摘　　要：为了寻求白浆土大豆最佳群体结构,改善大豆生长发育动态,提高白浆土大豆单产水平,选用品种、密度、行距3因素3水平正交试验设计(正交表采用L9(34)),对不同群体结构对白浆土大豆产量及生长发育的影响进行研究。结果表明:品种(F=43.63>F0.01=18.00)和密度(F=18.03>F0.01=18.00)均达到极显著水平,行距(F=9.28>F0.05=6.94)达到显著水平,各因素以选用半矮秆品种‘合农60’、密度55株/m2、行距17cm组合群体产量最高。群体株高和倒伏主要由品种基因型决定,LAI和干重主要受密度、品种遗传特性影响,其次是行距;‘合农60号’植株矮、节间短、秆强、抗倒伏,尽管个体性状较差,但群体性状较好。Three factors and three-level orthogonal experimental design was used in this test. The results indicated that： the plant height, LAI, dry weight per plant were all changed obviously along with the changes of different genotype varieties, densities, row spacing. Therefore, different population structures affected the soybean growth and development very large, which were all reached 0.05 or 0.01 significant level. That was to say, the population structure and soybean growth and development had very close relationship. Therefore, the use of dwarf varieties, increase density, reduce the row spacing was an important way to increase soybean yield.
