【摘要】：本文对甘肃民乐东灰山遗址四坝文化时期的剖面采集的系列样品进行浮选所获得的炭化植物种子和麦类作物穗轴进行鉴定、统计和分析,结果表明,炭化种子以谷物类为主,各类谷物的比例和出土概率反映东灰山遗址四坝时期的农业经济,是经营以粟为主黍为次的小米类农业,小麦、大麦和裸大麦被普遍使用,以大麦和裸大麦为主的麦类作物,是当地旱作农业的补充。大量炭化裸大麦遗存的发现,为认识麦类作物种子的分类提供了很好的实物材料。与周边遗址的比较分析,我们发现河西走廊地区作为麦类作物传播的重要通道,外来的麦类作物并未取代小米类作物,仅为当地小米类农业的补充。
[Abstract]:In this paper, the carbonized plant seeds and the spikes of wheat crops obtained from the flotation of a series of samples collected from the section of the Siba Culture period in the Shiyishan site of Minle East Gansu Province were identified and analyzed. The results show that the carbonized seeds are mainly cereals. The proportion and unearthed probability of all kinds of cereals reflect the agricultural economy of the 4th Dam period of Dongliishan site. They are millet agriculture, wheat, barley and naked barley are widely used, and barley and naked barley are mainly wheat crops. It is a supplement to dry farming. The discovery of a large amount of carbonized naked barley provides a good material for the classification of wheat seeds. Comparing with the surrounding sites, we find that as an important channel of wheat crop transmission in Hexi Corridor area, the exotic wheat crops do not replace millet crops, but only supplement the local millet agriculture.
