可能花苞太多了,养分供应不足,可以给它追加点肥料,摘掉一些小花苞,每枝只留顶端一个花苞。另外康乃馨喜充足的光照(每天至少需要4、5个小时)每天只需浇一次水。   盆栽种植   康乃馨喜空气干燥、通风良好、日照充足的环境,忌高温多湿,最适生长气温为19~21℃。栽培土壤要求保肥、通气、排水良好,富含腐殖质。   盆栽康乃馨,应选内径较大的高筒盆,盆底先施足含钾、钙、氮、磷的基肥。移植后,晴天每天浇水一次,保持盆土潮润。因为康乃馨既怕水涝,也不耐干旱。   生长期间每隔半个月交替施1次稀尿素水、麦秸杆烧的灰或酱渣肥料。值得注意的是:康乃馨不宜施浓肥。   每天保证光照6~8小时。盛夏时,康乃馨正处于半休眠状态,这时应注意避免烈日曝晒。盆土忌积水,否则易烂根。为促其分枝,在株高15~20厘米时去顶。   一般保留下部侧芽6~7个,以后再进行一次摘心,最后使植株有12~14个侧枝。孕蕾时每枝只留顶端一个蕾,要把下部腋生侧蕾和侧芽全部摘去。第二次摘去必须在8月中旬以前进行。
