Abstract: Silicon fertilizer was first research and extensively used in Japan.Following Japan,S. Korea,Thailand,Philippine,Taiwan region,most Europe agricultural developed countries and U.S.A.,etc.also carried out plenty of researches for silicon and use silicon by a large scale.silicon fertilizer have brought high benefit for their agriculture,the silicon research and application in our country start late comparatively,and concentration in the south areas of Changjiang with northeast and the North China region is blank basically.Silicon fertilizer efficiency test on maize had been down in Baotou city soil fertilizer work station,the fertilizer efficiency of silicon verified,result indicate that application of Silicon fertilizer35～50kg as base fertilizer can increase yield 6.7%～ 19.1% and top application 40kg per mu can increase yield 17.4%～21.4%.Thus result offer scientific basis for silicon fertilizer application on the maize.

Key words: Maize, Silicon fertilizer, Fertilizer efficiency
