记者杨舒**从中国农业科学院棉花研究所获悉，24日，该所联合中国农业科学院西部农业研究中心正式发布全球首个棉花领域专属知识大语言模型——“棉芯1.0”（CottonMind1.0），标志着我国棉花产业迈入“AI+科研+生产”深度融合的新阶段。\n\n“棉芯1.0”以“网页端+小程序端”双端设计，分别瞄准科研创新与田间生产两大核心场景。网页端为科研人员提供云端智研工作台，集成AI智能检索、文献加速阅读、知识图谱可视化等功能。小程序端可以成为棉农的随身“农技专家”，提供AI问答、拍照诊断、专家在线咨询等服务，打破了传统农技服务的时空壁垒。此外，“棉芯1.0”全平台支持中文、英文等多语言服务，为国际棉花科研协作搭建了数字化桥梁。\n\n项目组负责人杨作仁介绍，“棉芯1.0”系统已整合全球41680篇中外文科研文献、2000余项专利与国家标准、559部专业著作、1806条审定品种信息，覆盖基因功能、性状调控、品种选育、栽培管理、病虫害防控等全维度专业知识。\n\n“棉芯1.0”的发布，是我国智慧农业建设在经济作物领域的重要突破。它打通了科研成果转化“最后一公里”，构建起“科研创新—技术推广—生产应用—数据反哺”的闭环生态。同时，“棉芯1.0”通过全产业数据归集与大数据分析，可为政府部门制定种植规划、防控策略与产业扶持政策提供科学数据支撑。\n\n《光明日报》（2026年08月26日

Water Management)上。","近日，中国农业科学院西部农业研究中心联合棉花研究所揭示了干旱区滴灌棉田温室气体排放变化规律，建立了三节点滴灌棉田温室气体精准采集技术体系。相关研究成果发表在《农业水管理（Agricultural Water Management）》上。\n\n膜下滴灌水肥一体化技术为新疆棉花高产稳产提供了重要技术支撑，但灌溉施肥过程会引起土壤温室气体排放快速波动，传统采样方式难以实现农田温室气体的精准监测。\n\n该研究发现，灌溉施肥后第1天是温室气体排放峰值形成的关键时期，据此提出了“灌溉前1天—灌溉后1天—灌溉后5天”三节点精准采样方案。该方案能够在减少采样工作量的同时，保留温室气体排放关键动态信息，保持较高的排放估算精度。研究构建的关键时期识别—精准采样优化—排放精准估算技术体系，为干旱区滴灌棉田温室气体监测提供了科学方案。","中国农业科学院
