摘　　要：采用单因素随机区组试验,在甘肃河西绿洲灌区通过大田试验,研究了矿物质有机肥和化肥配合施用对玉米生产经济效益的影响。结果表明,化肥和矿物质有机肥配合施用对玉米增产效果显著,配施矿物质有机肥600 kg/hm2,化肥施量在当前高施肥水平基础上减量15%时,玉米籽粒的产量为15 783 kg/hm2,增产率2.7%,土地生产率、劳动生产率和成本盈利率均有所提高,而化肥减量水平达到30%时,玉米产量和经济效益指标都呈下降趋势。The test using single factor randomized block design methods to study the effect of the application of mineral organic fertilizer and chemical fertilizer on maize yield and economic benefit at irrigation district in Hexi corridor of Gansu province. The results showed that the mineral organic fertilizer and chemical fertilizer applied together could significantly improve yield of maize. When the mineral organic fertilizer was 600 kg/hm^2, the amount of chemical fertilizer was decreased 15% in the current high level basis,the maize yields were 15 783 kg/hm^2, the increase rate was 2.7%, the land productivity,labor productivity and the cost profit rate improved,but yield of maize and economic benefit showed a downward trend when amount of fertilizer decreased 30%.
