摘要
以我国北方地区具有一定耐涝和抗旱能力的20种草本植物为试材,采用环境胁迫试验,研究了干旱、水淹、盐溶液、重金属溶液处理对花卉各项生长指标的影响。结果表明:4个不同处理组的花卉株高、冠幅、叶片数量、存活时间相对于对照组均出现极显著(P<0.01)的抑制作用,抑制程度的排序为干旱处理组>水淹处理组>盐溶液处理组>重金属处理组,3个生长指标对不同处理的敏感程度排序为株高>叶片数量>冠幅。多年生花卉和多年生做一年生栽培的花卉相对于一年生花卉对各种环境胁迫具有更强的耐受性。根据花卉在不同环境胁迫下的反应进行了综合评价和筛选,蓝亚麻、婆婆那、花葱等多年生花卉在综合胁迫下受到的抑制最小,最能适应雨水花园极端的环境条件。
Taking 20 kinds of herbaceous plants with drought and flood resistance in northern China as test materials,environmental stresses experiments under drought,flood,salt solution,heavy metal solution were carried on to study the effect of them on test plants.The results showed that in four different treatment groups,plant height,crown,leaf number and survival time presented significantly（P〈0.01）inhibitory effect compared with control group,the inhibition degree sorting was drought treatment group〉flood treatment group〉salt solution treatment group〉heavy metal treatment group,the order of sensitive degree to different treatments of 3growth indexes was plant height〉leaf number〉crown,and annuals as perennial cultivated had stronger resistance to various environmental stresses.Comprehensive evaluation and selection according to the response to different environmental stresses had been carried on,perennials such as Linum perenne,Veronica spicata,and Allium schoenoprasum had been restrained most weakly under the comprehensive stress,and they were the most suitable for the extreme environmental conditions in rain garden.
