摘要
作者在肥床的基础上进行水稻塑料软盘旱育苗抛秧试验，发现该方法可育成杂交稻大苗进行抛秧。所育苗有秧龄长、秧苗大、抗逆性强、立苗快等特点，抛秧工效则比其它形式大苗提高３～７倍，产量增１０％左右。该技术集旱育秧与软盘育苗抛秧优点于一身，并弥补了各自的不足，非常适于在晚茬、薄地和秧龄较长以及对杂交水稻生育期要求严格的地区应用。
In the seedling-throwing culture,there are mainly three methods of seedling-raising,i.e.,seedling-raising in plastic plates(only small or younger seedlings can be raised ),seedling-raising bychemical control(big or older seedlings raised, but too technical for farmers to master easily) and seedling-raising on dryland ferfilized beds (big seedlings raised but a late seedling upstanding).The new method ofraising seedlings in plastic plates on dryland fertil ized beds,combining the advantages of the abOve methods,can not only raise big seedlings with a longer seedling age for the throwing cuIture,but also raise seedlingsof strong stress resistance and earlier seedling upstanding.Futhermore,its work efficiency of seedling-throwing was 3～7 times as much as that of the other big-seedling-raising methods and its yield was high-er(by 4.4%～12.7%).This method is especially suitable for those areas in which a narrow range of growthperiod is required for hybrid rice,and for the later cropping season needing a longer seedling age.
