“早稻”又称“陆稻”,是栽培稻中一种特殊的生态类型,一生勿须水层,全靠自然降雨或在干旱发生到一定程度时辅以适量灌溉的稻作。尤其在目前水资源危机、种植结构、膳食结构调整中,早稻作为一种增收增效新兴粮作,显示出较大的优越性。黄淮冬麦区及我省中南部,均采用小麦-玉米等其它夏播作物两熟制,该生态区6～9月份期间,雨热同期,具有发展夏直播早稻的潜力。目前,夏直播早稻发展较快。但播种方法不一,一般沿 “Early rice”, also known as “Upland Rice”, is a special ecological type in cultivated rice. It does not require a water layer throughout its life. It relies solely on natural rainfall or supplemented with appropriate irrigation when the drought occurs to a certain extent. Particularly in the current crisis of water resources, planting structure and adjustment of dietary structure, early rice has shown greater superiority as a new crop with increased income and increased efficiency. Huanghuai winter wheat district and central and southern parts of our province are used two other summer sowing crops such as wheat and corn. During the period from June to September in this ecological zone, rain and heat have the same potential for the development of summer direct seeding early rice. At present, summer broadcast early rice developed rapidly. However, sowing methods vary, generally along
