摘要
为丰富环湖地区饲草资源,本试验在青海湖西岸省草原改良试验站通过对8个不同品种资源的小黑麦物候期、鲜重、干重、株高、茎叶比、叶长、叶宽指标开展综合分析。结果表明,中饲1号、中饲2号能够达到乳熟期,中饲2号鲜草产量最高为68250.00 kg/hm^2,干草产量最高的是3297为13829.60 kg/hm^2,1640的干鲜比最大为27.13%,3297株高最高为202.7cm,3241旗叶最宽为17.64mm,1048旗叶最长为26.15cm,综合分析发现,中饲1号、中饲2号作为优质饲草可在环湖地区种植推广。
This experiment comprehensively analyzed the phenological period,fresh weight,dry weight,plant height,stem-to-leaf ratio,leaf length,leaf width,and indicators of sixteen oat varieties in the forage test area of the grassland improvement test station on the west bank of Qinghai Lake.The results show,Only Qingyin 2 can complete the entire fertility period,Qingtian No.1 had the highest yield of fresh grass(68250.00 kg/hm^2),The highest yield of hay was Qingtian 2(17788.60 kg/hm^2),Qingyin No.2 has the largest dry-to-fresh ratio(27.95%),The highest heading stage of 3297 plants(177.35cm)、Flowering period(197.85cm),Qingtian 1 and Qingtian 2 have the widest flag leaves(1.8cm),The longest flag leaves(40.20cm,40.11cm),Comprehensive analysis found,Qingyin 2 is most suitable for planting and promotion in the alpine pastoral area on the west bank of Qinghai Lake,Qingtian No.1 and Qingtian No.2 can be used as forage production and can also be planted.
