| 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。

| Abstract: | 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 y... |
