摘要: 【目的】 研究12种植物萌发期耐盐性,为盐渍化土壤生态恢复选取耐盐碱的多年生草本植物提供参考依据。【方法】 以披碱草、碱茅、扁穗冰草、高冰草、狗牙根、无芒雀麦、紫花苜蓿、沙打旺、红豆草、甘草、苦豆子和草木樨种子为材料,在萌发期用NaCl溶液在0.0%(CK)、0.5%、1.0%、1.5%、2.0%不同浓度下进行盐胁迫处理,测定每种植物的每日发芽数、根长、芽长,计算出植物的相对发芽率、相对发芽指数、相对发芽势、相对伤害率、相对根芽比,并采用隶属函数计算不同植物的耐盐性得分。【结果】 各种植物种子受到盐胁迫抑制,各个生长指标随NaCl浓度的增加呈下降的趋势。12种植物耐盐性得分排列顺序为甘草>高冰草>碱茅>披碱草>苦豆子>扁穗冰草>紫花苜蓿>红豆草>草木樨>无芒雀麦>沙打旺>狗牙根。【结论】 哈密大南湖二矿生态修复区盐碱地生态修复可以优先考虑甘草、高冰草、碱茅、披碱草、苦豆子等多年生草本植物。

Abstract: 【Objective】 provide a reference for the selection of salt tolerant perennial herbs for the ecological restoration of salinized soil. 【Method】 Elymusdahuricus,Puccinelliadistans,Agropyron cristatum, Thinopyrumponticum, Gynodondactylon,Bromusinermis,Medicago sativa,Astragalusadsurgents,Onobrychisviciaefolia,Glycrrnhizauralensis,Sophoraalopecuroides,Melilotusofficinalis were treated with NaCl solution 0.0% (CK), 0.5%, 1.0%, 1.5%, 2.0% under salt stress. The daily germination number, root length and bud length of each plant were measured, and the relative germination rate, relative germination index, relative germination potential, relative injury rate and relative root bud ratio were calculated. The membership function formula was used to calculate the salt tolerance score. 【Result】 All kinds of plant seeds were inhibited by salt stress, and the inhibition of each growth index showed a downward trend with the increase of concentration. The final score of salt tolerance of 12 plants was ranked in the following order: Glycyrrhizauralensis>Thinopyrumponticum>Puccinelliadistans>Elymusdahuricus>Sophoraalopecuroides>Agropyroncristatum>Melilotusofficinalis>Medicago sativa >Onobrychisviciaefolia>Bromusinermis>Astragalusadsurgens>Cynodondactylon.. 【Conclusion】 In the second mine ecological restoration area of Danan Lake in Hami,Glycyrrhizauralensis, Thinopyrumponticum, Puccinelliadistans, Puccinelliadistans, Elymusdahuricus, and other perennial herbs be given priority.

Key words: NaCl salt stress; seed germination; perennial herbs; salt tolerance
