摘要: Abstract We used two common species of tree, Ailanthus altissima S. and Ulmus pumila L., as the model plants to study behavior abandoned reverse osmosis (RO) membrane on phytoremediation saline soil following a pot experiment up 3 years. Plants (control) or with roots wrapped by RO were cultivated in pots filled soil, irrigated twice week tap water. Data from dry weight, tissue levels mineral nutrients, chlorophyll (Chl), leaf protein content potential toxic element (Na + ) showed that significantly influenced growth development plants. A dramatic improvement leaf, branch trunk biomass A. U. L. was observed this study. Subsequently, enhanced uptake N, P K , decline Na accumulation leaves, branches trunks are suspected be largely due biological filter functions RO. In addition, Chl contents ( soil. Hence, application both plant can technique, although appears more suitable for
