【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。更多还原

【Abstract】 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.更多还原
