【摘要】 为了解中国燕麦品种生长特性的整体表现,收集了近年来国内燕麦主产区7个燕麦样品,比较了其重要营养组成及品种间的差异,并初步筛选了燕麦优良品种。2014年在山西大同地区,对7种燕麦品种的物候期、株高、分蘖数、产量等考种指标等进行比较研究。综合分析各指标可知,不同燕麦品种在大同试验点的饲草和籽粒产量差异较大,其中‘坝莜13号’籽粒产量为3.22 t/hm~2,与其他品种间差异显著(除‘坝莜14号’外)(P<0.05),最适于进行籽粒生产;‘燕科2号’和‘白燕11号’的干草产量分别为51.96 t/hm~2和49.54 t/hm~2,与其他品种间差异显著(P<0.05),最适于进行饲草生产。更多还原

【Abstract】 In order to understand the overall performance of growth characteristics of oat varieties in China,seven oat varieties were collected from the main domestic oat producing areas, and the superior oat varietieswere selected. The phenological phase, plant height, number of plants, yield and other indexes of the seven oatvarieties in Datong Shanxi were studied in 2014. Comprehensive analysis of various indexes showed that foragegrass and grain yield of different oat varieties in Datong experiment site had great differences, the grain yield of‘bayou No.13’was 3.22 t/hm~2, and had significant difference from that of other varieties(except‘bayouNo.14’)(P<0.05). Therefore,‘bayou No.13’was the most suitable variety for grain production. The hay yieldof‘Yanke No.2’and‘Baiyan No.11’was 51.96 t/hm~2 and 49.54 t/hm~2, respectively, and had significantdifference from that of other varieties(P<0.05), and was the most suitable for forage grass production.更多还原
