导读:近日,在农业农村部种植业管理司统一指导下,全国农技中心组织农业农村部油菜专家指导组和12个油菜主产省农技部门,分区域、分阶段开展油菜中后期田间管理专家包省包片技术指导工作
【农机网 科技创新】 当前,油菜已大面积进入越冬期。主产区气温偏高、降水偏少,部分地区油菜出现干旱脱肥、苗情两极分化情况,增加了油菜越冬风险,对夏收丰产造成不利影响。近日,在农业农村部种植业管理司统一指导下,全国农技中心组织农业农村部油菜专家指导组和12个油菜主产省农技部门,分区域、分阶段开展油菜中后期田间管理专家包省包片技术指导工作,及时了解油菜苗情长势以及墒情、病虫情、灾情,指导各地落实落细各项田间管理技术措施,夯实油菜大面积单产提升基础。
指导组分长江中游、长江下游和西南三个片区,每个片区不少于10名科研和推广专家。将采用集中指导与分散指导、面上调度与点上了解、集中会商报告与随时反映情况三个结合的方式,重点做好三个方面的工作:一是深入田间地头了解油菜苗情和各类病虫灾情,分析研判各类病虫灾情的影响和发生发展趋势。二是指导各地加强灾害预防,统筹肥水管理,狠抓抗旱防冻、控旺促弱、防治病虫等田间管理技术措施。三是了解各地抓油菜生产工作经验做法,反映困难问题,提出对策建议。
指导活动将结合常年油菜生长生育期和关键田管期分成四个阶段。第一阶段从元旦至立春,重点关注冻害问题,注意冬灌和腊肥施用;第二阶段从立春至惊蛰,重点关注防冻害、防倒伏、早薹早花,巧施薹肥,注意增施钾肥增强茎杆强度;第三阶段从惊蛰至清明,重点关注倒春寒、菌核病危害,注意做好一促四防;第四阶段从清明至收获,重点关注角果性能防早衰、增加千粒重,注意搞好一促四防并适期机收减损。
