摘　　要：以汕优63和武运粳8号为材料,测定了抽穗期的若干株型因子,并对不同群体的株型因子进行了比较。结果表明,高产群体的茎蘖发展合理,成穗率高,株高较矮,上部叶片的叶角小,叶片趋向挺直,叶片的相对高度较高,叶面积适中,叶片的叶绿素含量高。The main index of plant type in heading stage of rice were studied in population of different yield with Shanyou 63 and Wuyunjing 8, the results indicated that the tiller dynamics were reasonable and LAI was moderate in high yield population. The leaf angle of top leaves was smaller and the chlorophyll content was moderate too.
