，還(hai)會(hui)影(ying)響(xiang)開(kai)花(hua)質(zhi)量(liang)。因(yin)此(ci)，春(chun)水(shui)宜(yi)早(zao)不(bu)宜(yi)遲(chi)，在(zai)早(zao)春(chun)較(jiao)好(hao)
，此(ci)時(shi)澆(jiao)水(shui)還(hai)應(ying)本(ben)著(zhe)澆(jiao)足(zu)澆(jiao)透(tou)，以(yi)土(tu)表(biao)不(bu)積(ji)水(shui)為(wei)度(du)
，不(bu)可(ke)水(shui)過(guo)地(di)皮(pi)濕(shi)；另需一提的是
，有花諺雲“幹花濕果”，也同樣適用於牡丹
，在牡丹的盛花期
，應控製澆水，如果澆水過多會縮短花期，使花朵過早凋謝。

 

    二、修剪不當：牡mu丹dan的de修xiu剪jian十shi分fen重zhong要yao，修xiu剪jian不bu當dang則ze花hua小xiao色se淡dan，影ying響xiang長chang勢shi
，修xiu剪jian得de當dang則ze花hua大da色se豔yan
，植zhi株zhu生sheng長chang旺wang盛sheng。對dui牡mu丹dan進jin行xing修xiu剪jian，一yi是shi要yao將jiang新xin生sheng的de土tu芽ya全quan部bu剪jian除chu，若ruo打da算suan用yong作zuo更geng新xin枝zhi或huo矯jiao正zheng冠guan形xing的de枝zhi條tiao則ze可ke以yi保bao留liu
，這zhe就jiu是shi花hua諺yan所suo指zhi的de“牡丹修腳”。zhexietuyaruobaoliuxialai，yishizaiqimuzhihuadeguochengzhonghuixiaohaodaliangyangfen

    三、不重視花後肥：給牡丹施肥

，一般一年三次
，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。在zai日ri常chang工gong作zuo中zhong，由you於yu種zhong種zhong原yuan因yin，往wang往wang忽hu視shi了le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施shi肥fei，會hui影ying響xiang植zhi株zhu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圈quan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。

 

    四、病蟲害防治不力：chunjisuiranbushimudandebingchonghaigaofaqi，dancishidefangzhigongzuoyebunengfangsong

，jiyishizhizhuzaishengchangqineizaoshoubingchonghaiqinxi，shenzhizhengzhusiwang。guci，zaizaochunzhanyeqianyingduizhizhupenshiyici3至5度的石硫合劑，花謝後每隔15天噴施一次50%甲基托布津可濕性顆粒1000倍液
，也可與50%多菌靈可濕性顆粒800倍液交替使用，可有效防治黑斑病、莖腐病、葉枯病等真菌類病害。春季，牡丹會遭到蚜蟲的危害
，如有發生可用敵敵畏等廣譜殺蟲劑滅殺。

 

    五、花期不遮陰：牡丹喜光但忌暴曬，在弱陰下生長最好。
