Core Insights - China's high-standard farmland area has exceeded 1 billion mu, with over half of the arable land capable of irrigation and drainage, ensuring that over 95% of the crops are grown from domestically bred varieties [1] - The promotion of integrated yield-increasing technologies is essential for enhancing grain production capacity, which includes good land, good seeds, good timing, and good methods [1] - The implementation of yield-increasing actions for rice has been expanded in 2023, following successful initiatives for corn and soybeans in 2022, and for wheat and rapeseed in 2024 [1] Group 1: High-Standard Farmland - High-standard farmland provides a solid foundation for increasing yields, characterized by its flatness which facilitates the operation of harvesting machinery and reduces losses [5] - The flat terrain allows for precise irrigation and drainage, essential for the varying water needs of rice at different growth stages [5][7] Group 2: Technological Innovations - The introduction of high-quality seed varieties with high seed-setting rates and disease resistance is crucial for yield improvement [9] - Innovative sowing techniques, such as "precision strip sowing," enhance seed efficiency and increase seedling rates compared to traditional methods [9] - Improved soil quality, with enhanced water and nutrient retention capabilities, is vital for successful rice cultivation [9] Group 3: Comprehensive Agricultural Services - Establishment of agricultural service centers provides full-process socialized services, ensuring efficient drying and management of harvested rice [11] - The comprehensive management from seedling to harvesting ensures that every grain is accounted for and quality is maintained [11] Group 4: Nationwide Impact - The yield-increasing actions are being implemented in 702 counties across the country, aiming to elevate the production levels of large fields to match those of experimental fields [13]

我国高标准农田面积超过了10亿亩，一半以上耕地实现旱能浇、涝能排。农作物自主选育品种面积占比超过了95%，做到了"中国粮"主要用"中国种"。 粮食综合生产能力的提升，需要集成增产技术的推广应用。所谓集成增产技术，包括良田、良种、良机和良法。"十四五"期间，我国通过在一个个粮食主产 区推广这样的集成增产技术，带动了粮油作物大面积单产提升。2023年刚开始实施时，是玉米和大豆，2024年扩大到了小麦和油菜，今年又增加了水稻。 那么，今年水稻单产提升行动有哪些新举措，提升效果如何呢？ 田琪永：今年中国农业科学院中国水稻研究所在这里，从源头出发，进行了一系列改进。 高标准农田为单产提升提供坚实的基础 田琪永：首先，要说说高标准农田。我国的高标准农田是因地制宜、因作物制宜的。这里的高标准农田，非常平整。带来的第一个好处，非常利于收割机等 农机作业，同时地面平整有利于机收减损。另外还有一点值得注意，"平整"是水稻高产的基础，这里的田面高低差要控制在极小范围内。如果不平，高处会 干旱，低处会深水淹苗，导致水稻长势不均，会严重影响产量。 平整还带来一个好处，方便这里的高标准农田能做到"快灌快排"。这是因为，水稻在不同的生长阶 ...
