【農機網 科技創新】 當前，油菜已大面積進入越冬期。主產區氣溫偏高、降水偏少，部分地區油菜出現干旱脫肥、苗情兩極分化情況，增加了油菜越冬風險，對夏收豐產造成不利影響。近日，在農業農村部種植業管理司統一指導下，全國農技中心組織農業農村部油菜專家指導組和12個油菜主產省農技部門，分區域、分階段開展油菜中后期田間管理專家包省包片技術指導工作，及時了解油菜苗情長勢以及墑情、病蟲情、災情，指導各地落實落細各項田間管理技術措施，夯實油菜大面積單產提升基礎。
指導組分長江中游、長江下游和西南三個片區，每個片區不少于10名科研和推廣專家。將采用集中指導與分散指導、面上調度與點上了解、集中會商報告與隨時反映情況三個結合的方式，重點做好三個方面的工作：一是深入田間地頭了解油菜苗情和各類病蟲災情，分析研判各類病蟲災情的影響和發生發展趨勢。二是指導各地加強災害預防，統籌肥水管理，狠抓抗旱防凍、控旺促弱、防治病蟲等田間管理技術措施。三是了解各地抓油菜生產工作經驗做法，反映困難問題，提出對策建議。
指導活動將結合常年油菜生長生育期和關鍵田管期分成四個階段。第一階段從元旦至立春，重點關注凍害問題，注意冬灌和臘肥施用；第二階段從立春至驚蟄，重點關注防凍害、防倒伏、早薹早花，巧施薹肥，注意增施鉀肥增強莖桿強度；第三階段從驚蟄至清明，重點關注倒春寒、菌核病危害，注意做好一促四防；第四階段從清明至收獲，重點關注角果性能防早衰、增加千粒重，注意搞好一促四防并適期機收減損。
