桑叶牡丹的叶子出现发黄的现象,可能是生长过程中过量浇水所导致的,或者是使用的培养基质不适,碱性过大导致植物的叶子出现发黄现象,若是长时间的缺少光照或者是根部腐烂,也会导致桑叶牡丹的叶子发黄。

桑叶牡丹叶子发黄原因

1、过量浇水

若是在桑叶牡丹的生长过程中过量浇水,多余的水分无法吸收长时间的浸泡根部,便会导致桑叶牡丹的叶子出现发黄的现象,此时需要及时的将多余的水分排出,必要情况下需要脱盆放置阴凉处将水分蒸干之后进行栽种。

2、基质不适

桑叶牡丹叶子为什么发黄可能是基质不适所导致的,桑叶牡丹喜欢在酸性通气的土壤中生长,若是使用过碱的土壤进行栽种,便会导致桑叶牡丹的叶子发黄,若是土壤的板结情况十分的严重,会容易出现闷根的现象,所以此时需要更换酸性以及通气能力强的土壤进行种植。

3、缺少光照

桑叶牡丹在生长过程中是离不开光照的,若是长时间没有给予光照若是光照不足,会影响到叶子进行光合作用,所以也会导致桑叶牡丹的叶子逐渐发黄,此时需要及时的补充光照,将光照时间维持在6个小时以上。

4、根部腐烂

桑叶牡丹的叶子发黄也有可能是根部出现病害,进行脱盆处理之后检查根部是否有腐烂现象,用清水将根部进行清洗,之后可用高锰酸钾溶液浸泡根部杀掉根部的病毒,之中再选用酸性土壤继续种植即可。
