Effect of Lead-Zinc Mine Tailings Amended with Sewage Sludge Organic Fertilizer on Growth of Four Herbaceous Plants and Heavy Metal Accumulation
[Objective] This paper aimed to understand the effects of sewage sludge organic fertilizer application on the amendment of lead-zinc mine tailings through the measurements of growth responses of four potted plants and heavy metal accumulation in them
in order to provide a theoretical basis for the repairing and improving of tailings by rational utilization of sludge organic fertilizer.[Methods] We adopted pot experiment and used four plants named Lolium multiflorum
Trifolium repens
Melilotus suaveolens and Astragalus adsurgens
as materials.[Results] It showed that the height
root length
biomass of plants reached the maximum when 20 g/kg fertilizer was applied. The chlorophyll a+b contents in the four plants with fertilization treatment were higher than that of the control without fertilization. The more sludge organic fertilizer was applied
the lower content of MDA in Lolium multiflorum
Trifolium repens were measured. The contents of Pb
Zn
Cd inLolium multiflorum
Trifolium repens
Melilotus suaveolens reached the maximum when fertilizer was 10 g/kg
and decreased when fertilizer was 20 g/kg.[Conclusion] It indicates that with the increased application of sludge organic fertilizer
the amount of heavy metals in plants will decrease. Sludge organic fertilizer can help to alleviate the poisoning effects of heavy metals on plants.
