摘　　要：试验设密度(A)与肥料(B)二因素三水平研究了施肥量与密度对高油115玉米农艺性状和产量的影响,结果表明:肥料和密度对高油玉米的农艺性状和产量都有显著的影响。其中,密度为52500株/hm2、施肥量为N:360kg/hm2、P2O5:120kg/hm2、K2O:180kg/hm2时各农艺性状表现最好,产量也最高(6876.45kg/hm2)。The factor of density (A) and(B) fertilizer was designed on three levels in the experiment. The results indicated that the density and fertilizer had obvious effects on the agronomic characteristics and yield of high-oil maize 115. When the density was 52500 plants/hm2 and the volume of fertilizer delivery was N of 360kg/hm2, P2O5 of 120kg/hm2, K2O of180kg/hm2, the agronomic characteristics was best and the yield was highest (6876.45 kg/hm2).
