The effects of sewage sludge compost on the growth of Jasminum nudiflorum and A morpha fruti-cosa,two widely-used plants in soil and water conservation,were studied with the pot experiments.The results showed that the plant height,crown width and biomass increased gradually with sludge compost application ratio within the range of 0~5% for Jasminum nudiflorum or 0~10% for A morpha fruticosa.The application of appropriate percent age of sewage sludge compost was helpful for the growth of plants.According to toxic response factor of different forms of heavy metals,rational application rate of sewage sludge compost in Tongzhou District was determined as 3.62t/(hm ²a).
