2025年比2020年提高3.1个百分点 三大粮食作物化肥利用率提升

Core Viewpoint - The Ministry of Agriculture and Rural Affairs of China reported an increase in the fertilizer utilization rate for major crops, indicating improved agricultural efficiency and sustainability [2][3]. Group 1: Fertilizer Utilization Rate - By 2025, the fertilizer utilization rate for wheat, corn, and rice is projected to reach 43.3%, an increase of 3.1 percentage points from 2020 [2]. - In 2024, the total application of agricultural fertilizers is expected to be 49.88 million tons, a reduction of 1.034 million tons (17.2%) compared to 2015, while grain production increased by 6.9% during the same period [3]. Group 2: Factors Supporting Increased Utilization - The promotion of soil testing and formula fertilization has been crucial, with over 2.3 billion acres of land covered, achieving over 95% coverage for major crops [4]. - The "Three New" integrated model, which includes new fertilization technologies, products, and equipment, has significantly contributed to the increase in fertilizer utilization rates [4]. - The use of organic fertilizers and microbial fertilizers as alternatives to chemical fertilizers has enhanced nutrient efficiency, with over 650 million acres of organic fertilizer application expected by 2025 [5]. Group 3: Specialized Services and Support - The development of specialized scientific fertilization service organizations, with over 17,000 existing nationwide, has facilitated the implementation of advanced fertilization techniques [6]. - The average reduction in fertilizer use in trial areas is around 10%, demonstrating the effectiveness of integrated nutrient management practices [6]. - The Ministry of Agriculture and Rural Affairs aims to strengthen the management of fertilizer and water resources, focusing on precision management and policy guidance to further enhance fertilizer utilization [6].
