视频丨1.43万亿斤！为何今年全国粮食产量再创新高？

Core Viewpoint - The national grain production has reached a new high despite facing severe natural disasters, highlighting the resilience and improvements in agricultural practices in key production areas like the Huang-Huai-Hai region [1][5]. Group 1: Regional Focus - The Huang-Huai-Hai region, which includes provinces such as Hebei, Shandong, Henan, Jiangsu, Anhui, Shanxi, and Shaanxi, has been significantly impacted by natural disasters in recent years, affecting grain production [1]. - Despite these challenges, the region has strengthened its agricultural infrastructure, including the dredging of over 100,000 kilometers of ditches and the establishment of emergency service centers to enhance disaster response capabilities [3]. Group 2: National Grain Production Trends - Over the past five years, grain production across the country has been on the rise, with significant contributions from corn, which is the largest grain crop in China, accounting for 42.1% of total grain production in 2025 [7][9]. - The increase in grain production is attributed to both the expansion of planting area and improvements in yield per unit area, with corn area increasing by 3.3 million acres [9]. Group 3: Yield Improvement Factors - The rise in corn yield is driven by the adoption of high-yield varieties that are resistant to pests, drought, and other adverse conditions, ensuring stable growth under varying circumstances [10]. - Innovative planting techniques, such as "reasonable close planting," have been implemented, increasing planting density significantly, which is a core part of the national corn yield enhancement initiative [12].
