不同肥水EC值对观赏竹芋生长发育的影响

Effects of Different EC of Water-soluble Fertilizers on the Growth and Development of Maranta arundinacea under Greenhouse Cultivation

为了探索不同肥水EC值对竹芋生长的影响,将浓缩营养液配制成不同EC值的肥水,对比分析筛选出最适飞羽竹芋和“米娅”彩虹肖竹芋生长发育的浓度。结果表明,在EC值为1.2 mS/cm时,飞羽竹芋的株高、冠幅、叶片数、叶绿素含量等指标较优于其他处理,适合飞羽竹芋生长;而“米娅”彩虹肖竹芋在EC值为1.6 mS/cm时,生长最佳,各项指标较优于其他处理;此外,飞羽竹芋对肥水EC值较“米娅”彩虹肖竹芋敏感。

In order to explore the effect of EC value of water-soluble fertilizers on the growth of Maranta arundinacea,the concentrated nutrient solution was prepared with different EC value of water-soluble fertilizers,the optimal concentration of water-soluble fertilizers for the growth and development of Stromanthe sanguinea Sond.and Calathea roseopicta‘Mia’was selected by comparative analysis under greenhouse cultivation.The results showed that the best effect on promoting Stromanthe sanguinea Sond.growth was the EC value of 1.2 mS/cm with plant height,crown,leaf number and chlorophyll content;while under the EC value of 1.6 mS/cm,the growth of Calathea roseopicta‘Mia’was the best,which was better than other treatments;in addition,Stromanthe sanguinea Sond.was particularly sensitive to fertilizer concentration than Calathea roseopicta‘Mia’.
