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。
The effects of water stress on the number of flowering branches, length of flowering branch, flowering stage and leaf disease were studied with orchid “Xiaguang” as test material. The results showed that watering once every 10 days was beneficial to the increase of flowering number and flowering period (the number of flowering days was up to 52 days) compared with the control treatment (watering once every 5 days), which was good for plant disease control happened. Indicating that proper water control irrigation is conducive to improve the flowering of orchids.
