Effect of the Different Dosages of Silicon on Growth of Wheat Seedling under Hydroponic Culture

[Objective]The effect of silicon treatment on the physiological growth of wheat seedling was studied.[Method] The effect of silicon treatment on the growth of wheat seedling under hydroponics culture was studied with wheat seedling being taken as experimental material,and the treatments were added with the silicon liquid prepared with Hougeleisi solution with the final concentration of silicon: 60,120-180 mg/L and the CK was added with Hougeleisi solution.[Results] The concentration of silicon of 120-180 mg/L could improve the biomass of wheat seedling;the treatment of the concentration of silicon of 60-180 mg/L could reduce the ratio of stem to root,the content of chlorophyll and soluble protein in leaf of wheat seedling;but raise the content of soluble saccharose in the leaf of wheat seedling and improve the biomass of wheat seedling,respectively.[Conclusion] Under the experimental condition,the silicon-adding could inhibit the growth of wheat seedling.
