摘　　要：[目的]探求红蓝石蒜最适宜的补水频率。[方法]以温室栽培的红蓝石蒜(Lycoris haywardii)为试验材料,采用主观判断补水(A0)、每周补水1次(A1)、每月补水2次(A2)、每月补水1次(A3)4种补水方式,研究水分对红蓝石蒜生长和鳞茎生物量的影响。[结果]A1处理叶数和鳞茎鲜重分别增加了111%、496%,其中鳞茎鲜重显著大于A3和A0,但与A2无显著性差异,一定程度上表现出补水间隔越短,叶数、鳞茎生物量增加越大。鳞茎数量在处理间无显著性差异。鳞茎生物量的差异可以在叶数或叶长方面表现出来。[结论]水分管理极其重要。每周浇水1次为最佳补水频率,并可根据天气条件适当调整。Objective] The aim was to seek the optimum of re-watering frequency for the bulb growth of Lycoris haywardii. [Method] A pot experiment with four treatments was conducted again to evaluate the effects of watering frequency on growth and bulb biomass of L. haywardii under greenhouse condition. [Result] The leaf number and fresh bulb weight was increased by 111% and 496% respectively, under the irrigation frequency of once a week, which was significantly greater than that of once a month and re-watering by subjective judgment, but there was no significant difference with that of once half a month. It was demonstrated the trend that the shorter watering interval, the greater the leaves and bulb biomass in certain degree. However, no significant differences were observed with regard to bulb number in all the treatments. The difference of bulb biomass may be displayed by leaf number or leaf length. [Conclusion] Watering management was very important for increasing bulb yield of Lycoris. The optimal watering frequency was once a week, and should be adjusted according to the weather conditions.
