Abstract

A pot experiment in greenhouse was conducted to study the effect of coal based humic acids and exogenous Cu on pakchoi. The results indicated that application of certain concentrations exogenous Cu increased the yield and nutrient contents of pak-choi. The coal-based humic acids of No.10 significantly inhibited the absorption of pak-choi to Cu and the coal-based humic acid of No.9 also had a certain inhibition. The coal-based humic acids of No.6 and No.11 promoted the absorption of pak-choi to Cu, as well as EDTA. Thus, the coal-based humic acid of No.9, in particular the coal-based humic acid of No.10 could be used to reduce the biological toxic effects of Cu in Copper contaminated soil. The coal-based humic acids of No.6 and No.11 could be applied to phytoremediation of soil contaminated with heavy metal Cu for enhancing the effectiveness and efficiency.
