Abstract:

At present, continuous cropping obstacle has become an important factor restricting the sustainable development of vegetable production in some areas. the reason of continuous cropping obstacle is complex and comprehensive, and its occurrence is not only related to soil infectious diseases and soil physical and chemical deterioration. It is also related to the autotoxicity caused by root exudates and stubble decomposition. Phenolic acids in plant root exudates have been identified to have autotoxic effects on plants and have important effects on rhizosphere microorganisms. In this paper, the relationship between phenolic acids and soil microorganisms was discussed from many angles, and the interaction and influence mechanism between phenolic acids and rhizosphere microorganisms were reviewed. at the same time, several problems that need to be further studied in phenolic acids and rhizosphere microecology in the future were put forward. The study on the interaction between phenolic acids and soil microorganisms will provide theoretical basis and practical guidance for the prevention and treatment of continuous cropping obstacles.
