Phytomanagement has been considered a feasible technique to decrease the environmental risks associated to mine tailings and its implementation relies on a suitable plant species selection. The goal of this study was to identify the edaphic factors, including microbiology, affecting the establishment of plant species with contrasting growth patterns during the phytomanagement of mine tailings. For this purpose, a comprehensive rhizosphere characterization was performed in an early ruderal colonizer, Zygophyllum fabago and two late successional tree species, Pinus halepensis and Tetraclinis articulata, growing at a mine tailings pile in southeast Spain. The neutral pH of the tailings determined low 0.01 M CaCl₂ metal extractable concentrations (e.g. <10 μg kg⁻¹ Pb and Cd). Thus, other soil properties different from metal concentrations resulted more determining to explain plant establishment. Results revealed that Z. fabago selectively colonized tailings patches characterized by high salinity (3.5 dS m⁻¹) and high silt percentages (42%), showing a specific halotolerant rhizospheric microbial composition, such as the bacterial Sphingomonadales and Cytophagales orders and the fungal Pleosporales and Hyprocreales orders. The two tree species grew at moderate salinity areas of the tailings pile (1.7 dS m⁻¹) with high sand percentages (85%), where Actinomycetales was the most abundant bacterial order (>10% abundance). The contrasting mycorrhizal behaviour of both tree species (ectomycorrhizal for P. halepensis and endomycorrhizal for T. articulata) could explain the differences found between their fungal rhizospheric composition. In terms of phytomanagement, the selective plant species colonization following specific soil patches at mine tailings would increase their biodiversity and resilience against environmental stressors.

植物管理已被认为是减少与矿山尾矿有关的环境风险的可行技术，其实施依赖于适当的植物物种选择。这项研究的目的是确定影响采矿尾矿植物生长过程中具有相反生长模式的影响微生物等植物因素。为了这个目的，在西班牙东南部的一个矿山尾矿堆上生长的一个早期的eral鱼定居者法轮虫（Zygophyllum fabago）和两个后继的树种（Pinus halepensis和Tetraclinis articulata）进行了全面的根际鉴定。尾矿的中性pH确定为低0.01 M CaCl ₂金属可萃取物的浓度（例如<10μgkg ^-1 Pb和Cd）。因此，不同于金属浓度的其他土壤特性导致更确定地解释植物的建立。结果表明，Z. fabago选择性定植尾矿贴剂，其特征在于高盐度（3.5德尚中号^-1）和高百分比的淤泥（42％），表示特定的耐盐根际微生物组合物，如细菌Sphingomonadales和Cytophagales订单和真菌Pleosporales和Hyprocreales订单。这两种树种生长在尾矿堆的中度盐分区（1.7 dS m ^-1）的沙含量高（85％），其中放线菌是细菌数量最多的细菌（丰度> 10％）。两种树种的对比菌根行为（halepensis的根除菌根和T. articulata的内生菌根）可以解释其真菌根际组成之间的差异。在植物管理方面，在矿山尾矿上特定的土壤斑块后进行的选择性植物物种定殖将增加其生物多样性和对环境胁迫的适应力。
