不同浇水频率对鼠尾草生长的影响

The Effects of Different Watering Frequency on Growth of Salvia officinalis

[目的]探讨鼠尾草生长所需水分条件。[方法]共设3个浇水频率,即分别每隔5、8、11d对鼠尾草浇水1次。每处理50盆,3次重复。[结果]5d浇水1次的鼠尾草植株现蕾、开花时间均早于每隔8d的浇水处理,且花期持续时间较长。11d浇水1次的植株在现蕾期前干枯。5d浇水1次处理的植株高度、花序长度、花梗长度、植株各部位干重与鲜重均大于每隔8d的浇水处理,叶片数与叶长变化则与其相反。[结论]每隔5d浇水1次有利于鼠尾草的生长。

[Objective]The study aimed to explore the water condition of Salvia officinalis. [Method]3 watering frequencies was designed,i. e. every 5,8,11 days respectively for 1 time watering. Every treatment had 50 pots and 3 repeats. [Result]The time of flower bud and flowering of treatment of every 5 days for 1 time watering was earlier than that of every 5days for 1 time watering,and it continued for a longer duration. The plant height,length of inflorescence and pedicel and dry weight and fresh weight of treatment of every 5 days for 1 time watering was greater than that of treatment of every 8 days for 1 time watering,but leaf number and change of leaf length was opposite with treatment of every 5 days for 1 time watering. [Conclusion]The treatment of every 5 days for 1 time watering was good for growth of Salvia officinalis.
