摘要： 杜尔伯特扁穗冰草(Agropyron cristatum(L.)Gaertn.cv.Duerbote)是黑龙江省畜牧研究所1994-2008年引种驯化野生新品种。通过三年生产性能的试验研究,结果表明,该品种抗寒、耐旱,适应性强,生长速度快,饲草品质好,牧草产量和种子产量高,干草产量达4215.04 kg/hm2,比对照品种野生扁穗冰草(3271.92 kg/hm2)和细茎冰草(3771.78 kg/hm2)增产28.8%和11.7%。种子平均产量为576.29 kg/hm2,较野生扁穗冰草(428.95kg/hm2)和细茎冰草(557.07kg/hm2)增产34.3%和3.4%,是北方寒冷干旱区种植人工草地、改良天然草地的优质饲草饲料品种。

Abstract: Agropyron cristatum(L.) Gaertn.cv.Duerbote was a new variety which was introduced and domesticated by Heilongjiang Institute of Animal Science from 1994 to 2008.The results from a 3-year study on its productive performance show that Duerbote was characteristic of drought-resistance,cold-resistance,strong adaptability,fast growth rate,good herbage quality,and high forage yield.Its hay yield was 4215.04 kg·hm-2 which was 28.8% higher than that of wild A.cristatum(3271.92 kg·hm-2) and 11.7% higher than that of A.trachycaulum(Link) Malte ex H.F.Lewis(3771.78 kg·hm-2).Its seed yield was 576.29 kg·hm-2 which was 34.3% higher than that of wild A.cristatum(428.95 kg·hm-2) and 3.4% higher than that of A.trachycaulum(557.07 kg·hm-2).In summary,Duerbote could be a good variety choice for artificial grassland planting and natural grassland improvement in cold and arid areas.
