藏粮于地：盐碱地破"碱"重生 盐碱地既是亟待唤醒的耕地后备资源，更是保障粮食安全的"潜在粮仓"。山东拥有的近900万亩盐碱 地，使其成为探索盐碱地治理路径的"天然试验场"。 从"靠天吃饭"到筑牢"齐鲁粮仓" 山东用"芯"端稳饭碗 中新网济南9月25日电(李欣 李明芮 孙婷婷)从与黄河三角洲盐碱荒滩艰苦博弈，到在一粒种子间寻求关 键突破，再到向产业链全程要效益、挖掘"无形良田"，山东保障粮食安全的步履沉稳而有力，系统性筑 牢"齐鲁粮仓"。这条从"靠天吃饭"到"科技赋能"的扎实路径，彰显了山东作为农业大省的担当。 "春天白茫茫，夏天水汪汪，十年九不收，糠菜半年粮！"黄河入海口流传的这句顺口溜，曾是农民与盐 碱地抗争的苦涩注脚，也凸显了盐碱地治理的困境。 如今，盐碱地的命运正被改写。山东省农业农村厅副厅长王敬东介绍，山东将盐碱地综合利用纳入黄河 重大国家战略，探索出一条"生态优先、因地制宜、种地相适、多元利用、科技支撑"的盐碱地综合利用 新路径。 2025年6月，在东营市东营区辛店街道唐家村股份经济合作社盐碱地麦田，农机手驾驶收割机抢收 小麦。刘智峰 摄 循着分区分类的治理思路，山东为不同区域量身定制土壤改良、地力 ...
