云南北亚热带冬闲田引种优良牧草的灰色关联度分析与综合评价

Relation grade analysis of grey theory and comprehensive evaluation of introduced forage of winter-free farmland in the north of Yunnan subtropics

应用灰色关联度分析法对14个云南省北亚热带冬闲田引种的优良牧草进行了分析与综合评价。结果表明,在云南省北亚热带地区冬闲田引种优良牧草试验中综合性状表现最好的牧草是兰天堂多花黑麦草、海湾多花黑麦草和盛世紫花苜蓿。其次为特高多花黑麦草、游客紫花苜蓿、猎人河紫花苜蓿、邦德多花黑麦草、赛特紫花苜蓿。而牧杰多花黑麦草、劲能多花黑麦草、光叶紫花苕、泰德多花黑麦草、百慕大多花黑麦草和绿浪高黑麦的加权关联度最小,综合性状最差。

Relation grade analysis of grey theory was used to analyze and evaluate 14 introduced forage of the winter-free farmland of the north of Yunnan subtropics. In this introducing and planting experiment Blue Heaven,Gulf and Millennium had the best complex characteristics followed by Tetragold, Eureka, Abundant, Hunter River, and Sitel. Major, Energa, Tandberg, Barmultra, Yunguangzao, and Spring Green had the poorest complex characteristics and with the reference cultivar they had the minimum weighted relevancy.
