What method was used to cultivate rice in the south of Tang Dynasty?

Rice of the Tang Dynasty Nationalities

In the Tang Dynasty, millet and rice were the main crops, rice was widely planted by raising seedlings and transplanting, and a large number of early rice were planted, so the agricultural output was significantly higher than before.

Rice culture and history in different countries

All cultivated rice in the world are Asian cultivated rice. Asian cultivated rice originated from wild rice. In the past, scholars generally believed that the earliest cultivated rice originated from India to China and Yunnan. Since the rice was unearthed from Hemudu site in Zhejiang in the 1970s, the traditional concept has been impacted. It also triggered an upsurge in the study of the origin of ancient rice.

Rice and China

According to legend, Shennong taught farmers how to grow rice. China has been an agricultural country since ancient times. Rice was the main food of China people more than 3,000 years ago, about the Shang Dynasty. At that time, rice only had a glyph similar to the word "mortar". Later, when rice was planted in the Zhou Dynasty, it became more popular. As the rice ear stood upright, the word "he" was added. In the bronze inscription, a "claw" is added to the mortar, which is shaped like beating rice in the wind and pounding rice by hand.

As for the word "rice" in Oracle Bone Inscriptions, there were originally only six straight points, three points above and below, representing rice grains. Later, the middle points were connected to represent the shelf partition for putting rice, which became the word "rice". In the Eastern Han Dynasty, Xu Shen said in Shuo Wen Jie Zi: "Rice is no match for Shi Su". Such as the shape of grain. Later, in Chinese characters, "millet" is also called "millet" and "rice" is also called "rice"

It can be seen from the article that there is no doubt that China has a long history of planting rice, but many scholars still hope to find out the earliest rice or upland rice varieties, and some early rice has been found in many archaeological sites in Asia. For example, in 1995, four yellow grains of rice were found in Yuchanyan site, Dao County, Hunan Province, China, which can be traced back to 10000 BC and is considered as the earliest rice in the world. In addition, rice seed residues of about 7000 years ago were also unearthed in Hemudu in the lower reaches of the Yangtze River. Rice siliceous body cultivated artificially about 10 thousand years ago unearthed in Yingde, Guangdong Province. Some ancient rice in China was even replanted by scientists and added to hybrid rice varieties. [Source Request]

At present, China is also the largest rice producer in the world, accounting for 35% of the world's output. Indica rice is mainly produced in the south of China, while japonica rice is produced in the north. Today, the content of China people and national emblem includes the surrounding ears of wheat (golden harvest).

In the south of China, rice is commonly known as rice or millet, and there are hulled rice (mostly white, but also reddish (such as rouge rice), light green (such as polished rice), purple (such as Yunnan fragrant rice) and even black varieties. Cooked rice is called rice in the north of China, white rice in the south of China and handsome boy (from Chaozhou dialect) in Hongkong.

In recent years, China has actively studied rice and upland rice, and also developed the fastest hybrid rice research center to promote China agriculture to solve economic and food problems.
