　　【中國農(nóng)機(jī)網(wǎng) 本站原創(chuàng)】 五一小長假即將來臨，很多人都做好了出行規(guī)劃。在規(guī)劃中，天氣是不可忽視的因素之一，對于農(nóng)業(yè)來說，同樣如此。
 
　　據(jù)中國氣象網(wǎng)發(fā)布，預(yù)計五一假期期間，南方地區(qū)多降雨天氣。從30日夜間開始，西南地區(qū)東部、江漢、江淮、江南中北部等地，將自西向東先后出現(xiàn)中到大雨，江淮、江漢東部、江南北部局地將有暴雨。同時，因為大氣不穩(wěn)定，上述地區(qū)將伴有短時強降水和局地的雷暴大風(fēng)等強對流天氣。而北方地區(qū)，以多云為主。5月1日，內(nèi)蒙古東部，東北地區(qū)中南部，黃淮，華北南部有小到中雨，上述部分地區(qū)伴有雷電等強對流天氣。
 
　　29日，華北至黃淮大部地區(qū)氣溫將達(dá)29℃至30℃。30日起，冷空氣將影響中東部，北方氣溫將有所下降，降溫幅度在4-6℃左右，南方降溫不明顯，華南地區(qū)較為悶熱。
 
　　強降水天氣可能導(dǎo)致部分地區(qū)遭受洪澇災(zāi)害，低洼田塊可能因排水不暢而被淹受澇，持續(xù)陰雨天氣對冬小麥和油菜生長發(fā)育、一季稻和棉花播種不利，早稻育秧和移栽進(jìn)度也受到影響；同時陰雨寡照天氣也不利于冬小麥和油菜收獲晾曬，警惕局部地區(qū)出現(xiàn)發(fā)芽霉變現(xiàn)象；另外，多雨天氣也有可能造成烤煙、蔬菜等生長遲緩、長勢偏弱，部分農(nóng)區(qū)作物病害發(fā)生。
 
　　目前，正值冬小麥孕穗抽穗期，多降水天氣充分滿足小麥生長所需水分，但同時由于氣溫高濕度大，這段時間也是小麥病蟲害高發(fā)期，強降水天氣將加重赤霉病發(fā)生流行，對小麥安全生產(chǎn)構(gòu)成威脅。南方水稻正處于插秧期，多降雨天氣對農(nóng)民來說也會造成一定困擾。
 
　　5月，全國各地陸續(xù)進(jìn)入汛期，天氣形勢復(fù)雜多變。各地須密切監(jiān)視天氣變化，防御進(jìn)入汛期后各種災(zāi)害對農(nóng)業(yè)的影響。北方冬麥區(qū)要加強麥田后期管理，促進(jìn)冬小麥產(chǎn)量形成，同時防范階段性干旱、干熱風(fēng)，降水過后，加強病蟲害監(jiān)測防治，做好“一噴三防”工作。南方地區(qū)要做好夏收及春播作物的田間管理，加強病蟲害監(jiān)測與防治，及時移栽早稻，防御不利天氣影響，做好強降水、強對流天氣的防御工作，清溝排水工作以及溫室大棚等生產(chǎn)設(shè)施的檢修加固工作，抓住有利天氣及時移栽早稻，并做好早稻水肥管理。
