摘要: 【目的】研究旱作条件下,不同氮磷钾配比处理对大麦产量和农艺性状的影响,探讨旱田大麦施肥最佳配比,构建旱田大麦施肥模型,为施肥分区和肥料配方设计提供依据。【方法】旱作条件下,以大麦品种甘啤7号为材料,设氮、磷、钾3个因素、4个水平、14个处理的回归最优设计,进行氮、磷、钾三元二次效应方程拟合。【结果】氮、磷、钾对旱田大麦的增产效果依次为N> K2O >P2O5;旱田条件下,增施氮肥大麦株高、穗长、穗粒数、千粒重和成穗数均有显著变化,增施磷肥大麦千粒重和成穗数变化显著,增施钾肥株高、穗长、小穗数、穗粒数和成穗数均有显著变化;生产上氮磷钾施用量分别控制在95.85、120.6和14.96 kg/hm2以内。【结论】在中低肥力水平条件下,旱田大麦肥料投入中首先考虑氮肥投入,以氮定磷、钾,且N∶P2O5∶K2O比以1∶0.83∶0.02为宜。

Abstract: 【Objective】 To explore the optimal ratio of fertilization to barley, build fertilization model of dry barley and provide the basis for fertilization zoning and fertilizer formula design, we study the effect of different NPK treatments on yield and agronomic traits of barley in the dry conditions.【Method】Under the condition of dry farming, using barley Ganpi No. 7 as the test material, the three elements, two effect equations of nitrogen, phosphorus, potassium were fitted with the optimum design of 3 factors, 4 levels and 14 treatments.【Result】The effects of nitrogen, phosphorus, and potassium on barley yield were N> K2O >P2O5; plant height, panicle length, grains per spike, 1,000-grain weight and panicle number were significantly changed with the growth of nitrogen fertilization in barley, 1,000-grain weight and panicle number in barley fertilizer changed significantly with the increasing of P fertilizer application, and plant height, panicle length, spikelet number, grains per spike and panicle number varied significantly with increasing K fertilizer application under dry condition. The amount of nitrogen, phosphorus and potassium in the production were controlled within 95.85, 120.6 and 14.96 kg/hm2.【Conclusion】Under the low fertility condition, nitrogen inputs should be first considered in fertilizer inputs, phosphorus and potassium are determined by nitrogen; N∶P2O5∶K2O with 1∶0.83∶0.02 is appropriate for barley in dryland.
