摘要
为了进一步确认适宜呼伦贝尔地区燕麦与豌豆混播的最佳混播比例,以燕麦品种青海444和豌豆品种青建1号为材料,研究了不同混播处理对燕麦产量和品质、农艺性状的影响。结果表明:当燕麦与豌豆混播比例为1∶2(M_(1∶2)处理)时,燕麦鲜草产量和干草产量在特泥河试验站和鄂温克试验站均最高,最高鲜草产量为34015.8 kg/hm^(2);株高、穗长和茎粗均有明显提高;粗蛋白含量也最高,达11.57%,显著高于燕麦单播(M_(1∶0)处理);中性洗涤纤维含量比燕麦单播(M_(1∶0)处理)明显降低。因此,呼伦贝尔地区燕麦与豌豆混播的最佳比例为1∶2(M_(1∶2)处理)。
Five mixed-sowing ratios of"Qinghai 444"oat to"Qingjian No.1"feed pea were set to screen out the best ratio for Hulunbuir area through comparing the forage yield,quality and agronomic traits.The results showed that when the mixed-sowing ratio of oat to pea was 1∶2(M_(1∶2)),"Qinghai 444"obtained the highest fresh grass yield and hay yield either at Tenihe Experimental Station or at Ewenke Experimental Station,reaching 34015.8 kg/hm^(2) of fresh grass yield;its plant height,ear length and stem diameter significantly increased;its crude protein content was the highest of 11.57%,significantly superior to oat monosowing(M_(1∶0))(P<0.05),while its neutral detergent fiber content was significantly lower than that of M_(1∶0).Thereforce,the best mixed-sowing ratio of oat to pea in Hulunbuir area is 1∶2.
