摘要: Composting is one of the most appropriate methods to recycle sewage sludge. Sewage sludge compost a suitable solution for improving quality barren soil at landfill. Therefore, it important investigate effects on plants. Different application (mixing and scattering over reclaimed soil) sawtooth oak (Quercus acutissima) Japanese red pine (Pinus densiflora) have been tested. The markedly increased moisture nitrogen content. Compost treatments resulted in significant increases both plant height biomass as compared controls. led increase N content leaves. chlorophyll photosynthetic rates (compost 2) lower total antioxidant activity superoxide dismutase than mixing with 1), or control treatment. Since growth rates, content, 2 treatment were not different from 1 treatment, would be better method an ecological economic perspective.
