This study examined the use of an artificial soil substrate in a mine waste reclamation area and its effect on plant metabolic functions. Research was conducted by determining the relationship between the plants' biochemical features and the properties of plant growth medium derived from post-flotation coal waste, sewage sludge, crushed stone and fly ash on the surface of the mine waste disposal area. Trees and shrubs were established on the material and allowed to grow for eight years. The study determined that the applied plants and the naturally occurring were suitable for physio-biochemical assessment, identification of derelict areas and reclamation purposes. An evaluation of a soil substrate applied to post-mining areas indicated that it was beneficial for plant growth since it activated the metabolic functions of herbaceous plants, shrubs, and trees. The study showed that soil substrate can be targeted to improve plant stress tolerance to potentially toxic elements (PTEs). These data suggest the potential for growth and slower susceptible response to Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn. It is possible that the constructed soil-substitute substrate (biosolid material) would be an effective reclamation treatment in areas where natural soil materials are polluted by PTEs. This observation may reflect a more efficient use of soil substrate released from the cycling of organic biogene pools, in accordance with the circular economy approach. In further studies related to land reclamation using sewage sludge amendments, it would be necessary to extend the research to other stress factors, such as salinity or water deficiency.
本研究考察了人工土壤基质在矿山废弃地复垦区的应用及其对植物代谢功能的影响。研究通过测定植物生化特征与浮选后煤矸石、污水污泥、碎石和粉煤灰在矿山废物处置区表面生长介质特性之间的关系来进行。在该材料上种植了树木和灌木，并让其生长了八年。研究确定，所应用的植物和自然发生的植物适合进行生理生化评估、废弃区域识别和复垦目的。对应用于矿山废弃地的土壤基质的评估表明，它有利于植物生长，因为它激活了草本植物、灌木和树木的代谢功能。该研究表明，土壤基质可以针对提高植物对潜在有毒元素（PTE）的胁迫耐受性进行靶向处理。这些数据表明，生长和对 Cd、Cr、Cu、Fe、Mn、Ni、Pb 和 Zn 的敏感性反应较慢是有可能的。在受 PTE 污染的天然土壤材料的地区，构建的土壤替代基质（生物固体材料）可能是一种有效的复垦处理方法。这一观察结果可能反映了根据循环经济方法，从有机生物基因库循环中释放的土壤基质的更有效利用。在与使用污水污泥改良剂进行土地复垦相关的进一步研究中，有必要将研究扩展到其他胁迫因素，如盐分或水分不足。
