选择国外根蘖型苜蓿润布勒（Rambler）、兰吉兰德（Rangelander）品种和国内育成的综合种4号、5号、6号根蘖型苜蓿，进行生理特性及营养动态研究。结果表明，国内育成的根蘖型苜蓿在抗旱、营养成分和生物产量上均优于国外根蘖型苜蓿品种。%The physiological traits and nutrient dynamics of five creeping-rooted alfalfa varieties were studied in this paper. The alfalfa varieties included two abroad materials, Rambler and Rangeland-er, and three domestic cultivated synthetic varieties No.4, No.5, No.6. The results showed that the domestic varieties were better than introduced ones in terms of drought-resistance, nutritional components, and biomass.
