"平均亩产1209.1公斤，这标志着全国首个两百万亩玉米'吨粮田'成功创建。"金秋时节，新疆伊犁哈萨 克自治州传来喜讯。这一纪录的诞生，离不开中国农业科学院研发的"玉米密植高产精准调控技术"支 撑。依托该技术，位于伊犁的200余万亩玉米高产田亩保苗株数从传统的不足5000株提升到7000—8000 株，玉米收获穗数大幅提升。 这只是我国科技强农、粮食增产增收的一个缩影。"十四五"以来，我国粮食总产量始终保持在1.3万亿 斤以上。2024年粮食总产量更是首次突破1.4万亿斤，比2020年增产740亿斤。 习近平总书记强调，发展现代农业，建设农业强国，必须依靠科技进步，让科技为农业现代化插上腾飞 的翅膀。 "十四五"规划提出，完善农业科技创新体系，创新农技推广服务方式，建设智慧农业。5年来，在科技 创新的强劲支撑下，14亿人的饭碗端得更牢、农业现代化水平显著提升、产业新动能持续增强，农业强 国建设迈上新台阶。 科技铸"芯"，夯实大国粮仓之基 国以农为本，农以种为先，种子被誉为农业的"芯片"。前不久，四川省富顺县水稻百亩超高产攻关片进 行实割实测，再生稻亩产达到494.81公斤，加上此前测产中稻亩产807.13公斤 ...
