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/hm~2,比对照品种野生扁穗冰草(3271.92 kg/hm~2)和细茎冰草(3771.78 kg/hm~2)增产28.8%和11.7%.种子平均产量为576.29 kg/hm~2,较野生扁穗冰草(428.95 kg/hm~2)和细茎冰草(557.07kg/hm~2)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.
Study on the Productive Performance of Agropyron cristatum (L.) Gaertn. cv. Duerbote
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 thhan 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.
