本研究以青海省德令哈市种植的10 份耐盐碱燕麦资源为研究材料,对其生产性能、农艺性状以及营养品质进行比较分析,筛选适宜在柴达木盆地推广种植的燕麦(Avena sativa L.)优良品种,缓解海西地区的草畜矛盾.结果表明:10 份燕麦资源的叶生物量分配较低,茎叶比较大,其中青永久402 鲜草产量最高,为77 995kg/hm2,叶重最高,为 0.75g/株,其干草产量和鲜干比也表现良好,分别为15734kg/hm2和4.96;通过灰色关联度分析发现所选11 个指标中株高、穗长和千粒重所占权重较大,这对筛选出适宜该地区的燕麦品种提供了理论基础,所选10 份燕麦资源的加权关联度为:青永久 402>青永久 385>青永久097>青永久219>青永久210>青永久193>青永久280>青永久343>青永久008>青永久238;10 个燕麦资源的粗蛋白含量较低,为9.42%~10.47%;中性洗涤纤维和酸性洗涤纤维含量偏高,分别为53.20%~60.12%和28.60%~34.31%,营养品质较低.
Adaptability evaluation low salt of 10 oat resources in Qaidam Basin
To screen oat(Avena sativa L.)resources suitable for planting in Qaidam Basin and alleviate the contradiction between grass and livestock in Haixi region,10 oat resources were planted in Delingha City,Qinghai Province,and their production performance,agronomic traits,and nutritional quality were compared and analyzed.The results showed as follows:The leaf biomass distribution of the 10 oat resources was lower,and the stem and leaf ratio were larger.QYJ402 had the highest yield(77995 km·hm-2),and the highest leaf weight(0.75g).Hay yield and fresh-dry ratio were also good,which were 15,734 km·hm-2 and 4.96,respectively.Among the 11 indicators selected by grey relational analysis,plant height,ear length,and 1000-grain weight accounted for a greater weight,which played an important role in the comprehensive evaluation of oat resources in this region.The weighted correlation degrees of the selected 10 oat resources were as follows:QYJ 402>QYJ 385>QYJ 097>QYJ 219>QYJ 210>QYJ 193>QYJ 280>QYJ 343>QYJ 008>QYJ 238.The content of crude protein was low(9.42%-10.47%),the content of neutral detergent fiber(53.20%-60.12%)and acid detergent fiber(28.60%-34.31%)were high,and the nutritional quality of the 10 oat resources was poor.The agronomic measures should be improved to improve the forage quality.
