Abstract Pot and plot experiments were conducted to observe the growth of Paspalum notatum,Cynodon dactylon,Eragrostis curvula and Pennisetum alopecuroides on the rare earth tailings under the common condition,the condition without fertilizer and that with drought stress.The suitability of the four herbaceous plants on rare earth tailings were compared from the aspects of growth ability,drought tolerance and barren tolerance.The results showed that Eragrostis curvula,Paspalum notatum and Pennisetum alopecuroides were the best in terms of growth ability,drought tolerance and barren tolerance respectively.Summing up the comparisons in the three aspects,Paspalum notatum was the best,followed orderly by Pennisetum alopecuroides,Eragrostis curvula and Cynodon dactylon.The results provided reference for application of the four plants to revegetation on rare earth tailings in South China according to concrete conditions.
