摘    要:试验采用二次正交旋转组合设计方法,通过建立数学模型,分析研究了氮、磷及种植密度对旱作地膜玉米产量的效应,结果表明,氮肥效应>种植密度>磷肥,且交互作用十分显着,对产量的贡献幅度可达2.3%~23.9%;并计算出宁南山区正常降雨条件下,地膜玉米获得>9000kg/hm2产量可采用的栽培技术是:施氮量≥198kg/hm2,P2O5量127.5~183kg/hm2,玉米种植密度56500~60600株/hm2.

关 键 词:地膜玉米  产量—因素模式  栽培技术

Abstract:With the 3 factors 5 levels univesal rotation design field experiment on dryland cron with ground plastic film in south Ningxia hilly area, by establishing mathemastical model, this paper analysed the effect of N, Pin put and seeding density (D) for the yield: N D P, and the contribution of coordination effet for the yield: 2.3%-23.9%; and advanced the cultivation technique of cron yield >900kg/hm2 under normal rainfall condition: input of N≥198kg/hm2,P2O5127.5-183kg/hm2 and the seeding density 56 550-60 500 seedling/hm2.
Keywords:cron with ground plastic film  yield-factor model  cultivation technique
