摘　　要：通过燕麦品种播期、播量、氮肥、磷肥、灌水量6个因素多位级正交试验研究,极差结果分析表明:对燕麦产量影响的因素主次顺序为灌水量>品种>纯N量>施P2O5量>播期>播量。位级结果分析表明,产量最高组合是:A3B2C4D3E5F3,即科燕一号、播期4月13日、播量15kg/667m2、纯N量7.5kg/667m2、P2O515.0kg/667m2、灌水量100m3/667m2(三叶期-拔节期、拔节期-孕穗期、孕穗期-灌浆期)。对品质粗蛋白影响的因素主次顺序为品种>施P2O5量>播期>纯N量>播量>灌水量;对粗脂肪影响的因素主次顺序为品种>播期>施P2O5量>播量>灌水量>纯N量。该试验研究为今后搭配组合提供科学依据。In order to construct oat high-yielding and high-quality cultivation model at northern foot of Yin Shan Mountain in Inner Mongolia,this article used the orthogonal design method to study the relationship between oat yields, quality and main factors of oat cultivation （lines,Sowing date, planting density,Nitrogen Fertilizer,phosphate fertilizer, irrigation quantity）.The result show that The important order of factors to the yield is：irrigation quantity〉lines〉Nitrogen Fertilizer〉phosphate fertilizer〉Sowing date〉planting density.the Optimal Combination is A3B2C4D3E5F3 （lines：Keyan 1,sowing date：April 5,planting density：15kg/mu, Nitrogen Fertilizer：7.5kg/mu,phosphate fertilizer：15.0kg/mu,irrigation quantity：100m^3）.The important order of the factors that affect the crude protein were lines,phosphate fertilizer, Sowing date,nitrogen fertilizer,planting density,irrigation quantity.The important order of the factors that affect the crude fat were lines,sowing date,phosphate fertilizer,planting density,irrigation quantity,nitrogen fertilizer.
