通常莲花竹杆发黄怎么办才好,若是根系腐烂就要及时更换水分,上盆后加入木炭防腐,土质不当则选用疏松性强的沙质土壤,光照过强就要将花盆放在光照柔和的环境中,空气湿度太干应每天喷雾1~2次,保持盆土湿润即可。

1、换水处理

莲花竹用于水培是常见的养殖方式,如果由于水里的病菌导致根系腐烂,植株的竹杆和茎叶就会出现发黄干枯的现象,此时应及时的更换水质,换水前将腐朽的根须剪除,用消毒液消毒后再重新上盆,向基质里加入适量木炭即可。

2、更换土壤

莲花竹采用土培也是常用的栽培方法,如果选用的土壤通透性比较差的话,长时间会导致烂根,植株就会出现发黄枯萎的现象,那么莲花竹杆发黄怎么办,此时应更换疏松性强的肥沃沙质土壤,在上盆前在底层加入适量的碎瓦片或者粗沙即可。

3、减少光照

虽然莲花竹是一种喜阳植物,在充足的阳光下能生长繁茂,但如果光照过强或者长久置于强光环境下,会直接导致植株的发黄枯萎,在平时的时候放在阳光充足的环境中,强光季节要将花盆放在光照柔和的位置处,或者遮阴处理即可。

4、增加湿度

莲花竹在湿润的环境中生长比较合适,如果水分过少或者盆土干燥的话,会抑制植株的生长从而出现竹杆发黄死亡的现象,在平时中要给予充足的水分,如果空气过于干燥或者处于高温天气,最好每天喷雾1~2次,保持盆土湿润即可。

5、减少施肥

栽培莲花竹的时候,施肥最好要适量进行,如果肥料过多或者过少的条件下,都会引起植株竹杆出现发黄的现象,叶片颜色会慢慢变淡,若是水培的话施肥最好要将之前的水换掉,待一周后施加培养液即可,若是土培的话,生长期间每月施一次稀薄的液肥溶液。

6、病虫预防

栽培莲花竹的生长环境很容易引发病虫的危害,主要有叶斑病和根腐病的危害,开始由褐色不规则的斑点慢慢扩散成不规则深褐色斑块,而且会导致植株发黄枯萎,此时将要害部位剪去,用波尔多液喷洒多次即可。
