摘　　要：根据华玉11参加湖北省2010-2011年玉米(Zea mays L.)区域试验及西南地区各级试验的表现情况,利用产量平均值、变异系数、丰产性参数效应值、高稳系数、标准差比数法等方法对其丰产、稳产、适应性进行了综合分析。结果表明,该品种是一个丰产性好、稳定性强、适应性广的玉米杂交种,适宜在西南山区及国内相应生态区域大面积推广种植。同时为探索其高产高效栽培技术模式,采用裂区设计试验,设置施肥量(F)与密度(M)2因素5水平研究了不同施肥水平和种植密度对玉米品种华玉11农艺性状及产量的影响,得出其获得高产(15993 kg/hm^2)的最优密肥组合为密度6.00万株/hm^2、750.0 kg/hm^2复合肥作底肥、450.0 kg/hm^2尿素作追肥(苗肥∶穗肥=1∶2)。According to the data of Hubei provincial regional experiment and productive administration of maize in southwest China,the performance of productivity,stability and adaptability of Huayu 11 was analysed by testing the average yield,variation coefficient,high yield effect value,high stability coefficient,standard deviation method.The results show that Huayu 11 possesses higher yield,more strong stability,wider adaptability,and suitable for planting in southwest China and other corresponding ecological areas.To gain cultivation technique of high yield of Huayu11,the factor of fertilizer amount(F)and density(M)was designed on five levels in this experiment.The scheme for getting yield of 15993 kg/hm^2 was that plant density of 60000 plants/hm^2,750.0 kg/hm^2 of fertilizer as base fertilizer and 450 kg/hm^2 of urea for topdressing(seed fertilizer∶panicle fertilizer=1∶2).
