摘  要：
[目的]研究氮磷肥施用量对岷山红三叶草产量和品质的影响。[方法]以岷山红三叶为试材,采用裂区试验设计,施氮肥为主区,设4个水平(0、50、100、150 kg/hm2),施磷肥为副区,设4个水平(0、120、240、360 kg/hm2),分别测定不同氮磷肥料及其组合处理的红三叶草的分枝数、茎叶比(LSR)、干鲜比(DFR)、鲜草和干草的产量。[结果]A2B4(N50 kg/hm2、P2O5360 kg/hm2)处理的红三叶草分枝数最多。获得较高LSR和DFR的N、P肥最佳配比分别为A3B4(N100 kg/hm2、P2O5360 kg/hm2)和A3B1(N 100 kg/hm2、P2O50kg/hm2)。施肥量分别为A2B4(N50 kg/hm2、P2O5360 kg/hm2)和A2B2(N50 kg/hm2、P2O5120 kg/hm2)时,鲜草和干草的产量最高。[结论]P肥施用量对岷山红三叶的草产量和品质无显著影响,N肥施用量对岷山红三叶草产量和品质影响较大。

摘  要：
[Objective] The aim was to study the effect of application rates of nitrogen and phosphorus fertilizers on the yield and quality of Trifolium pratense L.cv.Minshan.[Method] With T.pratense as tested materials,split-plot design was used in the field experiment,in which the main plot was nitrogen application with 4 levels at 0,50,100,150 kg/hm2 and the subplot was phosphorus application with 4 levels at 0,120,240,360 kg/hm2.The branch number,stem-leaf ratio(LSR),dry-fresh ratio(DFR) as well as fresh and hay yield of T.pretense in different treatments of N and P and their combination were determined.[Result] The branch numbers of T.pratense were most in the treatment A2B4(N 50 kg/hm2 + P2O5 360 kg/hm2).The best ratio of N,P fertilizer was A3B4(N 100 kg/hm2 + P2O5 360 kg/hm2) and A3B1(N 100 kg/hm2 + P2O5 0 kg/hm2) resp.,which got a higher LSR and DFR.The fresh and hay yield were the highest when the fertilizer rate was A2B4(N 50 kg/hm2 + P2O5 360 kg/hm2) and A2B2(N 50 kg/hm2 + P2O5 120 kg/hm2) resp.[Conclusion] The application rate of phosphorus fertilizer had no significant effect on the yield and quality of T.pratense,and the application rate of nitrogen fertilizer had great influence on the yield and quality of T.pratense.
