Abstract

Abstract:

【Objective】To explore the effects of different fertilization on the fertility of wheat fields and nitrogen use efficiency and yield of winter wheat in the Huanghuaihai fluvo-aquic soil region in the hope of providing theoretical support and technical guidance for optimizing fertilization measures.【Methods】Based on the 12-year continuous fertilization treatment positioning experiment in Tianjin fluvo-aquic soil area, different fertilization treatments were set: including control (CK), single application of organic fertilizer (M), 50% reduction of chemical fertilizer combined with organic fertilizer (MF₁), conventional quantitative fertilizer combined with organic fertilizer (MF₂) and single application of chemical fertilizer (F).【Results】The results showed that, compared with the control, the fertilization treatments could significantly increase the soil organic matter and available nitrogen, phosphorus and potassium contents in wheat fields, and the combined application of organic and inorganic fertilizers had the best soil fertility improvement effect.Compared with the control, the soil organic matter increased by 92%, 48%, 78% and 20%, respectively in M, MF₁, MF₂.In terms of dry matter accumulation and yield, MF₁ treatment significantly reduced leaf nitrogen content in booting-mature stage, promoted nitrogen transfer to grains, improved nitrogen use efficiency, and significantly increased the number of grains per ear and 1,000-grain weight, thereby increasing yield.The yields of MF₁ and MF₂ treatments reached 6,467and 6,345 kg/hm², respectively, which were 12% and 9% higher than that of treatment F.【Conclusion】In conclusion, the combined application mode of chemical nitrogen fertilizer 115 kg/hm² and organic fertilizer 15,000 kg/hm² can reduce the chemical nitrogen input by 15% compared with the conventional mode, and keep the yield of winter wheat stable, which can be used as a recommended fertilization technology for winter wheat farmland in the fluvo-aquic soil area of the Huanghuaihai Plain.

摘要：

【目的】研究不同施肥方式对黄淮海潮土区麦田肥力和冬小麦氮素利用效率和产量的影响,为该区域优化施肥措施、合理利用有机肥资源和保障作物高产提供理论支持和技术指导。【方法】基于天津潮土区连续12年的施肥处理定位试验,设置施肥处理为对照(CK,不施肥)、单施有机肥(M)、化肥减量50%配施有机肥(MF₁)、常量化肥配施有机肥(MF₂)、单施化肥处理(F)。【结果】与对照相比,施肥处理均能显著提高麦田土壤有机质和碱解氮、速效磷钾含量,且有机无机肥配施处理提升土壤肥力效果最好。与对照相比,M、MF₁、MF₂和F处理土壤有机质增幅分别为92%、48%、78%和20%。MF₁处理孕穗-成熟期叶片氮素含量显著降低,促进氮素向籽粒的转移,提高氮素利用效率,显著提高穗粒数和千粒重,进而起到增产作用。MF₁、MF₂处理冬小麦产量分别达到6 467和6 345 kg/hm²,较F处理提高12%和9%。【结论】施用化肥115 kg/hm²、有机肥15 000 kg/hm²的配施模式能够较常规模式降低化肥投入15%,并保持冬小麦产量稳定,可作为黄淮海平原潮土区冬小麦农田的推荐施肥技术。
