Abstract
Pot experiments with three local legumes (Trifolium repens L., Vicia Cracca L., Medicago sativa L.) were conducted in five different amendment substrates to research into the revegetation in Lanping, Yunnan province. The main factors of restrict growing of vegetation are lack of nutrient, high concentration of Pb 2+ and Zn2+ , poor in water-holding capacity in lead-zinc tailings. Trifolium repens L. and Vicia Cracca L. are taken as pioneer plants of lead-zinc tailings according to characteristics of the three local legumes species during the growth periods about indexes of the seeding survival, height, biomass, chlorophyll content, SOD (superoxide dismutase) and CAT (catalase) activity, TF75 (75 percent tailings soil + 25 percent rural soil) amendment approach is more reasonable for the revegetation of lead-zinc tailings in Lanping based on three local legumes species growth indexes and feasibility.
