導(dǎo)讀：近日，全國農(nóng)技中心組織6月全國花生生產(chǎn)技術(shù)會商會，分析當(dāng)前各主產(chǎn)區(qū)花生生產(chǎn)有利、不利因素，提出今后一個月生產(chǎn)管理主要技術(shù)措施。

　　【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】 近日，全國農(nóng)技中心組織6月全國花生生產(chǎn)技術(shù)會商會，分析當(dāng)前各主產(chǎn)區(qū)花生生產(chǎn)有利、不利因素，提出今后一個月生產(chǎn)管理主要技術(shù)措施。農(nóng)業(yè)農(nóng)村部花生專家指導(dǎo)組有關(guān)專家及花生主產(chǎn)省省級農(nóng)技推廣部門技術(shù)骨干等20余人參加會商。
 
　　當(dāng)前，各產(chǎn)區(qū)花生處于不同生長階段，長勢不一。東北產(chǎn)區(qū)春花生處于始花期，近期降雨正常偏多，花生苗情和田間長勢整體較好。黃淮、長江流域產(chǎn)區(qū)春花生、麥套花生分別處于下針期、盛花期，夏直播花生播種完畢，陸續(xù)進(jìn)入出苗期和幼苗期，6月以來整體降雨偏少，對夏花生播種和春花生生長不利，夏花生出苗率和出苗質(zhì)量一般，春花生苗情和長勢較常年偏弱。華南產(chǎn)區(qū)春花生處于飽果期，降雨偏多，局部形成澇害和漬害。
 
　　當(dāng)前和今后一個月花生生產(chǎn)有利和不利因素并存。東北產(chǎn)區(qū)降雨總體比常年偏多2—3成，土壤墑情好，利于花生生長，但易造成花生田間澇漬以及果腐病等土傳病害發(fā)生。預(yù)計黃淮、長江流域產(chǎn)區(qū)7月上中旬降雨充足，利于夏花生苗期生長，但也易造成田間澇漬、春花生徒長、夏花生田間除草困難等；同時，丘陵旱坡地等不具有灌溉條件的田塊易受7月中下旬高溫干旱天氣影響。華南產(chǎn)區(qū)正處于“龍頭水”汛期，高溫多雨，易造成漬害和澇害，不利于春花生收獲和秋花生播種。
 
　　各地要密切關(guān)注天氣變化情況，統(tǒng)籌搞好田間管理，及早做好預(yù)警和應(yīng)對技術(shù)預(yù)案，降低高溫、干旱、澇害、病蟲害等帶來的損失，防災(zāi)減災(zāi)，提質(zhì)增產(chǎn)。東北產(chǎn)區(qū)要及時中耕培土，排水防漬，提高果針入土率，噴施葉面肥增強(qiáng)花生植株抗逆能力，噴施殺菌劑防控莖腐病、白絹病等。黃淮海產(chǎn)區(qū)夏花生要及時查苗補(bǔ)種，選用精喹禾靈+乙羧氟草醚+滅草松進(jìn)行苗后除草，葉面噴施蕓苔素內(nèi)酯和葉面肥以提苗、壯苗和促花，春花生要及時防治根腐病、葉螨、薊馬、蚜蟲等；旺長的春花生和麥套花生，要及時噴施烯效唑、調(diào)環(huán)酸鈣，防止倒伏、促進(jìn)莢果膨大；近期要密切關(guān)注天氣變化，防范旱澇急轉(zhuǎn)。長江流域產(chǎn)區(qū)要同時做好抗旱、防汛田間管理，夏播花生要及時查苗補(bǔ)苗、盡早除草，苗弱和受除草劑影響的田塊可噴施磷酸二氫鉀以促進(jìn)根系發(fā)育和植株生長；春花生生長過旺時應(yīng)及時化控，使用噻呋酰胺提前預(yù)防白絹病。華南產(chǎn)區(qū)7月處于春花生收獲期，降雨較多，田間積水時應(yīng)及時疏通排水溝，盡快排干田間積水，搶晴天及時收獲和晾曬，搶收上市。
