【摘要】 本研究对23份高粱种质的饲草利用价值进行了评价。通过观测记录生育期、茎叶鲜重、茎叶干重、分蘖数、株高、茎粗、糖锤度、干物质、粗蛋白、中性洗涤纤维、酸性洗涤纤维以及倒伏情况和感病情况,从农艺性状、饲用品质两方面筛选适宜在我国北方地区种植的饲用高粱种质资源。试验得出高产品种有"MN-3469"、"Sg 5103"、"牛尾巴(芮城)",饲用品质优良品种有"MN-4136"、"散发高粱(新绛)"、"贼不偷高粱(宁陕)"、"YOM-2"、"二稀码"、"黑壳白粘高粱"。更多还原

【Abstract】 This field experiment was conducted to evaluate forage utilization value of 23 sorghum germplasms.These varieties were obtained from National crop germplasm resources database.Growth period,fresh yield,dry yield,tillers,plant height,stem diameter,brix,crude protein,neutral detergent fiber,acid detergent fiber,lodging conditions and stay-green were determined for each germplasm.The results indicated that high production varieties are "MN-3469","Sg 5103" and "Niu wei ba(Rui Cheng)" have high forage production potential,and "MN-4136","Sanfa(Xin Jiang)" and "Zei bu tou sorghum(Ning shan)","YOM-2","Er xi ma","Hekebaizhan sorghum" have higher feeding quality.更多还原
