摘　　要：选择国外根蘖型苜蓿Heinrichs、Spreador、Drylander、Rambler、Trek、Roamer和国内育成的“中图”3号、4号根蘖型苜蓿进行营养动态及生理特性研究。结果表明 ,国内育成的根蘖苜型蓿在抗旱耐牧。The nutrient aynamics and physiological traits of some alfalfa varieties with root shoots were comparatively studied.The alfalfa varieties included six introduced external ones,Heinrichs,Spreador,Drylander,Rambler,Trek,Roamer and two domestic cultivated syntnetic varieties,NO.3 and NO.4.The results showed that the domestic varieties were better than introduced ones on the aspects of drought-resistance,grazing-tolerance,nutritional component,and biomass.
