粤强农装！广东丝苗米全链升级丨广货行天下

Core Viewpoint - The Guangdong province is undergoing a significant transformation in its production of Si Miao rice, transitioning from traditional farming methods to smart agriculture, with a projected planting area of 7.421 million acres and a production volume exceeding 3 million tons by 2025, accounting for nearly 30% of the province's rice area and output [3][4]. Group 1: Smart Agriculture Transformation - The integration of smart agricultural technologies, such as intelligent temperature control in seedling greenhouses and the use of drones for precise pest control, is driving the high-quality development of the Si Miao rice industry in Guangdong [5][52]. - The adoption of standardized seedling greenhouses and machine transplanting has resolved traditional challenges related to natural conditions and low transplanting efficiency, laying a solid foundation for increased rice yields [8][21]. Group 2: Mechanization and Efficiency - The mechanization of rice planting and harvesting is being promoted, with the average mechanical harvesting rate expected to exceed 97% by 2025, significantly reducing production costs and improving industry efficiency [34]. - The use of drones for pesticide application has increased efficiency, allowing for the spraying of 100 acres in one hour, improving pesticide utilization rates by 30% and reducing costs from 80 yuan to 50 yuan per acre [28][29]. Group 3: Drying and Quality Preservation - The establishment of standardized drying centers has enabled immediate drying post-harvest, effectively reducing post-harvest losses and ensuring the quality of Si Miao rice, with loss rates controlled below 3% compared to 10% with traditional drying methods [38][42]. - The integration of drying and storage systems in modern agricultural practices has extended the storage period of rice from 6 months to 12 months, ensuring freshness through IoT monitoring [47].
