"十五五"规划建议提出，"提升农业综合生产能力和质量效益""增强粮食等重要农产品供给保障能 力"，对未来5年稳定粮食生产、确保粮食安全作出重要部署。 以农业关键核心技术攻关为引领，聚焦底盘技术、核心种源、关键农机装备等领域，加强农业与科 技融合，全面提升土地产出率、劳动生产率和农业资源利用效率，才能让国家粮食安全根基更加牢固。 如何让星罗棋布的农田，汇入现代化大农业的江河？答案在"服务"二字。过去种地，有人开春就发 愁：买种子化肥得跑断腿，雇农机手得请好几次，价格年年涨，干活还未必及时。现在好了，合作社从 种到收一条龙服务，不用出力，坐等分红。河南建成各类为农服务中心932个，全链条服务回应农户需 求；广东加快培育区域农机社会化服务中心，提升农机化生产和应急服务能力……这些因地制宜的探 索，离不开完善的制度保障与精准的政策支持。加快构建新型农业社会化服务体系，才能让各类服务主 体有信心、有动力，让广大农户得实惠、享便利。 解决好吃饭问题始终是我们党治国理政的头等大事。解决吃饭问题，不能光盯着有限的耕地，要把 思路打开。在黑土地喜获五谷丰登，从林海探寻山珍百味，于广袤河湖见证鱼虾满舱……黑龙江打造践 行大食物观 ...

"十四五"时期，种业科技创新整体进入世界第一方阵。构建了多层次立体式育种创新攻关体系。培育出高抗赤霉病小麦、抗稻飞虱 水稻、耐密宜机收玉米、耐除草剂高油高产大豆等一批重大新品种。 央视网消息：农业现代化，种子是基础。记者11月14日从农业农村部了解到，"十四五"时期，我国启动种业振兴行动，目前，阶段 性任务顺利完成。 "十四五"时期，农业种质资源"家底"更加厚实。我国完成新中国成立以来规模最大、覆盖范围最广的全国农业种质资源普查，摸清 了资源"家底"，并建成国际一流的农作物、畜禽、海洋渔业三大国家种质库，资源保存总量跃居世界第一。 "十四五"时期，种业基地供种能力明显增强。以甘肃玉米、四川水稻、黑龙江大豆、海南南繁四大国家级育制种基地为核心的良种 繁育"国家队"基本形成。目前，国家级种业基地供种保障率达到80%，比2020年提高10个百分点。 种业振兴行动启动五年来，目前，我国种源安全水平稳步提升，农作物自主选育品种占比95%以上，畜禽、水产国产种源市场占有 率分别超过80%和85%。农业用种安全总体有保障、风险可管控的态势更加牢固。 ...
