摘要
为适应贵州草地畜牧业发展对优良紫花苜蓿品种的需求,运用灰色关联分析,通过单株生物量、粗蛋白含量、株高、叶片数、分枝数、主根长、单株根重、根颈直径、侧根数和茎粗10个生产性能指标对WL903、Magna804、WL525HQ、DAKOTA、Magna GrazeⅡ、C201、IML04、WL343HQ、plato、Magna995、spyder和SECURE 12个紫花苜蓿品种在贵州黔南地区的生产性能进行综合评价。结果表明:紫花苜蓿非秋眠型品种WL525HQ、WL903和Magna804与半秋眠型品种DAKOTA、Magna GrazeⅡ的综合表现好,产量高,品质优,适于在黔南地区种植。紫花苜蓿的综合性能可用粗蛋白含量、单株生物量等10个生产性能指标进行鉴定评价。
The biomass per plant,crude protein content,height,leaf number,branch number,length of main root,root weight per plant,collar diameter,lateral root number and stem diameter of WL903,Magna804,WL525 HQ,DAKOTA,Magna GrazeⅡ,C201,IML04,WL343 HQ,Plato,Magna 995,Spyder and SECURE alfalfa varieties were analyzed by grey correlation analysis in Qiannan Region to evaluate their production performance and to meet the need of good alfalfa varieties for development of grassland livestock husbandry in Guizhou. Results： WL525 HQ, WL903 and Magna804（non-fall dormancy varieties）and DAKOTA and Magna GrazeⅡ（semi-fall dormancy varieties） with good comprehensive performance,high yield and better quality should be cultivated in Qiannan Region.The comprehensive performance of alfalfa varieties can be evaluated by identifying 10 production performance indexes.
