大蒜的化感作用及种植模式研究进展OA

This study takes existing literature as the research object and systematically sorts out the types,mechanisms of action,and application effects of garlic allelopathic substances in intercropping,crop rotation,and other planting modes,And clarify the core path to alleviate continuous cropping obstacles by integrating literature with practical production,Based on this,the core mechanism of garlic allelopathy was revealed(direct inhibition of pathogenic bacteria:by releasing active substances such as allicin and thioether compounds,the growth and reproduction of soil borne pathogens in the soil were directly inhibited,reducing the incidence of diseases;regulation of rhizosphere microbiota:by changing the structure of rhizosphere soil microbial communities,increasing the abundance of beneficial bacteria,inhibiting the colonization of harmful bacteria,and improving soil microenvironment stability;enhancement of soil fertility:by affecting soil enzyme activity,promoting organic matter decomposition and nutrient conversion,indirectly improving soil fertility),This article elaborates on the application value of garlic allelopathy,points out the research limitations of existing literature,and looks forward to future research,in order to provide theoretical basis and practical reference for optimizing garlic planting system,promoting green agricultural technology innovation,and helping to achieve the goal of sustainable agricultural development.
