摘　　要：对分别种植在雨养区(甘肃会宁)和灌溉区(甘肃武威)的20个青饲玉米(Zea mays)品种乳熟期产量、农艺性状及营养品质进行评定,以期为甘肃不同区域优质青饲玉米品种的筛选及种植提供理论依据。结果表明,种植在灌溉区所有青饲玉米品种的干重均高于雨养区;雨养区‘豫青贮23’的干重最高,较‘晋单73’提高73.28%,灌溉区‘豫玉22’的干重高于其他品种。雨养区‘陇单10号’穗部性状(穗长、穗粗和穗重)较其他品种表现突出(P<0.05),灌溉区‘蜀玉201’表现最突出(P<0.05)。雨养区,‘延科288’的淀粉含量最高,且中性洗涤纤维含量较‘屯玉168’低80.86%,而‘桂青贮1号’的粗蛋白含量高于其他品种;灌溉区,‘晋单73’的淀粉含量则高于其他品种,且中性洗涤纤维的含量较‘利单295’低53.29%,而‘北农青贮208’的粗蛋白含量最高。灰色关联度分析表明,雨养区‘蜀玉201’‘豫玉22’‘延科288’的综合表现最好,适宜在雨养区种植,而灌溉区‘晋单73’‘蜀玉201’的综合表现最好。‘The yield of milking stage,agronomic traits,and nutritional quality of 20 green-feeding maize(Zea mays)varieties planted in rainfed(Huining,Gansu)and irrigated areas(Wuwei,Gansu)were evaluated to provide a theoretical basis for the screening and planting of high-quality green-feeding maize varieties in different regions of Gansu.The dry weight of all green-feeding maize varieties planted in the irrigation area was higher than that of those in rainfed area.The dry weight of‘Yuqingzhu 23’in the rainfed area was the highest and 73.28%higher than that of‘Jindan 73’.The dry weight of‘Yuyu 22’in the irrigation area was higher than that of other varieties.The panicle traits(length,diameter,and weight)of‘Longdan 10’and‘Shuyu 201’were more prominent than those of other varieties(P<0.05)in the rainfed and irrigation area,respectively.In the rainfed area,‘Yanke 288’had the highest starch content and its neutral detergent fiber content was 80.86%lower than that of‘Tunyu 168’,while the crude protein content of‘Guiqingzhu 1’was higher than that of other varieties.In the irrigation area,the starch content of‘Jindan 73’was higher than that of other varieties and the neutral detergent fiber content was 53.29%lower than that of‘Lidan 295’,while the crude protein content of‘Beinongqingzhu 208’was the highest.The grey correlation analysis showed that‘Shuyu 201’,‘Yuyu 22’,and‘Yanke 288’had the best comprehensive performance in the rainfed area and were suitable for planting in the rainfed area.However,the comprehensive performance of‘Jindan 73’and‘Shuyu 201’was the best in the irrigation area.
