氮磷钾肥配施对旱田大麦农艺性状和产量的影响
Effects of Combined Application of Nitrogen, Phosphorus and Potassium Fertilizer on Agronomic Traits and Yield of Barley in Dryland
摘要
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 significandy 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.关键词
