Abstract

Abstract:

【Objective】 To reveal the differences in the accumulation, transport and utilization of dry matter and nitrogen in winter wheat at different yield levels, and to provide a theoretical basis for reducing the yield difference and high-yielding cultivation of winter wheat in Xinjiang.【Methods】 The experiment was carried out in military households in Changji from 2018 to 2020 with Xindong 41 as the test material, and referring to the production practice in Xinjiang, different fertilization and cultivation management measures were used to simulate high yield I (SH: ≥9,000 kg/hm²), high-yield Ⅱ (HH: 7,500 kg/hm²~9,000 kg/hm²), farmers (FP: 6,000 kg/hm²~7,500 kg/hm²), basic (CK: ≤4,500 kg/hm²) four yield levels.Meanwhile, differences in nitrogen accumulation and transport, and nitrogen absorption and utilization were studied.【Results】 The results showed that the two-year average yield difference of SH, HH, FP and CK was 6,863.27 kg/hm², 5,496.76 kg/hm², 3,735.73kg/hm².The number of harvested panicles and grains per panicle were as follows: SH>HH>FP>CK, and the 1000-grain weight was as follows: HH>SH>FP>CK.The difference of dry matter accumulation in flowering stage of SH, HH, FP and CK is 11,221.65 kg/hm², 8,220.05 kg/hm², 5,527.81 kg/hm², and the difference in dry matter accumulation in mature stage was 16,026.10 kg/hm², 11,918.25 kg/hm², 7,645.80 kg/hm², with the increase of the yield gap, the dry matter accumulation, pre-flowering dry matter transport, post-flowering dry matter accumulation and contribution to grains increased, and pre-flowering dry matter transport and contribution to grains increased; nitrogen accumulation in vegetative organs and pre-flowering nitrogen transport in flowering and mature stages increased with the increase of yield level.Efficiency and nitrogen partial productivity were lower; correlation analysis showed that grain yield was significantly positively correlated with pre-flowering dry matter transport, post-flowering dry matter accumulation, pre-flowering nitrogen transport, nitrogen demand and nitrogen absorption efficiency was significantly positively correlated with nitrogen partial productivity.【Conclusion】 To reduce the yield difference, cultivation and management measures such as fertilization should be adopted, especially the drip irrigation of phosphorus and potassium fertilizers in the late growth stage with water to increase the accumulation and transport rate of dry matter and nitrogen before flowering, the accumulation of dry matter after flowering, and increase nitrogen.In the technology of suitable harvesting panicle number, synergistically increases the number of grains per panicle and 1000-grain weight.

摘要：

【目的】研究不同产量水平下冬小麦干物质与氮素积累、转运及利用差异,为缩小新疆冬小麦产量差及高产栽培提供理论依据。【方法】试验于2018~2020年2年在昌吉军户进行,以冬小麦品种新冬41号为材料,采用不同施肥和栽培管理措施模拟高产Ⅰ(SH:≥9 000 kg/hm²)、高产Ⅱ(HH:7 500 kg/hm²~9 000 kg/hm²)、农户(FP:6 000 kg/hm²~7 500 kg/hm²)、基础(CK:≤4 500 kg/hm²)4个产量水平,研究不同产量水平冬小麦干物质和氮素积累及转运、氮素吸收利用的差异。【结果】SH、HH、FP的2年产量平均与CK产量差为6 863.27、5 496.76和3 735.73 kg/hm²。收获穗数和穗粒数均表现为SH>HH >FP>CK,千粒重表现为HH>SH>FP>CK。SH、HH、FP与CK的开花期干物质积累量差为11 221.65、8 220.05和5 527.81 kg/hm²,成熟期干物质积累量差为16 026.10、11 918.25和7 645.80 kg/hm²,随着产量差增大,干物质积累量、花前干物质转运量、花后干物质积累量及对籽粒的贡献率增高,花前干物质转运率及对籽粒的贡献率降低;开花期和成熟期营养器官氮素积累量、花前氮素转运量均随着产量水平的提高而提高,产量水平越高,需氮量越大,氮素吸收越高,氮素利用效率及氮肥偏生产力越低;籽粒产量与花前干物质转运量、花后干物质积累量、花前氮素转运量、需氮量及氮素吸收效率呈极显著正相关,与氮肥偏生产力呈显著正相关。【结论】缩小产量差应通过施肥等栽培管理措施,尤其是滴灌条件下生育后期磷钾肥随水滴施,增加花前干物质和氮素积累及转运率、花后干物质积累量,提高氮素吸收效率,在适宜收获穗数技术上,协同提高穗粒数与千粒重。
