摘　　要：在田间试验条件下,采用裂区设计方法,研究了不同追肥、不同行距和不同基肥对川草2号老芒麦Elymus sibiricuscv.chuancao No.2生产性能的影响。结果表明:分蘖-拔节期追施120 kg/hm2复合肥可提高老芒麦生产性能;60 cm行距时老芒麦种子产量最高达1 485 kg/hm2,30 cm行距时老芒麦产量最高达10 170 kg/hm2;施180 kg/hm2复合肥较施15 t/hm2牛粪更有利于老芒麦种子生产。The effect of row spacing and fertilizing on productivity of Elymus sibiricus cv. chuancao No. 2 was conducted through field experiment with split plot design. The results showed that the productivity was increased by applying 120 kg compound fertilizer per hectare in tillerring-jointing stage. As for row spacing, 60 cm was the best for seed production （1 485 kg per hectare）, however, 30 cm was the best for forage production （10 170 kg per hectare）. For the base fertilizer, the compound fertilizer with 180 kg per hectare of application rate was better for seed production than 15 t/hm^2 application rate of cattle manure.
