以4个园艺景天品种与2种具有开发价值的野生景天为试材,采用外观抗旱指标、盖度及颜色各项评分,通过隶属函数分析试验数据进行综合评价的方法,研究6种景天植物在干旱及正常管理下,其抗旱适应性程度。结果表明:干旱胁迫下,6种景天抗旱适用性由强至弱依次为:野生垂盆草>园艺垂盆草>反曲景天>六棱景天>金叶佛甲草>藓状景天;正常管理条件下,6种景天抗旱适用性由强至弱依次为:野生垂盆草>园艺垂盆草>反曲景天>金叶佛甲草>六棱景天>藓状景天。试验可为景天植物日后园林绿化推广应用及生产提供参考依据。
Using four horticultural cultivars and two wild cultivars with development value as test materials, the methods of analyzing the test data through membership functions were used to evaluate the drought resistance, coverage and color of the cultivars. Six species Drought plants under drought and normal management, drought adaptability. The results showed that under the drought stress, the drought resistance applicability of six Sedum species from strong to weak were as follows: wild sod grass> gardening sibiricus> ardisia maximus> Day; Under normal management conditions, the applicability of six kinds of Sedums to drought from strong to weak were as follows: wild sod> grass sargassum> day. Tests for Sedum plant landscaping in the future to promote the use and production of reference.
