To investigate the effects of different postponing nitrogen application treatments on oat grain yield and nitrogen accumulation and translocation, a randomized block design was adopted using two oat varieties Bayou 1 and Dingyou 8 as the experimental materials. Field trial were conducted in 2021 and 2022, and four nitrogen application treatments were set up under a total nitrogen rate of 100 kg·hm-2: all basal application (CK), 1/2 basal application + 1/2 tillering stage fertiliser (N1), 1/2 basal application + 1/2 jointing stage fertiliser (N2), 1/3 basal application + 1/3 tillering stage fertiliser + 1/3 jointing stage fertiliser (N3). The effects of different postponing nitrogen application treatments on yield of oats, dry matter accumulation and translocation in each organ, and nitrogen accumulation and translocation in each organ were determined and analysed. The results indicated that different postponing nitrogen application treatments had an extremely significant impact on oat yield. Compared with CK, the yield of both Bayou 1 and Dingyou 8 significantly increased in N3 treatment, with an average increase rate of 7.96%-8.82% over the two years. However, the yield of oats were reduced by 9.64%-4.50% and 4.12%-6.59% in N1 and N2 treatments respectively, N3 treatment enhanced the pre-anthesis dry matter and nitrogen translocation, post-anthesis dry matter, and nitrogen accumulation, with the increase rate of 21.83%-37.79%, 23.59%-30.19%, 7.58%-12.35%, and 8.48%-11.54%, respectively. Therefore, under a total nitrogen rate of 100 kg·hm-2, applying 1/3 basal application + 1/3 tillering stage fertiliser + 1/3 jointing stage fertiliser better coordinated the nitrogen accumulation and transport of oats, and improved the yield.

为探究不同氮肥后移处理对燕麦籽粒产量及氮素积累转运的影响,采用随机区组设计,以坝莜1号和定莜8号为材料,于2021—2022年连续两年开展大田试验,在总施纯氮量100 kg·hm-2条件下,设置全部基施(CK)、1/2基施+1/2分蘖期追肥(N1)、1/2基施+1/2拔节期追肥(N2)、1/3基施+1/3分蘖期追肥+1/3拔节期追肥(N3)4种氮肥处理,分析不同氮肥后移处理下燕麦产量、各器官干物质和氮素积累转运的差异。结果表明,氮肥后移极显著影响燕麦产量,与CK相比,N3处理下坝莜1号、定莜8号的产量均显著增加,且两年间产量平均增幅为7.96%~8.82%;而N1、N2处理下产量分别较CK降低9.64%~14.50%、4.12%~6.59%;N3处理下燕麦花前干物质、氮素转运量和花后干物质、氮素积累量均增加,增幅分别为21.83%~37.79%、23.59%~30.19%、7.58%~12.35%、8.48%~11.54%。因此,在总施氮量100 kg·hm-2条件下,采用1/3基施+1/3分蘖期+1/3拔节期追肥处理可有效协调燕麦氮素积累与转运,提高籽粒产量。

为探究不同氮肥后移处理对燕麦籽粒产量及氮素积累转运的影响,采用随机区组设计,以坝莜1号和定莜8号为材料,于2021—2022年连续两年开展大田试验,在总施纯氮量100 kg·hm-2条件下,设置全部基施(CK)、1/2基施+1/2分蘖期追肥(N1)、1/2基施+1/2拔节期追肥(N2)、1/3基施+1/3分蘖期追肥+1/3拔节期追肥(N3)4种氮肥处理,分析不同氮肥后移处理下燕麦产量、各器官干物质和氮素积累转运的差异。结果表明,氮肥后移极显著影响燕麦产量,与CK相比,N3处理下坝莜1号、定莜8号的产量均显著增加,且两年间产量平均增幅为7.96%~8.82%;而N1、N2处理下产量分别较CK降低9.64%~14.50%、4.12%~6.59%;N3处理下燕麦花前干物质、氮素转运量和花后干物质、氮素积累量均增加,增幅分别为21.83%~37.79%、23.59%~30.19%、7.58%~12.35%、8.48%~11.54%。因此,在总施氮量100 kg·hm-2条件下,采用1/3基施+1/3分蘖期+1/3拔节期追肥处理可有效协调燕麦氮素积累与转运,提高籽粒产量。

To investigate the effects of different postponing nitrogen application treatments on oat grain yield and nitrogen accumulation and translocation, a randomized block design was adopted using two oat varieties Bayou 1 and Dingyou 8 as the experimental materials. Field trial were conducted in 2021 and 2022, and four nitrogen application treatments were set up under a total nitrogen rate of 100 kg·hm-2: all basal application (CK), 1/2 basal application + 1/2 tillering stage fertiliser (N1), 1/2 basal application + 1/2 jointing stage fertiliser (N2), 1/3 basal application + 1/3 tillering stage fertiliser + 1/3 jointing stage fertiliser (N3). The effects of different postponing nitrogen application treatments on yield of oats, dry matter accumulation and translocation in each organ, and nitrogen accumulation and translocation in each organ were determined and analysed. The results indicated that different postponing nitrogen application treatments had an extremely significant impact on oat yield. Compared with CK, the yield of both Bayou 1 and Dingyou 8 significantly increased in N3 treatment, with an average increase rate of 7.96%-8.82% over the two years. However, the yield of oats were reduced by 9.64%-4.50% and 4.12%-6.59% in N1 and N2 treatments respectively, N3 treatment enhanced the pre-anthesis dry matter and nitrogen translocation, post-anthesis dry matter, and nitrogen accumulation, with the increase rate of 21.83%-37.79%, 23.59%-30.19%, 7.58%-12.35%, and 8.48%-11.54%, respectively. Therefore, under a total nitrogen rate of 100 kg·hm-2, applying 1/3 basal application + 1/3 tillering stage fertiliser + 1/3 jointing stage fertiliser better coordinated the nitrogen accumulation and transport of oats, and improved the yield.
