▍ 给植物打针有多难？比给熊孩子打针还难 先来看看植物叶子有多 "难搞"。 研究团队在论文里详细扒了植物叶子的三大防御机制：气孔开度小（ 0-20微米，比头发丝还细）、表面疏水 （自带防水涂层）、还有个特别拗口的"异质性"（heterobaricity）——简单说就是叶子内部被分隔成一个个 小房间，你往一个房间注射，液体很难扩散到其他房间。 好家伙，给植物打针这事儿，康奈尔大学的科学家们玩出花来了。 最新 登上机器人领域顶级期刊 《 Science Robotics》 封面 上的这篇论文，简直是给传统植物学研究方式 来了个降维打击 ——他们造了个软体机器人，专门给植物叶子"打针"，而且打完之后叶子基本没事儿。 这可不是闹着玩的。要知道，以前给植物叶子注射各种试剂，那叫一个惨烈：要么把整片叶子泡在溶液里（费 钱又不精准），要么用无针注射器硬怼（经常把叶子搞得千疮百孔）。 康奈尔这帮人的解决方案？用软的！ （文末有论文链接） 传统方法在这些防御面前基本都歇菜了。真空浸润法？得把整片叶子泡进去，不仅浪费试剂，还没法控制具体 注射哪里。无针注射器？在异质性强的叶子上，经常是伤口面积比注射面积还大 ——论文里有个数据特 ...

央视网消息（新闻联播）：随着西南麦区正式开镰收获，长江中下游麦区、黄淮海麦区也陆续进入收获 期，记者在采访中发现，今年各麦区的小麦收获作业效率显著提升。 小麦作业效率的提升，不仅是由于大马力农机的推广使用，也得益于更为精准、高效的跨区作业服务。 今年，河南南阳小麦收割期较往年明显提前。不少跨区农机手改变原来的收割计划，直接赶到南阳。 为了方便跨区农机手尽快收割作业，南阳将"三夏"服务台增加到64个。走访中，记者看到，在服务站， 农机手不仅可以领到包括风油精、毛巾等在内的爱心服务包，还可以获取路线推荐、农机维修和供油等 咨询服务。 为保障今年"三夏"有序开展，江苏组织各地摸底农机应急作业机具情况，同时开展集中检修保养服务， 确保农机以最佳状态投入夏收夏种。 国家精准农业应用项目数据服务平台提供的数据显示，从5月15日开始，全国小麦机械化收获重心已由 四川逐步向湖北北部、河南南部地区转移。目前，湖北已收获小麦750.3万亩，进度47.9%，同比快2.6 个百分点。 在湖北小麦主产区襄阳市采访时，记者发现，今年襄阳多家农机专业合作社都购入了大喂入量收割机， 这种喂入量达到每秒12公斤的收割机极大提升了小麦收获效率。 ...

让这些小型智慧农机真正扎根泥土，既需要技术创新突破，更需要产业链协同推进。今年中央一号文件 提出推动农机装备高质量发展，中共中央、国务院印发的《加快建设农业强国规划（2024—2035年）》 则进一步明确了加强"丘陵山区适用小型机械等农机装备和关键零部件研发应用"。 各地应继续加大政策支持，通过财政、税收、金融等措施，降低小型智慧农机的研发制造成本，构建符 合实际的小型智慧农机装备创新发展体系。还可以推进宜机化改造，以多种激励手段鼓励有条件的企 业、合作社多购置小型智慧农机，以共享租赁、加大补贴力度等方式，解决农户"无机可用""无机好 用"的窘境。 此外，企业要加强自主研发，加大技术创新投入，完善产业链，提高产品质量，降低生产成本，进一步 提升小型智慧农机智能化水平。科研机构则要加强人才培养，加快向农户普及作物生产技术，搭建"田 间课堂"，因地制宜加快小型智慧农机的普及应用，为农业高质量发展注入新动能。 （文章来源：经济日报） 在适应性上，小型智慧农机小巧灵活，能轻松穿梭于狭窄田埂、不规则地块之间，可避免大型农机"有 劲使不出"的尴尬情况。在智能化方面，小型智慧农机搭载智能传感、远程通信、北斗定位等技术，可 ...
