Abstract: In order to remedy heavy metal contaminated soil,the culture experiment was conducted to study the effects of organic and inorganic compound amendments on the biomasses of cabbage,the availability of heavy metals Pb and Cd in soils and the absorption of Pb and Cd by pot experiments.The results showed that organic and inorganic compound amendments enhanced the biomasses of cabbage,the single chicken manure treatment showed the best effect.All compound amendments could significantly decrease available Pb and Cd content in soils.The compound amendments treatment of charcoal+phosphate rock powder showed the best effect on soil Pb and Cd immobilizing effects,were 80.60% and 49.21%.The second was chicken manure+phosphate rock powder treatment,the removal efficiencies for soil Pb and Cd were 76.16% and 36.78%.Comparing with control,all compound amendments could significantly decrease Pb and Cd content of cabbage.The compound amendments treatment of chicken manure+phosphate rock powder showed the best effect on Pb of cabbage,was 79.37%.The second treatment was charcoal+phosphate rock powder.The compound amendments treatment of charcoal+phosphate rock powder showed the best effect on Cd of cabbage,was 56.55%.The second treatment was chicken manure+phosphate rock powder.Therefore,the organic and inorganic amendments treatment of charcoal+phosphate rock powder or chicken manure+phosphate rock powder was to be an efficient,cost-effective and environmentally friendly measure to calcareous soil which was slightly contaminated by Pb and Cd.
