摘　　要：[目的]研究不同行距配置下小麦生产与产量形成特点,为小麦生产提供依据。[方法]以高产小麦品种石新828为材料,开展15.0 cm+15.0 cm和16.7 cm+16.7 cm+26.7 cm行距配置研究。[结果]干物质积累量以15.0 cm+15.0 cm处理稍高,而产量以16.7cm+16.7 cm+26.7 cm处理较高。生育前期以叶片干物质的积累量最高,生育后期以子粒干物质的积累量最高。开花前储藏在营养器官的同化物开花后向子粒再分配量和再分配率以15.0 cm+15.0 cm处理较高。开花后干物质同化量对子粒的贡献率以16.7 cm+16.7cm+26.7 cm处理较高。[结论]15 cm+15 cm和16.7 cm+16.7 cm+26.7 cm这2种行距配置均适用于河北平原区当前小麦生产。[Objective] The aim was to study wheat production and yield characteristics under different spacing patterns,and provide basis for wheat production. [Method] With high yield wheat variety Shixin 828 as material,spacing patterns of 15. 0 cm ＋ 15. 0 cm and 16. 7 cm ＋ 16. 7cm ＋ 26. 7 cm were studied. [Result] The results showed that compered two patterns,dry matter accumulation in 15. 0 cm ＋ 15. 0 cm was higher,while the grain yield in 16. 7 cm ＋ 16. 7 cm ＋ 26. 7 cm was higher. The accumulation of dry matter in different organs of wheat,was highest in blade at the early stage and in grain at later stage. The dry matters which stored in vegetative organs before anthesis redistribution to grain after anthesis,treatment of 15. 0 cm ＋ 15. 0 cm was higher. Redistribution rate was higher in 15. 0 cm ＋ 15. 0 cm. The contribution rate of dry matter accumulation after anthesis for grain,treatment of 15. 0 cm ＋ 15. 0 cm was higher. [Conclusion]15. 0 cm ＋ 15. 0 cm and 16. 7 cm ＋ 16. 7 cm ＋26. 7 cm are appropriate for wheat production currently in Hebei plain area.
