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]
