Plants-microbial technology has been regarded as a popular and applied new technique for the remediation of cadmium (Cd) polluted soils.
Therefore, a pot experiment was conducted to explore the effect of Serendipita indica ( S. indica) on soybean growth and the soil enzyme activities, pH and Cd chemical fractions in the soil in 0, 3, 6, and 9 mg·kg −1 Cd concentrations.
Results reflected that compared to uninoculated treatment, S. indica inoculation can still enhance the dry weight (66.57%) and shoot length (90.35%) and promote the net photosynthesis rate (72.18%), transpiration ratio (80.73%), and stomatal conductance (119.05%) of soybean under 9 mg·kg −1 Cd stress. Furthermore, the soil pH, phosphatase (116.39%), and catalase (4.17%) activities in the S. indica treatments were increased under 3 mg·kg −1 Cd concentration. Meanwhile, S. indica could shift Cd from exchangeable fraction to other stable fractions, primarily decreased Cd contamination degree/risk in 6 mg·kg −1 Cd concentration.
