[目的]探明节水稻新品种＂绿旱1号＂的水分利用率,为其进一步示范推广提供参考依据。[方法]对节水稻新品种＂绿旱1号＂与原始受体6527进行全生育期无水层旱处理,以正常灌溉为对照。[结果]在较正常灌溉节水67.4%的条件下,＂绿旱1号＂千粒重、结实率、株高、有效穗降幅较小,且均未达显著水平,而原受体＂6527＂小区产量、穗总粒数、理论产量、穗实粒数降幅均超过25%,且均达极显著水平（P〈0.01）。[结论]＂绿旱1号＂在节水栽培条件下,表现出产量稳定、节约能源、减少环境污染等优点。

[Objective] This study aimed at exploring the utilization rate of water of the new water-saving rice variety ＂Luhan No.1＂ and providing references and basis for the further demonstration and extension.[Method] Water-saving rice variety ＂Luhan No.1＂ and original receptor ＂6527＂ were used for dry processing without aquifer,and rice under regular irrigation conditions was used as the control.[Result] Under conditions which had economized on 67.4% of water compared with the regular irrigation,decreasing rates of 1 000-seed weight,seed setting rate,plant height and effective panicles of ＂Luhan No.1＂ were relatively small and had not achieved a significant level,while the decreasing rates of production of the region,total grains per panicle,theoretical production and filled grains per panicle of the original receptor ＂6527＂ were all over 25% and had attained very significant levels（P0.01）.[Conclusion] ＂Luhan No.1＂ had shown stable production,energy conservation,reducing environmental pollution and other advantages under water-conservating cultivation conditions.
