摘要
以8种地被植物为研究对象,测定并比较土壤含水量,叶片相对含水量,叶片自由水、束缚水含量,以此为基础,定量评价8种地被植物的抗旱性。4种地被菊的抗旱性:北京小菊‘、北美黄’北京夏菊、金鸡菊>大花滨菊;4种景天科品种的抗旱性:胭脂红景天>德国景天、八宝景天>费菜。综合比较4种景天科品种的抗旱性强于4种地被菊的抗旱性。
Taking 8 kinds of ground cover plants as study object,soil moisture content;leaf relative water content,the blade free water,bound water content were measured and compared;on these bases,quantitative evaluation was conducted on drought resistance of 8 kinds of ground cover plants.The results showed that sequences of drought resistance of 4 kinds of ground cover chrysanthemum were as follows： Beijing miniature chrysanthemum,＇North American yellow＇,Beijing summer flowering chrysanthemum,Coreopsis basalis Chrysanthemum maximum;sequences of drought resistance of 4 kinds of Crassulaceae were as follows： Sedum spurium Sedum hyridun,Sedum spectabile Sedum k F.Comprehensive comparison showed that drought resistance of 4 kinds of Crassulaceae varieties were better than 4 kinds of ground cover chrysanthemum.
