Core Viewpoint - The successful practice of cross-regional mechanized harvesting in China is supported by a modern agricultural social service system, which includes information platforms, maintenance stations, fuel guarantees, and financial services, enabling efficient nationwide movement of dispersed agricultural machinery resources [1][3][4] Group 1: Importance of Cross-Regional Mechanized Harvesting - The summer grain harvest, particularly wheat, is crucial as it accounts for about one-fifth of the total annual grain production, with wheat making up 90% of that [1] - Cross-regional mechanized harvesting is key to ensuring timely collection of wheat, preventing losses due to adverse weather conditions [1][4] - China, as the world's largest wheat producer, utilizes over 300,000 harvesting machines during the summer harvest, showcasing the scale of agricultural mechanization [1] Group 2: Technological Advancements - The application of advanced technologies such as artificial intelligence, IoT, and big data is reshaping agricultural operations, providing new momentum for cross-regional mechanized harvesting [2] - Smart harvesting machines equipped with Beidou navigation can accurately assess crop maturity and optimize harvesting parameters, significantly reducing missed cuts [2] - Autonomous harvesting machines can process terrain data in real-time and plan optimal paths, enhancing operational efficiency [2] Group 3: Supportive Infrastructure - The establishment of digital platforms like "Farm Machinery Direct" and "Smart Agricultural Machinery" facilitates effective supply-demand matching, improving operational efficiency and reducing labor costs [3] - Logistics support along harvesting routes includes "Farm Machinery Stations" providing fuel, maintenance, and accommodation services, ensuring uninterrupted operations [3] - The innovative "order-based service + contiguous operation" model implemented by agricultural cooperatives stabilizes farmer expectations and enhances machinery utilization [3][4] Group 4: Historical Context and Modernization - Cross-regional mechanized harvesting, which began in the 1990s, exemplifies China's agricultural modernization, addressing the challenges faced by small-scale farmers [4] - The model of resource allocation for agricultural machinery has resolved the dual issues of "having machinery without land" and "having land without machinery," preventing resource wastage [4] - Currently, over 98% of wheat harvesting in China is mechanized, with cross-regional harvesting playing a significant role in this achievement [4]
