摘要
为筛选适合甘南高寒地区的高产优质饲草品种,本试验从青海省购进 6 个饲用燕麦品种(青海 444、青引 1 号、贝勒、爱沃、野马、甜燕麦)及本地燕麦共 7 个饲用燕麦品种进行品比研究,采用植株性状比较、产草量测定、营养成分比较.结果表明,爱沃和青引 1 号的鲜草产量、干草产量、株高为最大,分别为 58 000 kg/hm2、16 380 kg/hm2、156.00 cm和 56 800 kg/hm2、16 260 kg/hm2、151.50 cm;甜燕麦和爱沃的粗蛋白含量最高,分别为 9.26%、9.21%.根据燕麦品种的综合表现得出,引进的 6 个品种燕麦在本试验条件下,生长指标、产量和营养品质综合表现均优于本地品种,其中爱沃、青引 1 号、甜燕麦性状尤为突出,更适宜在甘南高寒地区推广种植.
Abstract
This study aimed to select high-yielding and high-quality oat varieties suitable for the alpine region of Gannan.Seven oat oat varieties,including Qinghai 444,Qingyin 1,Belle,Aiwo,Mustang,Sweet Oats,and local oats,were compared based on plant traits,hay yield,and nutrient content.The study found that Aivo and Qingyin1 had the highest fresh grass yield,hay yield,and plant height,with 58,000 kg/hm2,16,380 kg/hm2,and 156.00 cm,and 56,800 kg/hm2,16,260 kg/hm2,and 151.50 cm,respectively.Sweet Oats and Aivo had the highest crude protein content,with 9.26%and 9.21%,respectively.Based on the comprehensive performance of oat varieties,the six introduced varieties outperformed the local varieties in terms of growth index,yield,and nutritional quality under the conditions of this experiment.Notably,Aiwu,Qingyin 1,and sweet oats exhibited particularly outstanding traits and are therefore more suitable for cultivation in the alpine region of Gannan.It is recommended that these varieties be considered for wider cultivation in the area.
