- •
CO2, Burkholderia sp. D54 and EDTA can stimulate the growth of ryegrass.
- •
CO2 and Burkholderia sp. D54 exhibited different growth stimulation mechanisms.
- •
CO2, rhizobacterium and EDTA decreased the shoot contents of most heavy metals.
- •
However, most treatments enhanced the total accumulating amounts of heavy metals.
- •
CO2 plus rhizobacterium is an optimal way to enhance phytoextraction efficiency.
