A granary that has existed for thousands of years was discovered in Henan, with a grain storage capacity of 500,000 Jin. Can the grain germinate and be planted?

"A kind farmer": If you plant a millet in spring, you will reap 10,000 seeds in autumn. There is no waste of heaven and earth, and the toiling peasants are still starving to death.

Food is the sky for the people and food is the sky for the people. Without food, human beings can't survive. In ancient times, before people reclaimed land, they ate plants and animals. With the changes of the times and the progress of human civilization, the variety of crops is slowly increasing, from the initial millet and rice to a wide variety of crops now. These are symbols of the times and products of history.

Food has been difficult to preserve since ancient times, and people always worry about their food every few days in rainy and humid weather. Once the grain gets wet, it means that a year's work will be wasted. Therefore, in every dynasty, it is very important to store grain. From the emperor to the people, everyone will have their own ways to protect grain.

It is precisely because people of all ages are so clever that food can be preserved in the world. A Millennium granary was found in Henan, which contained 500,000 Jin of grain, and the grain could germinate. I have to sigh the super wisdom of the ancients.

This granary, named Hanjiacang, is the largest granary in ancient China and the "No.1 granary in the world" in the Tang Dynasty. It has a history of thousands of years and was built in the first year of Sui Dynasty. Hanjiacang, also known as Hanjiacang City, has a total area of 430,000 square meters and a large scale. It is located in Luoyang City, Henan Province. After three generations, the end of the Song Dynasty was abandoned by the war.

Many people will wonder why this granary was built in Luoyang. As we all know, Emperor Yang Di built the Grand Canal, which was also widely used at that time. With the development of the Grand Canal and society, grain is the main cargo to be transported, and Hanjiacang is a convenient place to transport grain. In addition, Yang Di moved its capital to Luoyang, which became the eastern capital of the Sui Dynasty. The natural population and economy are more developed than other places, not to mention the food consumed. In addition, building a granary in Luoyang is also convenient for the transshipment of materials, because Luoyang is an important transit point between Guandong and Guanzhong.

Although the Sui Dynasty was soon replaced by the Tang Dynasty, some facilities and equipment of the Sui Dynasty continued to be used in the Tang Dynasty, including Jiacang. Among the many granaries in the Tang Dynasty, Hanjiacang was the most valued, so that Hanjiacang accounted for half of the national grain at that time. The reason why Hanjiacang was chosen was because Emperor Taizong learned the lessons of his predecessors and stored the grain in the capital, which led to the scale and status of Hanjiacang.

No matter how brilliant things are, they will be abandoned one day, just as the prosperous Tang Dynasty will eventually be replaced by the Northern Song Dynasty, and the prosperity of Jiacang will inevitably decline one day. In the late Tang Dynasty, the water volume of the Sui and Tang Grand Canal decreased, the management was poor, the efficiency of water transportation decreased, and most granaries were abandoned, so the use of Jiacang was not the same. Only the 160 cellar was used until the Song Dynasty, and it was completely abandoned at the end of the Song Dynasty due to the war.

It was not until the late 1960s that Han Jiacang was discovered by later generations. After the official approval of the relevant departments, the Hanjiacang site began to be excavated in depth. Archaeologists say that there are more than 400 circular silos in Jiacang, among which 160 is the key silo, because there are still some grain in it. These lines are well preserved and clear, but the colors are different. After testing, 48% of these grains were carbonized and the remaining 52% were organic. What's even more amazing is that in this warehouse, the found grain particles still have vitality after being taken out, and the cultivated rice is no different from the present one.

The good preservation of grain is also inseparable from the geographical location and warehouse-building technology of Jiacang. The location of Hanjiacang is very particular. Its terrain is relatively high, the soil is very dry and the water level is low. These conditions are very conducive to grain storage. And its warehouse construction technology. At that time, when people used a warehouse to build a warehouse, they first dried the dug cellar with fire, then laid the plant ash on the bottom of the cellar, covered it with a layer of wood, covered it with a layer of mat, covered it with a layer of chaff, covered it with mat and covered it with chaff. So is the wall in the basement. Finally, a mat is laid and the soil is sealed, and a granary is completed.

In the face of such a magnificent Hanjiacang, we have to marvel at the wisdom of the ancients. The construction of Hanjiacang also shows that the ancients attached importance to food. Yu once said: the life and death of a country are inextricably linked with food. Grain can not only reflect the social situation, but also reflect the grain transportation, military information and architecture at that time.

The prosperity of a country cannot be separated from food, and the storage degree of food also reflects the situation of a country. China advocated frugality since ancient times, and his poems of compassion for farmers are well known. We should also cherish food and put an end to waste. "Zhu Zi's Family Instructions" has a cloud: "A porridge and a meal are hard to come by; Half a silk and half a wisp, it is difficult to think about matter. "
