大范圍降水，小麥發(fā)芽態(tài)勢嚴(yán)重

2018-05-29 16:54:54 來源：中國農(nóng)機(jī)網(wǎng)整理發(fā)布 閱讀量：29720 評論

　　【中國農(nóng)機(jī)網(wǎng) 市場行情】近日，賬號為@孤獨(dú)隨緣的用戶在中國農(nóng)機(jī)網(wǎng)公眾號后臺留言：“今年的小麥?zhǔn)粘刹缓昧耍加醒苛恕?rdquo;
 
　　都說“小滿小滿，麥粒漸滿”，豐富的降水似乎總是寓意著秋季的豐收，然而，連續(xù)性的強(qiáng)降水，夾以雷暴大風(fēng)等強(qiáng)對流天氣卻讓農(nóng)民們苦不堪言，多地出現(xiàn)了小麥倒伏，麥穗發(fā)黑、發(fā)霉、出芽等情況。
 

        全國大規(guī)模小麥跨區(qū)機(jī)收全面展開
 
　　小滿的到來意味著全方地區(qū)麥類等夏熟作物籽粒已開始飽滿，目前我國的大規(guī)模小麥跨區(qū)機(jī)收已經(jīng)全面展開。
 
　　據(jù)農(nóng)業(yè)農(nóng)村部統(tǒng)計(jì)，截至5月28日，全國已收獲小麥3260萬畝，日機(jī)收面積超過400萬畝，標(biāo)志著全國“三夏”大規(guī)模小麥跨區(qū)機(jī)收大會戰(zhàn)全面啟動(dòng)。然而，收獲過程卻并不是一帆風(fēng)順的。
 
　　強(qiáng)降雨、強(qiáng)對流天氣導(dǎo)致夏收受阻
 
　　雖然我國農(nóng)業(yè)現(xiàn)代化進(jìn)程不斷加快，機(jī)收作業(yè)更是有利于提高作業(yè)效率，解放勞動(dòng)力。但是，不可否認(rèn)的是天氣依然是在農(nóng)業(yè)勞作中占據(jù)重要地位，而頻繁的強(qiáng)降雨及強(qiáng)對流天氣對于成熟期的小麥來說無疑是給出了致命一擊。
 
　　據(jù)中央氣象臺消息，5月中旬以來，我國華北南部、黃淮及長江中下游等冬小麥、油菜產(chǎn)區(qū)降雨過程頻繁，累計(jì)降水量普遍超過50毫米，河南南部、湖北西部和東南部、安徽大部、江蘇中南部有100～300毫米，較常年同期偏多8成至2倍；期間，河北中南部、山東、河南、安徽、江蘇等地出現(xiàn)7～9級雷暴大風(fēng)和局地冰雹等強(qiáng)對流天氣。部分地區(qū)油菜、冬小麥灌漿成熟受到不利影響，低洼農(nóng)田出現(xiàn)漬澇，局地冬小麥出現(xiàn)倒伏。
 
　　未來氣象條件總體利于夏收大面積開展
 
　　面對種種不利天氣，農(nóng)民們可真的是要“龍口奪糧”了。當(dāng)?shù)剞r(nóng)機(jī)部門應(yīng)積極引進(jìn)履帶式小麥聯(lián)合收割機(jī)作業(yè)，同時(shí)，加強(qiáng)本地聯(lián)合收割機(jī)技術(shù)指導(dǎo)，時(shí)間將操作技術(shù)要點(diǎn)發(fā)送到機(jī)手手中，確保夏收可以順利進(jìn)行。
 
　　目前，西南地區(qū)冬小麥和油菜、長江中下游地區(qū)油菜收獲均接近尾聲，湖北冬小麥?zhǔn)斋@過半。預(yù)計(jì)未來十天(5月29日至6月7日)，江蘇、安徽、河南、山東、湖北等地冬小麥將進(jìn)入大面積集中收獲階段，上述地區(qū)多晴好天氣，氣象條件總體利于夏收作物收曬，應(yīng)抓住有利時(shí)機(jī)，及時(shí)收割成熟小麥，已收獲地區(qū)要注意晾曬和通風(fēng)儲存，防止發(fā)芽霉變。
