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

Progressin allelopathic effect and regulation of phenolic acids for continuous cropping obstacle system

酚酸类物质是单一连作体系中重要的化感物质,可通过直接的自毒作用或间接的抑制或促进作用,影响土壤微生物的生长,改变土壤微生物群落结构而影响作物的生产。本文对酚酸类化感物质的种类、产生途径、在植物体和土壤中含量的动态变化、对土壤生态系统和植株生长发育的影响及其作用机制,以及酚酸类化感物质的调控等方面的研究进展进行综述,在此基础上展望了以后的研究方向,可为连作障碍综合调控提供依据。

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.
