Core Viewpoint - The evolution of grain storage facilities in China reflects a significant upgrade in food security, transitioning from traditional methods to modern, intelligent, and environmentally friendly storage solutions [1][7]. Group 1: Historical Development of Grain Storage - Early grain storage facilities were simple earthen structures with limited capacity, leading to significant grain loss due to poor conditions and pest infestations [2]. - The first technological upgrade occurred in the 1950s with the introduction of the "Soviet-style warehouse," which improved storage capacity but still faced limitations in efficiency and suitability for various climates [3]. - The 1980s and 1990s saw the emergence of brick-concrete warehouses, enhancing storage quality and reducing grain loss significantly through improved sealing and ventilation [4]. Group 2: Current State of Grain Storage - Modern grain storage primarily consists of large flat warehouses and shallow round warehouses, equipped with advanced storage technologies that ensure better pest control and moisture management [5]. - The construction of new generation smart green warehouses emphasizes intelligent monitoring and environmentally friendly preservation techniques, marking a shift towards sustainable storage practices [7]. Group 3: Future Developments and Initiatives - The Chinese government plans to enhance grain storage infrastructure during the 14th Five-Year Plan, focusing on green storage technology and the establishment of demonstration points for new storage techniques [8]. - The current grain storage capacity in China has reached over 700 million tons, aligning with annual grain production levels, supported by the largest grain internet of things system globally [8].
