#牡丹栀子 为什么不开花?牡丹栀子不开花怎么办?很多花友常会碰到问题,家里养的牡丹栀子叶子很好,可是就是不开花,怎么回事呢?今天花匠大叔介绍牡丹栀子不开花的原因。



第一、水肥不当:水肥一旦过量,就会引起植株徒长,生殖生长没有足够的养分就会影响花芽形成,导致不开花或开花很少,有的开了,甚至会马上脱落。在花芽分化期要特别注意磷、钾肥的搭配,比如0.2%磷酸二氢钾溶液,有利于花芽的形成和孕蕾;孕蕾期施肥过浓,浇水忽多忽少,也会造成落花落苗。

第二、光照不适宜:栀子花喜阴,要特别注意夏季过强和冬季过弱的光照,光照过强过弱都会影响桅子花开花.

第三、土壤含碱高:栀子花喜欢酸性土壤,栽培桅子花土壤含盐含碱高,就会造成植株黄化,最终会影响开花。

第四、不修枝整形:桅子花枝条杂乱,大量的杂枝消耗大量的养料以及枝条过密,影响光合作用,都是造成不开花的重要原因。

第五、病虫害严重:这个相信大家都能理解,病虫害严重势必造成落花落蓄。
