| description | Bioaugmentation is an important measure for improving the efficiency of phytoremediation. The objective was to identify the role of exogenous plant debris with different processing and microbial agents for soil characteristics, copper bioavailability and phytoextraction. The experimental design consisted of four blocks, which were divided into 48 plots. Each plot was planted with <i>Fraxinus chinensis</i> and <i>Salix matsudana</i> × <i>alba</i>, which was added to plant composts, woody chips and effective microorganisms (EM) agents, using an orthogonal experimental design. The results showed that the order of bioaugmentation materials on the Cu phytoextraction of two woody species was plant composts > wood chips > EM agents. The best performance of <i>F. chinensis</i> was in the T15 treatment (30% plant composts + 7.5% wood chips + 40 mL·m<sup>−2</sup>), with phytoextraction of 33.66 mg·m<sup>−2</sup>, as well as 4.32 mg·m<sup>−2</sup> in the T16 treatment (30% plant composts + 15% wood chips) of <i>S. matsudana</i> × <i>alba</i>. Cu was accumulated mainly in the roots of the two woody plants. The phytoextraction of the above-ground parts was promoted by bioaugmentation, due to the improvement in the physical soil characteristics and Cu bioavailability. The phytoextraction performance of <i>F. chinensis</i> was promoted by the improvement in the Cu concentration after treatments, while for <i>S. matsudana</i> × <i>alba</i>, it was the dry biomass. Thus, targeted strengthening measures should be to applied, to improve the efficiency of phytoremediation. |
