间作下根际微生物控制土传病害的研究进展

为了解根际微生物在间作模式下有效控制土传病害的作用和机理，综述了间作系统对于根际微生物群落结构和代谢功能的影响，介绍了间作作物组合、作物品种选择和间作方式对根际微生物群落的影响，并从养分和宿主感染位点竞争、生防微生物的拮抗作用、植物化感自毒作用的缓解以及植物诱导系统抗性四个方面总结了与根际微生物相关的间作抗病机理。最后，讨论了现阶段间作抗病研究的局限性并对今后的研究方向进行了展望。

Progress in Control of Soil-Borne Diseases by Rhizosphere Microorganisms Under Intercropping

To understand effects and mechanisms of rhizosphere microorganism controlling soilborne diseases under intercropping system， the effects of intercropping on rhizosphere microbial community structure and metabolic functions were reviewed， and the effects of intercropping management methods， including plant combination， crop variety， and intercropping method， were also introduced. Then， the intercropping mechanisms of rhizosphere microorganisms were summarized into four main aspects: the competition of nutrient and host infection site， the antagonism of biocontrol microorganisms， mitigation of plant allelopathic autotoxicity， and stimulation of induced systemic resistance. Finally， the limitations of the research on disease control by intercropping were discussed and the future development directions were prospected.
