Abstract
Pot experiments were carried out to determine the dynamic changes of pH,Eh,silicon concentrations of soil solutions and silicon in rice plant in growth stage of rice after application of Si-fertilizer in alkaline paddy soil.The results showed that: the pH value of all treatments were decreased and approach to neutral;applying Si-fertilizer had no obvious effect on pH,but the pH value of the treatments after glucose or glucose and blast furnace slag application were higher than that of the control in each growth stages.The Eh of all the treatments decreased sharply at first,then gradually reached a valley,and increased rapidly to a peak after the water was drawn.When the water was given again,the Eh decreased to another valley and then increased slightly.At first,all the treatments were lower than that of the control.In the late,application of Si-fertilizer could increase the soil Eh.Application of glucose or glucose and blast furnace slag application could decrease soil Eh.The silicon concentrations of soil solutions in all the treatments increased and reached a peak; then dropped gradually,and at last stabilized at a constant value.The silicon concentrations of soil solutions and silicon content in the rice plant in all the treatments after Si-fertilizer application were higher than that of the control in each growth stages.The silicon concentration of soil solution in the treatment after glucose application also was higher than that of the control in vegetative growth stages,but it could not increase silicon content in the rice plant.The results also showed that the rice yield increased significantly after application of Si-fertilizer,and the rice yield did not increase after glucose application.
