摘　　要：针对辽宁稻区缺水和水资源浪费现象,进行了本项研究,结果表明无水层栽培可以降低水稻的无效分蘖、穗粒数,提高有效穗数、千粒重。无水层栽培全生育期可节水35%以上,有利于缓解北方稻区用水紧张问题,是一项值得推广的水稻节水新技术。This disquisition is aim at the short of water and the waste of water.The result indicate that planting of none-water layer can reduce the rice`s invalid tillering,grain of fringe,increase the effective fringe,the weight of kilo-grain.During the whole generational period it can save the water over35%,it is propitious to settle the water intense question and is good for extendability.
