摘要: 为探讨植物根际促生菌用于强化烟草修复Cd污染土壤的可行性,采用盆栽试验,比较了4种根际促生菌剂对烟草吸收和积累Cd的影响。结果表明,4种植物根际促生菌(友益君菌剂、光合细菌菌剂、胶冻样芽孢杆菌菌剂、巨大芽孢杆菌菌剂)均提高了烟草地上部、地下部的Cd含量,并提高了烟草干质量,其中以光合细菌菌剂处理效果最优。相比对照(不加菌处理),施用光合细菌菌剂使烟草地上部、地下部Cd含量分别提高了36.4%、52.4%,使Cd总含量提高了191.2%,同时使烟草地上部、地下部的干质量均提高了100.0%。进一步分析发现,光合细菌菌剂处理提高了土壤有效Cd含量、总氮含量。光合细菌菌剂有望成为用于强化烟草修复Cd污染土壤的有效措施。

Abstract: To explore the feasibility of tobacco remediation of Cd contaminated soil by plant growth promoting rhizobacteria,a pot experiment was conducted to compare the effects of four plant growth promoting rhizobacteria agents (Bacillus gelatinosus,Bacillus megaterium,You Yijun,Phtotsynthetic bacteria)on tobacco uptake and accumulation of Cd.The results showed that,all four plant growth promoting rhizobacteria agents promoted Cd content in the aboveground and underground parts of tobacco,and increased tobacco dry weight.Among them, the photosynthetic bacteria agent had the best effect. Compared to CK(no bacteria addtion treatment),photosynthetic bacteria increased the Cd content in the aboveground and underground parts of tobacco by 36.4%,52.4%,respectively,and increased the total uptake amount of Cd by 191.2%.In addition,it increased dry weight of the aboveground and underground parts of tobacco by 100.0%.Further analysis showed that,photosynthetic bacteria agent increased the available Cd content,and total nitrogen content in soil.In conclusion,photosynthetic bacteria agent is expected to be an important measure to strengthen tobacco-phytoremediation of Cd-contaminated soil.
