Now, kiwifruit is highly respected in China, as can be seen from some simple data - China's kiwifruit production is the world's largest, and nearly half of the cultivation area is in China.
Although the kiwifruit industry in China is very popular, you may have heard of New Zealand kiwifruit before contacting kiwifruit, so you may think that kiwifruit is an imported product.
In fact, kiwifruit is an overseas artificially cultivated variety of kiwifruit, and there are many similar varieties, which are not only similar in appearance, but also have basically no difference in nutritional composition.
And kiwifruit is a native Chinese fruit, it originated in China, this time Koreans can not grab it, because it has been certified.
The reason why you first heard of New Zealand kiwifruit is because kiwifruit is a fruit that has been domesticated for a very short time, and it was New Zealand that first domesticated kiwifruit and sold it to the world.

The origin of kiwifruit
Now kiwifruit has obviously become a bulk fruit like apples, plums, grapes, and the supply relationship has been fully formed on a large scale and industrialized.
However, kiwi fruit has really been known and recognized by the public for more than 50 years.
The origin of kiwifruit is Yichang City, Hubei Province, where the wild resources of kiwifruit are very rich, but this plant is dioecious, so the cultivation technology will be different from ordinary fruits.
In the past, the knowledge level of the Chinese people was limited, so no one really tried to cultivate kiwifruit, or it was difficult to promote it to the whole country.
Picture note: Kiwi seedlings
It wasn't until 1904, when a New Zealand schoolgirl named Isabelle Freser brought a bag of kiwi seeds to New Zealand, that the story of the kiwi fruit really began.
These seeds, nurtured by a nursery trader, Alexander Allison, had saplings that could be planted in large areas, and the "Hayward" we now know, as well as other overseas varieties, are basically the descendants of the bag of seeds that were brought to New Zealand.
The cultivated kiwi fruit has changed in both taste and storage conditions, and it has become more suitable for becoming a popular fruit.
The kiwifruit takes its name from New Zealand's national bird, the Kiwi, which does look a bit like kiwifruit.

However, Kiwifruit in New Zealand is not originally called by this name, or even classified as a fruit. At first, it was called meilong melon, but because the new Zealand melon tax is relatively high, it is not conducive to the promotion of the world, so it was renamed kiwifruit.
We know that New Zealand is easily linked to the kiwi (after all, it is the national bird), and it can be said that it comes with traffic, so businessmen named this bird purely to rub traffic.
Since the 1970s, this fruit because of its own rich nutrition, coupled with the vigorous promotion of merchants, it has a bunch of titles, what "king of fruit", "fruit of life" and other labels one after another, the price is also rising, I have the impression that it was once a high-end fruit, sold very expensive.
Now, many parts of China are growing kiwifruit, and its price has become very affordable, and the freedom of kiwifruit has finally been realized.
When there are more people planting, the market competition becomes more and more fierce, and you will eat more and more cheap kiwifruit, but you may also get more and more angry the more you buy.
Kiwi fruit falls to the altar
Many people who like to eat kiwi fruit may have such an experience, the kiwi fruit purchased on a website is very cheap, after receiving the goods, it is hard, after two weeks of ripening, it still does not become soft, and then after a while it becomes soft and directly broken.
I've seen a lot of people resentful on some platforms, but in fact, this is because it was picked early and picked before the fruit was ripe.
Kiwi fruit is a typical leap type of fruit, which is what we call "post-ripening fruit", when it is picked, it is not yet ripe, so we buy basically hard state, and need to be ripen with fruits such as bananas to be delicious.
Note: Respiratory jump - fruit growth and breathing relationship
This is because the jump type of fruit will experience a respiratory peak period, if it reaches this period, it will age rapidly, which is not conducive to sales and storage, so it is generally taken to pick before the respiratory peak period, and then reduce the respiratory effect in the form of refrigeration, slow down post-ripening and aging.
In fact, the ripening of the fruit is controlled by the regulation of internal ethylene, and after the fruit tree begins to bear fruit, the fruit will slow down and release ethylene to slowly mature itself.
The whole process of non-jumping fruit is smooth and orderly, but the leaping fruit is different, it will suddenly "unlock" the crazy output of ethylene at a certain period of time.
Chinese kiwifruit generally ripens in September and October, so it is generally picked about a week before September, and then refrigerated (or reduced oxygen exposure) to prevent it from entering the peak period of breathing, which is an ideal way to market.
We buy kiwifruit, add some vinyl to it, and then it will reach that peak of breathing on its own, frantically releasing ethylene to ripen in an instant.
Here and our conventional cognition is a little different, we generally think that we have ripened the fruit, but in fact, the maturity is basically on its own, and compared with the ethylene released by itself, what we provide is only a dime, which can only be regarded as a boost.
However, if it is too long before September, it will not work, because it will not be able to enter the peak of breathing when the large amount of ethylene is released.
The hard state that you buy on the market can't ripen and soften because of this, these fruits can't ripen at all, not your operation problem.
So can this unripe kiwi fruit be eaten?
The answer is: it can be eaten, but its nutritional value is not high, and the taste is not good.
For kiwifruit, July-September is a critical period for it to accumulate nutrients and sugars, and the hardbones we bought can't ripen, and many of them are already picked in July, so you can imagine how bad it is.
At last
The early harvesting of kiwifruit is no longer big news, even CCTV has reported on it, and it is now ordered to ban this behavior, because doing so is tantamount to drinking and quenching thirst.
Take kiwifruit, for example, now many of its reputations have been ruined by these early merchants, so many people dare not buy kiwifruit anymore, and even call it "kiwi escape".
As for why early harvesting, the reason is also very simple, the mall is slow, it is easy to lose everything, and when it matures, it will face greater competitive pressure.
In fact, not only kiwifruit, but also many fruits have similar encounters, such as durian, which was almost destroyed by "early picking".
Many of the durians we eat are imported from Thailand, and Thailand's response is that early harvesting will be sentenced, and it is not light, which finally curbs the early harvesting atmosphere, otherwise it is not to say that it is going abroad, and no one in their own country has bought it.
I hope that our early kiwifruit harvesting behavior can also be curbed, after all, we are the first kiwi country, and many ordinary people rely on this for a living!
