Study on Growth Responses of Lycoris haywardii to Watering Frequencies
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.
