The Song Dynasty is often described as "weak Song" by some of us. In fact, the Song Dynasty cannot be said to be very weak. You know, the Song Dynasty was the first country in the history of the world with a population of over 100 million. In ancient times, population was a very important resource, and that was one of the important criteria for being an "empire." From this perspective, it is not very fair to say that the Song Dynasty is a "weak Song".
According to historical data, in the Song Huizong periodIn the Song Dynasty, the number of households nationwide reached more than 20.88 million, with a total population of about 120 million! At that time, the world's population was just over 400 million. The Song Dynasty’s population accounted for a higher proportion of the world’s population than China’s now.
The Song Dynasty is the smallest dynasty in the history of China. If the Northern Song Dynasty is included in the current Chinese territory, it can only be regarded as a relatively safe dynasty. So, why can the Song Dynasty feed 100 million people?
This is entirely due to rice, but a kind of imported rice-Champa rice, imported from Champa, Vietnam.
According to "Song History" records, during the Song Zhenzong period, as long as a drought occurs in Jiang, Huai, and Zhejiang, the whole country will Rice is in desperate situation. In order to get rid of this predicament, Song Zhenzong ordered to find a rice seed that is not so dependent on paddy fields. Later, it was really found. Fujian officials found a high-yielding, early-maturing and drought-tolerant one in Champa, Vietnam. The rice species is Champa rice.
How good is this kind of Champa rice? According to the record of "Ling Wai Dai Da Da Lazi Nong": "Drought does not ask for water, flood No negligence, no dung soil, no stubborn soil, and no stubbornness. Champa rice is not afraid of droughts and floods. It does not need to fertilize or go to Dali. In short, it is very easy to feed and can reduce the need for food to depend on the sky. risk.
But in fact, Champa rice was not introduced to China during the Song Zhenzong period. As early as the late Tang and Five Dynasties, Champa rice was grown in Fujian and other places through private channels, but because there was no official promotion , Has not been noticed by people.
Since the introduction of Champa rice, it can be grown not only in Jiang, Huai, and Zhejiang, but also in the hilly areas of the south and the north Dry land can be planted, greatly improving land utilization, increasing national food production, and solving the problem of food.
The problem of eating is solved, and the natural population increases. By the time of Song Huizong, the population exceeded 100 million. It’s weird. Later in the Southern Song Dynasty, the site was smaller, but it was able to feed such a huge population and fight against the northern peoples for a long time. It can be said that Champa rice is indispensable!
