Amelioration Effect of Apatite and Other Amendments in Cu Contaminated Soil——The Distribution of Cu Forms, Soil Enzyme Activity and Number of Microbial
磷灰石等改良剂对铜污染土壤的修复效果研究——对铜形态分布、土壤酶活性和微生物数量的影响

The effects of distribution of Cu forms,soil enzymatic activity and amount of microbial were studied in a field experiment after applied with apatite,lime,charcoal,pig manure and iron powder in Cu polluted soil.The results showed that percent of exchange state Cu decreased,percent of carbonate combined state Cu,Fe-Mn oxide combined state Cu and organic combined state Cu increased,but did not influence significantly residual state Cu.The activities of hydrogen peroxidase and acid phosphatase increased with a...
