| 为揭示小麦耕层优化双行匀播栽培技术的增产机理，通过田间试验，以鲁原502为材料，对旋耕、深耕和耕层优化双行匀播3种耕作技术下冬小麦群体动态、叶面积指数、顶部展开叶光合特性、水分利用效率、生物产量、籽粒产量及其结构进行比较分析。 结果表明，耕层优化双行匀播技术能提高小麦群体分蘖能力及分蘖成穗率，在生育中后期可有效延缓旗叶叶绿素降解，延长光合时间，提高光合强度，维持较高的叶面积指数，促进干物质积累和转化。与深耕、旋耕相比，耕层优化双行匀播技术使小麦灌浆中后期旗叶水分利用效率分别提高了14.12%和19.21%，旗叶光合速率增加了13.33%和25.08%，增产8.11%和13.29%。 |

| In a field experiment, the effects of three different tillage ways of deep tillage, rotary tillage and double row sowing topsoil modification technology (DS TOT) on leaf area index, tillering dynamics, net photosynthesis of the top leaf, leaf water use efficiency (WUEL) and final mass and grain yield of winter wheat were invested. The results showed that DS TOT could alleviate the degradation of flag leaf chlorophyll, and keep higher leaf area index, modify the photosynthetic capacity of flag leaf in longer duration of grain filling, and enhance the final mass and grain yield. Compared with deep tillage and rotary tillage, DS TOT increased final grain yield by 8.11% and 13.29%. WUEL by 14.12% and 19.21%, and the net photosynthesis of flag leaf by 13.33% and 25.08%, respectively. |
