Effects of DSE on soil microorganisms of Astragalus membranaceus var. mongholicus
By setting up indoor pot experiments of DSE-Astragalus membranaceus var. mongholicus seedlings under drought (70% and 40% filed water capacity) and heavy metal Cd (0, 5, 10 and 15 mg Cd/kg) single and combined stress, high-throughput sequencing analysis and non-targeted metabolomics technology were used.
