旱育秧(dry rice-nursery) 旱育秧(dry rice-nursery) 整个育秧过程中，只保持秧田土壤湿润而不建立灌水层的育秧方法。其优点是：①土壤氧气充足，有利于萌芽中子进行旺盛的有氧呼吸，促进种子贮藏物质的转化，秧苗粗壮；②旱秧体内含碳、氮量高，移栽后发根力强，返青分蘖快；③旱秧细胞组织致密，自由水含量少，束缚水含量较高，植株挺韧，较耐低温、干旱，抗逆性强；④旱身比水身能早成熟，有利于抗低温增产。但抗苗稻温的能力较弱。旱育秧具有适应北方无霜期短、气温低、水源不足等生态特点的能力。20世纪70年代首先在东北各省推广应用，现已成为中国北方稻区培育壮秧、节水抗旱的一种重要育秧方法。 秧田选地和床土培养：选择土质肥沃疏松、保水保肥力强、排水良好、pH较低、水源方便的旱地、园田或水田做固定秧田。经年年多施农家肥，培养出理想的旱秧田。 整地做床：清除根茬施优质农肥后，浅翻或旋耕10cm深。秧床规格同保温湿润育秧。做床后施氮、磷化肥，碎土整平，床面再用木磙镇压好。也可采取铺营养土方法，即在浅翻整平压平床面后，先均匀撒施化肥，再将配制好的营养土层呈湿润壮态。床土用草炭、腐殖酸或硫酸等酸化材料调整土壤pH值，有较好的防止黄枯、立枯和培育壮秧作用。 播种：播种期可比一般薄膜育秧早3-4天，播种量要稀一些。北方一般每平方米150-200g。播后压种入泥一半，使种子与潮土紧密结合，然后覆盖细肥土1cm左右，并喷除草剂。再搭架盖膜。 秧田管理：播后至一叶一心前密闭保温，以后温度控制指标参照薄膜湿润育身。一叶一心期必须及时喷杀菌剂“敌克松”预防立枯病。当土壤干燥、傍晚秧苗叶片不能展开时即应浇透水，可采取喷灌办法以节省劳动力。盐碱地区旱育秧，为预防盐害，也可采取床面过水，即灌水2-3小时后排除，追肥方法，用硫酸铵兑水100倍喷浇，浇完再用清水冲洗一遍，以防伤叶。
