Abstract:

Plant-soil feedback (PSF), as an important driving force for plant distribution, community composition, and succession, has received extensive attention in recent years. The spatial-temporal variation are important factors driving PSF; however, there is currently a lack of review on its research progress. We summarized the research progress on the spatial-temporal variation of PSF and proposed research directions that could be pursued in the future. At the temporal scale of PSF, the relationships among plant developmental stages, experimental cycles, and feedback effects were emphasized. At the spatial scale of PSF, we focused on the spatial distribution and transfer of plants, the spatial differentiation of soil microbial communities and physicochemical factors, as well as the influence of above- and below-ground systems on PSF. Based on the research progress, we proposed to focus on the long-term, multi-point dynamic feedback to improve the temporal resolution of the feedback process. The buffering time of microbial communities on domesticated and tested plants needed to be considered, and reasonable domestication and feedback periods should be set to make the results more objective. At the spatial scale, the effects of plant spatial distribution, spatial heterogeneity of soil factors, and above- and below-ground systems on feedback effects should be paid attention. Efforts should be made to achieve similarity in the physical structure of the inoculated soil, in order to obtain more realistic feedback effects.

Key words: plant-soil feedback, temporal pattern, spatial pattern, community succession
