摘要： 密植条件下，不同群体结构对半矮秆大豆合丰42号影响较大。⑴随着群体密度增加，单株叶面积、干重、荚数、粒数降低，个体发育变差，倒伏加重；而群体干物重、叶面积系数、荚数、粒数及产量在一定范围内呈增加趋势；⑵合丰42号密植最佳群体结构为45株/m2，盛花期和满粒期叶面积指数分别为4.82和1.70，干物重分别为396.0g/m2和324.0g/m2，单株粒数47.1个，公顷产量为3578.3kg，较垄作对照增产18.3%。

Abstract: Under compant planting, there is the bigger effect of different population structure to the semi-short stalk soybean Hefeng 42. (1) With the density increasing, Hefeng42 showed its leaf area,dry matter weight,No. of pod,No. of seed of per plant decreased,
