摘　　要：以"川草2号"老芒麦(Elymus sibiricus L.cv.chuancaoNO.2)为试验材料,采用不同底肥、不同施肥量和不同行距等处理对"川草2号"老芒麦进行种子丰产栽培技术研究,以期为"川草2号"老芒麦种子生产管理技术提供依据。结果表明:复合肥作底肥施肥量为120 kg/hm2的平均种子产量最高,达1 612.26 kg/hm2,施肥量为120 kg/hm2比较适合老芒麦种子生产。施肥量过高,不但浪费资金投入,而且不利于"川草2号"老芒麦种子生产;复合肥作底肥行距为60 cm的种子产量最高,为1 534.5 kg/hm2,在红原进行"川草2号"老芒麦种子生产,行距60 cm比较适合。The advanced technology about seed production of Elymus sibiricus L.cv.chuancaoNo.2 was studied by three treatments （different base fertilizer, different fertilizer amount and different row spacing） in Hongyuan county of Sichuan province. The results as following： when fertilizer amount of base fertilizer being made of compound fertilizer was 120 kg/hm^2, its average seed yield was at most 1612.26 kg/hm^2, but it was suitable to seed production of Elymus sibiricus L.cv. chuancaoNo.2 when the fertilizer amount was 120 kg/hm^2.When compound fertilizer was used as the base fertilizer, the best row spacing was 60cm, accordingly the highest seed yield was 1534.5kg/hm^2, So the suitable row spacing for seed production of Elymus sibiricus L.cv. chuancao No.2in Hongyuan was 60cm.
