摘要
采用随机区组法,对白燕7号、冀张燕5号和林纳三种皮燕麦,白燕11号、晋燕14号和蒙燕833-1三种裸燕麦的生育期、株高、茎粗等形态指标、产草量等进行了分析。结果表明,因气候因素,裸燕麦都未成熟,生育期要长于皮燕麦,皮燕麦中的冀张燕5号生育期最短,为125d,裸燕麦品种蒙燕833-1鲜草产量达到66699kg/hm2,且显著高于其他燕麦品种(P≤0.05)。这些结果表明,蒙燕833-1和白燕11号,是加工青干草和青贮的好原料,冀张燕5号和白燕7号可作为草籽兼用型品种,适宜在青藏高原地区种植推广。
The growth duration,plant height,stem diameter and yield of three hulled oats and three naked oats varieties(bai yan 7 number,jin zhang yan 5 number,lin na and bai yan 11,jin yan 14 and meng yan 833-1)were analyzed using randomized block design.The results showed the growth duration of hulled oats were higher than naked oats because of climate.The growth duration of jin zhang yan 5 was 125d,which was shower than other oat varieties.Meng yan 833-1 fresh grass yield was 66700.05 kg/ha of naked oat,which were higher than other oat varieties.These results showed Meng yan 833-1 and bai yan 11 varieties were fit for processing hay and ensiling.Jin zhang yan 5 and bai yan 3 varieties were fit for forage combination,which were suitable for promoting in Tibetan plateau.
