摘　　要：应用盆栽试验与大田试验相结合的方法,对从国外引进的3种豆科植物(多年生香豌豆、美丽鹧鸪豆、犹它甜苕子)的抗逆性进行了试验研究。结果表明:美丽鹧鸪豆极耐旱,抗盐碱性能力极强,在盐碱性较大的沟坝地、河滩地,特别是在黄淮海平原的盐碱化土地上均能正常生长,但由于其物候期相当长,在黄土高原地区难以彻底完成其生育期,故从目前情况来看,不宜在该区推广;多年生香豌豆耐旱、耐寒、耐盐碱,抗逆性强,与对照紫花苜蓿相仿,适宜在黄土高原地区推广种植;而犹它甜苕子抗逆性较弱,暂不宜在该区大面积推广,建议在黄土高原西北部地区进行区域试种后小范围内推广。Applying the means of field and potted plant experiment, a study was made to antiadversity of three leguminous plants (Perennial pea, Partridge pea, Utah sweet vetch) introduced from abroad. The result showed that Partridge pea can adapt to drought and salinealkali primely,but it could not finish the growth period completely in Loess Plateau,so it can not be extend to the area now. Perennial pea can adapt to drought, cold and salinealkali. Its antiadversity is sameness with Alfalfas. It should be further extend to Loess Plateau.The antiadversity of Utah sweet vetch is lower than Alfalfas. It should not be extend to the area for a while. 
