【摘要】 无土栽培水培技术是代表现代农业发展方向的重要生产模式。移动式栽培槽系统（Moving Gutter System,MGS）作为一种国际先进的自动化营养液膜技术（NFT）装备，以其高密度、自动化与空间高效利用的特点，在叶菜生产中展现出巨大的潜力；然而，该系统在国内引进较晚，缺乏配套的本土化生产技术规范，制约了其应用推广。本研究以北京农业职业学院智能温室内的MGS系统为平台，针对生菜生产开展全产业链技术集成研究。通过系统性的本土化改良与实践，明确了适宜北京地区周年生产的耐性生菜品种，优化了与大孔径定植穴相匹配的潮汐式育苗技术规程，并集成了涵盖精准移栽、水肥一体化、环境精准调控及基于预防的病虫害综合防控等关键技术。实践表明，该技术可实现生菜年产10～12茬，单位面积年产量75～80 kg/m~2的目标，较露地种植增产10～12倍，同时节水90%～95%。同时，针对MGS系统设备运维成本高、专用耗材依赖进口及种植区内病虫害防控不便等技术瓶颈，提出加快关键设备与耗材的国产化替代研发、建立适配无人种植区的智慧植体系等建议。更多还原

【Abstract】 Soilless hydroponic technology represents a pivotal production mode in modern agriculture. The Moving Gutter System(MGS), an internationally advanced automated Nutrient Film Technique(NFT) equipment, demonstrates significant potential in leafy vegetable production due to its high-density, automated, and space-efficient characteristics. However, its late introduction in China and the lack of supporting localized production technical specifications have hindered its widespread application and promotion. This study utilized the MGS system within the intelligent greenhouse of Beijing Vocational College of Agriculture as a platform to conduct a comprehensive technology integration study for lettuce production across the entire industry chain. Through systematic localization improvements and practical application, suitable resilient lettuce varieties for year-round production in the Beijing area were identified. The technical protocol for ebb-and-flow sub-irrigation seedling cultivation, compatible with large-aperture planting holes, was optimized. Furthermore, key technologies were integrated, encompassing precise transplanting, integrated water and fertilizer management, precise environmental control, and a preventive-based integrated pest management strategy. Practice has shown that this integrated technology enables an annual production of 10-12 lettuce cycles, achieving a yield of 75-80 kg/m~2. This represents a 10-12 fold increase in yield compared with open-field cultivation, while simultaneously saving 90%-95% of water. At the same time, in response to technical challenges such as the high operational costs of MGS system equipment, reliance on imported specialized consumables, and inconvenient pest and disease control in planting areas, suggestions have been proposed to accelerate the research and development of domestic alternatives for key equipment and consumables, and establish a smart plant protection system adapted to unmanned planting areas.更多还原
