Jujube
I know it at the mention
Because it is the sweet and sour taste of childhood for both northerners and southerners
But when a northerner and a southerner sit down to talk about sour dates, it is very likely that the chicken and the duck will not know what to do
The two men began to "get confused": Why don't my sour dates and his sour dates sound like a species?
In fact, there is no need to be "confused", because it may not be a fruit, because sour dates are indeed divided into north and south, and north and south sour dates are two completely different species.
China is rich in land and rich plant resources, and different plants have different names in different regions or
It's easy to get into a situation where we say different names that are actually a plant; when we say the same name, we don't actually talk about a species at all.
Today Inong wants to talk to you about the sour dates is like this, the common domestic, often mentioned sour dates, divided into two species in the north and south regions, the scientific names are sour dates and southern sour dates, in addition to some other plants or fruit names are also called "sour dates".
Everyone is a "sour date", so there is a problem of "mentioning it and knowing it, and being confused when you talk about it".
Next, Inong will give you to solve this "confusion", in order to avoid confusion, we only talk deeply about the similarities and differences, efficacy and economic value of the southern and northern sour dates, other "unknown" sour dates Inong at the end of the text a little mention, everyone has an understanding.
<h1 class="pgc-h-arrow-right" data-track="8" > "north and south, east and west" sour dates</h1>
The "north and south" of sour dates, in the literal sense, there are great differences between the north and south of sour dates; and "there are things" means that each of the "sour dates" mentioned in this article has a relatively wide range of uses and outstanding economic value.
Northern Sour Dates – Authentic sour dates
The reason why Inon says that the northern sour date is an authentic sour date is because only its official scientific name is the sour date; the other is because it is a real jujube in the botanical definition (in fact, the sour date does not have the nickname "northern sour date", and Inon wrote it only to distinguish the following southern sour date).
Let's take a look at the picture above, the fruit of the sour date is very similar to the jujube we commercially cultivated, can it not be different? People are "close relatives".
Sour jujube is a variant of the jujube genus Jujube of the family Lyceumidae, which originated very early, and was often called thorn in ancient times (in the Book of Poetry, "The kaifeng wind blows from the south, blowing the heart of the thorn."). Thorn heart death, mother's labor. "It is said that the sour date is), and at present, different regions have other names for them such as thorns, horn needles, hard dates, and mountain jujube trees (you said that it is not coincidental that the southern sour dates also have the nickname of "mountain dates").
Sour dates are mainly distributed in Liaoning, Inner Mongolia, Shaanxi, Gansu, Ningxia, Xinjiang, Hebei, Shandong, Shanxi, Henan and the northern part of Jiangsu and Anhui, due to the restrictions of suitable factors, there is basically no wild sour dates in the south of the Yangtze River. That is to say, when northerners talk about "sour dates", they are basically talking about it.
Because sour dates are varieties of jujubes, inonon compares ordinary dates with it, and the sour jujube plants are mostly shrubs, and the plants are relatively short compared with ordinary dates, and the fruits are smaller (less than 2 cm in diameter), and the round fruits are mostly red after maturity.
The flesh of sour dates is very thin, one of the biggest characteristics is acid, there are slightly sweeter varieties in different regions, but this "sweet" is compared with other sour dates, and compared with ordinary dates It is still sour. In addition, the core of sour dates is blunter at both ends than ordinary dates, and they are oval in shape.
Sour dates are very common shrubs in the north, in the past every August to September when the sour dates ripened, although the fruit acid is also definitely a mountain delicacy in the era of material scarcity, Inong is a northerner, when he was a child, he did not pick less to eat.
At present, due to the increasing variety of fruit categories, sour dates are rarely eaten as fresh fruits, although they are not eaten as fresh fruits, but sour dates are rich in rich influence substances, and their flesh is made into sour date juice, sour date sauce, sour date wine and other processed products, relying on wild, nutritious and other conditions, the price is really not low.
In addition, the economic value of sour dates is more reflected in the medicine, the medicine is the acid jujube kernel, here According to the farmer to explain a point, the sour jujube kernel is the seed kernel after the nucleation of the sour jujube (seed) is denucleated. As early as 2,000 years ago, the ancients of China wrote the sour jujube kernel into the pharmacopoeia "Shennong Materia Medica", "Compendium of Materia Medica" and other medicinal classics have its presence, the current sour jujube kernel is also an important Chinese herbal medicine, the Chinese Pharmacopoeia is entered into it (the reason why we want to mention this, because the following we want to mention another "sour jujube", that is, there is a dispute with it on the sour jujube kernel).
In addition, with the development and utilization of sour dates, we have found the economic value of many extracts in sour dates, and there are great prospects for development and utilization.
Southern sour dates - called dates are not dates
Let's look at the picture first
Although the southern sour date is the scientific name of the species, when southern friends mention it in informal occasions, they will not add a "south" word in front of the sour date, and "sour date" is its most common name.
The biggest difference between the southern sour date and the northern sour jujube is that in botany it has no half-cent relationship with the jujube, but the fruit looks more similar (here spit on the predecessors, the scientific name you give people a "southern sour jujube", it is too casual).
Southern sour jujube is a perennial tree of the southern sour jujube genus in the sumac family, which means that it and mango are close relatives, and the southern sour jujube originated earlier, and the tree age is very long, up to hundreds of years or even thousands of years.
There are many other names for southern sour dates, in addition to the recognized name of sour dates, there are also other names such as acetate fruit, snot fruit, sour date, five-eyed fruit, mountain eucalyptus fruit, jujube, mountain date and so on.
Southern sour jujube is mainly distributed in the southern region of China, Guangdong, Guangxi, Guizhou, Yunnan and other areas south of the Yangtze River distribution of wild populations, and then to the north of Jiangsu, Zhejiang, southern Anhui also distributed, but with the aforementioned northern sour jujube basically no cross distribution.
The southern sour jujube plant is as high as 10 meters, the fruit is mostly yellow after ripening, the fruit is larger than the northern sour jujube and is oval (about three centimeters), the core is larger and more characteristic, and there are five depressions on the core like eyes, and the nickname of "five-eyed fruit" is hence the name.
The pulp of the southern sour date is rich in gum, and it is also the role of sour to drool after one bite.
The use of southern sour dates is also very extensive, which can be described as a treasure of the whole body and a high economic value.
The fruit can be eaten fresh, but friends who can't eat sour don't try it easily, but the sour date cake processed from the pulp of the sour date in the south is absolutely delicious, and I believe this is also the childhood taste of many southern friends. In addition to the sour date cake, it can also be used for winemaking, and the fruit is also processed into a sauce fruit, which inonon has not eaten and does not know how to taste.
The core of the southern sour jujube fruit is prominent, once hyped as a hand string for a period of time, the initial price is quite high, many friends for this mountain full of wild fruit cores to pay a lot of IQ tax.
In addition, the bark and fruit of the jujube can also be used medicinally, and like most sumac plants, its bark and leaves can be extracted from quercus gum.
Inonon personally believes that the greatest economic value of the southern sour jujube is reflected in the fact that the southern sour jujube is a fast-growing and adaptable plant, and it is an excellent fast-growing afforestation tree species that can be used as a wood reserve.
The two main "sour dates" divided into north and south are finished, and the article will finally talk about other fruits with the name of "sour dates"
Still looking at the picture first, Inon introduced from left to right.
One is Hubei hawthorn, is a rose family hawthorn plants, mainly distributed in Hubei, Jiangxi two provinces, in both places have sour dates nicknames, Hubei hawthorn dried fruit can be used in medicine, in the inonon although not eaten fresh fruit, but the designation will not be much sweeter than other "sour dates".
The second is the false sour date, the scientific name is Lingnan sour date, is the sumac family betel nut green plant, calculated and the southern sour date is a close relative of the same family, mainly distributed in southern Yunnan, in the local sour date alias, false sour date fresh fruit should be the most "sweet" of many "sour dates".
The third is the Yunnan thorn jujube, which is the same as the sour jujube for the jujube genus of the family P. sylvestris, mainly distributed in Yunnan, Sichuan, Guangdong, Guangxi and other southern provinces, with other names such as hairy jujube, Burmese jujube, sour jujube and so on. The appearance of the jujube kernel and the sour jujube kernel is very similar, because the Chinese Pharmacopoeia is a sour jujube kernel, so it is usually characterized as a counterfeit, but in fact, it can also be used in medicine, but the medicinal effect may be different from the sour jujube kernel.
The above is the sour dates that Inong talked to everyone, and I hope that everyone will not be "confused" in the future.
In addition, there must be "sour dates" that Inonon did not mention, and what fruit do you have there that is also called sour dates?
