Abstract:This study mainly discussed the biological control technology of vegetable continuous cropping obstacle. Firstly, the definition, causes and effects of continuous cropping obstacles on agricultural production of vegetables were summarized. Then, the concept, classification, principle and mechanism of biological control technology were introduced in detail, and the advantages and disadvantages of common biological control technology of vegetable continuous cropping obstacles were analyzed. Then, the application challenges of biocontrol technology in vegetable continuous cropping obstacles were discussed, including technology selection and application, environmental factors, control costs and sustainability issues. Finally, strategies to address these challenges are proposed, including the selection of appropriate biocontrol technologies, optimization of environmental conditions, and enhanced monitoring and evaluation.
Key words：Vegetable continuous cropping obstacles, biological control techniques, application challenges
