试验采用裂区设计方法，研究了不同用量玉米专用肥（史丹利复混肥）及种植密度对春玉米郑单958产量及经济效益的影响，结果表明：春玉米产量随施肥量的增加呈现先升高后降低的趋势，均以A2处理（750kg/ha2）时最高，为15.86 t/ha2；春玉米产量随密度增加呈先增加后降低趋势，种植密度在B3处理（7.5万株/ha2）时产量最高，为16.31 t/ha2；各肥密处理组合纯增产效益以A3B3处理（900 kg/ha2、7.5万株/ha2）最高，A2B3处理（750 kg/ha2、7.5万株/ha2）次之，纯增产效益分别为12600.00元/ha2和12440.00元/ha2；综合产量及效益分析， A3B3处理组合总体表现最佳，可在试验地区推广应用.

Using split plot design, studied the effects of different maize special fertilizer(STANLEY compound fertil-izer) and planting densities on the yield and economic benefit of Spring Maize Zhengdan 958, the results showed that the yield increased at first and then decreased with the increase of fertilization amount, in A2 treatments were the highest (750kg/ha2), 15.86t/ha2; the yield with the increasing of planting density increased at first and then de-creased, in B3 treatments were the highest(7.5million lines/ha2), 16.31t/h2; Refer to the benefit of pure increase yield on density and fertilizer treatment combinations, A3B3 treatment(900kg/ha2,7.5million lines/ha2)was the high-est, A2B3 treatment (750kg/ha2,7.5million lines/ha2) was the second, the benefits of pure increase yield were 12600.00yuan/ha2 and 12440.00yuan/ha2 respectively; A3B3 treatment combination had the best overall perfor-mance in the comprehensive yield and benefit analysis, which could be widely applied in the test area.
