摘　　要：玉米是八五三农场的主要农作物之一,为了增加玉米产量,提高经济效益,研究了不同抑制剂用量的稳定性肥料对玉米产量的影响。结果表明:光照充足、积温高、雨水调和的年份,玉米最高产量及最大效益肥料用量、抑制剂品种与用量组合为N-P2O5-K2O=228.0-103.5-84.0+NBPT+DMP(高);春季雨雪偏大,玉米生长季积温低、夏季偏干旱的年份,玉米最大效益肥料用量、抑制剂品种与用量组合为N-P2O5-K2O=180.0-82.8-60.0kg.hm-2+NBPT+DCD(高)。Maize is one of the main crops at 853 Farm. For the purpose of increasing per unit area yield of maize and economic benefit,the effect of the application amounts of stabilized fertilizers added different inhibitors on maize yield Was studied. The results showed：in the year with enough illumination, high accumulation temperature and appropriate rainwater, the combination of fertilizer application amount, inhibitor variety and application amount for the highest maize yield and biggest benefit was N-P2O5-K2 O= 228.0-103.5-84.0 ＋ NBPT ＋ DMP （high）. In the year with snowy and rainy spring, low accumulation temperature in maize growth period and droughty summer, the combination of fertilizer application amount,inhibitor variety and application amount for the highest maize yield and biggest benefit was N-P2 O5-K2O = 180.0-82.8-60. 0 kg · hm^-2 ＋ NBPT ＋ DCD （high）.
