- 摘要:
- 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。
- Abstract:
- Taking four kinds of gardening Sedum with market potential and two kinds of wild Sedum with the development value as materials,using the methods with the score of appearance drought resistance index,coverage and color,by analyzing the membership function of test data to make a comprehensive evaluation of six kinds of plants under drought and normal management,the six stonecrop plants’drought resistance and adaptability.The results showed that the sequence of drought applicability from strong to weak was,Sedum sarmentosum>Sedum sarmentosum.cv.>Sedum reflexum.cv.>Sedum sexangulare.cv.>Sedum linera.cv.>Sedum polytrichoidis.Under normal management,the result was Sedum sarmentosum>Sedum sarmentosum.cv.>Sedum reflexum.cv.>Sedum linera.cv.>Sedum sexangulare.cv.>Sedum polytrichoidis.To provide the theoretical basis,and promote landscaping application and production in the future.
