【摘要】：本文分析了河南淅川坑南遗址新石器早期2个层位出土的35件石制品的淀粉粒,在17件石制品表面发现150粒淀粉粒,它们可能分别来自黍族(包括黍属、糠稷或粟属)、薏苡属、小麦族秸秆和根茎类植物,一定程度反映了该地区先民植物资源的利用情况。第②与第③层淀粉粒数量和种类的对比表明,第②层淀粉粒数量和种类都有着大幅增加,一种可能是不同层位埋藏环境的差别导致淀粉粒保存情况的不同,另一种可能是与当时先民获取更多种类的植物资源有关。同一类型石制品表面淀粉粒数量与种类的差别,也暗示了不同石料本身硬度、孔隙对淀粉粒的吸附与捕获能力的影响。
[Abstract]:In this paper, the starch granules of 35 stone products unearthed from two early Neolithic strata at the South Xichuan site, Henan Province, were analyzed. 150 starch granules were found on the surface of 17 stone products, which may come from the millet family (including millet, bran millet or millet, Coix, Coix), respectively. Wheat straw and rhizomatous plants, to some extent, reflect the utilization of the resources of the ancestors in this area. The comparison between the number and type of starch grains in the second layer and the third layer showed that the number and type of starch grains in the second layer increased significantly, one of the possible reasons for the different storage conditions of starch grains was the different burial environment of different layers. Another possibility is related to the acquisition of more species of plant resources by the ancestors at that time. The difference in the number and type of starch grains on the surface of the same type of stone products also implies the influence of the hardness and porosity of different stone materials on the adsorption and trapping ability of starch grains.
