当你发现栽种的仙人掌色泽不对劲,逐渐干瘪,枝干或掌片耷拉下垂时,就表明仙人掌的生长出了问题。要挽救仙人掌,首先要找到问题所在,对症下药并及时救治。其次,为仙人掌提供更为适宜的土壤、光照条件和生存环境,让它能够长期茁壮成长。
步骤
- 为越长越瘦的仙人掌提供更多的光照。如果球状仙人掌顶端越长越尖,或者柱状仙人掌越长越细,就表示仙人掌黄化了。造成黄化的原因是光照不足。你需要把仙人掌移到阳光照射时间较长的地方,比如朝南的窗户;或者阳光照射强度较大的地方,比如朝西的窗户。[5]
- 找到仙人掌发黄的区域。如果仙人掌朝向太阳的部分发黄,甚至变成了褐色,就说明仙人掌暴晒过度,被灼伤了。你需要立刻把它移到阴凉的地方,比如朝东的窗户,那里的阳光比较柔和。[6]
- 留心观察一下,仙人掌对阴凉的新环境反应如何。如果过了几周,发黄的区域还是没有改善,就把它切除,一直切到健康的绿色区域为止。
- 消灭害虫。危害仙人掌的害虫主要是粉虱和红蜘蛛。粉虱个头很小,呈粉白色,总是成群结队出没。红蜘蛛是一类红色的螨虫,个头也很小,常常在仙人掌的刺之间结出一片片的网。要消灭这两种害虫,你可以用棉签蘸点酒精,涂抹在虫害区域。[7] 此外,杀螨药也可以用来消灭红蜘蛛。[8]广告
- 等土壤干透了才浇水。你可以把手指插入土壤里大概3厘米深的地方,感受一下土壤湿不湿。如果感觉干透了,就可以浇水了,浇水时需要浇到土壤彻底湿透,多余的水从花盆底部流出来为止。 [12]
- 为仙人掌提供充足的光照。仙人掌的生长大多需要充足的阳光。在夏天,你可以把仙人掌移到户外,只要不让它淋到太多的雨就行。但是不能够一下子把仙人掌移到阳光最猛烈的地方,因为它会被晒伤。你可以把仙人掌逐步移到阳光越来越强烈的地方,让它有一个逐渐适应光照强度的过程。[15] 到了冬天,则需要把仙人掌移到在朝南或朝西的窗户上,那里的阳光正好。
- 洗掉仙人掌表皮上的污渍。如果仙人掌的表皮上都是污渍,就会妨碍它正常地进行光合作用。[29] 可以用抹布或海绵蘸一点洗洁精,洗掉这些污渍,然后用吸饱水的海绵将仙人掌擦洗干净,或者把仙人掌放在水龙头下用水冲洗干净。广告
