摘　　要：试验采用田间试验的方法,研究氮、磷、钾肥配施对紫花苜蓿饲草产量及微量元素营养的影响。结果表明：氮、磷、钾肥能显著提高紫花苜蓿饲草产量,与未施肥处理相比,施肥处理饲草产量增幅为5.45%-15.01%,且氮、磷、钾肥配施效果显著优于单施能提高紫花苜蓿铁、锰、铜、锌、钼、硼、钴、硒等微量元素的含量和累积量,且氮、磷、钾肥配施效果优于单施 NPK处理最优,显著高于未施肥处理。Experiment was carried out in field to study the effect of N,P and K fertilizer application on the yield and microelement nutrition of alfalfa （Medicago sativa L. ）. The results showed the yield of alfalfa was significantly higher than CK with application of N,P and K fertilizer, the yield increased by 5.45% to 15.01%, and the effect of N,P and K fertilizer application was significantly better than the single fertilizer; The content and accumulating quantity of alfalfa＇s Fe,Mn,Cu,Zn,Mo,B,Co and Se were increased with application of N,P and K fertilizer, and the effect of N,P and K fertilizer application was better than the single fertilizer; The effect was most effective by the treatment of NPK, and was significantly higher than CK.
