摘要
为筛选出适宜在吴忠市红寺堡区栽植的青贮玉米品种,对比研究了5个青贮玉米品种的生产性能、干物质含量和果穗特性。结果表明:金陵青贮67的株高、穗位高、绿叶数最高;正大12茎粗最高;京科青贮932秃尖最短,干物质含量、鲜草产量、干草产量最高,分别为39.25%、75677.55 kg/hm^(2)、29703.44 kg/hm^(2);京科青贮932、正大12的穗长、穗重显著高于其他品种。综合来看,京科青贮932适宜在吴忠市红寺堡区推广种植。
In order to screen out the silage maize varieties suitable for planting in Hongsibao District of Wuzhong City,a comparative study was conducted on the production performance,dry matter content,and ear characteristics of five silage maize varieties.The results showed that Jinling Qingzhu 67 had the highest plant height,spike height,and green leaf number;Zhengda 12 had the highest stem thickness;Jingke Qingzhu 932 had the shortest barren ear tip,the highest dry matter content(39.25%),the highest fresh grass yield(75677.55 kg/hm^(2)),and the highest dry grass yield(29703.44kg/hm^(2));the ear length and weight of Jingke Qingzhu 932 and Zhengda 12 were significantly higher than other varieties.Overall,Jingke Qingzhu 932 is suitable for promotion and cultivation in Hongsibao District ofWuzhong City.
