摘　　要：为筛选出适宜江淮地区栽培的优良燕麦品种,从物候期、生长特性、产草量和饲用价值4个方面对8份燕麦材料在扬州地区的表现进行了综合评价。结果表明:8份材料平均生长速度呈先下降后上升再下降的趋势。参试燕麦株高128.8~154.4cm,鲜草产量22.87~42.06t/hm^2,干草产量7.63~12.24t/hm^2,种子产量3.88~6.22t/hm^2,茎叶比1.09~4.04,粗蛋白质含量6.6%~12.11%,相对饲用价值82.08~118.5,各项指标均存在显著差异(P<0.05)。采用优势指数法对各项指标进行综合分析,结果表明HY22607和HY22608优势指数明显高于其他材料,比Molasses(对照)高16.65%、15.08%,表现最佳,适宜在南方地区推广利用。In order to select reasonable oat varieties for cultivation in the Jianghuai area,this study evaluated the comprehensive performance of eight oat materials in Yangzhou in terms of four aspects:phenological period,growth characteristics,forage yield and feeding value.The results indicated that the average growth rate of 8 varieties oats decreased first,then increased and then decrease.The plant height was 128~154cm,the fresh yield was 22.87~42.06t/hm 2,the hay yield was 7.63~12.24t/hm 2,the seed yield was 3.88~6.22t/hm 2,the stem leaf ratio was 1.09~4.04,the crude protein content was between 6.6%~12.11%,the relative feed value was 82.08~118.5,there were significant differences in the above indicators(P<0.05).The dominance index method was used to conduct a comprehensive analysis of the various measurement indicators.The results showed that the dominance indexes of HY22607 and HY22608 were significantly higher than other materials,and were 16.65%and 15.08%higher than the control(Molasses),respectively,which showed the best performance and were suitable for utilization and promotion in southern China.
