央视农业农村频道作为国家级农业媒体，其短视频生产和传播在媒体融合时代呈现出新的特征，取得了显著的实践成效。通过对哔哩哔哩(B站)平台上的央视农业短视频进行系统分析，可以发现其在生产和传播方面已经形成一套相对稳定的平台化传播范式。从这一范式中，能够了解到央视农业频道是如何通过短视频实现专业性与接地气相融合的，是如何重构其在“三农”传播中引领角色的，进而揭示当今主流媒体在新平台生态中实现“破圈”传播的内在规律，为传统媒体平台化转型提供具有借鉴意义的经验性样本。

China Central Television Agriculture and Village Channel is China's national-level agricultural media. In the context of media convergence,its short-form video practices have produced notable outcomes and demonstrated new characteristics in content production and dissemination. This study systematically analyzes the channel's agricultural short-form videos on the Bilibili platform and reveals its relatively stable platformisation paradigm of content production and dissemination. This paradigm shows how the channel integrates professionalism with accessibility through short-form video,reshapes its leading role in agriculture,rural areas and farmers,and reveals how mainstream media gains popularity in new platform ecosystems,offering experience for the platformisation of traditional media.
