牡丹的春季管護直接影響到其開花質量和花後生長。在日常管理中若對牡丹的生態習性了解不夠很容易走進春季管護的誤區。

誤區一:澆水過晚

    春季氣溫回升快但極不穩定。早春澆水可以有效降低地溫延緩植株萌芽以免植株受到晚霜和倒春寒的危害。但澆水過晚不僅起不到防寒、防fang凍dong的de作zuo用yong還hai會hui影ying響xiang開kai花hua質zhi量liang。因yin此ci澆jiao水shui宜yi早zao不bu宜yi遲chi應ying澆jiao足zu澆jiao透tou以yi土tu表biao不bu積ji水shui為wei度du。另ling外wai需xu要yao一yi提ti的de是shi在zai牡mu丹dan的de盛sheng花hua期qi應ying控kong製zhi澆jiao水shui否fou則ze會hui縮suo短duan花hua期qi使shi花hua朵duo過guo早zao凋diao謝xie。

誤區二:修剪不當

誤區三:花後缺肥

牡丹通常一年施3次肥即秋後的基肥、早zao春chun的de花hua前qian肥fei和he仲zhong春chun的de花hua後hou肥fei。日ri常chang往wang往wang容rong易yi忽hu視shi春chun季ji的de花hua後hou肥fei實shi際ji上shang這zhe次ci施shi肥fei非fei常chang重zhong要yao直zhi接jie影ying響xiang到dao牡mu丹dan的de生sheng長chang和he花hua芽ya分fen化hua。雖sui然ran開kai花hua前qian施shi用yong了le肥fei料liao但dan經jing過guo開kai花hua養yang分fen已yi消xiao耗hao此ci時shi不bu追zhui肥fei會hui影ying響xiang植zhi株zhu以yi後hou生sheng長chang造zao成cheng長chang勢shi衰shuai退tui影ying響xiang花hua芽ya分fen化hua。在zai花hua謝xie後hou半ban個ge月yue內nei要yao追zhui施shi一yi次ci以yi磷lin肥fei為wei主zhu的de複fu合he肥fei同tong時shi也ye可ke適shi當dang施shi入ru一yi些xie經jing腐fu熟shu發fa酵jiao的de農nong家jia肥fei。如ru花hua後hou植zhi株zhu長chang勢shi不bu佳jia還hai可ke用yong0.2%磷酸二氫鉀溶液進行葉麵追肥這樣可使植株枝繁葉茂。

誤區四:花期暴曬

牡丹喜光但忌暴曬。華北地區5月yue初chu光guang照zhao就jiu已yi經jing非fei常chang強qiang了le此ci時shi正zheng值zhi牡mu丹dan的de盛sheng花hua期qi要yao進jin行xing適shi當dang遮zhe陰yin。如ru果guo陽yang光guang暴bao曬shai環huan境jing溫wen度du過guo高gao不bu僅jin會hui縮suo短duan牡mu丹dan的de花hua期qi而er且qie也ye易yi使shi盛sheng開kai的de花hua朵duo失shi去qu光guang澤ze從cong而er降jiang低di觀guan賞shang價jia值zhi。這zhe就jiu是shi為wei什shen麼me有you些xie人ren總zong抱bao怨yuan牡mu丹dan花hua期qi太tai短duan的de原yuan因yin所suo在zai。在zai華hua北bei地di區qu牡mu丹dan開kai花hua期qi間jian接jie受shou到dao早zao晨chen9點前和下午5點後的自然光照即可不僅可使開出的花朵大而鮮豔延長花期還可有效避免葉片被陽光曬傷出現焦邊等問題。
