采用人工胁迫盆栽法,对14种地被植物进行25%海水、50%海水2种胁迫处理,根据植株胁迫处理后的生长表现、盐害指数、盐害率、细胞膜透性等指标进行综合分析,比较耐盐性。结果表明:14种地被植物的耐盐性存在差异,耐盐性可以分为4个等级,其中沙地柏(Sabina vulgaris)、八宝景天(Sedum spectabile)、景天三七(Sedum aizoon)耐盐性最强,马蔺(Iris lactea var.chinensis)、麦冬(Liriope spicata)、五叶地锦(Parthenocissus quinquefolia)、射干(Belamcanda chinensis)较强,金酒吧芒(Miacanthus sinensis‘Gold Bar’)、狼尾草(Pennisetum alopecuroides)、金娃娃萱草(Hemerocallis fulva‘Golden Doll’)、玉带草(Phalaris arundinacea‘Picta’)中等,丰花月季(Rosa cvs)、荷兰菊(Aster novi-belgii)、青绿苔草(Carex leucochlora)最弱。
The 14 kinds of ground cover plants were treated with 25% seawater and 50% seawater by artificial stress potting method. According to the growth performance, salt damage index, salt damage rate, cell membrane permeability and other indicators after plant stress treatment, , More salt tolerance. The results showed that there were differences in salt tolerance of 14 kinds of cover plants, and the salt tolerance could be divided into 4 grades, among which, Sabina vulgaris, Sedum spectabile, Sedum aizoon ) Had the strongest salt tolerance, Iris lactea var. Chinensis, Liriope spicata, Parthenocissus quinquefolia, Belamcanda chinensis, Miacanthus sinensis’Gold Bar Pennisetum alopecuroides, Hemerocallis fulva’Golden Doll ’, Phalaris arundinacea’Picta’ medium, Rosa cvs, Aster novi-belgii, Carex leucochlora is the weakest.
