評(píng)論
導(dǎo)讀:為加快調(diào)優(yōu)玉米群體結(jié)構(gòu),夯實(shí)防災(zāi)減災(zāi)和豐產(chǎn)基礎(chǔ),農(nóng)業(yè)農(nóng)村部玉米專家指導(dǎo)組會(huì)同全國農(nóng)業(yè)技術(shù)推廣服務(wù)中心以“優(yōu)化肥水、一噴多促、促控結(jié)合、統(tǒng)防統(tǒng)治”為重點(diǎn),提出當(dāng)前玉米防災(zāi)減損促豐收生產(chǎn)技術(shù)意見。
【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】 當(dāng)前,北方主產(chǎn)區(qū)春玉米多處于小喇叭口至大喇叭口期,局部受早春干旱、前期漬澇等影響導(dǎo)致生育期推遲;黃淮海夏播玉米已進(jìn)入出苗和苗期階段,由于播期遭遇高溫干旱,苗情復(fù)雜;西南春玉米進(jìn)入灌漿期、夏玉米進(jìn)入拔節(jié)期,低洼地塊受陰雨漬澇影響出現(xiàn)倒伏。近期東北氣溫回升較快,主雨帶北抬,黃淮海地區(qū)降雨明顯增多、南方降雨間歇,氣象形勢(shì)總體有利于玉米生長。為加快調(diào)優(yōu)玉米群體結(jié)構(gòu),夯實(shí)防災(zāi)減災(zāi)和豐產(chǎn)基礎(chǔ),農(nóng)業(yè)農(nóng)村部玉米專家指導(dǎo)組會(huì)同全國農(nóng)業(yè)技術(shù)推廣服務(wù)中心以“優(yōu)化肥水、一噴多促、促控結(jié)合、統(tǒng)防統(tǒng)治”為重點(diǎn),提出當(dāng)前玉米防災(zāi)減損促豐收生產(chǎn)技術(shù)意見。
南方排漬澇促灌漿
綜合施策保產(chǎn)
多雨漬澇風(fēng)險(xiǎn)較高地區(qū),按照梯次漸深原則開好廂溝、腰溝、圍溝等田間“三溝”,及時(shí)清溝理渠,保障溝系排澇暢通。低洼積水地塊,迅速組織人力、物力,采取深挖擴(kuò)容、清淤除障等疏浚措施加快排水;不具備挖溝條件的,架設(shè)水泵,采取強(qiáng)排措施,減少玉米水淹時(shí)間。對(duì)灌漿成熟期遇多雨倒伏的春玉米田視情況墊扶,有條件的可待玉米完全成熟選晴好天氣及時(shí)收獲并烘干;淹水嚴(yán)重田塊可提前收割、避雨立稈堆放,促進(jìn)植株?duì)I養(yǎng)加快轉(zhuǎn)移到籽粒;對(duì)遭遇極端災(zāi)害難以形成籽粒的適時(shí)青貯,減少損失。對(duì)尚在拔節(jié)期的夏玉米視情況補(bǔ)施3—5公斤/畝花粒肥,增加養(yǎng)分供應(yīng)。
北方搶積溫促生長
因苗因地管理
受低溫內(nèi)澇影響較重的弱苗地塊,或“黃苗”“紫苗”等生長不良地塊,酌情追施尿素等速效肥料或噴施磷酸二氫鉀、氨基酸、蕓苔素等葉面肥和生長調(diào)節(jié)劑,促弱轉(zhuǎn)壯,加快植株恢復(fù)生長發(fā)育;有條件地區(qū)利用晴好天氣加快中耕作業(yè),破除土壤板結(jié),疏松土壤,散墑增溫,增強(qiáng)土壤透氣性,并根據(jù)實(shí)際情況培土。根據(jù)土壤肥力、植株長勢(shì)、前期肥料施用方法等,在小喇叭口期至開花期采用水肥一體化或高架
追肥機(jī)等追肥,補(bǔ)充植株所需養(yǎng)分,有條件的推廣應(yīng)用“一噴多促”技術(shù),增強(qiáng)群體抗逆應(yīng)災(zāi)能力。密植地塊、長勢(shì)偏旺地塊以及風(fēng)口地區(qū)、風(fēng)災(zāi)頻發(fā)區(qū)域,在玉米6—8展葉期噴施化控劑,降低株高、塑造抗倒株型;生長過旺的做好10—12展葉期化控,調(diào)優(yōu)群體結(jié)構(gòu)。生育進(jìn)程推遲明顯的,后期視情況采取葉面噴肥和站稈扒皮等措施,促進(jìn)籽粒早熟。
夏季防高溫抗干旱
提前做好應(yīng)對(duì)
提前制定災(zāi)害應(yīng)對(duì)預(yù)案,及早儲(chǔ)備應(yīng)急救災(zāi)農(nóng)資裝備,謹(jǐn)防玉米關(guān)鍵生育期遭遇高溫?zé)岷透邷馗珊弹B加影響。如遇旱及時(shí)澆水,因地制宜推廣滴灌、壟灌、微噴灌等節(jié)水灌溉措施,因時(shí)因地噴施抗旱劑、葉面肥,增強(qiáng)玉米抗旱能力。開花吐絲期如遇高溫視情況灌水補(bǔ)墑,有條件的可使用無人機(jī)輔助授粉,提高結(jié)實(shí)率。黃淮海夏玉米區(qū)因旱缺苗較多的,視情況補(bǔ)種或毀種重播,選擇中早熟品種7月上旬完成播種;時(shí)刻關(guān)注玉米出苗后苗情旱情,及時(shí)做好二次灌溉準(zhǔn)備。
強(qiáng)化病蟲草害防控
做好統(tǒng)防統(tǒng)治
對(duì)尚未拔節(jié)玉米田,在玉米3—5葉期、雜草2—4葉期選擇合適除草劑化學(xué)除草,嚴(yán)格用藥劑量,在上午9時(shí)前或下午5時(shí)后的無風(fēng)天氣進(jìn)行噴藥,避開中午高溫時(shí)段,謹(jǐn)防藥害。大部分田塊玉米已超過5片可見葉,雨后高溫田間雜草較多的地塊,需注意選擇安全藥劑,并嚴(yán)格按照說明書控制藥量,及早除草。加強(qiáng)玉米病蟲害監(jiān)測(cè)預(yù)警,近期重點(diǎn)關(guān)注北方春玉米大斑病、炭疽病、二代粘蟲、玉米螟等,黃淮海地區(qū)甜菜夜蛾、薊馬、褐斑病、頂腐等,西南和南方地區(qū)灰斑病、白斑病、莖腐病、草地貪夜蛾等病蟲害,及時(shí)開展綠色防控和統(tǒng)防統(tǒng)治。
