中新网重庆11月25日电 题：冬日农事忙 中国"西部菜都"新农人辈出 作者 张旭 制作冰块给豌豆尖(豌豆植物幼苗顶端的嫩茎叶)保鲜、操作无人机给大片"包包白"(甘蓝)做植保、为考 取"农民高级技师"提升学历……近日，中新网记者走进有中国"西部菜都"之称的重庆潼南，在冬日农事 的忙碌中，感受到"新农人"辈出的勃勃生机。 冬意渐浓，豌豆尖再次成为川渝民众餐桌上的"顶流"。其口感清香爽口，下面条、炒菜、烫火锅皆可。 从事农业前，代宏春只有高中学历，从事农业后，他就读于四川农业大学提升学历，并获得"农民高级 技师"职称。 代宏春说，自2011年投身农业后，就以此为主业。不过，他的从农之路并非一帆风顺，也曾因为对市场 不够了解，盲目投入导致亏本，一度亏损70余万元人民币。此后，经过一番摸爬滚打，他才扭亏为盈。 虽然历经风雨，代宏春仍然觉得，现代农业是有魅力的，值得年轻人全情投入。 图为11月7日航拍重庆市北碚区金刀峡镇的一处特色汤锅经营场所。该汤锅位于菜地旁，可实现豌豆尖 等菜肴从田间到餐桌"零距离"销售。张旭 摄 "今年，豌豆尖等'绿叶菜'的市场行情走俏。"潼南区新胜镇钟峰村村民龚先锋说，这跟菜品品种、品 质、生长周 ...

早上8点，青海省西宁市湟中区共和镇上直沟村的蔬菜基地里已是一派繁忙景象。56岁的祁如英和同伴 们正麻利地收割着最后一茬菠菜。 "一天能挣200元，家里零花不愁了。"祁如英说，她所在的这个基地，5年前还是一片闲置土地，如今已 成为带动村民增收的"聚宝盆"。 位于青藏高原东北部的湟中区，平均海拔超2600米，高寒缺氧的气候制约着当地农业发展。然而，随着 冷凉蔬菜产业兴起，这种劣势正在转化为独特优势。近年来，湟中区充分利用高原冷凉气候和洁净环 境，走出一条利用蔬菜产业带动农民增收、促进乡村振兴的特色之路。 科技创新为湟中冷凉蔬菜产业注入了强大动力。在湟中龙财种养殖专业合作社的基地里，负责人钟光言 正在检查水肥一体化系统的运行情况，"2018年我们开始规模化种植，从300亩发展到现在的1700亩。政 府的技术支持让我们如虎添翼，以前六七个人一天只能浇10亩地，现在一个人就能浇30亩"。 然而，发展之路并非一帆风顺。"销售渠道和冷链运输的短板仍然制约着产业发展。"胡建坤说。对此， 2018年以来，班仲营村创新采用"党支部+龙头企业+协会"的经营模式，配套建设了3600吨保鲜库和 5000平方米蔬菜分级分拣配送中心，既满 ...
