为探寻小麦高产高效栽培管理模式，在河南省禹州市通过田间小区试验，比较了农民习惯模式（T₁）、优化模式（T₂）、超高产栽培管理模式（T₃）、高产高效模式（T₄）对冬小麦花后干物质和氮素累积及转运的影响。结果表明，与T₁处理相比，T₂、T₃和T₄处理的籽粒产量分别增加了15.9%、 31.5% 和25.4%，花后干物质转运量分别增加了82.5%、109.5%和76.6%，氮素转运量分别增加了50.9%、 49.1% 和41.2%。说明通过优化施肥等措施可以提高小麦花前干物质与氮素的累积，且能显著提高花后干物质与氮素的转运量和转运效率，从而提高穗粒数和产量；在4种栽培管理模式中，T₃处理产量最高，但T₄处理更适宜当地推广。

英文摘要:

In order to obtain high yield and high efficiency, four different cultivation and management modes ［conventional management (T₁), optimizing management (T₂), super-high-yield management (T₃), high yield and high efficiency mode(T₄)］ were conducted through field experiment at Yuzhou city of Henan province, and the effect of different fertilization and management modes on accumulation and translocation of dry matter and nitrogen after anthesis of winter wheat were investigated. The results showed that: compared with T₁ treatment, the yield of T₂, T₃ and T₄ treatments was increased by 15.9%, 31.5% and 25.4%, respectively; after anthesis, the amount of dry matter translocation was increased by 82.5%, 109.5% and 76.6%, respectively; and nitrogen transport capacity was increased by 50.9%, 49.1% and 41.2%, respectively. The results showed that the pre-anthesis nitrogen and dry matter accumulation could be improved through the optimization of fertilization management measure accompanied with increasing the post anthesis dry matter and nitrogen translocation amount and rate significantly, so as to improve the grain number and yield.Of the four modes,T₃ had the highest yield,but T₄ was most suitable for local promotion.
