AI Technical Summary
Technical Problem
Traditional phytoremediation methods are inefficient when dealing with severely cadmium-contaminated areas, and it is difficult for a single method to achieve stable and efficient bioremediation effects.
Method used
The combined repair method of the syringae, arbuscular mycorrhizal fungi and biochar was adopted to form a symbiotic system through co-culture, which significantly reduced the effective cadmium concentration in the soil.
Benefits of technology
It significantly reduces the effective cadmium concentration in the soil, enhances the plant's ability to enrich and fix cadmium, reduces the toxic effect of cadmium on plants, and improves the bioremediation efficiency.

Abstract
According to the method disclosed by the invention, arbuscular mycorrhizal fungi and biochar are added while multiple-leaf goldenrain trees are planted in cadmium-polluted soil. Compared with a traditional remediation mode of independently utilizing plants or microorganisms or biochar, the microorganism-plant-biochar combined remediation has the advantages that the plants, the microorganisms and the biochar are co-cultured to form a symbiotic system, so that the cadmium content in the soil is remarkably reduced, the remediation capacity of the plants is enhanced, and meanwhile, the growth of the plants is remarkably improved. The strategy breaks through the limitation that in the prior art, only improvement of plant resistance is concerned, and the strategy more focuses on the double effects of improving the phytoremediation capacity and promoting the growth effect, so that the maximization of the phytoremediation effect is achieved.
