新华社成都10月6日电 金秋时节，川蜀大地水稻金黄、蔬果飘香，田间地头处处是丰收的景象。 然而，四川的地理特征是"一平二坡七分山"，盆地丘陵和盆周山区也是粮食生产的重要区域，粮食产量 占四川粮食总产量的四分之三以上。"除了成都平原，改造升级丘陵地区的土地，对提升粮食产量十分 重要。"四川省农业农村厅相关负责人说。 作为种业大省，"十四五"期间，四川将种业振兴作为打造新时代更高水平"天府粮仓"的关键支撑。从加 强种质资源保护和利用，到强化供种保障，再到培育壮大种业领军企业，产业生态培育和全链条协同发 展，四川正加快实施种业振兴行动，向建设中国西南种业中心的核心目标加速推进。 在成都邛崃市的天府现代种业园，植保无人机、墒情监测仪等装备全方位"看护"各种水稻新品种。据介 绍，自2018年成立以来，园区搭建起"一库一院五中心"重大功能平台，包括省级综合性种质资源中心 库、四川现代种业研究院、国家品种测试西南分中心等，成为资源保护、科研攻关、企业孵化、成果转 化的重要载体。 有了良种，还必须有良田作为基础，才能实现丰产、增产。记者在四川多地农村看到，田成方、渠成 网、路相通、沟相连的高标准农田，成为越来越常见的"良田美 ...

Core Viewpoint - The development of regenerative rice is becoming a key player in stabilizing grain production and increasing farmers' income, supported by modern agricultural technology [1][3].
