Method for screening radionuclide uranium hyperaccumulator through field observation method

The invention relates to a method for screening a radionuclide uranium hyperaccumulator through a field observation method, which comprises the following steps of: performing field investigation and sampling, determining a dominant plant sample and analyzing the dominant plant sample according to the growth condition of uranium pollution project point vegetation, performing field investigation, and collecting the dominant plant sample and a matched soil sample; measuring the total uranium content of the pre-treated dominant plant sample and the matched soil sample; the uranium enrichment coefficient of the dominant plant sample is obtained, and then whether the dominant plant sample is a uranium hyperaccumulator or not is judged. According to the method provided by the invention, potential plant varieties with super-enriched uranium are preliminarily screened out, and the enrichment and transport characteristics of dominant plants are discussed, so that a phytoremediation germplasm resource library is constru
