【摘要】 不同群体配置方式对菜用大豆的植株性状、青荚产量、叶面积指数、干物质积累量、干物质积累速度和各器官光合产物的分配均有不同程度的影响。每穴1株、2株比3株种植法青荚产量明显提高，单株干物质累积量增加，累积速度加快，光合产物在荚粒中的分配量分别增加1．11g和0．89g。更多还原

【Abstract】 A field experiment was conducted to study the effect of 3 population dispositions on yield and physiological index of vegetable soybean. The results showed that fresh pods yield, dry matter content and speed of dry matter accumulation perplant of one plant and two plants per hole were higher than that of three plants per hole respectively. the apportion quantities of photosynthate in pods were 1. 11g and 0. 89g higher than that of three plants per hole. Therefore population disposition by one plant and two plants per hole more reasonable.更多还原
