最近,河南省文物研究所在整理距今7000至8000年的舞阳县贾湖遗址出土资料时,在房基或窖穴的一些烧土碎块内发现有掺和稻壳的印痕。通过扫描电镜的观察和现代稻壳的形态学比较,认为属栽培水稻。在出土的标本上可清晰地看出三条纵长隆起的印痕和其稃上的长条格状的纹路。稻壳印痕的长宽之比在2以下,具有粳稻特征;也有个别标本的长宽比大于2,具有籼稻的特征。稻是我国原始农业中的主要栽培作物。它的起源、分化和传播一直
Recently, the Henan Provincial Institute of Cultural Relics found the traces of mixed rice husk found in some of the burnt fragments in the base or cellar wells when sorting out the excavated data from the Jiahu site in Wuyang County, which was 7,000 to 8,000 years ago. By scanning electron microscopy and morphological comparison of modern rice husk, that is a cultivation of rice. In the unearthed specimens can clearly see the three vertical bulge marks and the long lines of the grid pattern. The length-width ratio of rice hull imprints is less than 2, and has the characteristics of japonica rice. Some species also have an aspect ratio of more than 2, which has the characteristics of indica rice. Rice is the main cultivated crop in China’s primitive agriculture. Its origin, differentiation and spread have always been
