然而，盐碱滩上育种，难度很大。 近日，记者在山东省滨州市采访时发现，从田间"出发"的一粒小麦，"走过"加工流水线，能"变身"600 多种产品。这个故事，从一片曾经荒芜的盐碱地开始，走出了一条科技赋能、全链增值、反哺土地的路 径。 从"一粒种"到"万亩田"—— 定向培优促丰产增收 在滨州市滨城区肖家村的田野里，村民肖军正在劳作。这片土地冬夏种小麦，秋天种玉米，今年夏收小 麦亩产近1200斤。然而十几年前，这里的景象截然不同。"搁以前，这片地的苗稀稀拉拉，风一吹就趴 窝；有的地块碱泛得厉害，苗都枯死了。"肖军回忆。 滨州有120多万亩盐碱地，如今"不毛之地"变良田，靠啥？ "不仅要改地，更要从根源上寻突破——选育耐盐碱品种适应盐碱地。"滨州中裕食品有限公司育种研发 中心主任李恒钊说。 "头一道难关，就是盐碱地'脾气'难捉摸。即使是同一块地，其盐碱度也不一样，拿普通种子在这儿 试，如同盲人摸象。"李恒钊说。 李恒钊和团队另辟蹊径，将选育的种子种在人工模拟的盐碱池里，在一次次人工配比的"咸水浴"中进行 定向培优。"这就像练兵选将，只留下那些挺过盐碱'拷打'的硬骨头，逼着种子们不断'强筋壮骨'。"李 恒钊说。 2023 ...
