In order to guide the rational use of silicon fertilizers in agriculture，by means of literature review，this paper summarized the regulation effects of silicon fertilizer on the growth characteristics of crops，the effect of increasing yield and improving fruit quality under normal environmental conditions. In addition，the regulation effect of silicon fertilizer was summarized from the response of soil environment. Based on the existing research results，adding silicon fertilizer could boost crops′ growth and improve the crops′ yield，fruit quality，and soil environment. Meanwhile，there were different regulating effects for different silicon fertilizers，and the effect of single application of silicon fertilizers is not as good as the combination with other fertilizers or agronomic measures. Future study can focus on further deepening the regulation mechanism of improving silicon fertilizers′quality and efficiency，and accelerating the development of the cost-effective silicon，providing techical support for agriculture development with high-quality.
