摘　　要：为了探讨盐碱地区造林绿化中乔灌组合栽植对生长的影响,以提高造林绿化水平,选择了3种乔木(国槐、栾树、合欢)和3种灌木(忍冬、榆叶梅、金银木)进行了组合栽植试验,共设置4种组合(国槐-忍冬、国槐-榆叶梅、栾树-金银木、合欢-金银木),以单独栽植的纯种林为对照,研究了不同组合栽植条件下各树种的植株生长表现.结果表明:乔灌组合栽植与乔木单独栽植相比,乔灌组合栽植的栾树株高和冠幅显著增加、乔灌组合栽植的国槐及合欢株高和冠幅显著降低,茎粗均无显著变化;乔灌组合栽植与灌木单独栽植相比,乔灌组合栽植的榆叶梅的株高和冠幅均显著降低,其叶幕厚度无显著变化;金银木与不同种类的乔木混栽时,其株高和冠幅的差异不具有统计学意义,与合欢混栽的叶幕厚度显著大于与栾树混栽的叶幕厚度.In order to explore the effects of combined planting of tree and shrub on their growth in saline areas and enhance the level of afforestation and landscaping,three tree species（Sophora japonica L.,Koelreuteria paniculata and Albizia julibrissin Durazz）and three shrub species（Lonicera japonica,Prunus trilobaand Lonicera maackii）were used,and four kinds of combinations（S.japonica-L.japonica,S.japonica-P.triloba,K.paniculata-L.maackii and A.julibrissin-L.maackii）were devised,and the growth characteristics of each tree under different combined conditions were investigated.Compared with sole planting of an arbor species,plant height and crown width of K.paniculata significantly increased and those of S.japonica and A.julibrissin significantly decreased when they were planted in combination with shrub species,while the stem diameter showed no significant difference.Compared with sole planting of a shrub species,plant height and crown width of P.triloba significantly decreased,while no conspicuous difference was recorded in its height of leaf canopy.When planted in combination with different arbor species,L.maackii showed no marked difference in its plant height and crown width.When it was planted in combination with A.julibrissin,its height of leaf canopy was substantially greater than when it was planted in combination with K.paniculata.
