摘　　要：以兰花"霞光"植株为试材,研究水分胁迫对植株的花枝数、花枝长度、花期和叶片病害的影响。结果表明:与对照处理(每隔5d浇水1次)相比,每隔10d浇水1次有利于促进植株花枝数的增加和花期的延长(花期天数可达52d),有利于控制植株病害的发生。说明适当的控水灌溉有利于提高兰花植株的开花品质。Taking ‘Xiaguang＇as material,the effect of water stress on the number and length of flower spikes,blooming days and diseases of‘Xiaguang＇were studied at the early blossom stage.The results showed that compared with control（water once every 5days）the plant of watering once every 10 days promoted the number of flower spikes,extended the blooming days（up to 52days）,and was helpful to control the occurrence of plant diseases in comparison with the control treatment（watering once every 5days）.It illustrated the proper water control irrigation was beneficial to improve the quality of flowering.
