摘要
针对西藏阿里人工牧草缺乏的问题,以19个燕麦(Avena sativa)引进品种作为研究对象,利用常规分析方法对燕麦的14个性状指标进行测定分析,采用灰色关联度评价方法进行综合评价,筛选适宜阿里地区种植的燕麦种质。结果表明:贝勒2号的干草产量、旗叶长和相对饲草品质最高,分别为7086.49kg/hm^(2)、23.87cm和243.72;青海444的叶宽和茎粗最高,分别为13.54mm和10.00mm;爱沃的叶茎比最高,为0.87;领袖的株高最高,达到99.71cm。19个燕麦品种的分蘖数、穗长、穗宽、穗重、小穗数、粗蛋白含量和粗脂肪含量范围分别为2.2~3.3,10.30~30.99cm,1.83~9.99cm,0.43~1.21g,2.3~6.5,1.68%~3.20%,5.00%~7.35%。灰色关联度分析结果表明,贝勒2、美达、白燕7号和燕王4个品种综合表现良好,适宜在阿里地区作为牧草进行推广种植。
Based on the shortage of artificial forage in Ali area,nineteen oat varieties were assessed.Nutritional traits and agronomic traits were determined and analyzed by conventional analysis,and the comprehensive evaluation was carried out by grey relational analysis method.The results showed that the Baler 2 had the highest hay yield(7086.49kg/ha),the highest flag leaf length(23.87cm)and the highest RFQ(243.72),Qinghai 444 was the highest flag leaf width(13.54mm)and the highest stem diameter(10.00mm),Everleaf had the highest leaf and stem ratio(0.87),Souris was the best in plant height(99.71cm).The ranges of tiller number,spike length,spike width,spikelet number,spikelet weight,crude protein and ether extract contents of different varieties were 2.2-3.3,10.30-30.99cm,1.83-9.99cm,0.43-1.21g,2.3-6.5,1.68%-3.20%and 5.00%-7.35%,respectively.The grey relational analysis results showed that Baler 2,Monida,Baiyan No.7 and Forage plus were more suitable for planting in Ali region.
