摘　　要：在大型的蒸渗仪中,研究了不同水肥处理对水稻产量及其构成因素的影响。结果表明,与传统的淹灌相比,节水灌溉在一定程度上控制了株高的生长,抑制了分蘖特别是无效分蘖的发生,同样可以获得高产,提出了一种高效利用水肥的稻田管理方式。An experiment was carried out in the lysimeter in order to investigate the effects of different water and nitrogen supply on yield and its components. Results showed that water saving irrigation can partly reduce the height of rice and re- strain invalid tillers. And it can obtain high yield with the flood irrigation equally, an optimum management pattern for high yield, water saving, and high nitrogen was also presented.
