Core Viewpoint - The article emphasizes the importance of both increasing grain production and reducing losses in the context of food security, highlighting Shandong's efforts in optimizing the entire grain supply chain to achieve these goals [1] Group 1: Grain Production and Yield Improvement - Shandong has maintained a stable grain production of over 110 billion jin for four consecutive years, with a focus on enhancing yield through advanced agricultural practices and technology [1] - In 2025, Shandong's summer grain yield is projected to rank first in the country, achieving increases in area, yield, and total production for three consecutive years [2] - The introduction of high-yield, low-loss crop varieties and precision sowing techniques has led to a reduction in pest damage to below 5%, saving an average of 2.5 kg of seeds per mu and boosting yields by over 8% [2] Group 2: Mechanization and Harvest Loss Reduction - The average harvesting loss rate for wheat in Shandong has decreased to 0.78% in 2025, with a corresponding reduction in corn harvesting loss to 1.57% [3] - Each 0.1 percentage point reduction in harvesting loss can theoretically recover over 50 million jin of grain, equivalent to adding more than 50,000 mu of arable land [3] Group 3: Grain Storage Innovations - Advanced storage techniques, such as a central cooling system in grain warehouses, have significantly reduced grain loss by inhibiting pest growth and delaying spoilage [4] - The use of multi-parameter grain condition detection technology and intelligent ventilation systems has decreased grain loss from 8‰ to 3‰, saving 750 tons of grain during storage [5] Group 4: Support for Farmers - Shandong has invested 371 million yuan in scientific storage facilities for farmers, reducing storage loss rates by an average of 5 percentage points, equating to a reduction of 49,000 tons of grain loss annually [6] - The establishment of 280 post-harvest service centers has further decreased post-harvest loss rates by 4 percentage points, with 4.9 million tons of grain processed in 2024 [6] Group 5: Value-Added Processing - Companies in Shandong are maximizing grain utilization by producing over 600 high-value products from wheat, achieving a 100% utilization rate and saving 500,000 tons of grain annually [7] - The promotion of moderate processing techniques aims to enhance grain yield rates while meeting health standards, with pilot enterprises leading the way in reducing processing losses [8][9]

Core Viewpoint - The integration of agricultural enterprises and research institutions in Shandong has accelerated the promotion of high-yield wheat varieties, particularly the new variety "Luyuan 951," which shows significant potential for large-scale planting and high productivity [2][3]. Group 1: Wheat Variety Promotion - The "Luyuan 951" variety has been planted on 360 acres by a local cooperative, with expected yields reaching 800 kilograms per acre, showcasing its strong tillering ability and high resistance to lodging and diseases [2]. - The rapid increase in planting area from 30,000 acres in 2023 to 1.5 million acres in 2024 highlights the effectiveness of the collaboration between Shandong Academy of Agricultural Sciences and Luyuan Company [2][3]. Group 2: Research and Development Integration - The deep integration of research and enterprise allows for immediate feedback from farmers, enabling breeding goals to align closely with market demands, thus accelerating the transition from research to application [3]. - The seamless connection between variety approval and promotion can lead to a 2-3 year advancement in large-scale adoption compared to traditional methods [3]. Group 3: High-Quality Wheat Varieties - The "Jimai 44" variety, developed through similar integration efforts, has been recognized as one of the top domestic wheat varieties, outperforming U.S. hard red winter wheat and achieving a record yield of 808.6 kilograms per acre in 2022 [4]. - The demonstration area at the event showcased over 30 new wheat varieties, including "Luyuan 951" and "Jimai 44," indicating a strong focus on high-yield and disease-resistant wheat development [4].
