The influences of several doses of Tebei calcium oyster powder on rice output, heavy metal concentration and basic soil fertility characteristics were studied by field plot experiment. Outcomes indicated that the use of several doses of Tebei calcium oyster powder could raise the dry matter output of rice by 5.24%∼20.65%, reduce the Cd and Pb concentration of rice by 7.80%∼53.67% and 12.63%∼60.10%, raise the pH value of soil by 4.1%∼24.5%, decrease the exchangeable acid (potential acid) by 1.0%∼53.8%, and decrease the concentration of Influenceive Cd and Pb by 64.22%∼77.98% and 4.65%∼22.59%, respectively.
