有益微生物缓解花生连作障碍机理研究进展

花生是我国重要的油料作物,种植过程中会遇到连作障碍问题.有益微生物可以有效缓解花生连作障碍,其机理包括有益微生物分解化感物质、改变花生根际微生物区系、增加花生抗病能力、促进花生结瘤固氮、促进花生养分吸收五个方面.阐明该机理,对花生连作障碍缓解有指导意义,对其他作物连作障碍的缓解也有参考价值.

Research Progress on the Beneficial Microbe-Mediated Alleviation of Peanut Continuous Cropping Obstacle

Peanut (Arachis hypogaea L.) is an important oil crop of China, which often encounters continuous cropping obstacle. Beneficial microbes can effectively alleviate continuous cropping obstacle and the mechanisms include: allelochemical degradation, rhizosphere microbiota alteration, disease resistance enhancement, nodulation and N₂-fixation enhancement, nutrient absorption promotion. Clarifying such underlying mechanisms provides some insights into continuous cropping obstacle alleviation of peanut plants and perhaps other leguminous crops as well.
