摘　　要：以高蛋白大豆新品种圣豆24为试验材料,通过3个播期处理(6月5、15、25日),研究不同播期条件下大豆生育期、干物质积累分配及产量的变化情况。结果表明,随着播期的推迟,大豆植株总生育期逐渐缩短,尤其对出苗至开花阶段生育期影响最大,对生殖阶段生育期影响较小。在开花期、鼓粒期、结荚期、成熟期,6月15日处理下的根、茎、叶片、叶柄、豆荚及单株植株干物质积累量最高,且随着生育期的延长,干物质分配由营养器官逐渐向生殖器官过渡。大豆产量在6月15日处理达到最高,为3310.27 kg/hm^(2),比早、晚播产量分别提高8.33%和13.66%。因此,大豆品种圣豆24在黄河中下游北岸的适宜种植期为6月15号。A new high-protein soybean variety Shengdou 24 was used as experimental material and treated with three sowing dates(June 5,June 15,June 25).The changes of growth period,dry matter accumulation and distribution and yield of soybean under different sowing date were studied.Results showed that with the delay of sowing date,the total growth period of soybean plant was shortened gradually,especially the growth period from emergence to flowering stage was affected mostly,but the growth period of reproduction stage was less affected.The dry matter accumulation of roots,stems,leaves,petioles,pods and individual plants under June 15 treatment was the highest at flowering,seed bulging,pod setting and maturity stage.With the prolongation of growth stage,the dry matter distribution was gradually transferred from vegetative organs to reproductive organs.The soybean yield under June 15 treatment was 3310.27 kg/hm^(2),which was 8.33%and 13.66%higher than those of early and late sowing,respectively.Therefore,June 15 was the suitable planting date for soybean variety Shengdou 24 on the north bank of the middle and lower reaches of the Yellow River.
