Abstract: Effects of four kinds of modifiers on growth and chlorophyll content of Eulaliopsis binata growing on the soil polluted by lead/zinc gangue were investigated.The results show that the plants in the treated soils grew much better than in CK,with biomass of the shoots increased by over 100%（P≤0.05）.All the four kinds of modifiers lightened the poisoning effect of the heavy metals on Eulaliopsis binata,but varied in effect in the order of calcium magnesium phosphate>（CaCO₃>）organic manure>sea-foam.With the rise of the application rate of CaCO₃,biomass and chlorophyll content of Eulaliopsis binata presented a downward trend;while with the rise of the application rate of the other three,biomass of Eulaliopsis binata showed an ascendant trend,but chlorophyll content a trend of rise first,then fall.
