There was little surplus grain in ancient times, so it was difficult for ordinary people to store it. In other words, grain is stored in sacks, vats and vats. There are many goods or granaries in the landlord's house, mainly dry and ventilated. In the case of stored grain pests infection, drying is a preventive measure. The national treasury preserves grain under dry and low temperature conditions, and uses the special technology of granary storage to achieve good storage effect.
Grain Depot is the Blood of a Nation —— Ancient Method of Grain Storage
The Book of Rites said: "It is not enough to say that the country has no savings for nine years. Without six years' savings, there is no hurry; Without three years' savings, a country is not a country. Rulers of past dynasties attached great importance to the cultivation and storage of grain. The ancient granaries include Dongnong granary in Xuzhou, Wuchang in Qin and Han Dynasties, Lejiuchang in Sui and Tang Dynasties, Xianjiachang and so on.
Take the world's first warehouse "Xian Jiachang" excavated in 1960s as an example. Its area is a unique discovery in the archaeological history of China and even the world. This huge granary has now found a total of 287 granaries, which are neatly arranged and are well-planned national granaries.
"Xianjiachang" not only has an amazing area, but also the grain excavated in the granary 1000 years ago is well preserved, which is almost the same as today's "Gu Zhen". This discovery is enough to show that the grain storage technology in Sui Dynasty was quite skilled. What is even more surprising is that some unearthed grains were sent to Luoyang Agricultural College. After special planting, they took root and sprouted normally, and the next year they bore fruit.
At that time, with the help of storage technology, the reproductive ability of grain seeds was still preserved after thousands of years, which was enough to shake the world. This shows that the "lip-to-lip" technology is very mature in moisture-proof and sealing, and the construction technology and grain storage technology in Sui Dynasty in China have reached a quite advanced level.
So how did you reach such an exquisite storage level at that time? There were three ways to store grain in the Sui Dynasty. The first is to ensure dryness, so the "Xianjiachang" was built in a place with high terrain and dry environment. Secondly, archaeologists found many traces of fire on the walls of the warehouse. Archaeologists have confirmed that this is what needs to be done before the food is poured into the warehouse. It is to dry the walls with fire to ensure the drying and sterilization of the warehouse. The third point is also the core stage of grain storage. This stage is more troublesome. According to historical records, the record of "laying the basement floor, planks, planks, mats, chaff and mats along the vegetation" is only the first step. After this, you should wrap the basement wall with mats, cover it with chaff, and finally cover it with mats. (Shakespeare, Hamlet) This process is not over yet. Finally, even if it is 0.5 meters from the ground, it is necessary to spread the bran of two mats. This method is the "cushion clamp" method specially invented in the Sui Dynasty to store grain.

This method continued until the Tang Dynasty. In order to ensure food safety, there was a formal "shelf life" for grain storage at that time. The "shelf life" of rice is 5 years, and the "shelf life" of grain is 9 years.
Besides salty singing, there are many famous songs in history. For example, when Chu and Han fought for hegemony, "Aocang" often became the object of contention between the two sides, and Liu Bang made the first move. Jun nutrition, the river of Changyang and Changdu. But then he added, "Heng combines the food shortage, fear and nutrition of Hanbok and Hanwang." Records in Historical Records clearly show the importance of the "five permanent members" in that war.
When the world was in chaos at the end of Sui Dynasty, Gu Chang also became the key to influence who could be king. After General Wu Li Mei captured Lejiuchang, a large number of hungry rebels surrendered, which laid the foundation for the growth of General Wu. Then, Li Mei accidentally lost "Le Jiuchang" and "Home Way Chang", and hundreds of thousands of people collapsed instantly. It can be said that it is "a little He Xiaohao".
Many historical materials about granaries fully show that grain was stored for thousands of years in ancient feudal society of China, which played a more important role in social relief and social security under the environment of emphasizing agriculture and restraining commerce. For a long time, the ancients in our country relied on superb wisdom to store food skillfully, which ensured the stability of the country and the people's lives.
