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/hm2,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/hm2和49.54 t/hm2,与其他品种间差异显著(P<0.05),最适于进行饲草生产。

Abstract: In order to determine the suitable areas for oat (Avena sativa L .) planting, the phonological phase, plant height, number of plants, yield and other index of oat varieties in alpine regions of Shanxi were studied in 2014. Comprehensive analysis of various index shows that different oat varieties in datong sites of forage grass and grain yield difference is bigger, the grain yield of bayou No.14 was 3.22 t/hm2, and other significant difference between varieties (except bayou No.14) (P<0.05), the most suitable for grain production.The hay yield of Yanke No.2 and Baiyan No.11were 51.96 t/hm2 and 49.54 t/hm2, respectively, and other significant difference between varieties(P<0.05), the most suitable for forage grass production.
