网纹草怎么养,网纹草的养殖方法
网纹草怎么养,网纹草原产于热带非洲丛林中,性喜阴凉、高温与湿润环境,在高温高湿阴暗的环境中长得十分繁茂,华南地区在遮阴的温室中或有空调的房间中终年可栽培。网纹草的栽培温度一般应在18℃以上,低于这一温度会引起叶片脱落。
它生长的最适温度为20~30℃。网纹草在散射阳光下生长较好,当光线太强时,植株长得缓慢且矮小,叶片蜷缩并失去原来的色彩,影响其观赏价值。当室温低于18℃而不小于12℃时,网纹草植株叶片会脱落,但茎干不会冻死;第二年室温超过18℃时又会长出新叶,无叶的茎干也可用于剪切后扦插繁殖;在低于8℃的环境中,植株会冻死。
网纹草在生长季节需要较高的空气湿度,特别是夏季更应注意多浇水保持湿润,但浇水时叶片不能滞水,滞水过多过久会引起叶片腐烂和脱落,或引起茎腐病而导致植株死亡。因而网纹草盆栽时浇水一般将花盆放入水中短时浸泡让其充分吸水而减少浇水的次数,一般2~3天后盆土还能保持湿润。或在花盆盆底垫一小浅盘,浇水时既能防止水土流出弄脏环境,又能保持较高的空气湿度使植株生长茂盛。
网纹草的栽培基质以疏松、透气和肥沃者较好,当基质透水性差、积水过多时会引起烂根,导致植株生长不良甚至死亡。网纹草的栽培基质一般采用园土1份、泥炭土1份、河沙土和少量基肥混合而成,也可用椰壳和珍珠岩混合进行无土栽培,无土栽培时应勤施根部肥和喷洒叶面肥,使用的肥料一般采用复合肥即可。通常情况下在生长季节每周施肥1次。施肥时应特别注意不要将叶面肥过多地粘在叶面上,否则会引起叶面腐烂,影响其生长和观赏价值。
另外,为了保证网纹草的株形优美,新栽的盆苗应多次摘心,使植株的分枝多叶面茂,还应对植株下部脱叶或烂叶的茎干进行修剪,使植株株形美观并减少病虫害,以上就是关于网纹草怎么养的介绍。
