To explore the suitable high-yield and stable-yield cultivation model for the main wheat-producing areas in the Huaihuaihai Plain, this study used the local main variety Jimai 22 as the material and conducted a field experiment in Chengwu County during the winter wheat growing season from 2022 to 2023. The experiment adopted a two-factor design, setting 3 planting densities and 2 nitrogen application levels, totaling 6 treatment combinations, to study their effects on the lodging rate, yield, and its constituent factors of Jimai 22. The results showed that the planting density and nitrogen application level had significant interaction effects on wheat lodging and yield. The treatment of 25×104 plants/667 m2 basic population combined with 18 kg/667 m2 nitrogen fertilizer achieved a balance between high yield and resistance to lodging, with a yield of 525.36 kg/667 m2 and a lodging rate controlled at 8.34%. The study provided theoretical basis and technical support for the high-yield and stable-yield cultivation of wheat in Chengwu County.

为探究黄淮海平原小麦主产区适宜的高产稳产栽培模式,本研究以当地主栽品种济麦22为材料,于2022年—2023年冬小麦生长季在成武县进行了田间试验。试验采用双因素设计,设置3个种植密度与2个施氮水平,共6个处理组合,研究其对济麦22倒伏率、产量及其构成因素的影响。结果表明,种植密度与施氮水平对小麦倒伏及产量具有显著的互作效应,其中25×104株/667 m2基本苗配合18 kg/667 m2氮肥的处理实现了高产与抗倒的协调,产量达525.36 kg/667 m2,倒伏率控制在8.34%。研究结果为成武县小麦高产稳产栽培提供了理论依据和技术支撑。

为探究黄淮海平原小麦主产区适宜的高产稳产栽培模式,本研究以当地主栽品种济麦22为材料,于2022年—2023年冬小麦生长季在成武县进行了田间试验。试验采用双因素设计,设置3个种植密度与2个施氮水平,共6个处理组合,研究其对济麦22倒伏率、产量及其构成因素的影响。结果表明,种植密度与施氮水平对小麦倒伏及产量具有显著的互作效应,其中25×104株/667 m2基本苗配合18 kg/667 m2氮肥的处理实现了高产与抗倒的协调,产量达525.36 kg/667 m2,倒伏率控制在8.34%。研究结果为成武县小麦高产稳产栽培提供了理论依据和技术支撑。

To explore the suitable high-yield and stable-yield cultivation model for the main wheat-producing areas in the Huaihuaihai Plain, this study used the local main variety Jimai 22 as the material and conducted a field experiment in Chengwu County during the winter wheat growing season from 2022 to 2023. The experiment adopted a two-factor design, setting 3 planting densities and 2 nitrogen application levels, totaling 6 treatment combinations, to study their effects on the lodging rate, yield, and its constituent factors of Jimai 22. The results showed that the planting density and nitrogen application level had significant interaction effects on wheat lodging and yield. The treatment of 25×104 plants/667 m2 basic population combined with 18 kg/667 m2 nitrogen fertilizer achieved a balance between high yield and resistance to lodging, with a yield of 525.36 kg/667 m2 and a lodging rate controlled at 8.34%. The study provided theoretical basis and technical support for the high-yield and stable-yield cultivation of wheat in Chengwu County.
