[目的]为植物的抗旱栽培提供依据。[方法]在温室内模拟自然干旱条件,通过测定灰叶铁线莲、柠条、花棒、醉鱼木4种旱生植物幼树叶片的永久萎蔫系数,对其进行抗旱能力比较。[结果]灰叶铁线莲、柠条、花棒和醉鱼木分别在土壤含水量为3.49%、3.59%、3.63%、3.38%时叶片开始萎蔫,在土壤含水量达到1.51%、1.53%、1.68%、1.57%时产生永久萎蔫。说明灰叶铁线莲表现出与其他旱生植物花棒、柠条、醉鱼木相同的耐旱性。[结论]灰叶铁线莲、柠条、花棒和醉鱼木幼树叶片的永久萎蔫系数分别为1.51%、1.53%、1.68%、1.57%,4种植物的耐旱性相近。

[Objective]The paper was to provide reference for cultivation of plant with drought resistance.[Method]With simulation of natural drought conditions in the greenhouse,the permanent wilting coefficients of leaves in four kinds of xerophytic plant seedlings containing Clematis canescens,Caragana intermedia,Hedysarum scoparium and Buddleja alternifolia were measured,and their drought resistances were compared.[Result]When the soil moistures were 3.49%,3.59%,3.63% and 3.38%,the leaves of C.canescens,C.intermedia,H.scoparium and B.alternifolia began to wilt,which produced permanent wilting as the soil moistures were 1.51%,1.53%,1.68% and 1.57%.This indicated that C.canescens showed the same drought resistance with other three plants.[Conclusion]The permanent wilting coefficients of the leaves of C.canescens,C.intermedia,H.scoparium and B.alternifolia were 1.51%,1.53%,1.68% and 1.57%,respectively.The drought tolerance of four kinds of plants was similar.
