- Abstract:
-
Litter is the main way for plants to import organic carbon into the soil. Part of the carbon from the litter is lost into the atmosphere in the form of CO2, and the other part is input into the soil in the form of organic carbon. Under the action of soil microorganisms, the litter-derived carbon undergoes a series of processes to participate in the formation of stable organic matter. However, the soil is a black box, and the process and mechanism of the transfer of litter to soil organic carbon are still unclear. This article combines the main results of this research field at home and abroad, and briefly introduces the research methods of plant litter decomposition, soil organic carbon components and soil organic carbon stability, and summarizes the effects of plant litter decomposition on soil organic carbon and its components, soil respiration, priming effects, and soil microbial community structure and enzyme activity and the effect of plant-soil-microorganism interaction process on the stability of organic carbon. The relationship between plant litter decomposition and the formation of stable soil organic carbon is clarified. The future urgently needed research directions and research content in this field are pointed out.
