评估植物提取物对土壤性质的影响对于成功实施这一方法是很重要的。研究了景天提取液对镉、锌、铅污染土壤中金属有效性和微生物群落(生物量和结构)的改善作用。植物提取显著降低了根际土壤中Cd、Zn的酸可提取态、Mn/Fe氧化物和有机质结合态，以及酸可提取态的Pb值。土壤微生物生物量、总生物量、细菌、放线菌、真菌、AM真菌和原生动物磷脂脂肪酸(PLFAs)显著增加。真菌与细菌、革兰氏阳性菌与革兰氏阴性菌PLFAs的比例均发生了明显变化。冗余度分析表明，微生物生物量和PLFAs特定类群与有效金属呈负相关，与溶解有机碳/有机酸呈正相关。综上所述，植物提取物是一种较好的植物提取方法。Alfredii降低了有效金属浓度，改善了土壤微生物特性。
Assessing the effects of phytoextraction on soil properties is important for successful implementation of this method. This study was conducted to evaluate the effects of phytoextraction bySedum alfrediiHance on the availability of metals and improvement of the microbial community (biomass and structure) of a Cd, Zn and Pb contaminated soil. Phytoextraction significantly decreased the acid extractable, Mn/Fe oxide and organic matter bound fractions of Cd and Zn as well as the acid extractable Pb in the rhizosphere soil. Soil microbial biomass, total, bacterial, actinomycete, fungal, AM fungal, and protozoa phospholipid fatty acids (PLFAs) were significantly enhanced. The ratio of fungal to bacterial and gram-positive to gram-negative bacterial PLFAs were significantly changed. Redundancy analysis showed that microbial biomass and specific groups of PLFAs were negatively correlated with available metals while positively correlated with dissolved organic carbon/organic acids. In conclusion, phytoextraction byS. alfrediireduced available metal concentrations and improved soil microbial properties.
