Is blueberry a persimmon in Northeast China?

Yes, blueberry is commonly known as persimmon.

I hope the following information can help you, and I hope to adopt it.

Persimmon, as a specialty of Shan Ye, has attracted more and more attention.

Because I don't know, I don't know much about it. There were several names just now. In Daxinganling, some people call it toast, in Yichun, some people call it blueberry, and in Heihe Aihui, they call it Du Shi. I continue to use the name of Du Shi persimmon, because Aihui in Heihe is the center of production, Aihui is the earliest provincial capital of Heilongjiang Province, and it is the earliest place to introduce and utilize Du Shi persimmon. Du Shi's persimmon is said to be Vaccinium uliginosum, also known as Du Shan persimmon.

There are several sayings in ancient books. Song Xiaolian introduced in Journey to the North: They are all woody, tall and plump, ripe in July, dark purple, small in shape, sweet and sour, and delicious. Russians use it to make wine, but China calls it wine.

Fang Shiji's "Longshaluo" said: Du Shi, love is muddy. Small and red, like mulberries, sour. (Note: Ai Hun is now Ai Hui. )

Persimmon, produced in the flat and humid zone between forests and valleys in Daxing 'anling and Xiaoxing 'anling Mountains, is mixed with other wild plants, and ripens at the end of July and early August, and the harvest period is about one month. Flowers bloom in June and fruit ripens in August. The fruit is slightly smaller than grapes, with purple flesh, crystal clear, thin skin, sweet and sour fruit flavor, fresh fruit juice yield of 75%, PH value of 3 ~ 4, unique taste, mellow and refreshing, slightly sour and sweet, bright and stable color, containing a variety of amino acids, a large number of vitamins and rich citric acid, as well as plant alkaloids.

Because Du Shan persimmons grow in the virgin forests of Daxing 'anling and Xiaoxing 'anling with cold climate, they are not polluted by any environment. Below the surface is permafrost, and above the ground is virgin forest. Persimmon is known as "Little Snow Lotus in Xing 'an" and has high nutritional value. It is an excellent raw material for brewing wine, making drinks, making fruit candy and jam, and can be eaten raw. Persimmon fruit contains a lot of vitamin B, vitamin C and various amino acids, and the amount of autogenous ethanol after fermentation is high.

Persimmon juice is a unique beverage, and the taste of persimmon wine is higher. Persimmon candy is deeply loved by children. Persimmon is also of high medicinal value, and has the effect of diuresis and detoxification. Chinese patent medicine can be used to treat kidney calculi's disease, gonococcal urethritis, cystitis, enteritis, dysentery and other diseases. Persimmon contains natural rhodopsin, flavonoids and anticancer active substances, which can keep people's vision for a long time, prevent brain nerve aging, resist fatigue, strengthen cardiovascular and cerebrovascular vessels and arteries, and have the magical effect of rejuvenation. As early as World War II, Britain specially gave persimmon jam to pilots of the Royal Air Force to enhance their vision when they were on duty at night. Later studies also confirmed that blueberries can accelerate the regeneration of rhodopsin, which is necessary for night vision in the United States. A team of researchers at Tufts University in Boston found that the mental state of elderly mice gradually improved after feeding them the food equivalent to a cup of blueberry fruit every day. After three months in a row, the mouse looks younger, smarter, more flexible, more coordinated and more energetic. Ramus Joseph, a neuroscientist who directed the study, said in a telephone interview: "The magical effect of mice eating blueberry fruits is unbelievable. What I want to do now is to drink a cup of blueberry fruit every day. "

I collected these comments from the internet. In my opinion, these are all about advertising statements, which are not necessarily credible. I only know that this food is delicious, and that's enough.

Wang Lichun's Five Views of Heilongjiang describes his experience of picking persimmons: I saw this long-lost thing when I was pushing in the grass. This tree is short, like a black beard, like a stout plum, and like a black grape. On the other side of Heilongjiang, they are called gooseberries, which have been read in many Russian classics. It was not until half a century ago that they matched the real thing. Maybe Russian gooseberry is pronounced persimmon, which has been accepted by our compatriots? It tastes sweet and sour, with a little mellow wine. If you eat too much, you will get drunk. Purple pigment has a strong permeability, and it is everywhere in everyone's hands, mouth and pockets. In a blink of an eye, it becomes a group of "purple tongue parties". I can't help smiling at each other. If a man and a woman go out and come back with purple lips and purple tongue, it's hard to make it clear.

The origin of wild persimmons is in the high-latitude mountainous areas of China. The frost-free period is short. Under this geographical and climatic condition, as long as the temperature is suitable, plants will grow, blossom and bear fruit quickly. The persimmon harvest period is about one month, which gives people a feeling of no hurry. In my opinion, the maturity of persimmon is not uniform, because it is characterized by mountainous areas, unstable temperature, inconsistent sunshine and moisture conditions, and naturally prolonged harvest period. In addition, the maturity of persimmon itself is really long, mainly because it is very resistant to preservation and not easy to deteriorate. The PH value is 3 ~ 4, and the sugar content is also high. Just like the local people's character, warm and mellow, practical and not mixed with water. The ventilation condition before picking is good (better than the ventilation condition of grape growing in clusters), and it is not easy to deteriorate. Persimmon fruit is white and slightly hard before ripening. When mature, the skin is black and covered with frost. The flesh is white as jade. The pulp contains very small seeds. For example, the seed of Northeast Mushroom Niang is so small that you can't feel its existence after eating it, but it is several times larger than the seed of persimmon. Only when people or birds and animals haven't picked it for a long time, or people have picked it for a long time, the pulp slowly turns rosy and becomes sweeter. The frost on the outside has also faded. As a wild plant, persimmon fruit mainly depends on small animals. Birds eat its fruit and pass seeds to it. The long storage time of fruits is more conducive to the spread of seeds. Therefore, people don't have to worry that persimmon will go bad like other fruits when picking it. What people call corruption is hard to produce on persimmons.
