To clarify how sowing method and nitrogen (N) rate regulate dry matter (DM) and nitrogen accumulation, remobilization, and their vertical distribution within a wheat canopy, a split-plot field experiment was conducted in Zhaoxian Experimental Base of Shijiazhuang Academy of Agriculture and Forestry Sciences from 2022 to 2024. A winter wheat cultivar Lunxuan 103 was used as the test material. Two planting methods of uniform tridimensional sowing and conventional strip sowing were set up in the main plot, and four nitrogen application rates of 0, 180, 240 and 300 kg·hm-2 were set up in the subplot. At anthesis and maturity, aboveground organs were sampled by canopy layers at 20 cm intervals from top to bottom (H1-H4) to quantify DM and N accumulation, pre-anthesis remobilization amount and efficiency, and their contributions to grain. The results indicate that compared with conventional row planting, tridimensional uniform sowing significantly increased plant dry weight at anthesis, pre-anthesis DM and nitrogen transport, transport efficiency, and contribution to grain yield, while post-flowering DM, nitrogen accumulation, and contribution to grain yield were somewhat reduced. The allocation ratio of DM and nitrogen to stem and leaf sheath and leaves increased at anthesis, whereas the allocation ratio to spike rachis and glume decreased at maturity. Compared with conventional strip sowing, under uniform tridimensional sowing, the pre-flowering DM and nitrogen transport in stem and leaf sheath of layers H1 to H4 increased by 14.84% and 21.97%, 24.19% and 16.89%, 16.85% and 28.27%, 11.31% and 24.27%, respectively; for leaves, pre-flowering DM and nitrogen transport increased by 33.65% and 17.63%, 16.17% and 10.63%, 28.16% and 8.20%, and 23.81% and 22.57%, respectively. The increase in pre-flowering DM and nitrogen transport efficiency of stem and leaf sheath in different vertical layers under tridimensional uniform sowing compared to conventional strip sowing followed the order H2>H4>H1>H3 and H3>H2>H1>H4, respectively; for leaves, the increase in pre-flowering DM ranked as H3>H1>H4>H2. As nitrogen application increased, grain weight, dry matter transport, and dry matter and nitrogen transport efficiency in both planting methods first increased and then decreased, with the maximum observed under the 240 kg·hm-2 nitrogen application; post-flowering DM accumulation, grain nitrogen accumulation, and nitrogen transport generally showed an upward trend. In summary, uniform tridimensional sowing mainly promotes increases in grain dry weight and nitrogen accumulation by enhancing the redistribution capacity of dry matter and nitrogen in the middle and upper layers (stem and leaf sheath of H2 and H3) and the middle and lower layers (leaves of H3 and H4). Under the conditions of this experiment, 240 kg·hm-2 was the optimal nitrogen application rate.

为明确播种方式与施氮量对小麦群体干物质、氮素积累与再分配及其垂直分布的影响,于2022—2024年在石家庄市农林科学研究院赵县实验基地开展裂区试验,以冬小麦品种轮选103为材料,主区设立体匀播和常规条播,副区设0、180、240和300 kg·hm-24个施氮量,开花期与成熟期对植株地上部按冠层自上而下每隔20 cm分层(H1~H4),测定不同器官干物质与氮素积累、花前转运量及其效率,并分析对籽粒贡献特征。结果表明,与常规条播相比,立体匀播显著提高小麦开花期植株干重、花前干物质和氮素转运量、转运效率及其对籽粒产量和氮素的贡献率,而花后干物质和氮素积累量及其贡献率有所降低;开花期茎秆+叶鞘、叶片的干物质和氮素分配比例增加,成熟期穗轴+颖壳的干物质和氮素的分配比例有所降低。与常规条播相比,立体匀播下茎秆+叶鞘的花前干物质转运量在H1~H4层下分别提高14.84%、24.19%、16.85%和11.31%,氮素运转量分别提高21.97%、16.89%、28.27%和24.27%;叶片花前干物质转运量分别提高33.65%、16.17%、28.16%和23.81%,氮素运转量分别提高17.63%、10.63%、8.20%和22.57%。立体匀播下小麦群体垂直各层的茎秆+叶鞘花前干物质转运效率较常规条播增幅大小表现为H2>H4>H1>H3,氮素转运效率增幅大小表现为H3>H2>H1>H4;各层叶片的花前干物质增幅大小表现为H3>H1>H4>H2。随施氮量的增加,两种播种方式下粒重、干物质转运量、干物质和氮素转运效率均呈先增加后降低的趋势,均在240 kg·hm-2施氮量下最高;花后干物质积累量、籽粒氮素积累量和氮素转运量整体均呈上升趋势。综上分析,立体匀播主要是通过提高中上层(H2和H3层)茎秆+叶鞘及中下层(H3和H4层)叶片干物质与氮素的再分配能力,促进籽粒干重和氮素积累量的增加,本试验条件下240 kg·hm-2为最适施氮量。

为明确播种方式与施氮量对小麦群体干物质、氮素积累与再分配及其垂直分布的影响,于2022—2024年在石家庄市农林科学研究院赵县实验基地开展裂区试验,以冬小麦品种轮选103为材料,主区设立体匀播和常规条播,副区设0、180、240和300 kg·hm-24个施氮量,开花期与成熟期对植株地上部按冠层自上而下每隔20 cm分层(H1~H4),测定不同器官干物质与氮素积累、花前转运量及其效率,并分析对籽粒贡献特征。结果表明,与常规条播相比,立体匀播显著提高小麦开花期植株干重、花前干物质和氮素转运量、转运效率及其对籽粒产量和氮素的贡献率,而花后干物质和氮素积累量及其贡献率有所降低;开花期茎秆+叶鞘、叶片的干物质和氮素分配比例增加,成熟期穗轴+颖壳的干物质和氮素的分配比例有所降低。与常规条播相比,立体匀播下茎秆+叶鞘的花前干物质转运量在H1~H4层下分别提高14.84%、24.19%、16.85%和11.31%,氮素运转量分别提高21.97%、16.89%、28.27%和24.27%;叶片花前干物质转运量分别提高33.65%、16.17%、28.16%和23.81%,氮素运转量分别提高17.63%、10.63%、8.20%和22.57%。立体匀播下小麦群体垂直各层的茎秆+叶鞘花前干物质转运效率较常规条播增幅大小表现为H2>H4>H1>H3,氮素转运效率增幅大小表现为H3>H2>H1>H4;各层叶片的花前干物质增幅大小表现为H3>H1>H4>H2。随施氮量的增加,两种播种方式下粒重、干物质转运量、干物质和氮素转运效率均呈先增加后降低的趋势,均在240 kg·hm-2施氮量下最高;花后干物质积累量、籽粒氮素积累量和氮素转运量整体均呈上升趋势。综上分析,立体匀播主要是通过提高中上层(H2和H3层)茎秆+叶鞘及中下层(H3和H4层)叶片干物质与氮素的再分配能力,促进籽粒干重和氮素积累量的增加,本试验条件下240 kg·hm-2为最适施氮量。

To clarify how sowing method and nitrogen (N) rate regulate dry matter (DM) and nitrogen accumulation, remobilization, and their vertical distribution within a wheat canopy, a split-plot field experiment was conducted in Zhaoxian Experimental Base of Shijiazhuang Academy of Agriculture and Forestry Sciences from 2022 to 2024. A winter wheat cultivar Lunxuan 103 was used as the test material. Two planting methods of uniform tridimensional sowing and conventional strip sowing were set up in the main plot, and four nitrogen application rates of 0, 180, 240 and 300 kg·hm-2 were set up in the subplot. At anthesis and maturity, aboveground organs were sampled by canopy layers at 20 cm intervals from top to bottom (H1-H4) to quantify DM and N accumulation, pre-anthesis remobilization amount and efficiency, and their contributions to grain. The results indicate that compared with conventional row planting, tridimensional uniform sowing significantly increased plant dry weight at anthesis, pre-anthesis DM and nitrogen transport, transport efficiency, and contribution to grain yield, while post-flowering DM, nitrogen accumulation, and contribution to grain yield were somewhat reduced. The allocation ratio of DM and nitrogen to stem and leaf sheath and leaves increased at anthesis, whereas the allocation ratio to spike rachis and glume decreased at maturity. Compared with conventional strip sowing, under uniform tridimensional sowing, the pre-flowering DM and nitrogen transport in stem and leaf sheath of layers H1 to H4 increased by 14.84% and 21.97%, 24.19% and 16.89%, 16.85% and 28.27%, 11.31% and 24.27%, respectively; for leaves, pre-flowering DM and nitrogen transport increased by 33.65% and 17.63%, 16.17% and 10.63%, 28.16% and 8.20%, and 23.81% and 22.57%, respectively. The increase in pre-flowering DM and nitrogen transport efficiency of stem and leaf sheath in different vertical layers under tridimensional uniform sowing compared to conventional strip sowing followed the order H2>H4>H1>H3 and H3>H2>H1>H4, respectively; for leaves, the increase in pre-flowering DM ranked as H3>H1>H4>H2. As nitrogen application increased, grain weight, dry matter transport, and dry matter and nitrogen transport efficiency in both planting methods first increased and then decreased, with the maximum observed under the 240 kg·hm-2 nitrogen application; post-flowering DM accumulation, grain nitrogen accumulation, and nitrogen transport generally showed an upward trend. In summary, uniform tridimensional sowing mainly promotes increases in grain dry weight and nitrogen accumulation by enhancing the redistribution capacity of dry matter and nitrogen in the middle and upper layers (stem and leaf sheath of H2 and H3) and the middle and lower layers (leaves of H3 and H4). Under the conditions of this experiment, 240 kg·hm-2 was the optimal nitrogen application rate.
