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。
Plant population, plantation pod yield, leaf area index, dry matter accumulation, dry matter accumulation rate and the distribution of photosynthate of various organs in different populations all influenced to varying degrees. 1 per plant, 2 plants per plant more than 3 plants. The yield of photosynthetic products increased 1.11g and 0.89g, respectively.
