53](https:\u002F\u002Fp3.img.cntv.cn\u002Fphotoworkspace\u002Fcontentimg\u002F2026\u002F09\u002F20\u002F2026092013212476326.png)\n\n在果蔬成果展区，最受欢迎的不是常见的香甜水果，而是一杯胡萝卜汁。  \n  \n 科研人员通过调节不同品种胡萝卜的收获时间和栽培模式，培育出口感更甜更细腻的品种以及减糖版胡萝卜。  \n  \n 中国农业科学院蔬菜花卉研究所大宗蔬菜产业技术体系岗位专家庄飞云介绍，胡萝卜口感整体受环境影响特别大，通过调节里面的一些组分，很多让人不愉快的组分把它尽量减少到很低，当然它的营养还能保持原有的营养。\n\n![Image 54](https:\u002F\u002Fp5.img.cntv.cn\u002Fphotoworkspace\u002Fcontentimg\u002F2026\u002F09\u002F20\u002F2026092013213274797.png)\n\n另一边的展区里，这种晶莹剔透的黄瓜不仅口感脆嫩，还富含一种能有效阻止糖类转化为脂肪的功能小分子——“丙醇二酸”。吃根黄瓜还能顺带帮着管理体重。  \n  \n 作物展区里，作物科学研究所带来了新的攻关成果。低豆腥味、高异黄酮、适合榨汁的大豆，还有一款新研发的“甜糯同粒”玉米。\n\n![Image 55](https:\u002F\u002Fnews.cctv.cn\u002F2026\u002F09\u002F20\u002FARTIkUEnHV7gFcVPFEweSMwS260920.shtml)\n\n中国农业科学院作物科学研究所育种专家肖永贵介绍，原来的玉米要么是甜，要么是糯，要么就是7粒糯1粒甜，要么3粒糯1粒甜，把甜和糯放到一个粒里按照不同比例调配口感会更好。  \n  \n 机械展区，各种新型农用机器人集体亮相。这台农业转运机器人不仅能扛100公斤以上的作物在丘陵山区跑，还会“凌波微步”。\n\n![Image

正在研发的全球动物疾病风险大模型，未来将对动物疫病实现实时预报预警，相当于给全球畜牧业装上一张“天气图”，让餐桌上的肉蛋奶更安全。从吃到用，实验室与餐桌的距离正在被这些“看得见、尝得到、用得上”的成果不断拉近。\n\n编辑：杨书杰 责任编辑：刘亮\n\n*
