導(dǎo)讀：近日，在農(nóng)業(yè)農(nóng)村部種植業(yè)管理司統(tǒng)一指導(dǎo)下，全國農(nóng)技中心組織農(nóng)業(yè)農(nóng)村部油菜專家指導(dǎo)組和12個油菜主產(chǎn)省農(nóng)技部門，分區(qū)域、分階段開展油菜中后期田間管理專家包省包片技術(shù)指導(dǎo)工作

　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 當(dāng)前，油菜已大面積進(jìn)入越冬期。主產(chǎn)區(qū)氣溫偏高、降水偏少，部分地區(qū)油菜出現(xiàn)干旱脫肥、苗情兩極分化情況，增加了油菜越冬風(fēng)險，對夏收豐產(chǎn)造成不利影響。近日，在農(nóng)業(yè)農(nóng)村部種植業(yè)管理司統(tǒng)一指導(dǎo)下，全國農(nóng)技中心組織農(nóng)業(yè)農(nóng)村部油菜專家指導(dǎo)組和12個油菜主產(chǎn)省農(nóng)技部門，分區(qū)域、分階段開展油菜中后期田間管理專家包省包片技術(shù)指導(dǎo)工作，及時了解油菜苗情長勢以及墑情、病蟲情、災(zāi)情，指導(dǎo)各地落實落細(xì)各項田間管理技術(shù)措施，夯實油菜大面積單產(chǎn)提升基礎(chǔ)。
 
　　指導(dǎo)組分長江中游、長江下游和西南三個片區(qū)，每個片區(qū)不少于10名科研和推廣專家。將采用集中指導(dǎo)與分散指導(dǎo)、面上調(diào)度與點上了解、集中會商報告與隨時反映情況三個結(jié)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(zāi)情，分析研判各類病蟲災(zāi)情的影響和發(fā)生發(fā)展趨勢。二是指導(dǎo)各地加強(qiáng)災(zāi)害預(yù)防，統(tǒng)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(shù)措施。三是了解各地抓油菜生產(chǎn)工作經(jīng)驗做法，反映困難問題，提出對策建議。
 
　　指導(dǎo)活動將結(jié)合常年油菜生長生育期和關(guān)鍵田管期分成四個階段。第一階段從元旦至立春，重點關(guān)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(guān)注防凍害、防倒伏、早薹早花，巧施薹肥，注意增施鉀肥增強(qiáng)莖桿強(qiáng)度；第三階段從驚蟄至清明，重點關(guān)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(guān)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(jī)收減損。
