Embodiment

[0029] A method of using uranium-cadmium-resistant fungi to strengthen Boluohui to remediate uranium-cadmium compound-contaminated soil. The key is to screen out fungal strains that can tolerate both uranium and cadmium at the same time, and the screening of uranium-cadmium-resistant fungi is mainly based on the ability to uranium and cadmium. The fungal strains with strong enrichment ability were isolated from the root system of Boluo, and then through the uranium and cadmium tolerance test, the strain with the strongest uranium and cadmium resistance was screened out, and the morphological observation and molecular identification were carried out. Strong strains are used in the remediation of uranium-cadmium complex contaminated soil.

[0030] A further technical solution of the present invention is: the method for separating the fungus is: randomly dig up the roots of the fungus growing in a certain uranium tailings reservoir area in the south, shake off the soil at the root...

Abstract

The invention relates to a method for using uranium-cadmium-resistant fungi to strengthen plants to restore uranium-cadmium composite polluted soil. Including isolation, screening and identification of uranium and cadmium resistant fungi Fusarium sp.A‑2, and the use of uranium-cadmium-tolerant fungi Fusarium sp.A‑2 Strengthen Bo Luohui to remediate uranium-cadmium complex contaminated soil. The fungi resistant to uranium and cadmium were identified as Fusarium fungi, and the minimum inhibitory concentrations of uranium and cadmium were 160 mg / L and 160 mg / L. Pot experiments show that in remediation of uranium-cadmium co-contaminated soil, inoculation of uranium-cadmium-tolerant fungi Fusarium The biomass of sp.A‑2 increased by 181.17%, the enrichment of uranium increased by 100.00%, and the enrichment of cadmium increased by 109.09% compared with that of the uninoculated uranium-cadmium-tolerant fungi. . The invention provides a method with low cost, simple operation and good restoration effect for soil compounded with uranium and cadmium pollution.

Description

technical field [0001] The invention relates to the field of phytoremediation of uranium-cadmium composite polluted soil. Specifically, it is a method for strengthening phytoremediation of uranium-cadmium composite polluted soil by using uranium-cadmium-resistant fungi. Background technique [0002] Uranium mining and uranium metallurgy are important ways to cause combined soil uranium and cadmium pollution. In the vicinity of some uranium mining areas and some uranium-contaminated sites, the uranium content per kilogram of soil is as high as tens to hundreds of milligrams, and the cadmium content per kilogram of soil can also reach tens of milligrams. Not only that, the application of phosphorus fertilizer in agriculture is another important way to cause soil uranium and cadmium compound pollution. The remediation of uranium-cadmium-contaminated soil is not only related to the sustainable development of the nuclear industry but also to the safety of human food, and has be...
