Abstract:

Plants and soil microorganisms are closely related, and both play a central role in the carbon cycle mediated by soil microorganisms, they jointly maintain the global carbon balance and the function of ecosystems. Firstly, an overview of the carbon cycle mediated by soil microorganisms was provided. Secondly, the impact of plants on the carbon cycle mediated by soil microorganisms was analyzed, which was specifically reflected in plant photosynthesis, plant respiration, decomposition of plant litter, secretion of plant aboveground secretions, and the rhizosphere effect produced by plants. Among them, the impact of the rhizosphere effect produced by plants on the carbon cycle mediated by soil microorganisms was also reflected in the secretion of plant root exudates and the symbiosis between plants and soil microorganisms. Finally, the impact pathways of plants on the carbon cycle mediated by soil microorganisms were summarized. By reviewing the impact of plants on the carbon cycle mediated by soil microorganisms, it could deepen the understanding of soil carbon cycling and provide a scientific foundation for future environmental protection.

Key words: soil microorganisms, carbon cycle, plants, soil carbon cycling, rhizosphere effect
