| 中文摘要: |
| 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)84.45～91.95 kg/h
m2,施磷量(P2O5)55.65～62.70 kg/hm2,喷施抗旱剂2～3次。 |
| 英文摘要: |
| Five controllable factors are discussed about their effects on yields and yield and quality characters of Ningya No.10 flax in th
e 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. |
