The study of root exudates enriches the theories and methods of rhizospheric soil ecology, and offers theory warranty that it can be used in agriculture and forest. This paper discusses the types and components of root exudates, mechanism of exudation, and the relationship between root exudates and the biotic and environmental factors. The development tendency and study aspect of root exudates in the future was evaluated as well.
