Zhancheng rice is also called "Zaozhan", "Zaomi" and "Zaozhan City". Improved rice varieties in Song Dynasty. Zhenzong Dazhong Xiang Fu (1008— 102 1) was extended from Fujian to Jianghuai, Liangzhe and other roads.
According to legend, its species came from the country that occupied the city? (now Vietnam). It is early-maturing, early-maturing, drought-tolerant, fine-grained, suitable for high-lying fields, and has a certain role in preventing drought disasters in southeast China. In the Southern Song Dynasty, the planting scope was further expanded, especially in the east, west and Zhejiang roads in the south of the Yangtze River. The combination of Zhancheng rice and late rice forms double cropping rice, which greatly increases the grain yield.
Zhancheng rice is an excellent rice variety in Song Dynasty. Zhancheng people cultivated an excellent rice variety, which was introduced to Fujian, China in the early Northern Song Dynasty. 10 1 1 year, due to the drought and water shortage in the Jianghuai and Zhejiang regions, Song Zhenzong sent envoys to Fujian to collect 30,000 hectares of rice, which were promoted in the Yangtze River, Huaihe River and Zhejiang regions respectively, and ordered the forwarder to post the post "Rice is longer than China, with no awn, small grain difference and excessive growth".
Zhancheng Rice in Song Dynasty was a typical exotic crop variety in ancient China. It was introduced into Fujian in the late Tang Dynasty and the Five Dynasties, and then spread northward under the leadership of the Song government. Its outstanding excellent quality makes it the dominant grain crop in the Yangtze River valley, and with the different geographical environment, many new varieties have evolved one after another. Therefore, Zhancheng rice has a far-reaching impact on the rice farming system in the Yangtze River basin.
The introduction of Zhancheng rice is undoubtedly the result of the development of foreign trade. The information about Zhancheng rice is most widely recorded in Shi Shi Shi Shi Foo, the most detailed in Shi Shi Shi Shi Foo, and the most specific in Three Mountains in Xi Chun (before and after Zhancheng).
Zhancheng rice not only refers to the rice planted in Zhancheng country, but also refers to the common rice varieties in Indochina countries. Took up all the grain in the city, led by rice. The article "The Country of Real Wax" in this volume also says: "The soil is fertile, the land in the field is in sight, and the rice is flat."
Annan, Zhancheng (also known as Lin Yi and Guo Huan) and Zhenla in Indochina Peninsula are rich in rice. Because of extensive agriculture and no irrigation facilities, rice can grow naturally. This is similar to the situation in Guangxi. Until the Southern Song Dynasty, the cultivation method of upland rice outside the ridge was like this. The article "Idle Farmers" in the third volume of "Answering the Generation Outside the Ridge" said: "It is no longer easy to plow just by taking broken pieces, but to plant them in the fields without moving seedlings.
After planting, the drought will not find water, the waterlogging will not be alleviated, there will be no manure and no soil, and no farming will be carried out. The characteristics of drought and waterlogging tolerance of Zhancheng rice may be formed under this specific natural environment and extensive farming methods. Although Zhancheng Rice is famous as Zhancheng Rice, it is widely planted in Guangxi, Annan, Zhancheng, Zhenlai and other countries.
Ambassador Zhancheng once presented Zhancheng rice as a tribute to the Song Dynasty. Due to the short growth period, Zhancheng rice was popularized rapidly in the Song Dynasty, which increased crop yield.
