摘　　要：为了研究甘引1号黑麦在高寒地区的最佳栽培模式,在天祝县松山镇进行了甘引1号黑麦不同播期试验,记载了甘引1号黑麦的物候期,并测定其农艺性状及种子产量。结果表明:4月17日播种,由于气温较低,甘引1号黑麦出苗迟,草产量与种子产量均较低;4月27日与5月17日播种,甘引1号黑麦出苗正常,生育期短,草产量与种子产量均能得到高产;5月27日与6月9日播种,甘引1号黑麦种子不能成熟。In order to investigate the optimum cultivation model of Secale cereale L.‘ganyin No.1＇in the alpine region,the phenology,the agronomic traits and seed yield of Secale cereale L.‘ganyin No.1＇with different sowing times in the Songshan town of Tianzhu County were recorded. The results showed that because of the low temperature, sowing on April 17 th,the seedling emergence was late,the grass yield and seed yield were lower;the grass yield and seed yield of Secale cereale L.‘ganyin No.1＇sowing on April 27 th and May 17 th were higher;the seed of Secale cereale L.‘ganyin No.1＇sowing on May 27 th and June 9th did not matured.
