全國各地掀起春管熱潮

　　【農(nóng)機網(wǎng) 熱點關注】農(nóng)諺講“驚蟄麥返青，農(nóng)夫閑轉忙”。目前，江蘇、安徽等地小麥陸續(xù)開始起身拔節(jié)，河南、山東、山西、陜西等地小麥已全面返青，河北除北部唐山、保定、廊坊外也大面積返青，進入春季田間管理關鍵時期。各地因苗因墑推進分類田管，科學追施返青肥、澆灌返青水，迅速掀起春季田管熱潮。
 
　　近期，農(nóng)業(yè)農(nóng)村部組織各級農(nóng)技人員查苗情、查墑情、查蟲情，據(jù)專家分析，全國冬小麥長勢總體較好，好于大面積晚播的上年，也好于常年。河北、山東、陜西等地前期受寒旱疊加等因素影響，一些小麥葉片出現(xiàn)枯黃，但經(jīng)過實地查看，絕大部分小麥生長點和根系未受影響，隨著氣溫回暖已經(jīng)返青，可逐步恢復正常。
 
　　現(xiàn)在距冬小麥大面積收獲還有3個月左右，奪取豐收還要過春旱、“倒春寒”、“干熱風”、倒伏、病蟲害等關口。據(jù)氣象部門預測，春季北方冬麥區(qū)大部降水偏少，華北、膠東半島等地可能出現(xiàn)春旱，氣溫起伏大、“倒春寒”“干熱風”等災害風險較高，同時小麥條銹病、赤霉病等重大病蟲害可能偏重發(fā)生。針對這一情況，農(nóng)業(yè)農(nóng)村部牢固樹立抗災奪豐收的思想，正組織各地毫不放松抓好春季田間管理，努力贏得夏糧豐收主動權。
 
　　一是加強分類管理。對三類弱苗和受凍麥田，抓住返青起身期，增施肥促苗早發(fā)快長；對旺長麥田，推遲肥水、適當鎮(zhèn)壓；對一二類苗，堅持促控結合，肥水后移至拔節(jié)期，保苗穩(wěn)健生長。
 
　　二是狠抓防災減災。密切關注天氣變化，及時發(fā)布預警信息，提早做好抗旱、防“倒春寒”各項準備工作。抓好小麥條銹病、赤霉病等重大病蟲害監(jiān)測防控，大力推廣統(tǒng)防統(tǒng)治，減輕病蟲危害。
 
　　三是加強技術指導。發(fā)揮科技小分隊作用，組織專家駐縣駐鄉(xiāng)、進村入戶，深入田間地頭查苗情、查墑情，開展巡回指導。繼續(xù)開展冬小麥田間管理大培訓，通過《春耕大師課》等在線指導答疑，落實春季田管關鍵措施。
