连作障碍是制约蔬菜产业可持续发展的重大问题之一，一直受到国内外学者广泛关注。为了促进土壤资源的合理利用和生态环境保护，推动甘肃省高原夏菜产业的可持续发展，对甘肃省高原夏菜连作障碍的发生现状、机制及消减关键技术进行了梳理和总结，并结合目前对高原夏菜连作障碍的研究仍然存在缺少基础数据调研；缺乏机理研究，科学解析不足；关键技术与产品研发滞后；区域化综合防控模式体系空白等方面的不足，提出了全面调查高原夏菜连作障碍发生现状和程度、强化高原夏菜连作障碍发生和形成机理研究、突破高原夏菜连作障碍消减关键技术及产品研发、构建高原夏菜连作障碍综合防控模式与体系等研究重点，以期为该领域的研究和实践提供科学依据。

Continuous cropping obstacles are one of the major issues restricting the sustainable development of the vegetable industry, and have been widely concerned by scholars domestically and internationally. To promote the rational utilization of soil resources and the protection of the ecological environment, and to support the sustainable development of the plateau summer vegetable industry in Gansu Province, this article summarizes the current situation, causes, and prevention and control strategies of continuous cropping obstacles in high-altitude summer vegetables in Gansu Province. It points out that there are still four shortcomings in the current research on continuous cropping obstacles in high-altitude summer vegetables, including lack of basic data survey; lack of mechnism research and insufficitent scientific analysis; key technology and product lag behind; and the lack of a comprehensive regional prevention and control mode system. Future research should focus on: conducting comprehensive surveys on the occurrence status and extent of the obstacle; strengthening studies on the occurrence and formation mechanisms; breaking through technical bottlenecks and developing mitigation products; and constructing integrated prevention and control models and systems. These efforts aim to provide scientific support for further research and practical application in the field.
