观赏凤梨浇水方法
观赏凤梨浇水方法,观赏凤梨喜光和喜温热的环境,叶片带状、革质、基生,通常排列成莲座状;花茎一般较长,从中央抽出,顶部是一枝穗状花序。大多数品种叶片的基部相互重叠,形成一个不透水的组织,承担“贮水器”或“水槽”的作用。
“水槽”不但可以贮水防旱,而且还由于经常掉入的落叶、昆虫或动物排泄物等溶水成肥,再由“水槽”基部的鳞状毛吸收。凤梨科植物叶表面有一种称作“吸收鳞片”的组织(以叶片基部蓄积水分的部分最多),这种组织能吸收水分和养分。
所以,在栽培管理上,要注意在“水槽”内蓄足水分并对叶面进行施肥。施肥应以氮、钾肥为主,选择含磷量少的肥料,如2%o的尿素或硝酸钾等。凤梨科植物在开花期前后,会从植株基部叶间发出子株2~3株,可以此来繁殖。
