Data from a pot scale experiment with mine tailing material and Agrostis capillaris L. alone, or mixed with Melilotus albus Medik

The data set consists in a file with four sheets: one includes a legend (treatment number, treatment code, description, and code for the other measurements at time zero (t=0); the second sheet contain data lab at time zero which is a matrix with 67 rows and 38 columns. In this matrix there are variables measured for the characterization of a mine tailing (MT) substrate sampled from three points on the Valea Șesei pond with 5 replicates each, top soil (TS) used as amendment and sampled from a single point in five replicates near the pond, and green fertilizers used (Tr - a mixture of Trifolium pratense L. and Trifolium repens L., and Ms - Medicago sativa) in one composite sample for each species from which five replicates were used. In addition, a screening of the elements uptakes from the MT was done in two pioneer species found on the pond, 9 individuals of Tussilago farfara L. roots (RT) and shoots (ST) and 6 individuals of Equisetum arvense L. roots (RE) and shoots (SE). A second screening was done for the elements in the water (the first 4 samples were from sampling points downstream of the pond, and the last 3 were sampled from the tailing pond, from the accessible areas. In the third sheet with 282 rows and 45 columns are presented results of the variables measured in the technosoil and in the vegetation obtained from 14 experimental treatments using TS; Tr, Ms F1% or F2% (Rhizophagus irregularis L.) and plants. The vegetation consisted of Agrostis capillaris L. roots and shoots in single culture, and Agrostis capillaris L. grown together with Melilotus albus Medick., both with roots and shoots. In the fourth spreadsheet there is a table with calculations for mycorrhizal colonization presented in 47 rows and 57 columns. The experimental design is detailed on the second page of the Excel file with the raw data. Keywords: arbuscular mycorrhizal fungi, heavy metals, phytoremediation, technosoil本数据集包含一个包含四个工作表的Excel文件。第一个工作表为说明表，涵盖处理编号、处理代码、描述信息，以及零时刻（t=0）其余测量项的代码；第二个工作表为零时刻实验室检测数据集，为67行38列的矩阵，其中包含用于表征矿山尾矿（mine tailing，简称MT）基质的各项测量变量：该基质采自Valea Șesei池塘的3个采样点位，每个点位设置5个重复样本；同时包含用作改良剂的表层土壤（top soil，简称TS），该土壤采自池塘附近1个点位，设置5个重复样本；以及所用的两种绿色肥料：Tr为红三叶（Trifolium pratense L.）与白三叶（Trifolium repens L.）的混合物，Ms为紫花苜蓿（Medicago sativa），每种肥料取1份混合样品后设置5个重复样本。此外，本研究针对该池塘中发现的两种先锋物种对矿山尾矿基质中元素的吸收情况开展了筛选试验：采集了9株款冬（Tussilago farfara L.）的根（RT）与地上部分（ST），以及6株问荆（Equisetum arvense L.）的根（RE）与地上部分（SE）。第二次筛选针对水体中的元素含量进行：前4个采样点位位于池塘下游区域，后3个采样点位取自尾矿池塘的可及区域。第三个工作表为282行45列的矩阵，展示了14组实验处理下的技术土壤（technosoil）及植被的各项测量结果，实验处理因子包括表层土壤（TS）、Tr、Ms、F1%或F2%的不规则根囊霉（Rhizophagus irregularis L.）以及供试植物。供试植被包括单栽的匍匐翦股颖（Agrostis capillaris L.）的根与地上部分，以及匍匐翦股颖与白香草木犀（Melilotus albus Medick.）混栽组合的根与地上部分。第四个工作表为47行57列的菌根定殖率计算表。本数据集的实验设计细节详见原始数据Excel文件的第二页。 关键词：丛枝菌根真菌，重金属，植物修复，技术土壤
