Abstract: From the points of ecological benefit and long-term effect, mixed cropping can play a positive role in controlling crop disease, pest and weed, and protecting and optimizing farmland ecosystem. In this review, the ecological risks of simplified variety type and crop pattern were briefly described. Through reviewing application examples, the crop protection mechanisms of the mixed cropping were summarized into the barrier effect, allelopathy, dilution effect as well as the interaction effect between components in the mixed system, etc. The lack of scientific collocation, benefits evaluation and compensation mechanism in the application of mixed cropping were pointed out, and the application prospect of the mixed cropping was put forward.
