摘　　要：研究13种豆科牧草与桉树(Eucalyptus spp.)间作的适应性筛选。结果表明:产草量以GC1581柱花草(Stylosanthes guianensis (Aubl.) Sw. cv. GC1581)最高(376.73 kg/hm2),与其他参试品种间差异极显著(P<0.01);大翼豆(Macroptilium atropurpureum (DC.) Urb.)、有钩柱花草(Stylosanthes hamata (L.) Taub. cv. Verano)和热研12号平托落花生(Arachis pintoi Krapov.et W.C. Greg.)不适合在桉树林间种植;参试品种的抗旱等级相差不大,其中以GC1581柱花草(Stylosanthes guianensis (Aubl.) Sw. cv. GC1581)最耐旱,抗旱等级为1.16;在6龄桉树林间种植豆科牧草,抗病性和抗虫性表现较好。The adaptability of thirteen legumes as intercrop with eucalyptus was evaluated and screened and their survival rate and growth vigor were recorded during the experiment period. The experimental result reveal that Stylosanthes guianensis （Aubl.） Sw. cv. GC1581 had highest yield reaching to 376.73kg/hm^2 which was remarkably different from other legumes （P〈0.01）. Most of the legumes grew well, while Macroptilium atropureum （DC.） Urb. , S. hamata （L.） Taub. cv. Verano, Arachis pintoi Krapov. et W.C. Greg. cv. Reyan No. 12 were not suitable to plant under eucalyptus. The tested varieties showed little discrepancy in drought resistance grade and GC1518 had highest grade （1.16） of drought resistance. Generally, legume had good performance in disease and pest resistance when planted under old eucalyptus.
