Abstract

Key words: Sowing, Alfalfa(Medicago sativa L.), Root system

摘要： 苜蓿(Medicago sativa)大部分栽培品种的根系为直根型,由主根和侧根组成.在排水良好、土层深厚、湿润的地方,第1年主根可延伸至土表下1.8 m,第2年至3.6 m,最终可延伸至6.0 m以下(Weaver,1926).其根系可划分为直根型、侧根型、根蘖型和根颈型.苜蓿近地面的根与茎连接部为根颈,由真叶以下的胚轴发育而成.其上能形成大量的芽,可长成地上部茎枝,亦是越冬芽着生的部位.根颈可随生长年限的增加不断加粗和向土中深入.苜蓿根颈是产生分枝的重要部位,直接影响苜蓿生产性能和可持续利用,如再生性、耐寒性、抗旱性和抗病虫害性等都与其密切相关.
