In order to investigation the use of bio-refining of silicon on cadmium and lead in spinach, in the pot experiment Qaemshahr Agriculture University in 2012 as a completely randomized design with four replications. Treatment include silicon (150mg/kg of Potassium silicon), Pb (100 mg/kg of chloride) ,Cd (100 mg/kg of chloride),silicon+Pb, silicon+Cd and control as used soil. The results showed that the use of silicon,Pb accumulation in shoot and roots decreased (34/4 ,65/2 percents) and also Cd accumulation in shoot and roots decreased (25/7 , 37/0 percents) respectively. The lowest shoot and root lengh was with Cd and Pb application, that less than in comparison with control(42/4 , 27/8 percents) respectively. At least bush fresh weight obtained with Pb and Cd separate application and silicon and Cd joint application . results this experiment can reception that silicon application caused the decrease Cd and Pb accumulation in shoot and root spinach plant.
