Abstract: 黑龙江二道河农场处在三积温带下限,年积温2300℃,常年多雨、低温,土壤冷凉,易造成水稻不能安全成熟。结合几年来种植水稻的经验,现将我场常年促早熟的作法总结如下:1培育壮秧,提早插植1.1选用熟期在130天之内的抗病、抗逆性强的优良品种。如:合江19、绥92─188、垦鉴90─31等。1.2育苗阶段双调酸,可以抑制土壤中病原菌繁殖,又可保障水稻秧苗在酸性土壤中生长。双消毒可以大大减轻水稻恶苗病、立枯病发生。玉.3大、中拥有苗可提高棚温,从而保证育出壮秧和水稻正常成熟。2井水增温,节水泊研本场所有水稻都采用井灌,因此井水增温是保证水稻早熟高产的制约因素之一。通常采用长渠道增温、浅水灌溉以外,又增
