The Peiligang Culture (9000-7000 cal. yr BP) in the Middle Yellow River region, North China, has long been considered representative of millet farming. It is still unclear, however, if broomcorn millet or foxtail millet was the first species domesticated during the Peiligang Culture. Furthermore, it is also unknown whether millet was cultivated singly or together with rice at the same period. In this study, phytolith analysis of samples from the Tanghu archaeological site reveals early crop information in the Middle Yellow River region, China. Our results show that broomcorn millet was the early dry farming species in the Peiligang Culture at 7800 cal. yr BP, while rice cultivation took place from 7800 to 4500 cal. yr BP. Our data provide new evidence of broomcorn millet and rice mixed farming at 7800 cal. yr BP in the Middle Yellow River region, which has implications for understanding the domestication process of the two crops, and the formation and continuance of the Ancient Yellow River Civilization.
黄河中游地区的裴李岗文化（9000-7000 cal. yr BP）长期以来一直被认为是小米农业的代表。然而，在裴李岗文化时期，哪种小米（黍或稷）首先被驯化，以及同期是否单独种植小米还是与水稻一起种植，目前仍不清楚。在这项研究中，对唐湖遗址样本的植硅体分析揭示了中国黄河中游地区早期的作物信息。我们的结果表明，黍是 7800 cal. yr BP 裴李岗文化中的早期旱地作物，而水稻的种植则发生在 7800 到 4500 cal. yr BP。我们的数据提供了新的证据，表明在 7800 cal. yr BP 的黄河中游地区存在黍和水稻的混合种植，这对理解这两种作物的驯化过程以及古代黄河文明的形成和延续具有重要意义。
