为了研究复合菌群对铅锌胁迫下蓖麻种子萌发的影响,以期为下一步微生物-蓖麻联合修复盆栽实验提供功能菌群和理论基础,从课题组内经菌肥改良后的植物根际土壤中筛选出根际促生菌,与课题组已有的菌株进行平板拮抗实验,优选测序并构建复合菌群。沙培实验考察复合菌群对铅锌胁迫下种子萌发的影响,收获后分别测定其萌发生长指标、扫描其根系形态、测定重金属富集量,并对其结果进行分析。筛选出了具有溶磷能力的真菌L14为尖孢镰刀菌Fusarium oxysporum,且与实验室两株耐性菌HA、J3构建的复合菌群相互无拮抗。该复合菌群接种到基质后,能在高浓度重金属胁迫下有效促进蓖麻种子萌发及幼苗生长,同时促进其...

In order to investigate the effects of lead-zinc resistant microbial consortium on seed germination of Ricinus communis L. which would be used to construct a functional microbial consortium for the further study of Ricinus communis L.-microbial remediation. The screened rhizospheric microorganisms in microbial fertilizer improved rhizosphere soil were carried out a plate antagonism test with the preserved strains in our laboratory for a gene sequence analysis to construct the functional microbial consortium. Moreover, a pot experiment of the seed of Ricinus communis L. under lead-zinc stress w...
