[Rhizodeposition and its role in carbon cycling in plant-soil system].
Rhizodeposition is an important interface process of the exchange between plant and soil, and plays an important role in soil carbon turnover. The rhizodeposition of carbon is also the bridge linking plant, soil" and microorganisms. This paper reviewed the researches on the rhizodeposition in carbon balance and carbon cycling, expounded the mechanisms of carbon rhizodeposition, and discussed the problems in related experiments, the differences of rhizodeposition with plant species, cultivars and growth stages, the relationships between rhizodeposition and soil respiration, and the significance of rhizodeposition in the carbon cycling in plant-soil system. Some related research tasks in the future were also proposed.
