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N2P2K2(N 40 kg/hm2,P2O5 70 kg/hm2,K2O 50 kg/hm2)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/hm2,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%。

Abstract: 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,P2O5 70 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.
