采用田间盆栽试验法,用衡水市区原土配制成含盐量分别为2.2g/kg、3.1g/kg、4.2g/kg、4.9g/kg、6.7 g/kg、10.2 g/kg的栽培土对9种供试植物进行了盐胁迫处理,测定了供试植物的存活率、相对生长量、叶绿素含量及相对含水量等指标,对9种植物的耐盐性进行研究。结果表明:在盐胁迫下,9种植物的存活率、相对生长量、叶绿素含量及相对含水量等指标均呈明显下降趋势,下降程度因种类而异。综合各指标的分析可知,9种植物的耐盐性差异较大,其耐盐性强弱的顺序为:白蜡>国槐>木槿>栾树>冬青卫茅>紫叶李>紫丁香>金叶女贞>楸树。
採用田間盆栽試驗法,用衡水市區原土配製成含鹽量分彆為2.2g/kg、3.1g/kg、4.2g/kg、4.9g/kg、6.7 g/kg、10.2 g/kg的栽培土對9種供試植物進行瞭鹽脅迫處理,測定瞭供試植物的存活率、相對生長量、葉綠素含量及相對含水量等指標,對9種植物的耐鹽性進行研究。結果錶明:在鹽脅迫下,9種植物的存活率、相對生長量、葉綠素含量及相對含水量等指標均呈明顯下降趨勢,下降程度因種類而異。綜閤各指標的分析可知,9種植物的耐鹽性差異較大,其耐鹽性彊弱的順序為:白蠟>國槐>木槿>欒樹>鼕青衛茅>紫葉李>紫丁香>金葉女貞>楸樹。

Nine landscape plants w ere studied to understand their salt tolerance w hen they were treated with the soil from Hengshui urban district in the saltness of 2 .2 ,3 .1 ,4 .2 ,4 .9 , 6 .7 and 10 .2 g/kg .Survival rate ,relative grow th increments ,chlorophyll content and rela‐tive water content in the leaves were measured after the treatments to the potted plants .The results showed that under the salt atress ,the survival rate ,relative growth increments ,chlo‐rophyll content and relative water content of the plants decreased with the salt stress ,but their decreasing degree varied with each plant .According to multiple analysis of the total in‐dexes ,there were significant differences between the tested 9 plants in salt tolerance and the order of salt tolerance of the determined 9 plants was as gollows :Fraxinus chinensis> So‐phora japonica > Hibiscus syriacus > Koelreuteria paniculata > Euonymus japonicus >Prunus cerasifera cv .atropurpurea> Syringa oblata > Ligustrum × Vicaryi > Catalpa bungei .
