The origin and producing area of rice cultivation history in China

Origin and place of origin: Wild rice has been domesticated for a long time to become cultivated rice. The remains of carbonized rice unearthed from Hemudu Neolithic Site in Yuyao, Zhejiang (see color map) and Luojiajiao Neolithic Site in Tongxiang are about 7000 years ago. The ancestors of these sites have been engaged in relatively settled farming life, so it dates back to the emergence of rice farming based on migration earlier

According to more than 30 years of archaeological excavations, more than 40 Neolithic sites have been discovered in China, especially in southern Jiangsu and northern Zhejiang in Taihu Lake area, followed by Hubei Province in the middle reaches of the Yangtze River, and the rest are scattered in Jiangxi, Fujian, Anhui, Guangdong, Yunnan, Taiwan Province and other provinces. Remains of the late Neolithic age have also been found in Henan and Shandong provinces in the Yellow River basin. The unearthed carbonized rice (or rice) can be divided into indica rice and japonica rice, which shows that the differentiation of indica rice and japonica rice has already appeared as early as the primitive agricultural period. Most of the above-mentioned rice plants are older than those unearthed in other parts of Asia, which proves the independent origin of rice works in China.
