Abstract
Remediation using plant-microbe interactions is an efficient and cost-effective technique. However, few studies have reported their effects in phosphate mining wastelands. In this study, two native phosphate-solubilizing microorganisms (PSM) (Trichoderma asperellum LZ1 and Serratia sp. LX2) and two native plants (Lolium perenne L. and Lactuca versicolor) were used to remediate excess phosphorus (P) contamination in phosphate mining wasteland soil. In pot experiments, PSM was found to increase P availability by reducing soil pH. The inoculation of strain LZ1 and LX2 significantly increased the total biomass of L. perenne L. by 41.73%, 6.27%, and 49.26%, respectively. Similarly, L. versicolor biomass also increased by 17.51%, 11.67%, and 41.16%, respectively. In addition, the root, shoot length, and chlorophyll content of L. perenne L. and L. versicolor were also significantly higher than those of the treatments inoculated without PSM. In PSM-inoculated soils, the P accumulation in L. perenne L. and L. versicolor was 11.71 and 5.54 mg/pot, respectively. The findings in this study showed that T. asperellum LZ1 and Serratia sp. LX2 could effectively promote the growth of L. perenne L. and L. versicolor, and increase the P accumulation in plants, which would be beneficial to the phytoremediation of excess P contamination in phosphate mining wasteland.
