摘　　要：应用五因素二次通用旋转组合设计方法,探讨以盐池为代表的宁中地区在干旱雨养立地条件下宁亚10号胡麻高产优质栽培模型。5个可控栽培因子分别为播量、施农肥量、施氮量、施磷量、抗旱剂,效应因子为胡麻籽粒产量、产量性状以及品质性状。通过模拟选优,胡麻产量高于1 200 kg/hm2、籽粒含油率大于37%、亚油酸含量大于12%的优化栽培方案为：播量46.05-50.85 kg/hm2,施农肥量21.50-24.96 t/hm2,施氮量（纯氮）84.45~91.95kg/hm2,施磷量（P2O5）55.65-62.70 kg/hm2,喷施抗旱剂2-3次。Five controllable factors are discussed about their effects on yields and yield and quality characters of Ningya No.10 flax in the arid rain-fed land in central Ningxia,including sowing rate,farm manure rate,applications of nitrogen,phosphorus and drought-resistant agents,with a five factors quadratic general rotary compose design.A optimized scheme with yields more than 1 200 kg/hm2,oil percentage over 37% and linoleic acid content above 12% is selected by simulating： sowing rate of 46.05 kg/hm2～50.85 kg/hm2, farm manure application of 21.50 t/hm2～24.96 t/hm2,pure nitrogen and phosphorus（P2O5） applications of 84.45 kg/hm2～91.95 kg/hm2 and 55.65 kg/hm2～62.70 kg/hm2,and spraying drought-resistant agent two or three times.
