摘　　要：在应用水稻株型设计系统(Rice Plant Type Design System,RPTDS)进行虚拟实验的基础上,结合在非自然群体中进行的田间实验以及穗重模型,对超级稻沈农265的田间配置方式进行了研究。结果表明:有序群体产量水平受田间配置方式影响较小,在沈阳及其周边地区最优配置方式为南北行向,35 cm×14.3 cm行株距,理论穗重3.32 g;中下部叶片对穗重贡献率高的配置方式理论穗重较高;有序群体的产量水平高于无序群体。因此可通过重塑株型,使光能在群体中相对均匀分布,进而通过促进中下部叶片光合能力的提高而提升产量水平。其中,倒三叶的形态、位置在株型设计中具有重要意义。On the basis of virtual experiment carried out by means of Rice Plant Type Design System（RPTDS）,using modified rice population for field experiment and panicle weight model,the plant pattern for supper high yielding rice Shennong 265 was studied.The result showed that： little effect of plant pattern on the yielding level was found and south-north orientated 35 cm×14.3 cm population showed the greatest panicle weight,3.32 g;populations with good performance of middle lower leaves produced greater panicle weight;ordered plant patterns were better than disordered ones.So,revising the plant type to enhance the photosynthetic ability may promote the yielding level.The third leaf may be very important in plant type design.
