摘　　要：水稻无水层灌溉栽培可以降低水稻的无效分蘖、株高、有效穗数,提高穗粒数、千粒重、结实率。水稻无水层灌溉栽培技术可节水21.6%,有利于缓解农业用水紧张问题,是一项值得推广的水稻节水技术。No-water layer irrigating rice cultivation was able to lower inefficient tillers, plant height and effective panicles, 1000-grain weight and seed set rate. This irrigating method could save water by 21.6%, which relieves water use shortage, and is worth extending.
