  大发(fa)体育客户端(duan)8月25日电 据(ju)国(guo)家统(tong)计(ji)局消息,2021年,全(quan)国(guo)早(zao)稻(dao)(dao)播种面(mian)积稳中略降,单(dan)产(chan)恢复性增(zeng)(zeng)长(zhang),早(zao)稻(dao)(dao)产(chan)量较上年小幅增(zeng)(zeng)长(zhang)。根据(ju)10省(区)早(zao)稻(dao)(dao)实(shi)(shi)割(ge)实(shi)(shi)测抽样调查结果推算(suan),全(quan)国(guo)早(zao)稻(dao)(dao)总产(chan)量2802万吨(560亿(yi)斤),比(bi)2020年增(zeng)(zeng)加(jia)72.3万吨(14.5亿(yi)斤),增(zeng)(zeng)长(zhang)2.7%。

  一、早稻播种面积稳中略降。

  2021年全国早(zao)稻播种(zhong)面积(ji)(ji)4734千公顷(qing)(qing)(qing)(7101万亩),比上年减少16.6千公顷(qing)(qing)(qing)(24.9万亩),下(xia)(xia)降0.4%。其中,广(guang)西、江西播种(zhong)面积(ji)(ji)分别增加2.3千公顷(qing)(qing)(qing)(3.5万亩)和1.3千公顷(qing)(qing)(qing)(1.9万亩),增长0.3%和0.1%;广(guang)东、湖(hu)南受(shou)干(gan)旱以及种(zhong)植结构(gou)调整影响,播种(zhong)面积(ji)(ji)分别减少10.6千公顷(qing)(qing)(qing)(15.9万亩)和6.1千公顷(qing)(qing)(qing)(9.2万亩),下(xia)(xia)降1.2%和0.5%。

  早(zao)稻(dao)(dao)播(bo)(bo)种(zhong)(zhong)(zhong)面(mian)(mian)积(ji)有所下(xia)降(jiang)主要(yao)是(shi)以(yi)下(xia)两(liang)方面(mian)(mian)因素(su)造成的。一是(shi)天(tian)气干旱(han)影响早(zao)稻(dao)(dao)适时移栽。华南(nan)部(bu)分地(di)区(qu)春播(bo)(bo)气象(xiang)条件较差,降(jiang)水量较常年同期偏少,广东、广西(xi)中南(nan)部(bu)等(deng)地(di)蓄水不足,部(bu)分地(di)块灌溉条件较差,影响早(zao)稻(dao)(dao)适时移栽,农(nong)户改种(zhong)(zhong)(zhong)玉(yu)米(mi)、甘薯等(deng)作物。二是(shi)种(zhong)(zhong)(zhong)植结(jie)构(gou)(gou)调(diao)整(zheng)减少早(zao)稻(dao)(dao)种(zhong)(zhong)(zhong)植。湖南(nan)受污染(ran)耕(geng)地(di)严格管控区(qu)种(zhong)(zhong)(zhong)植结(jie)构(gou)(gou)调(diao)整(zheng),退出水稻(dao)(dao)种(zhong)(zhong)(zhong)植,导致(zhi)播(bo)(bo)种(zhong)(zhong)(zhong)面(mian)(mian)积(ji)下(xia)降(jiang)。但各地(di)多措并举稳定(ding)早(zao)稻(dao)(dao)生产,层(ceng)层(ceng)压实粮(liang)(liang)食(shi)生产责任,加(jia)大政(zheng)策扶(fu)持力度,开展撂荒地(di)复垦复种(zhong)(zhong)(zhong),鼓(gu)励(li)种(zhong)(zhong)(zhong)粮(liang)(liang)大户、专(zhuan)业(ye)合(he)作社、农(nong)业(ye)企业(ye)种(zhong)(zhong)(zhong)植早(zao)稻(dao)(dao),落实各项支(zhi)农(nong)惠农(nong)、种(zhong)(zhong)(zhong)粮(liang)(liang)补贴、粮(liang)(liang)食(shi)最低收购价等(deng)政(zheng)策,早(zao)稻(dao)(dao)播(bo)(bo)种(zhong)(zhong)(zhong)面(mian)(mian)积(ji)保持了基本稳定(ding)。

  二、早稻单产水平有所增加。

  2021年(nian)全(quan)国早(zao)稻(dao)单产5918公(gong)斤(jin)(jin)/公(gong)顷(qing)(qing)(395公(gong)斤(jin)(jin)/亩(mu)),比上年(nian)增加173.0公(gong)斤(jin)(jin)/公(gong)顷(qing)(qing)(11.5公(gong)斤(jin)(jin)/亩(mu)),增长3.0%。其(qi)中,安徽、湖北、江西(xi)上年(nian)因(yin)受严重洪(hong)涝灾害影(ying)响单产明显(xian)下降,今(jin)年(nian)呈(cheng)现恢(hui)复性(xing)增长,分别增加449.3公(gong)斤(jin)(jin)/公(gong)顷(qing)(qing)(30.0公(gong)斤(jin)(jin)/亩(mu))、359.3公(gong)斤(jin)(jin)/公(gong)顷(qing)(qing)(24.0公(gong)斤(jin)(jin)/亩(mu))和210.3公(gong)斤(jin)(jin)/公(gong)顷(qing)(qing)(14.0公(gong)斤(jin)(jin)/亩(mu)),增长8.4%、6.4%和4.0%。

  早(zao)稻(dao)播种以来,主产(chan)区(qu)(qu)(qu)大部(bu)时(shi)(shi)段气象条件(jian)较(jiao)好,阶段性阴雨寡照和(he)(he)洪(hong)涝灾害发生偏(pian)轻,总体有利于早(zao)稻(dao)生长发育和(he)(he)产(chan)量形(xing)成。播种育秧至移栽返青期(qi),早(zao)稻(dao)产(chan)区(qu)(qu)(qu)气温(wen)偏(pian)高(gao),光照充足,降(jiang)水(shui)(shui)及(ji)时(shi)(shi),秧苗整齐健壮。分(fen)蘖拔节至孕穗抽(chou)穗期(qi),江南、华南北部(bu)地(di)区(qu)(qu)(qu)出现多次区(qu)(qu)(qu)域性较(jiao)强降(jiang)水(shui)(shui)过程,但(dan)后期(qi)天气明显(xian)好转,光温(wen)资(zi)源充沛(pei),利于抽(chou)穗结实和(he)(he)病虫害防治。灌(guan)浆收获期(qi)间,早(zao)稻(dao)产(chan)区(qu)(qu)(qu)以晴(qing)热少雨天气为主,高(gao)温(wen)日数较(jiao)常年同(tong)期(qi)偏(pian)多,有利于早(zao)稻(dao)灌(guan)浆和(he)(he)成熟。同(tong)时(shi)(shi),尽管(guan)沿(yan)海(hai)部(bu)分(fen)地(di)区(qu)(qu)(qu)受台风影(ying)响(xiang),早(zao)稻(dao)出现倒(dao)伏(fu),但(dan)总体影(ying)响(xiang)有限。

  在全(quan)球疫情持(chi)续(xu)演变、外部环境复(fu)杂严(yan)峻的(de)背景下,夏(xia)粮丰收和早稻增产奠定(ding)了全(quan)年粮食稳定(ding)生产的(de)基础,为“十四五(wu)”开好局、起好步(bu)提(ti)供了坚(jian)强有力的(de)支撑(cheng)。(大发体育APP)
