農(nóng)業(yè)農(nóng)村部與中國氣象局聯(lián)合發(fā)布水稻高溫熱害預報預警

　　【農(nóng)機網(wǎng) 熱點關注】 8月初，南方多地高溫天氣“火力全開”。對此，農(nóng)業(yè)農(nóng)村部和中國氣象局聯(lián)合發(fā)布水稻高溫熱害預報預警信息，提供農(nóng)事建議。
 
　　據(jù)統(tǒng)計，8月3日，在四川、貴州、湖南等地，有14個國家氣象站的氣溫達到建站以來歷史最高，其中四川瀘縣41.9℃、貴州從江39.5℃、湖南通道38.1℃。從氣溫來看，多地已達35℃以上，但地表可感受到50℃乃至更高的溫度。當前江南、江漢等地一季稻正值孕穗抽穗期，西南地區(qū)正值抽穗揚花期、局地已經(jīng)灌漿，高溫天氣可能導致部分一季稻遭受輕至中度高溫熱害。此外，高溫天氣對晚稻秧苗生長和移栽返青、蔬菜、經(jīng)濟林果等生長發(fā)育也不利。
 
　　中央氣象臺預計，從當前至8月12日，江南西部、華南西部、江漢東部和南部等地還將有3至6日最高氣溫超過35℃以上的高溫天氣，部分地區(qū)最高氣溫達37℃至39℃。四川盆地高溫天氣還將維持兩日左右。
 
　　專家建議，四川、重慶、湖北、湖南、貴州、廣西等地可采用灌深水或噴施植物調(diào)節(jié)劑等措施，減輕高溫熱害對水稻等作物的影響。
 
　　此前，農(nóng)業(yè)農(nóng)村部、水利部、應急管理部、中國氣象局聯(lián)合召開全國農(nóng)業(yè)防災減災工作推進視頻會，進一步完善部門信息共享機制，加強溝通會商，做好災害監(jiān)測預警。
