本網訊 8月下旬(xun)以來(lai)，西北(bei)(bei)東部、黃淮、江漢、華北(bei)(bei)和東北(bei)(bei)地(di)區(qu)先后出(chu)現大范(fan)圍降雨天氣(qi)過程，累(lei)計降雨量普(pu)遍在(zai)25-50毫米，土(tu)壤墑情得到改善(shan)，大部受旱地(di)區(qu)旱情得以緩解。

　　據各地反映和專家分析，旱情緩解對當前秋糧生產和即將開始的秋冬種極為有利。一是促進玉米灌漿(jiang)。8月下(xia)旬至9月上(shang)旬，正值黃淮、西北(bei)、華北(bei)和東(dong)北(bei)地區玉米(mi)灌漿(jiang)成(cheng)熟期，正是(shi)需水(shui)高峰期。大(da)(da)范圍降雨，旱情緩(huan)解，對(dui)于增加灌漿(jiang)速率和強度，提(ti)高粒重(zhong)較(jiao)為(wei)有(you)利(li)。二(er)是(shi)利(li)于抵(di)御早霜危害。土壤濕度大(da)(da)可以(yi)抵(di)御低溫空氣下(xia)沉，對(dui)防御霜凍作(zuo)用明顯。三是(shi)利(li)于增墑(di)保(bao)秋播。降雨有(you)效(xiao)改(gai)善了陜中南(nan)(nan)部(bu)、山西南(nan)(nan)部(bu)、河(he)南(nan)(nan)大(da)(da)部(bu)、安(an)徽北(bei)部(bu)和江蘇(su)中北(bei)部(bu)土壤墑(di)情，降水(shui)滲透一般達30-40厘米(mi)。河(he)南(nan)(nan)農業(ye)大(da)(da)學(xue)郭(guo)天財教授(shou)講，麥(mai)收隔年墑(di)，當前冬麥(mai)區底墑(di)充足，既利(li)于適墑(di)播種，又利(li)于安(an)全越冬。

　　針對前(qian)期(qi)(qi)東北、黃淮等(deng)地(di)(di)較(jiao)為嚴(yan)重的旱情，各(ge)級農業部(bu)門加(jia)強指(zhi)(zhi)導(dao)服務(wu)(wu)，落(luo)實關鍵(jian)技(ji)(ji)術，加(jia)大資金支持(chi)力度，推(tui)進(jin)(jin)科學(xue)抗旱，努力減輕(qing)災害(hai)損失。目前(qian)，距秋(qiu)(qiu)(qiu)(qiu)糧(liang)(liang)(liang)大面積(ji)收(shou)獲還有20天(tian)左右的時(shi)間，受厄爾尼諾(nuo)現象影(ying)響，后(hou)期(qi)(qi)秋(qiu)(qiu)(qiu)(qiu)糧(liang)(liang)(liang)和(he)秋(qiu)(qiu)(qiu)(qiu)冬(dong)(dong)種(zhong)(zhong)(zhong)(zhong)生(sheng)產仍面臨早(zao)(zao)霜、寒露風和(he)干旱等(deng)多重威(wei)脅。農業部(bu)將(jiang)立(li)足抗災奪豐收(shou)，全面推(tui)動各(ge)項措施落(luo)實，確(que)保秋(qiu)(qiu)(qiu)(qiu)糧(liang)(liang)(liang)顆(ke)粒歸倉和(he)秋(qiu)(qiu)(qiu)(qiu)冬(dong)(dong)種(zhong)(zhong)(zhong)(zhong)工作順利展(zhan)開。一是(shi)密(mi)切(qie)關注重大天(tian)氣變化。加(jia)強與氣象、水利等(deng)部(bu)門的溝通協作，密(mi)切(qie)關注重大天(tian)氣變化，及(ji)時(shi)發布預(yu)警(jing)信息。二(er)是(shi)繼續抓(zhua)好秋(qiu)(qiu)(qiu)(qiu)糧(liang)(liang)(liang)后(hou)期(qi)(qi)管理。指(zhi)(zhi)導(dao)各(ge)地(di)(di)搞(gao)好秋(qiu)(qiu)(qiu)(qiu)糧(liang)(liang)(liang)后(hou)期(qi)(qi)肥(fei)水調控，促進(jin)(jin)安全成(cheng)熟(shu)(shu)。指(zhi)(zhi)導(dao)各(ge)地(di)(di)區抓(zhua)緊檢修農機具(ju)，集中人力物力，加(jia)快收(shou)獲進(jin)(jin)度，做(zuo)到成(cheng)熟(shu)(shu)一塊收(shou)獲一塊，確(que)保秋(qiu)(qiu)(qiu)(qiu)糧(liang)(liang)(liang)顆(ke)粒歸倉。三(san)是(shi)及(ji)早(zao)(zao)安排秋(qiu)(qiu)(qiu)(qiu)冬(dong)(dong)種(zhong)(zhong)(zhong)(zhong)生(sheng)產。指(zhi)(zhi)導(dao)各(ge)地(di)(di)提(ti)前(qian)做(zuo)好秋(qiu)(qiu)(qiu)(qiu)冬(dong)(dong)種(zhong)(zhong)(zhong)(zhong)各(ge)項準備(bei)，調劑調運適(shi)宜品種(zhong)(zhong)(zhong)(zhong)，搶墑(di)搶時(shi)播(bo)種(zhong)(zhong)(zhong)(zhong)，確(que)保秋(qiu)(qiu)(qiu)(qiu)冬(dong)(dong)種(zhong)(zhong)(zhong)(zhong)面積(ji)落(luo)實。四是(shi)加(jia)強指(zhi)(zhi)導(dao)服務(wu)(wu)。組(zu)織專家提(ti)前(qian)制(zhi)定秋(qiu)(qiu)(qiu)(qiu)冬(dong)(dong)種(zhong)(zhong)(zhong)(zhong)技(ji)(ji)術方案，開展(zhan)巡(xun)回指(zhi)(zhi)導(dao)和(he)技(ji)(ji)術培訓，幫助農民落(luo)實科學(xue)抗災和(he)秋(qiu)(qiu)(qiu)(qiu)冬(dong)(dong)種(zhong)(zhong)(zhong)(zhong)技(ji)(ji)術措施。
