摘　　要：采用"3414"最优回归设计,设氮、磷、钾3个因素,4个施肥水平,研究不同施肥水平对秣食豆产量、饲用品质的影响,结果表明,在鼓粒期和N_2P_2K_2(N 40 kg/hm^2,P_2O_570 kg/hm^2,K_2O 50 kg/hm^2)施肥水平下秣食豆饲用品质表现最佳,秣食豆鲜、干草产量最高,分别是39238.09和16209.12 kg/hm^2,较对照分别提高了24.47%、36.17%;粗蛋白、粗脂肪最高,分别为18.40%和2.60%,较对照分别提高了37.02%、73.61%;粗纤维含量最低,较对照降低了18.46%。Using a ＂3414＂ optimal regression design,this study set three factors of nitrogen,phosphorus and potassium and four fertilizer levels（N： 0,20,40,60 kg/ha; P2O5： 0,35,70,105 kg/ha; K2O： 0,25,50,75 kg/ha） to investigate effects on the yield and forage quality of Glycine max.The results showed that during the seed-filling stage and with N2P2K2 fertilizer level（N 40 kg/ha,P2O570 kg/ha,K2O 50 kg/ha）,G.max had the best nutrient quality.At N2P2K2 fertilizer level,the fresh and hay yields were at their highest levels,which were 39238.09 and 16209.12 kg/ha respectively,representing increases of 24.47% and 36.17% compared with the control,crude protein and crude fat content were the highest（18.40% and 2.60%）,37.02% and 73.61% higher than the control respectively.Crude fiber content was the lowest,reducing by 18.46% when compared with the control.
