摘　　要：试验为筛选出适宜黑龙江西部地区种植的青贮玉米品种,采用隶属函数法对28个参试品种的农艺性状、生物量和营养品质进行了综合评价。结果表明,株高最高的是豫青贮23,为340.10 cm;穗位最高的是奥玉青贮5102,为161.60 cm;干草产量最高的是M115S,为25724.23 kg/hm^(2)。28个参试品种的粗蛋白、淀粉、酸性洗涤纤维、中性洗涤纤维含量分别介于6.75%~9.21%、17.90%~27.99%、20.81%~28.38%和42.86%~56.94%之间。通过隶属函数法综合分析28个青贮玉米主要农艺性状、生物产量和营养品质,结果表明,蒙青贮266、M114D、北青贮1号、豫青贮23和中单青贮29的各性状指标在黑龙江西部地区均表现突出,适宜在该地区和气候环境相近的地区推广种植。The study was to select suitable silage maize varieties for planting in the western region of Heilongjiang.The agronomic traits,biomass and nutritional quality of 28 varieties were comprehensively evaluated in this experiment by membership function method.The results showed that the highest plant height was Yu Silage 23,which was 340.10 cm.The highest ear position was Silage 5102,which was 161.60 cm.The highest hay yield was M115S with 25724.23 kg/hm^(2).The crude protein,starch,acid detergent fiber and neutral detergent fiber contents of the 28 participating varieties ranged from 6.75%to 9.21%,17.90%to 27.99%,20.81%to 28.38%and 42.86%to 56.94%.Comprehensive analysis of 28 major agronomic traits,biological yield and nutritional quality of silage maize by the subordinate function method showed that Meng Silage 266,M114D,Bei Silage 1,Yu Silage 23,and Zhongdan Silage 29 were outstanding in the western Heilongjiang region,and were suitable for popularization of planting in this region and areas with similar climatic environments.
