摘　　要：在科尔沁沙地用紫穗槐(Amorpha fruticosa L.)、胡枝子(Lespedeza bicolor Turcz.)、小叶锦鸡儿(Caragana microphyllaLam.)、灌木状经营的桃叶卫矛(Euonymus bungeanus Maxim.)4种常见饲料灌木开展造林试验,并对各树种的叶水势进行了测定。结果表明,桃叶卫矛的造林成活率最高,最低的是小叶锦鸡儿,桃叶卫矛和小叶锦鸡儿越冬表现较好,但胡枝子和紫穗槐存在较严重的回枝现象;桃叶卫矛的适口性最好;4种树种在各生长季水势变化规律不同,胡枝子的水势在整个生长季节变化比较平稳。Planting experiments of 4 kinds of common feed shrub species（Amorpha fruticosa,Lespedeza bicolor,Caragana microphylla,Euonymus bungeanus）were conducted in Horqin sandy land.Leaf water potential of each species was determined.Result shows that：Euonymus bungeanus Caragana microphylla,which are more adaptive in winter,have the highest lowest survival rate respectively;Lespedeza bicolor Amorpha fruticosa have serious phenomenon of immigrating on twigs;palatability of Euonymus bungeanus is the best;water potential change law of 4 species is different in each growing season;change of water potential of Lespedeza bicolor is smooth in whole growing season.
