A field experiment was conducted to test the influences of several doses of Yuetian brand soil conditioner on dry matter output and heavy metal concentration of rice, and the influence of basic physical and chemical properties of soil. The outcomes indicated that the dry matter output of rice was increased by 1.29%∼23.42% by using different dosage of Yuetian brand soil conditioner compared with no soil conditioner treatment (treatment 1). The effect of Treatment 5 (1875kg/ha) was better on enhancing dry matter output of rice. And they could reduce Cd and Pb concentration of rice by 17.32%∼60.17% and 11.47%∼64.68%, respectively. Ttreatment 5 and 6 had a better effect on reducing heavy metal concentration in rice, and could increase the pH of the soil by 4.7%∼37.2% and decrease the exchangeable acid (latent acid) by 3.5%∼55.9% , the concentrations of soil effective Cd and Pb were reduced by 9.28%∼49.48% and 8.34%∼24.40% , respectively.
