stuck when eating.

4. Taste. The quality of jujube directly affects its taste, generally speaking, high-quality jujube tastes sweet, the taste is good, the jujube meat is delicate and non-sticky, and there is no miscellaneous taste. The poor-quality jujubes feel dry and dry, the taste is not good, the sweetness is not enough or with a sour and astringent taste, and sometimes residues will be left on the teeth after eating, and there are some inferior jujubes, which have a strange taste when eaten.

1. Look at the place of origin.

2. Look at the color.

3. Look at the sweetness.

Empirical Steps:1. Look at the origin: The best production areas of jujube are Shandong, Shanxi, Hebei, Xinjiang and northern Shaanxi, and it is sold like Gansu.

2. Look at the color: When buying jujubes, you should pay attention to the color of jujubes. If the color is too dull, it is not good in quality and quality. The oak round must choose red dates with good color.

3. Look at the sweetness: When buying jujubes, if you ask for the consent of the merchant. You can take a jujube and lick the skin of the jujube with your tongue. If the skin is sweet, don't buy it. Because the sugar content of jujube is distributed in the jujube flesh.

1. To look at the color of the jujube first, the naturally ripe jujube is purple-red, and the unripe appearance has some brown. In addition, the skin of new jujube has a natural luster, while the skin of aged jujube has no luster or a layer of hoarfrost on the skin.

2. Take a look at the appearance of jujubes, if there are small holes at the top of jujubes, it indicates that jujubes have been eaten by insects, and in addition, the epidermis of jujubes has scars and uneven color, which may be stored for too long. The good jujube particles are uniform, round or oval, and the lines on the jujube are fine and shallow.

3. Pinch the jujube by hand, if you feel that the flesh is firm, not dry, and the jujube core is relatively small, it means that the quality of the jujube is better and it is easier to store. If it is shriveled, it means that the quality of the jujube is poor.

4. Cut the jujube and look at the flesh of the jujube, the darker the flesh, the sweeter the jujube. In addition, the incision of good jujube is relatively neat and not loose.

5. Taste the taste of jujubes, good jujubes have a sweet taste, the fragrance of jujubes, the flesh is relatively delicate, and they are not sticky to the teeth, and the poor quality jujubes are not too sweet to eat, and they also have some sour taste.

1. Look at the appearance of jujubes. High-quality jujube is very full overall, and there are fewer cracks. When choosing, choose more ones with smooth skin and no scars.

2. When picking jujubes, don't blindly pay attention to the size of the jujube, but look at the fullness of the whole jujube. Small jujubes don't taste too much pulp, and the taste is average. And the big jujube has a thick, lot of flesh, and looks fat.

You can pinch the jujube with your hands, if you feel that the outer skin is very soft, but the flesh inside is very full, then it is a good jujube.

3. The skin of a good jujube is purple and red, the particles are large and uniform, the fruit shape is short and round, there are few wrinkles, and the traces are shallow; The skin is thin and the core is small, and the flesh is thick and fine; If there are many wrinkles, deep marks, and the fruit shape is concave, the meat quality is poor and the dried product made of unripe fresh dates. The darker the color, the sweeter. Many people mistakenly think that the color of jujube is related to its freshness, and the darker the color, the older it is.

But in fact, once the jujube is removed, the color of its skin changes very little. The sweetness of the jujube can be judged by the color of the epidermis. The darker the color, the higher the ripeness and the sweeter it is.
