In the present study, sheep manure (0%, 10% and 20% w/w) and biochar derived from coniferous tree woods (0%, 2.5% and 5% w/w) were incorporated into a multi-MTE contaminated soil from a former iron mine site and incubated for 10 days. A seeds of barley were grown in the amended soil and different morphological traits were measured after 30 days. Results indicated that MTE stress reduced the shoot length, stem diameter, leaf area, number of leaves and dry biomass as compared to the control. Organic amendments application increased soil pH and was found to affect significantly almost all the measured parameters. Animal manure was found effective in improvement of the morphological characteristics of barley plants comparing to biochar amendments. Our results suggested that animal manure could be used for reducing the effect of MTE on the morphological proprieties of barley grown in a former iron mine soil.

在用生物炭和动物粪便改良的受污染的矿化土壤中,大麦的生长,存活和生物量生产。

在本研究中,绵羊粪便(0%,10%和20%w / w)和源自针叶树木材的生物炭(0%,2.5%和5%w / w)被掺入到多MTE污染的土壤中一个以前的铁矿场,并孵育了10天。大麦种子在改良土壤中生长,并在30天后测量了不同的形态性状。结果表明,与对照相比,MTE胁迫减少了芽长,茎直径,叶面积,叶数和干燥生物量。有机改良剂的应用增加了土壤的pH值,并且发现它几乎可以影响几乎所有测量参数。与生物炭改良剂相比,发现动物粪便可以有效改善大麦植物的形态特征。
