摘　　要：为筛选适合云南永德县南亚热带地区“粮改饲”使用的青贮玉米优良品种,在当地引入“曲辰九号”“红单10号”“禾玉88”“西抗18”和“云瑞21”共5个玉米品种,通过田间品种比较和室内营养分析,应用灰色关联度法综合评价各品种的生产性能。结果表明:在当地5个青贮玉米品种均可进行春、夏、秋三季复种。其中,“云瑞21”全年的干草产量高达53461.39 kg·hm^-2,尽管较其他品种的产量优势不显著(P>0.05),但营养指标占有优势,无论单季种植、还是三季连作,其综合生产性能均最高。推荐当地“粮改饲”使用“云瑞21”青贮玉米专用品种。In order to screen out the fine varieties of silage corn suitable for“grain feeding”in the south subtropical region of Yongde County,Yunnan Province,“Qu Chen No.9”,“Hong Dan No.10”,“He Yu 88”,“Xi Kang 18”and“Yun Rui 21”were introduced.Five maize varieties were selected,and the performance of each variety was evaluated by grey correlation method through field comparison and indoor nutrition analysis.The results showed that five silage corns were replanted in spring,summer and autumn,the annual hay yield of“Yun Rui 21”was as high as 53461.39 kg·hm-2,which was not significantly different from other varieties(P>0.05),but the content of nutrient index was dominant.Whether it is single season or three seasons,its comprehensive production performance is the highest.It is recommended to use the“Yun Rui 21”silage corn variety in the local“grain change feed”.
