摘　　要：采用大田试验的方法,研究了5种氮素水平对山农饲玉7号和农大108两个饲用玉米品种的影响。结果表明,施用氮肥可以提高玉米全株的鲜物质产量和干物质积累量,且能提高饲用玉米的品质,以N4(337.5 kg/hm2)处理效果最佳。In the field experiment, the effects of five nitrogen application levels on yield and quality of different forage maizes SY 7 and ND 108 were studied. The results showed that nitrogen applying could increase the fresh biomass and dry matter accumulation and improve the nutritive quality of forage maizes; the optimum nitrogen application rate for silage quality was 337.5 kg/hm^2.
