Core Viewpoint - The article highlights the advancements in grain logistics and storage in the Guangdong-Hong Kong-Macao Greater Bay Area, particularly in Dongguan, showcasing the integration of technology in enhancing efficiency and management in grain supply chains [1][9]. Group 1: Grain Logistics and Processing - The summer grain harvest and procurement have commenced, with a significant portion of the grain entering logistics and processing stages [1]. - Dongguan's Shenchiwang Port features specialized grain terminals capable of unloading up to 4,000 tons per hour, facilitating efficient grain supply [3]. - The grain hub spans over 350 acres, equivalent to 33 standard football fields, and utilizes modern technology for remote monitoring and management [4]. Group 2: Technological Integration - The grain hub employs a digital control center that manages over a thousand devices, optimizing grain flow and minimizing traffic congestion [6]. - Real-time monitoring and digital twin technology are utilized to enhance operational efficiency, allowing for precise management of grain storage conditions [8][11]. - Each batch of grain has a dedicated digital record, enabling quality monitoring and traceability throughout the storage process [15]. Group 3: Agricultural Support and Community Engagement - The Greater Bay Area has established 11 standardized supply farms and 4 service stations, connecting over 30,000 farming households through an "order agriculture + full-service" model [9][17]. - The region is developing a comprehensive grain industry chain service that includes order procurement, drying, processing, and storage, fostering closer ties with local farmers [17]. Group 4: Green Storage Initiatives - China has identified seven ecological zones for grain storage, promoting "green ecological storage" as a mainstream direction for modern grain management [18][20]. - The southern ecological zone faces challenges due to high temperatures and humidity, necessitating advanced monitoring and pest control technologies [22]. - Innovative biological pest control methods, such as the use of predatory mites, are being implemented to manage grain pests without introducing new ecological threats [26][28].
