A potted-spinach experiment was conducted to investigate the effects of four kinds of copper products,namely,Kocide2000(KCD),Bordeaux nutrition protective powder(BNPP),Bordeaux mixture(BDM),copper sulfate(CS) and organic matter on the soil quality.Results showed that soil catalase activity was stimulated by the copper products and the inhibition of urease and sucrase activities by copper products were also observed,especially declined significantly in the treatment of BDM,the two enzymes activities in high BDM treatment were not detected.Moreover,the biological indexes of soil were affected,basal respiration and metabolic quotients were increased,microbial carbon was declined.Correlation analyses indicated that there existed significant negative correlation and positive correlation between biological and enzyme activity and available Cu.Furthermore,the available Cu and Zn(besides BDM) were increased,whereas available contents of Fe,Mn were obviously lower than contrast;pH (besides CS) was increased,EC(besides BDM) was declined.The order of the four copper products based on their effects on soil biochemical characteristics was: BDM>CS>BNPP>KCD.The application of organic matter weakened the effects of copper products on biology and enzyme activities,but the available contents of heavy metal were improved.
