澧县孙家岗遗址植物遗存分析

Analysis of Botanic Remains from Sunjiagang Site, Li County

通过对孙家岗遗址2016年度发掘采集的85份样品进行浮选和鉴定,获得了一批后石家河文化时期的植物遗存。其中农作物种子数量最多,包括水稻、粟和黍。农作物的分析结果显示,孙家岗遗址以稻作农业为主,并种植有粟、黍。粟类作物的出现再一次说明在新石器时代,旱作农业就已经传播到澧阳平原地区。

Through the flotation of 85 soil samples collected from Sunjiagang site during excavation in 2016, thousands of plant seeds were recovered. Among them, crop remains, including rice, foxtail millet and broomcorn millet, are in the majority. The flotation result suggests that the ancients mainly managed rice agriculture, as well as fewer rainfed agriculture. The occurrence of millet planting farming once again reflects that rainfed agriculture has spread to Liyang Plain in neolithic age.
