【摘要】 科尔沁地区作为苜蓿主要产区之一,发挥越来越重要的作用,而越冬和生产持久性是影响该地区苜蓿产业健康可持续发展的主要因素之一。本研究结合当地苜蓿产业生产实践,选择国内外13个品种,通过对比分析苜蓿的株高、生长速率、再生性、产量、返青率及枝条数等指标,以期为该地区规模化的产业发展选择适合的苜蓿品种。综合株高、生长速率、再生性、干重、返青等指标,草原3号表现优异。其中产量性状上(株高、生长速率、再生性、干重)与当地生产中常用国外品种康赛、WL319、苜蓿3010差异不显著,在持久性方面,国内苜蓿品种的返青均早于国外苜蓿品种。草原3号适宜在该地区后续生产中进行推广应用。更多还原

【Abstract】 As one of the main producing areas,the plays an increasingly important role in alfalfa Industry.Overwintering and persistence of production are one of the main factors affecting the healthy and sustainable development of the alfalfa industry in the area.Based on the local production practice,this study selects 13 alfalfa varieties domestic and overseas,and compares and analyzes the plant height,growth rate,regeneration,yield,Grass reviving rate and number of branches of the alfalfa,in order to select large-scale alfalfa production in the region.overall consideration, Medicago varia Martin.cv.Caoyuan No.3 performed well.Medicago varia Martin.cv.Caoyuan No.3 are not significantly different from Concept、WL319、alfalfa 3010 in the yield traits(plant height,growth rate,regenerative,dry weight).In terms of persistence,the domestic alfalfa varieties were earlier than the foreign varieties.Medicago varia Martin.cv.Caoyuan No.3 is suitable for application in the subsequent production of the region.更多还原
