Abstract 【目的】探索丛枝菌根真菌(AMF)对复合盐胁迫下草莓土壤微生态环境的作用效果。【方法】以‘甜查理’草莓(Fragaria × ananassa Duch.)为研究对象,以NaCl与Na2SO4质量浓度比为1∶1的混合盐模拟盐毒害,分别设置0、50 mmol/L和100 mmol/L共3种混合盐物质的量浓度,每种盐物质的量浓度设置接种与不接种AMF,共6个处理,研究了接种AMF对草莓根际土壤微生物数量和酶活性的影响。【结果】随着盐物质的量浓度增加,草莓植株的盐害指数增高;菌根侵染率随盐物质的量浓度的升高而降低;土壤微生物数量和脲酶、过氧化氢酶、蔗糖酶、淀粉酶活性随着盐物质的量浓度增加均降低。盐胁迫28 d后,3种盐物质的量浓度下接种AMF的草莓盐害指数均比不接种处理有明显降低,分别降低了10.91%、21.12%、23.93%。接种AMF提高了土壤脲酶、过氧化氢酶、蔗糖酶、淀粉酶活性以及微生物数量(P<0.05)。复合盐胁迫下,微生物数量和酶活性间有显著或极显著的正相关关系,二者与盐害指数均呈显著的负相关关系(P<0.05)。【结论】接种AMF改善了盐分胁迫下土壤微生态环境,有助于提高草莓对盐碱环境的适应性,缓解复合盐胁迫对草莓生长的伤害。
