酚酸类物质在作物连作障碍中的化感效应及其调控研究进展

Phenolic acids have been found as important allelochemicalsin continuous cropping systems, where they can affect crop production by autotoxicity or changing the structure of soil microbial coummunity. This paper reviews the kinds and producing pathway of phenolic acids, the dynamic changes of their contents in plant and soil, their impact on soil ecosystem and plant growth and its mechanism, and the regulation of phenolic acids. On this basis, the future research directions are prospected.It can provide a reference for the integrated control oncontinuous cropping obstacles.
