摘　　要：以4个大豆品种(系)为材料,研究了菜用大豆在夏播条件下的生育特性及群体生产结构,并在此基础上研究了干物质积累分配及鲜荚产量的变化规律。结果表明:夏播菜用大豆的株高及叶面积指数表现为前期快速增长,从8月中旬开始增长缓慢;各品种(系)生育进程明显不同,合丰系列大豆生长发育迅速,生育期短,一般64 d左右即可采摘收获,最迟的品系是辽99011,从出苗期到鲜荚采收期需要79 d;辽00128各时期叶面积指数均高于其他品种;各品种(系)群体干物质积累的主要表现是在8月25日后,均以9月22日积累的干物质最高;辽00128干物质积累较多,同时后期分配到鲜荚中比例较多,鲜荚产量最高(8143.9 kg.hm-2),因此,辽00128适合在沈阳地区做夏播菜用大豆种植。Developing characteristics and population structures of vegetable soybean in summer sowing were studied by using four soybean varieties（lines）. Also the rules of dry matter accumulation and distribution and fresh pod yield were studied. The result showed that plant height and leaf area index （LAI）increased quickly in earlier stages,but decreased slowly after mid-August. The growing course between emergence to fresh pod harvest was different among varieties ,and Hefeng lines had the shortest growth period of about 64 days,Liao 99011 had the longest growth period of 79 days. Leaf area index of Liao 00128 was higher than others in any period. The population dry matter accumulation sharply increased after August 25 and peaked on September 22. Liao-00128 had higher dry matter accumulation, and distributed more dry matter to fresh pad in later stages and got the highest fresh pod yield of 8143.9 kg.ha^-1. Therefore Liao 00128 is suitable for summer growing in Shenyang area.
