摘　　要：在祁连山高寒牧区祁连县开展8个燕麦(Avena satiua)品种饲草产量和品质研究,以期筛选出适宜种植的优良品种。结果表明:8个参试品种中以白燕7号、丹麦燕麦、加燕2号表现突出,鲜草产量分别为46189,39314和39908 kg.hm^(-2).干草产量分别为16283,13032和121 58 kg·hm;乳熟期粗蛋白含量分别为14.33%,15.30%和17.63%0.粗脂肪含量分别为2.29%,2.45%和2.82%,钙含量分别为0.472%.0.565%和0.499%·磷含量分别为0.1 23%,0.193%和0.1 67%,中性洗涤纤维含量分别为52.16%,50.69%和52.65%,酸性洗涤纤维含量分别为34.32%.32.28%和32.64%。这3个品种均可作为该地区推广的主要品种。Forage yields and qualities of eight oat varieties were investigated in Qilian country located in the alpine pastoral regions of Qilian Mountains.Result showed that the characters of ‘Bai Yan 7’,‘Denmark oat’ and ‘Jiayan 2’ were excellent.The fresh biomass of three oat varieties reached 46189,39314 and 39908 kg· hm-2,and the dry yields were 16283,13032 and 12158 kg · hm-2,respectively.The crude protein content of milk ripening stage was 14.33%,15.30% and 17.63%,and the crude fat content was 2.29%,2.45% and 2.82%.Meanwhile,the Ca contents of three oat varieties at milk ripening stage were 0.472%,0.565% and 0.499%,and the P contents were 0.123%,0.193% and 0.167%,and the NDF contents were 52.160%,50.69 0%and 52.65 0%,and the ADF contents were 34.32%,32.28% and 32.64%,respectively.These species would be promoted as the region＇s main varieties.
