酚酸类物质导致植物连作障碍的研究进展

Research Progress on the Continuous Cropping Obstacles of Plants Caused by Phenolic Acids

酚酸类物质是导致植物连作障碍的主要物质。酚酸类物质的自毒作用影响植物的膜系统、光合作用、酶活性、土壤微生物活性、土壤理化性质和内源激素等,对植物生长产生抑制作用。针对酚酸类物质的来源,酚酸类物质对土壤养分、土壤酶活性、土壤微生物和植物生理生化指标的影响的研究状况,以及如何减轻酚酸类物质连作障碍方法的研究进展进行了综述。

Phenolic acids were the main substances leading to the continuous cropping obstacles in plants.The self-allelopathy inhibited plant growth through affecting plant membrane system,photosynthesis,enzyme activity,soil microbial activity,soil physical and chemical properties,endogenous hormones and so on.This paper focused on the research progress on the sources of phenolic acids,the self-allelopathy of phenolic acids for soil nutrient,soil enzyme activity,soil microorganisms and plant physiology and biochemistry,and the research progress on how to relieve the continuous cropping obstacles caused by phenolic acids were reviewed.
