| 中文摘要: |
| 为探索适合河南高产灌区的小麦栽培管理模式，以冬小麦品种平安8号为供试材料，在大田条件下研究了栽培管理模式（农民习惯种植T1、优化管理T2、超高产T3和优化管理T4）对冬小麦花后干物质积累与分配特征及产量的影响。结果表明，4种栽培管理模式下花后各器官干物质积累变化趋势基本一致；与T1相比，超高产和2种优化管理模式增加了花后各营养器官的干物质积累以及干物质在籽粒中的积累量和分配比例；优化管理T2、T4处理主要通过提高花后干物质同化量及其对籽粒的贡献率而获得高产，超高产模式T3主要通过协同提高花前干物质积累量与转运能力和花后干物质同化量及对籽粒的贡献获得高产。在本试验条件下，超高产和2种优化管理模式在小麦灌浆后期35 d均出现了明显的灌浆“小高峰”现象，这是其粒重增加的主要原因。 |

| The objectives of this study were to investigate the effects of different cultivation and management modes on the characteristics of accumulation and distribution of dry matter and the yield of winter wheat cultivar “Pingan 8” after anthesis, therefore, to suggest a reasonable cultivation and management mode in wheat production in Henan high yield irrigation areas. The four different cultivation and management modes were conventional management T1, optimizing management T2, super high yield management T3 and optimizing management T4. The results showed that similar changing trends in dry matter accumulation among various organs after anthesis. Compared with conventional management T1, the accumulation amount in each vegetative organ after anthesis increased in treatments with T2, T3 and T4; nevertheless, its distribution rate significantly or extremely significantly reduced. The accumulation amount and distribution rate of dry matter in grain significantly or extremely significantly increased in treatments withT2, T3 and T4. The two optimizing managements T2 and T4 obtained high yield by increasing the dry matter assimilation amount and contribution to grainfilling after anthesis, the super high yield management T3 could obtain maximum production by improving the accumulation and translocation of dry matter before anthesis, the dry matter assimilation amount and contribution to grain after anthesis. In this study, the super high yield management T3 and the two optimizing managements T2 and T4 got high grain weight due to an obvious filling peak at the late filling stage 35 d. |
