摘　　要：通过青贮玉米肥料运筹试验，研究了青贮玉米的施肥量和施肥方式对产量和营养成分的影响。结果表明：雅玉8号适宜的施肥量为285～375kg／hm2，且干物质产量随着施肥量的增加而增加；施用肥量315kg／hm2时，采用重基肥不施穗肥的施肥方式，青贮玉米产量高，营养成分好。Field experiments with silage corn were conducted in order to study the rational fertilizer application to corn field. The results showed that the appropriate fertilizer rate was 285-375 kg/hm2 for the corn cultivar Yayu 8, at which Yayu 8 was high in biological yield and its dry matter production increased with the fertilizer rate increasing; and when the fertilizer rate was 315 kg/hm2, heavy basal fertilizer application without dressing at tasseling stage could gain a high yield and good nutrient contents.
