气象部门数据显示，2月13日，成都就正式进入气象学意义上的春天，比常年提前18天。目前，四 川盆地大部分城市已经入春。 □四川日报全媒体记者 张彧希 行晓艺 2月26日，宜宾市筠连县筠连镇柏杨村，种植户陶垠玲家的几十亩油菜长势喜人，"这几天天气 好，油菜也长得特别好。"不只陶垠玲，最近，当地许多农户都忙着平秧田、买谷种，而往年这些 准备工作都要到农历正月十五之后才开始。 "早到"的春天，会对农业生产带来哪些影响？"目前看来影响不大。"眉山市东坡区太和镇永丰村 种粮大户王海聪说。他这几天正忙着收割地里栽种的青菜，计划3月5日开始育秧，4月中下旬开始 插秧，"这个时间和往年差不多。" 对此，农业专家提醒广大农户，抓紧利用近期晴好天气做好土地备耕和保墒工作，同时建议采取 地膜覆盖等技术，降低倒春寒的影响。若持续气温偏高，小春作物（小麦、油菜）生育进程将加 快，要做好水稻早栽、玉米早播的准备。 "由于现在还处于备耕阶段，直接影响不明显，但间接影响不能不重视。"四川省农业科学院作物 研究所研究员杨勤说，一方面，刚刚过去的暖冬气候偏干，为越冬病虫害提供了"温床"，过冬虫 卵的基数较大，因此今年可能病虫害偏重，要注意防治； ...

夜晚是各种设备捕虫的高峰期。次日清晨，则是张浩文和团队的"收虫"时刻。他们小心翼翼地将诱杀灯 下的害虫分类、计数，斜纹夜蛾、粘虫、甜菜夜蛾……这些对农作物破坏力极强的迁飞性害虫，被一一 记录在统计表中。"这些数据是摸清害虫迁飞规律的关键。"张浩文说，经过四年积累，团队已经掌握了 不同害虫的发生高峰，为精准防治提供了重要依据。 在基地的一角，一台集成了灯诱、性诱、电网等功能于一体的智能化监测装置格外引人注目。"这是我 们新研发的设备，有了它我们可以远程掌握降落在这片田的害虫动态。"张浩文介绍，相较于传统装 置，这个"多面手"不仅能通过多种方式诱捕害虫，还能通过内置的智能传感器和图像识别芯片，自动完 成害虫的数量和种类识别，数据实时同步到云端平台。 原标题：新春走基层｜"虫子飞到哪，我们的监测和研究就跟到哪" "这个时候北方天寒地冻，虫子都冬眠了，或者迁飞到南方了，三亚就成了我们的'主战场'。"腊月时 节，冷空气席卷北国，而海南三亚的田间地头却依旧绿意盎然。在中国农业科学院国家南繁研究院的东 南亚迁飞性害虫监测预警与防控技术研究基地里，两台探虫雷达与错落分布的监测装置、诱杀灯等组成 了一道特殊的"防线"。 中国农 ...
