摘　　要：为探明超高产大豆品种的花荚形成及其时空分布规律。在田间系统地比较了超高产大豆中黄35、新大豆1号、10-124与高产大豆新大豆10号的花荚形成过程及其时空分布的差异。结果表明,中黄35、新大豆1号、10-124具有终花期、始荚期明显推迟,花期和荚期显著延长,开花节数和结荚节数明显增加,开花和结荚高峰期明显后移,单株花数和荚数明显增多的特点;中黄35中部和上部节开花数多,新大豆1号和10-124下部节开花多;中黄35植株下部和中部节的荚数和粒数分布较多,新大豆1号和10-124植株的中部和上部荚数和粒数分布较多。超高产品种开花期和结荚期明显延长、开花和结荚节数增多、开花和结荚高峰期明显后移,且峰值较高。Detailed understanding the space-time distribution of flowers and pods will contribute to ascertain the high-yield mechanism for super-high-yielding soybean.In the current study,three super-high-yielding soybean,including Zhonaghuang35,Xindadou1 and 10-124 were planted in field trail with high-yield soybean Xindadou10 as control.For super-high-yielding soybeans,the time of final flowering and initial podding significantly delayed,the duration of flowering and podding prolonged,and flowers and pods per plant increased.Zhonghuang35 had more flowers in middle and upper nodes,while Xindadou1 and 10-124 had more flowers in lower nodes.The pods and seeds mainly distributed in lower and middle nodes for Zhonghuang35,while in middle and upper nodes for Xindadou1 and 10-124.In conclusion,the prolonged duration and delayed peaking time for flowering and podding,as well as increased nodes with flowers and pods,all contributed to the yield formation of super-high-yielding soybean.
