草地貪夜蛾再次來襲，防控技術(shù)＋植保無人機來護航

導(dǎo)讀：今年，草地貪夜蛾卷土重來，并較去年提前了1個月時間，給國家的糧食安全造成了極大威脅。

　　【農(nóng)機網(wǎng) 編輯視角】 據(jù)農(nóng)業(yè)農(nóng)村部監(jiān)測，當(dāng)前在全國22省份的1082個縣發(fā)生了草地貪夜蛾，發(fā)生北界已達黃河北岸。據(jù)了解今年草地貪夜蛾發(fā)生早，比去年提前了一個月左右，春季蟲量大、擴散快，對今年的玉米生產(chǎn)構(gòu)成較大威脅。
 
　　草地貪夜蛾相信大家已經(jīng)并不陌生了，它被稱為“糧食殺手”，是一種破壞力強、適應(yīng)力強、幾乎沒有天敵的重大害蟲，可對玉米、棉花、小麥、水稻等農(nóng)作物產(chǎn)生極強的破壞性，嚴(yán)重可導(dǎo)致顆粒無收。2018年12月，草地貪夜蛾從緬甸侵入我國云南普洱。2019年，我國22省份發(fā)現(xiàn)了草地貪夜蛾幼蟲，實際造成危害面積200多萬畝。今年，草地貪夜蛾卷土重來，并較去年提前了1個月時間，給國家的糧食安全造成了極大威脅。

       《草地貪夜蛾防控手冊》發(fā)布
 
　　今年4月9日，由中國工程院院士、中國農(nóng)業(yè)科學(xué)院副院長吳孔明牽頭撰寫的《草地貪夜蛾防控手冊》由中國農(nóng)業(yè)科學(xué)技術(shù)出版社出版發(fā)行，同時面向全國各省(自治區(qū)、直轄市)植物保護總站發(fā)布了草地貪夜蛾新防控技術(shù)。吳孔明院士在報告會上解讀了《草地貪夜蛾防控手冊》，主要內(nèi)容包括草地貪夜蛾形態(tài)特征、生活習(xí)性、發(fā)生規(guī)律、測報技術(shù)和防控措施。該書內(nèi)容翔實、圖文并茂，通俗易懂，是一本農(nóng)民能看得懂的科普讀物。
 
　　據(jù)了解，該手冊匯集了一年來針對這一重大農(nóng)業(yè)病蟲害的生物學(xué)與成災(zāi)特點、遷飛規(guī)律等的研究成果，以及在此基礎(chǔ)上研發(fā)的一整套防控技術(shù)，該技術(shù)研發(fā)形成了生產(chǎn)實用的草地貪夜蛾測報技術(shù)體系，一個是草地貪夜蛾自動識別系統(tǒng)，農(nóng)民、基層植保員用手機拍照或直接上傳圖像就能實時識別；另一個是可提供網(wǎng)絡(luò)快捷服務(wù)的草地貪夜蛾種群測報系統(tǒng)，通過提供田間調(diào)查數(shù)據(jù)預(yù)測種群發(fā)生發(fā)展動態(tài)和防治適期等。目前，部分技術(shù)和成果已在云南、廣西、四川、福建、江蘇、山東、河南等地區(qū)推廣，也指導(dǎo)了一批大中型病蟲害防治企業(yè)的生產(chǎn)，有力增強了草地貪夜蛾防控的信心。
 
　　植保無人機來護航
 
　　據(jù)農(nóng)業(yè)農(nóng)村部預(yù)測，今年下半年全國玉米病蟲害發(fā)生8.2億畝次，蟲害5.6億畝次，病害2.6億畝次。其中，草地貪夜蛾將重點危害西南、華南、江南夏秋玉米，云南、廣西等邊境地區(qū)發(fā)生較重；黃淮海、西北等地發(fā)生區(qū)域會繼續(xù)擴大，總體為點片或零星發(fā)生，發(fā)生面積為1000萬畝。
 
　　面對來勢洶洶的害蟲，農(nóng)機行業(yè)也是防控一份子。在2019 年，憑借著規(guī)模作業(yè)調(diào)度快、效率高等優(yōu)勢，很多地區(qū)的統(tǒng)防統(tǒng)治都將植保無人機選為*的防治工具，植保無人機也在“防控大戰(zhàn)”中貢獻了不少力量。

　　2019年DJI 大疆農(nóng)業(yè)聯(lián)合全國各地合作伙伴，積極參與各省市植保站、農(nóng)科院組織的防控工作，對發(fā)生蟲情區(qū)域的農(nóng)作物進行飛防作業(yè)，幫助農(nóng)戶有效滅蟲保產(chǎn)。而為了預(yù)防性地針對草地貪夜蛾帶來的危害，2020年1月初，大疆農(nóng)業(yè)在海南開啟了新一年的草地貪夜蛾防控戰(zhàn)，更吹響了全國各地的大疆植保機圍剿草地貪夜蛾的號角，隨著各地統(tǒng)防統(tǒng)治任務(wù)的增加，植保無人機的作業(yè)面積還將繼續(xù)擴大。
 
　　極飛也積極響應(yīng)農(nóng)業(yè)農(nóng)村部號召，采取有效措施防控草地貪夜蛾。以去年為例，極飛聯(lián)合了拜耳作物科學(xué)、中農(nóng)立華等合作伙伴，以廣西橫縣為首戰(zhàn)點，對蟲口密度達到 10 頭/百株的玉米田開展了應(yīng)急防控，達到98%以上的幼蟲殺死率。而早在2018年，極飛P系列植保無人機已經(jīng)在非洲市場被應(yīng)用到了草地貪夜蛾的防治。

　　結(jié)語：據(jù)悉，針對當(dāng)前草地貪夜蛾發(fā)生情況，農(nóng)業(yè)農(nóng)村部已組織各地制定防控方案，布設(shè)西南邊境、長江、黃河和長城沿線四條阻擊帶，重點地區(qū)防治兩到三遍，全力保護玉米主產(chǎn)區(qū)安全。我們也期待植保無人機在這場草地貪夜蛾防控攻堅戰(zhàn)中繼續(xù)發(fā)揮更大“戰(zhàn)斗力”，為保障農(nóng)業(yè)生產(chǎn)和國家糧食安全做出更大貢獻。
