Abstract: A pot experiment was conducted to test the effects of bamboo charcoal on rice growth， soil chemical properties， soil heavy metal availability in the polluted soil by heavy metals. Treatments of bamboo charcoal were combinations of four rates (0， 5， 10 and 20 g·kg-1) and two particles sizes (2 and 025 mm mesh sieves). The results showed that total dry weight of rice plants increased with increasing rates of bamboo charcoal; addition of bamboo charcoal significantly increased soil pH and organic matter contents. Compared to the control， soil heavy metal availabilities were significantly increased by bamboo charcoal， especially for Cu and Zn. For the treatment of 025 mm bamboo charcoal with 10 g·kg-1， the content of Cd in rice grains was significantly decreased.
