Ginkgo tree is a living fossil in China, because its planting history is very long, and the tree itself appeared as early as the Carboniferous period 345 million years ago. With the evolution of the earth's history for such a long time, it can be said that most species are extinct, the most typical one is the extinction of dinosaurs, that is, the extinction of large herbivorous carnivores, but ginkgo trees survived, so ginkgo trees are called "living fossils".
Another characteristic of ginkgo trees is that they grow very slowly. Ginkgo trees need 10 years or even hundreds of years to bear fruit. The number of ginkgo trees will not increase much every year during the growth process, and it is a kind of tree that is difficult to reproduce naturally. There are few ginkgo trees propagated with solid wood.
A few years ago, because the number of ginkgo trees was scarce, the fruit of ginkgo trees was also very popular. We have a dish in the south, stewed belly with ginkgo biloba. Many people like this dish. Of course, there are stewed chicken with ginkgo and stewed pig's trotters with ginkgo, all of which are delicious. The most important thing is that Ginkgo biloba is rich in vitamins. Besides starch, protein, fat, sugar and other conventional ingredients, Ginkgo also contains trace elements such as vitamin C, so generally speaking, there are still many people who like to eat it.
However, it should be noted that there are certain toxins in Ginkgo biloba, which cannot be eaten raw. Raw ginkgo is too bitter for most people to eat. Ginkgo trees can only be used after processing.
After the ginkgo on the ginkgo tree is ripe, it should be picked first, then peeled off, cleaned and dried. After drying in the sun, it can only be eaten after high-temperature cooking. It is recommended to stew the ginkgo belly for a long time.
1. Why don't people want ginkgo nuts that have fallen all over the street now? In fact, since ancient times, there has been a saying that things are rare. If things are scarce and people's living standards are not high, they are very popular when people need them.
Just like a few years ago, some villagers collected these ginkgo nuts and sold them to people who collected ginkgo nuts for a few cents a catty. It was also an income for farmers in those years, and it could also solve some practical difficulties for them. For the sake of their families, they are reluctant to eat and want to keep it for sale.
Although it is difficult for ginkgo trees to grow solid wood, they can be developed by grafting and cutting. The ginkgo tree developed in this way has a short growth period, rapid development and a large number of ginkgo trees, so the ginkgo tree develops rapidly. Now, you can see many ginkgo nuts falling to the ground on the sidewalks of some streets.
Because of the large number, it is not unusual now. And with the improvement of people's living standards, people don't need to pick ginkgo nuts and sell them for a few cents, so no one picks them now.
Moreover, it is still difficult to process the picked ginkgo fruit, and it will take a long time to go through several processes, but its sales value is not so high, just like the current walnuts, sometimes it is two or three yuan a kilogram, which is far from enough labor costs, so some walnuts are hung on the trees and no one plays with them. That's the reason.
Moreover, ginkgo contains certain toxicity, so you can't eat too much. Beware of poisoning. Now no one wants ginkgo in the streets. what do you think? Welcome to exchange and discuss in the comment area.
