Objective To screen indigenous rhizobia with high salt tolerance and plant growth-promoting traits from alfalfa nodules and clarify their phylogenetic status and functional potential, thereby providing strain resources and a theoretical basis for developing localized, efficient alfalfa symbiosis and further addressing the constraints of saline soil on alfalfa production in Inner Mongolia. Methods Indigenous alfalfa rhizobia were collected from six saline-alkali sites in Inner Mongolia via a trapping method. Following isolation and purification, the taxonomic status of the strains was determined by 16S rRNA gene sequencing. The plant growth-promoting functions were evaluated through nodulation tests, along with assays for nitrogen fixation, phosphorus solubilization, potassium solubilization, indole-3-acetic acid (IAA) production, and exopolysaccharide (EPS) content. Seed germination and pot experiments were carried out to evaluate the salt stress-alleviating effect of the target strain. Results A total of 250 strains were isolated, with Sinorhizobium meliloti being predominant (227 strains, 90.8%). Eight efficient nodulating strains (e.g., 1B1Y and 1B2Y) were screened out, all of which possessed nitrogen-fixing and potassium-solubilizing capabilities. Some strains (e.g., 2B3Y and 9B3Y) could solubilize organic phosphorus and produce siderophores. Strain 9B3Y secreted the highest amount of IAA (67.5 mg/L), while 16C1Y produced the highest EPS content (2.684 g/L). Under salt stress (0.4% NaCl), the aboveground fresh weight of alfalfa inoculated with strain 2B3Y increased by 29% compared with that of the saline control, and the strain significantly alleviated the inhibition on seed germination (notably increasing the root length). Conclusion The strains screened out, particularly strain 2B3Y, can effectively mitigate the inhibitory effects of salt stress on alfalfa through nitrogen fixation and the secretion of IAA and EPS. These strains show promise for application in alfalfa production and soil improvement in saline regions of Inner Mongolia.

目的 针对内蒙古盐渍化土壤制约苜蓿生产的问题,从该地区苜蓿根瘤中筛选耐盐能力强、促生效果优的根瘤菌,明确其系统发育地位与功能潜力,为开发本地化苜蓿高效共生结瘤的根瘤菌菌剂提供菌种资源和理论依据。 方法 在内蒙古自治区采集6个不同盐碱区域的土壤,通过捕获法获取土著苜蓿根瘤菌,分离纯化后采用16S rRNA基因序列分析鉴定菌株分类地位;通过结瘤试验、固氮/解磷/解钾能力测定、产吲哚-3-乙酸(indole-3-acetic acid, IAA)与胞外多糖含量检测等评价促生功能;结合种子萌发试验与耐盐盆栽试验测定菌株缓解盐胁迫的效果。 结果 共分离出250株菌株,其中苜蓿根瘤菌(Sinorhizobium meliloti)占90.8% (227株);筛选出8株高效结瘤菌株(1B1Y、1B2Y等),均具备固氮与解钾能力,部分菌株(如2B3Y、9B3Y)可解有机磷、产铁载体;9B3Y的IAA分泌量最高(67.5 mg/L),16C1Y的胞外多糖含量最高(2.684 g/L);在盐胁迫(0.4% NaCl)条件下,2B3Y处理组苜蓿地上部鲜重较盐水对照组增长29%,且显著缓解种子萌发抑制(根长提升明显)。 结论 筛选获得的菌株(尤其是2B3Y)能通过固氮、分泌IAA与胞外多糖等机制有效缓解盐胁迫对苜蓿的抑制作用,有望应用于内蒙古盐渍化土壤的苜蓿生产与土壤改良。

目的 针对内蒙古盐渍化土壤制约苜蓿生产的问题,从该地区苜蓿根瘤中筛选耐盐能力强、促生效果优的根瘤菌,明确其系统发育地位与功能潜力,为开发本地化苜蓿高效共生结瘤的根瘤菌菌剂提供菌种资源和理论依据。 方法 在内蒙古自治区采集6个不同盐碱区域的土壤,通过捕获法获取土著苜蓿根瘤菌,分离纯化后采用16S rRNA基因序列分析鉴定菌株分类地位;通过结瘤试验、固氮/解磷/解钾能力测定、产吲哚-3-乙酸(indole-3-acetic acid, IAA)与胞外多糖含量检测等评价促生功能;结合种子萌发试验与耐盐盆栽试验测定菌株缓解盐胁迫的效果。 结果 共分离出250株菌株,其中苜蓿根瘤菌(Sinorhizobium meliloti)占90.8% (227株);筛选出8株高效结瘤菌株(1B1Y、1B2Y等),均具备固氮与解钾能力,部分菌株(如2B3Y、9B3Y)可解有机磷、产铁载体;9B3Y的IAA分泌量最高(67.5 mg/L),16C1Y的胞外多糖含量最高(2.684 g/L);在盐胁迫(0.4% NaCl)条件下,2B3Y处理组苜蓿地上部鲜重较盐水对照组增长29%,且显著缓解种子萌发抑制(根长提升明显)。 结论 筛选获得的菌株(尤其是2B3Y)能通过固氮、分泌IAA与胞外多糖等机制有效缓解盐胁迫对苜蓿的抑制作用,有望应用于内蒙古盐渍化土壤的苜蓿生产与土壤改良。

Objective To screen indigenous rhizobia with high salt tolerance and plant growth-promoting traits from alfalfa nodules and clarify their phylogenetic status and functional potential, thereby providing strain resources and a theoretical basis for developing localized, efficient alfalfa symbiosis and further addressing the constraints of saline soil on alfalfa production in Inner Mongolia. Methods Indigenous alfalfa rhizobia were collected from six saline-alkali sites in Inner Mongolia via a trapping method. Following isolation and purification, the taxonomic status of the strains was determined by 16S rRNA gene sequencing. The plant growth-promoting functions were evaluated through nodulation tests, along with assays for nitrogen fixation, phosphorus solubilization, potassium solubilization, indole-3-acetic acid (IAA) production, and exopolysaccharide (EPS) content. Seed germination and pot experiments were carried out to evaluate the salt stress-alleviating effect of the target strain. Results A total of 250 strains were isolated, with Sinorhizobium meliloti being predominant (227 strains, 90.8%). Eight efficient nodulating strains (e.g., 1B1Y and 1B2Y) were screened out, all of which possessed nitrogen-fixing and potassium-solubilizing capabilities. Some strains (e.g., 2B3Y and 9B3Y) could solubilize organic phosphorus and produce siderophores. Strain 9B3Y secreted the highest amount of IAA (67.5 mg/L), while 16C1Y produced the highest EPS content (2.684 g/L). Under salt stress (0.4% NaCl), the aboveground fresh weight of alfalfa inoculated with strain 2B3Y increased by 29% compared with that of the saline control, and the strain significantly alleviated the inhibition on seed germination (notably increasing the root length). Conclusion The strains screened out, particularly strain 2B3Y, can effectively mitigate the inhibitory effects of salt stress on alfalfa through nitrogen fixation and the secretion of IAA and EPS. These strains show promise for application in alfalfa production and soil improvement in saline regions of Inner Mongolia.

紫花苜蓿(Medicago sativa L.)作为豆科多年生优质牧草,因其高蛋白含量、强适口性及良好的土壤改良作用,在我国畜牧业发展和生态修复中占据重要地位[1]。内蒙古是我国重要的畜牧业基地,苜蓿种植面积逐年扩大,但其生产常受到土壤盐渍化的严重制约。该地区地处干旱半干旱区,蒸发量远大于降水量,加之不合理的灌溉方式,导致土壤盐渍化问题日益突出,据统计,内蒙古盐渍化土壤面积已超过450万hm2,其中许多地块因盐分过高导致苜蓿种子萌发率降低、幼苗生长受阻、产量大幅下降,严重影响了牧草产业的可持续发展[2]
土壤盐渍化会通过渗透胁迫、离子毒害及氧化损伤等多种途径抑制植物生长,还会破坏根瘤菌与苜蓿的共生关系,干扰结瘤过程,表现为结瘤数量减少、固氮能力下降[3]。其机制主要与根瘤细胞中Na+过量积累及关键离子转运蛋白定位异常有关。传统的物理改良(如深耕松土)和化学改良(如施加改良剂)存在成本高、易造成二次污染等局限[4]。近年来,利用微生物缓解植物盐胁迫的生物修复技术因其环境友好、可持续性强等优势成为研究热点。耐盐促生菌(salt-tolerant plant growth-promoting rhizobacteria, ST-PGPR)可通过多种机制促进盐胁迫下植物的生长,如分泌吲哚-3-乙酸(indole-3-acetic acid, IAA)、赤霉素等植物激素调控植物生理代谢,产生1-氨基环丙烷-1-羧酸(1-aminocyclopropane-1-carboxylic acid, ACC)脱氨酶降低乙烯积累以缓解胁迫,溶解土壤中难溶性磷、钾并固定氮素改善营养供应,还可通过合成胞外多糖、产生抗氧化酶等增强植物的耐盐能力[5]
目前,针对苜蓿根际促生菌的筛选已在新疆、宁夏等盐渍化地区开展了部分研究,筛选出的菌株在实验室条件下表现出一定的耐盐促生效果,但由于土壤微生物的分布具有显著的地域特异性,不同生态环境中的菌株其功能特性差异较大[6]。内蒙古地区独特的气候条件(昼夜温差大、冬季寒冷干燥)和土壤类型(多为栗钙土、棕钙土)形成了特殊的根际微生态系统[7],从中筛选出的耐盐促生菌可能具有更适应本地环境的功能优势,但其相关研究仍较为匮乏。
本研究以内蒙古盐渍化土壤中生长的苜蓿根瘤为材料,分离筛选具有高效耐盐能力和促生特性的根瘤菌资源,明确其分类地位及促生潜力,旨在为开发适用于当地的微生物菌剂、改良盐渍化土壤、提高苜蓿产量提供优质资源。

从6处采样点各取3份土样(共18份),这些土样基本属于盐碱地范畴。对每份土样进行3组菌种捕获盆栽试验(共54组),采集新鲜苜蓿根瘤样品,利用划线法进行菌落纯化,共计分离纯化菌株250株。其中,包括苜蓿中华根瘤菌(Sinorhizobium meliloti) 227株,占比90.8%;芽孢杆菌(Bacillus sp.) 15株,占比6.0%;其他菌株8株,占比3.2%。所分离菌株中根瘤菌16S rRNA序列之间差异不大,以代表性菌株2B3Y为例构建系统发育树以明确其分类地位,结果显示其属于S. meliloti (图1)。
在缺氮的松本哲良营养液环境中添加不同菌剂,实验分3个批次完成,共计完成200株根瘤菌的结瘤能力测定。在不同批次中分别挑取结瘤能力强且在低氮环境下农艺性状表现稳定的适量菌株进行后续检验,确认8株菌株在结瘤能力、株高、产量等方面表现较好,分别编号为1B1Y、1B2Y、2B3Y、9B3Y、11C1Y、15B1Y、16C1Y、17C2Y (图2),用于后续功能检验。
根据不同氯化钠浓度下种子萌发情况对苜蓿种子的最大耐受能力进行评测。结果表明,随着盐浓度梯度升高,植株的萌发抑制逐渐增强。当种子处于0.4%浓度的氯化钠环境中时,将近半数(50%)种子的萌发受到明显影响(图3),萌发根长低于种子长度,未达到萌发标准[20]
经不同菌株发酵液浸种处理的种子,其萌发指数表现出不同影响(表2)。当种子处于0.4% NaCl的实验组中时,相较于在清水中各项萌发指标均显著下降,发芽势降至70%,发芽率为73.33%,发芽指数为2.45,种子活力指数为5.11,平均根长缩短近半至2.11 cm,表明盐胁迫对苜蓿种子的萌发存在显著抑制作用。接种菌液处理后,2B3Y相较于盐水对照在根长方面表现出显著的促进作用,11C1Y、15B1Y、16C1Y、17C2Y在萌发指标各方面均高于盐水对照组,具有一定的缓解作用。
图4农艺性状数据可知,苜蓿经菌液灌根处理后,其植株的茎粗、地上/地下部鲜重与干重、株高、主根长及结瘤数等农艺性状指标均显著提升。其中,菌株2B3Y等在缓解盐碱胁迫方面表现突出(图4A),可有效在植株根部定殖并形成根瘤(图4B),对苜蓿茎粗、地上部干重、地下部干重及结瘤数等指标具有较为稳定的显著促进效果(图4C)。以地上部鲜重为例,盐水对照组(0.125 g)仅为清水对照组(0.182 g)产量的68.7%,这表明该试验所用盐浓度显著抑制了苜蓿产量;而施加菌液2B3Y组(0.162 g)相较于盐水对照组(0.125 g)增长29.6%,相较于阳性对照ACCC 17512 (0.152 g)、ACCC 17675 (0.158 g)约提升2.5%-6.6%。由此可见,施加菌液有效增强了植株的耐盐性与生长活力,提升了牧草产量。
将获得8株高效结瘤菌株进行各项促生功能检测(表3),结果显示8株菌株均具有固氮能力,在解磷、铁载体产生及次生代谢物分泌等方面存在一定差异。解磷特性方面:2B3Y、9B3Y、11C1Y、15B1Y、16C1Y、17C2Y具备解有机磷能力;所有菌株均无解无机磷能力。解钾特性方面:8株菌株均具有解钾能力。铁载体与酶活性方面:2B3Y、9B3Y、11C1Y、17C2Y可产生铁载体。IAA与胞外多糖方面:各菌株IAA分泌量介于49.0-67.5 mg/L,其中9B3Y最高(67.5 mg/L);胞外多糖含量为0.500-2.684 g/L,16C1Y最高(2.684 g/L)。
目前研究表明与苜蓿共生结瘤的根瘤菌主要分布于SinorhizobiumRhizobiumPararhizobiumShinellaNeorhizobium 5个属的20余个有效种中,其中Sinorhizobium 属内的2种(Sinorhizobium melilotSinorhizobium medicae)为优势核心种,占我国已分离苜蓿根瘤菌的80%-90%,且在不同生态区存在遗传群分化[21]。本研究从内蒙古6个采样点的苜蓿根瘤中分离得到250株细菌分离物,其中根瘤菌(Sinorhizobium meliloti)占比高达90.8%,这可能与内蒙古独特的气候(昼夜温差大、冬季寒冷)和土壤类型(栗钙土、棕钙土)密切相关。已有研究指出,土壤微生物分布具有显著的地域特异性,不同生态环境会筛选出功能适配的菌株[6-7]。本研究中根瘤菌的高占比印证了Sinorhizobium meliloti对内蒙古盐渍化根际微环境的良好适应性,也说明该地区苜蓿根瘤存在稳定的优势根瘤菌种群,为后续筛选高效菌株奠定了资源基础。
与新疆、宁夏等盐渍化地区的研究相比,本研究分离的菌株在促生功能上呈差异化分布。已有研究表明,新疆地区的解磷菌株资源较为丰富[22],而本研究中的8株高效菌株未表现出解无机磷的能力,但都能有效解钾,其中6株(2B3Y、9B3Y等)具有解有机磷的功能。该功能谱为区域专用菌剂的精准开发提供了靶点。
对8株高效结瘤菌株的促生功能测定结果显示,其核心促生机制可归纳为3类。
所有菌株均具备固氮潜力,可与苜蓿形成共生关系,在缺氮盐渍化土壤中与苜蓿共生为宿主提供氮源;同时,全部具备解钾能力,能将土壤中难溶性钾转化为有效钾,缓解盐胁迫下苜蓿的钾离子吸收障碍[5]。此外,部分菌株(如2B3Y)的解有机磷能力可提升土壤有机磷利用率,进一步补充养分。
八株菌株的IAA分泌量在49.0-67.5 mg/L之间,其中9B3Y等分泌量最高。IAA作为关键植物激素,可促进苜蓿根系生长(如主根伸长、侧根增多),增强根系对水分与养分的吸收能力,这也是9B3Y在种子萌发试验中显著提升根长的重要原因[16]
16C1Y的胞外多糖含量最高(2.684 g/L),胞外多糖可在根系表面形成保护膜,减少盐离子渗透与积累,降低离子毒害[5];而2B3Y、9B3Y等菌株产铁载体的特性能增强苜蓿对铁元素的吸收,缓解盐胁迫下的铁缺乏症状,同时提升植株抗氧化能力,减少氧化损伤[15]
耐盐盆栽试验进一步验证了菌株的实际应用价值:在0.4% NaCl胁迫下,2B3Y处理组苜蓿地上部鲜重较盐水对照组增长29.6%,且茎粗、结瘤数等指标均显著提升,说明该菌株能有效缓解盐胁迫造成的产量损失。与当前使用广泛的生产菌株(ACCC 17512、ACCC 17675)相比,2B3Y在根长、地下部鲜重等指标上表现更优,凸显其在促进苜蓿根系发育、增强抗逆性方面的优势,具备开发为本地化菌剂的潜力。
本研究仍存在2点局限:(1) 菌株筛选仅基于实验室与盆栽条件,未开展田间试验验证,实际应用中可能受自然气候(如干旱、低温)影响,需进一步通过田间小区试验评估其稳定性;(2) 对菌株促生机制的研究较浅,仅测定了宏观功能指标,未深入分析关键功能基因的表达特征,难以揭示其分子层面的耐盐促生机制。
未来研究可围绕2方面展开:(1) 以2B3Y为核心菌株开展不同盐渍化程度土壤的田间试验,优化菌剂的施用剂量与方式(如拌种、灌根);(2) 通过基因组测序与转录组分析挖掘菌株的耐盐与促生关键基因,明确其分子机制,为菌株的基因工程改造(如增强耐盐基因表达)提供靶点。
本研究从内蒙古盐渍化土壤的苜蓿根瘤中筛选获得8株高效耐盐促生根瘤菌,其中菌株2B3Y表现最优。该菌株具备固氮、解有机磷、解钾、产铁载体与高IAA分泌能力,能显著缓解0.4% NaCl胁迫对苜蓿种子萌发(提升活力指数、根长)与植株生长(增加地上部鲜重、结瘤数)的抑制作用。该菌株适配内蒙古盐渍化土壤的生态与养分特点,可作为核心菌株开发本地化微生物菌剂,为该地区苜蓿产业可持续发展与盐渍化土壤改良提供重要支撑。
