盆栽枯萎怎么办?盆栽常见症状及解决方案

盆栽枯萎

盆栽花卉在生长期间,时会出现叶片变黄。产生叶片变黄的原因有很多,有的是一种原因引起的,有的是多种原因引起的。在养护过程中,必须细心观察,分析其原因才能有针对性地加以防治。

一、浇水过度

发黄原因:盆土积水久湿,造成土壤缺氧,使部分根系腐烂、吸水、吸肥能力减弱。

表现:嫩叶暗黄无光泽,新梢顶心萎缩,枝茎细小黄绿。

解决方法:发生此种情况应进行松土,控制浇水,停止施肥,重者可脱盆,置阴处吹干土球后再上盆。

二、浇水太少

发黄原因:由于长期没浇水,或浇水偏少。

表现:叶片发黄或棕端、棕边,老叶自下而上的枯黄脱落,但新叶一般生长正常。

解决方法:此种现象发生时应补充水分,使土壤不再缺乏水分。

三、施肥过度

发黄原因:由于施肥过多或浓度过大,尤其是偏施氮肥而引起的叶黄。

表现:新叶肥厚而富有光泽,但叶面凹凸不舒展,老叶逐渐变黄而脱落。

解决方法:此时应停止施肥并适当增加浇水量以冲淡养分,盆花肥水不足或棵大盆小,盆内根系衰老或过密,也会使花卉植株的叶片变薄,变黄,此时应换盆换土。

四、施肥不足

发黄原因:盆花长期只浇水不浇肥,或多年不换盆。

表现:根须结成一团,植株得不到肥分,使叶发黄。

解决方法:除及时换盆外,平时应薄肥勤施。

五、光照过度

发黄原因:喜阴湿的盆花和观叶植物,如吊兰、万年青、一叶兰、玉簪以及竹芋等,被强烈阳光直射。

表现:叶片有卷边的现象。

解决方法:此种现象发生,将盆置阴处即可。
