摘　　要：试验以6个青贮玉米品种为材料,在宁夏固原市原州区采用小区试验,分析不同品种性状、叶面积指数、品质及产量的差异性。结果显示,各品种的株高无显著差异(P>0.05),德育丰568的穗位最高,华亦1204的茎粗、茎秆鲜重、果穗鲜重、雄穗鲜重和叶面积指数最大。各品种的平均鲜草产量无显著差异(P>0.05),德育丰568产量位居第1位,为85.36 t/hm^(2)。各品种的干物质含量差异不显著(P>0.05),科河699的中性洗涤纤维、酸性洗涤纤维、粗蛋白、干物质含量均最高,分别为45.44%、36.54%、10.19%、40.75%,宁单40、种星619、种星618品种之间酸性洗涤纤维含量无显著差异(P>0.05)。研究表明,宁单40、德育丰568可作为该地区主推的粮饲兼用型青贮品种。The experiment utilized six varieties of silage corn as materials and employed a small-plot trial to investigate and analyze the differences in traits,leaf area index,quality,and yield among the different varieties in Yuanzhou District,Guyuan City,Ningxia.The results indicated that there were no significant differences in plant height among the varieties(P>0.05),with Deyu Feng 568 having the highest ear height,and the highest stem diameter,stem fresh weight,fresh weight of maize ear,fresh weight of maize tassel and leaf area index were found in Huayi 1204.The average fresh forage yield of the varieties showed no significant differences(P>0.05),with Deyu Feng 568 leading in yield at 85.36 t/hm^(2).The dry matter content among the varieties was not significantly different(P>0.05),with Kehe 699 having the highest levels of neutral detergent fiber,acid detergent fiber,crude protein,and dry matter content,at 45.44%,36.54%,10.19%,and 40.75%,respectively.There were no significant differences in acid detergent fiber content among Ningdan 40,Zhongxing 619,and Zhongxing 618 varieties(P>0.05).The study indicates that Ningdan 40 and Deyu Feng 568 can be considered as main grain and feed silage varieties in this area.
