Analysis of Vegetative Food Structure of People Living at Ruins of A Xinmang Period Coin Minting Workshop,Discovered in Museum of Ancient Nanyang Prefectural Office,in Han Dynast

本文利用植物微体遗存的研究方法,对南阳府衙新莽铸币遗址出土石器表面残留淀粉粒,以及灰坑样品植硅体开展了分析工作。结果显示遗址人群当时加工食用的植物性食物种类包括栗、黍、稻、麦、高梁、豇豆属等谷物,薏苡、栎属等坚果,以及薯属、楼根、莲藕等根茎类,并以栗为主粮。高梁淀粉粒的发现,表明在新莽时期,高梁已经传入宛城地区,为我国高梁传播历史的研究提供新的证据。

This study uses the research method of plant microfossil remains to analyze the surface residues of stone tools and the plant phytolith samples collected in ash pits at the coin minting workshop site of Xinmang Period discovered in the courtyard of the Museum of Ancient Nanyang Prefectural Office.The results show that the plant foods processed by the population at the site included various types of grains such as foxtail millet,broomcorn millet,rice,wheat,sorghum,Vigna sp.,as well as nuts such as Job's tears,Quercus sp.and tuberous crops including Dioscorea sp.,Trichosanthes sp.,and lotus roots.Foxtail millet was the main staple grain.The discovery of sorghum starch grains indicates that sorghum had already been introduced to the Wancheng area during the Xinmang period,providing new evidence for the study of the history of sorghum dissemination in China.
