摘　　要：于南方丘陵稻田麦后茬选用夏大豆[Glycine max（Linn.）Merr.]新品种兴豆1号进行不同栽培密度和穴苗数试验,设密度水平和等穴异苗（每穴1~3苗）、等苗异穴各3个处理,共9个处理,考察各处理对夏大豆产量及植株性状的影响。结果表明,处理间产量差异显著;单位面积产量与有效株数、总荚果数、总粒数、单株实粒数等性状呈显著或极显著相关;不同处理主要改变植株的有效分枝数,其次是单株荚果数;每公顷播种18.0万穴、每穴留3苗处理的产量最高,达4.64 t/hm2。In order to investigate the influence of different planting density and seedling number on the yield and plant characters of summer soybean, the experiment was carried out using new variety Xingdou No. 1 as materials in the paddy field of southern hilly after the harvest of wheat, for 9 treatments of different density levels, the same number of points with different seedlings and the same number of seedlings with different points. The results showed that the yield of summer soybean were significant differences in different treatments, and the yield per unit area exhibited significant or extremely significant correlation with effective stalks, total pod number, total grain number and the number of seeds per plant. The different treatment mainly changed the number of effective branches of the plant, and then changed the number of pods per plant.The highest yield was 4.64 ton when planting density was 18.0 million points per hectare with 3 seedlings per point let.
