As shown in Table 3，spraying plant nutrient at different growing stage could significantly decrease Cd content in rice root，stalk or stem，leaf and grain（P<0.05），and the T1 got the best effect，followed by the T2 and the T3.The decrease of Cd content in brown rice was the most significant（P<0.05），which was 23.3%to 53.4%，among them，Cd content in brown rice of the T1 was only 46.6%of that of the control，followed by the T2.This showed that spraying plant nutrient at different growing stage could obviously reduce the absorption of Cd by rice root system，as well as Cd content in brown rice；and the effects of spraying plant nutrient on rice in the Cd content at the three stages which involve the tillering stage，the heading stage，the dough stage，were better than at the two stages involving the tillering stage and the heading stage which was better than at the one stage（tillering stage）.
