君子兰烂根怎么处理?
君子兰烂根怎么处理,君子兰属肉质根植物,如果环境条件差或养护不当,常引起根部腐烂。一般幼苗期,常从叶基部以下腐烂,成龄植株则从根中部以下烂掉。造成君子兰烂根的原因较多,主要有:
①施肥不当。施用了未腐熟的有机肥;
②浇水过多。尤其是夏季高温和冬季室内不通风且温度较低极易引起烂根;
③盆土较差。培养土配制比例不当,使盆土板结,引起盆内长期渍水伤根;
④病菌浸染。君子兰分株时,创伤处没有消毒,使细菌侵染造成烂根。
君子兰各生长期都可能发生烂根现象,轻则株弱叶黄,重则整株死亡。如果发现烂根的植株应立即将病株从盆内磕出,轻轻剥去泥土用清水冲洗干净,再剪掉烂根,后用0.1%的高锰酸钾消毒,取出后沾少许草木灰,或用多菌灵涂抹伤口,放在阴凉处将伤口晾干,以上就是关于君子兰烂根怎么处理的介绍。
