摘要:
以金露梅、银露梅、砂地柏、红花岩黄芪4种地被植物为试材，研究了干旱胁迫处理对土壤含水量及4种地被植物凋萎系数、叶片游离脯氨酸含量以及丙二醛含量等指标的影响。结果表明：干旱胁迫初期苗木外观无明显变化，各树种生长保持旺盛状态，叶片色泽正常。但随水分胁迫的延续，不同种类之间表现出的抗旱性变化的差异较大。综合分析认为，4种地被植物抗旱性由强至弱依次为：砂地柏＞金露梅＞红花岩黄芪＞银露梅。
Abstract:
Taking Potentilla fruticosa L.，Potentilla glabra Lodd.， Sabina vulgaris Ant.，Hedysarum multijugum Maxim four ground cover plants as materials，effect of drought stress on soil moisture and the wilting coefficient，leaf free proline content，MDA content and other indicators of four ground cover plants were studied.The results showed that the appearance of drought stress early seedling had no significant changes，the state of tree growth remain strong，leaf color was normal.But the difference with the continuation of water stress，showing the changes between the different types of drought stress.Comprehensive analysis，four kinds of ground cover plant drought resistance from strong to weak order Sabina vulgaris Ant.>Potentilla fruticosa L.> Hedysarum multijugum Maxim> Potentilla glabra Lodd..
