【摘要】 以国家审定品种凉山光叶紫花苕和原始群体为对照，在布拖县特木里镇开展了滇东光叶紫花苕新品系的品种比较试验。试验结果表明：滇东光叶紫花苕年均生育周期222.5d，分别比对照原始群体和凉山光叶紫花苕长4d和2.5d；干草产量为12 459.95kg/hm~2，分别比对照原始群体和凉山光叶紫花苕增产14.17%和10.76%；茎叶比为1:1.41，比对照原始群体和凉山光叶紫花苕均小；总体上看滇东光叶紫花苕适应性强、产量高、叶量丰富，适宜在该区域推广。更多还原

【Abstract】 A comparative variety trial was conducted in Butuo County to evaluate Vicia villosa Roth var.glabrescens cv.Diandong line against two controls:Vicia villosa Roth var.glabrescens cv.Liangshan and the original population.The results demonstrated that Vicia villosa Roth var.glabrescens cv.Diandong exhibited an average annual growth cycle of 222.5 days,which was 4 days and 2.5 days longer than the original population and Vicia villosa Roth var.glabrescens cv.Liangshan,respectively.Its dry hay yield reached 12 459.95 kg/hm~2,representing increases of 14.17%and 10.76%compared to the original population and Vicia villosa Roth var.glabrescens cv.Liangshan,respectively.The stem-to-leaf ratio was 1:1.41,which was lower than both the original population and Vicia villosa Roth var.glabrescens cv.Liangshan.Overall,Vicia villosa Roth var.glabrescens cv.Diandong showed strong adaptability,high yield performance,demonstrated high leaf mass production,and is recommended for promotion in the region.更多还原
