摘要：

为缓解盐胁迫对菜豆生产的抑制作用、挖掘高效耐盐促生微生物资源，本研究旨在从盐碱地菜豆根际土壤中筛选出盐胁迫下可促进菜豆幼苗生长的耐盐促生菌，为研制菜豆耐盐微生物菌剂奠定基础。试验以盐碱地菜豆根际土壤及盐极敏感型的菜豆品种‘A18’为试验材料，采用Salkowski比色法等方法筛选菌株并进行盆栽试验验证，对菜豆幼苗生长及生理指标进行测定。结果表明，盐胁迫下菜豆幼苗的根长、地上部鲜重、地上部干重和地下部干重与对照组相比分别下降了49.43%、16.72%、17.07%和25%，接种菌株B10对盐胁迫下菜豆幼苗的促生效果最为显著，与单纯盐胁迫处理相比，盐胁迫下接种了菌株B10的菜豆在根长、地上部鲜重、地下部鲜重、地上部干重和地下部干重分别提高了81.53%、35.12%、37.41%、55.88%和55.56%，皆达到了显著性差异水平。由实验结果可知，耐盐促生菌株B10可显著缓解盐胁迫对菜豆幼苗的伤害，促进生物量积累，具备开发为菜豆专用耐盐微生物菌剂的潜力。本研究为盐碱地菜豆绿色增产提供了优异菌种资源与理论依据，后续可开展菌剂制备与田间应用验证。

Abstract:

This study aimed to screen salt-tolerant plant growth-promoting rhizobacteria from the rhizosphere soil of common bean grown in saline-alkali soil that could enhance the growth of common bean seedlings under salt stress, so as to lay a foundation for the development of salt-tolerant microbial inoculants for common bean. Using the rhizosphere soil of common bean in saline-alkali soil and the salt-sensitive common bean cultivar 'A18' as experimental materials, strains were screened by methods such as the Salkowski colorimetric method, and a pot experiment was conducted for verification. The growth and physiological indices of common bean seedlings were determined. The results showed that under salt stress, the root length, aboveground fresh weight, aboveground dry weight and root dry weight of common bean seedlings decreased by 49.43%, 16.72%, 17.07% and 25%, respectively, compared with the control group. Inoculation with strain B10 exhibited the most significant growth-promoting effect on common bean seedlings under salt stress. Compared with the salt stress treatment alone, inoculation with strain B10 under salt stress increased the root length, aboveground fresh weight, root fresh weight, aboveground dry weight and root dry weight of common bean by 81.53%, 35.12%, 37.41%, 55.88% and 55.56%, respectively, all of which reached significant difference levels. According to the experimental results, strain B10 can promote the growth of common bean seedlings under salt stress and can be further used to develop related salt-tolerant microbial inoculants.
