【摘要】：文章利用铁尾矿、pH调节剂及堆肥(污泥)、保水剂等构建人工土壤,通过优化调整水泥和pH调节剂含量进行试验考察植物的生长情况。以沙打旺、高羊茅、多花木兰和紫穗槐作为试验植物,分析植物的成活数、株高、地上部干重、地下部干重4个指标。就单一作物而言,沙打旺的适宜人工土壤配比为D6M12,高羊茅的适宜人工土壤配比为D6M12,多花木兰的适宜人工土壤配比为D6M18,紫穗槐的适宜人工土壤配比为D6M12,而4种作物混种情况下适宜的人工土壤配比为D6M12。
[Abstract]:The paper uses iron tailings, pH regulator and composting (sludge) and water retaining agent to construct artificial soil. The growth of plants is investigated by optimizing the content of cement and pH regulator. The survival number, plant height, dry weight of the ground and dry weight in the underground are analyzed by the experiment plant of Astragalus astragalus, tall fescue, Magnolia and Sophora japonica. As far as single crop is concerned, the suitable artificial soil ratio is D6M12, the suitable artificial soil ratio of tall fescue is D6M12, the suitable artificial soil ratio is D6M18, the suitable artificial soil ratio is D6M12, and the suitable artificial soil ratio is D6M12. under the condition of 4 kinds of crop mixed with D6M12..
