1993～1994年间.曾对高邮龙虬庄遗址进行了考古发掘,在探方T3830中属新石器时期的五个文化层中,有四个文化层淘洗出炭化稻米4000余粒。本研究从炭化稻米的粒型及探方T3929剖面土样中水稻植物蛋白石的形态两个方面,对该遗址新石器时期的原始稻作进行了试探性分析。结果发现:(1)在原始稻作之初,粒型的变异是随栽培化的进展而增大的。(2)在该遗址的新石器时期早期,稻米的进化是缓慢的,在距今6300年至5500年之间,进化有一次飞跃,有意识的人工选择已产生效应。(3)从水稻植物蛋白石的形状分析来看,该遗址出土的炭化稻应当是粳型稻。
Between 1993 and 1994, an archaeological excavation was conducted on the site of Longjiaozhuang in Gaoyou. Of the five cultural layers belonging to the Neolithic Period T3830, four cultural layers scour out over 4,000 pieces of carbonized rice. In this study, we explored the original Neolithic rice from the aspects of the grain size of carbonized rice and the shape of rice plant opal from T3929 soil profile. The results showed that: (1) At the beginning of original rice cultivation, the variation of grain size increased with the progress of cultivation. (2) At the site of the Neolithic period, the evolution of rice was slow. Between 6300 and 5500 years ago, there was a leap in evolution and conscious artificial selection had the effect. (3) From the shape analysis of rice plant opal, the carbonized rice unearthed from this site should be japonica rice.
