2024年，示范区种植期雨量充沛，玉米出苗率保持在95%以上，产量达12510.7公斤\u002F公顷；2025年，示范区玉米产量为13124.6公斤\u002F公顷；2026年，面对春旱和低温冷害双重胁迫，玉米产量进一步提升至13768.8公斤\u002F公顷，实现连年增产，同时较当地传统垄作产量增幅超20%，效果显著。\n\n团队与地方政府涉农部门多方联动，围绕示范区建设、现场观摩和技术推广等开展广泛协作。下一步，将继续发挥国家重点研发计划项目的科技引领作用，完善东北黑土区耕地地力提升与减灾增效协同技术体系，扩大示范应用范围，为气候变化下黑土区抗逆增产及地力提升提供技术保障。","中国农科院农业环境与可持续发展研究所
