发财树由于名字有着很好的寓意，所以经常被人们用来做镇宅之用。其实发财树是比较好养的一中木本类植物，但如果照顾不周，也可能会出现黄叶烂根的状况，那么，发财树烂根该怎么处理呢？下面一起学习下。

发财树烂根怎样挽救

发财树烂根怎样挽救

一、首先我们来了解下通常造成发财树烂根的原因。

1、盆内积水

发财树烂根通常都是由于盆土积水所致。盆内积水过多，根部长期处于过湿的环境中，呼吸受阻，根部会变软腐烂。如果平时浇水过多和通风不畅，会造成土壤长期潮湿，难干燥，容易积水。

2、病虫害

发财树受到病虫害的侵扰时，也会造成烂根的出现。由于水质较差，盆土较湿，极易滋生病虫，啃食根部，造成腐烂。

常见的病虫害有：白粉病、根腐病及其寄生在土壤中的根腐线虫等。

 

二、其次，要学会判断发财树是否真的烂根，免得白费力气，还把发财树伤筋动骨。

发财树烂根的症状表现：

1、叶子变黄凋落

经常有花友问：“我家的发财树叶子忽然就变黄了，而且开始大量的脱落，这是什么原因呢？”很大的可能就是您家的宝贝发财树出现了烂根现象。发财树烂根时，会阻碍正常的养分和水分的运输，从而引起叶子变黄甚至脱落。

2、树皮变软甚至脱落

所谓“人要脸，树要皮”话糙理不糙，这句话对于植物很是适用。

发财树烂根之后也会在树皮上表现出来。细心的花友可能会发现，家里的发财树树干接近树根的地方出现粘稠的分泌物，而且会出现发霉一样的白毛，用手轻碰触感发软，还会使得附近树皮脱落下来。

三、发财树烂根解决办法：

1、根部处理

当植株叶子发黄凋落，且树皮也变软时，可以肯定是烂根了。这是先把盆土扒开，让根部透透气，然后将变黄的叶子剪掉，只保留芽眼即可。待盆土干得差不多，取出木质茎，将底部的泥土弄干净。用剪刀对根系进行修剪，将腐烂部分剪掉，若腐烂严重，直接将杂乱的根系全部剪掉。

2、消毒处理

若茎也开始腐烂需要将腐烂部分清除，切成一块一块的。再将根茎放进甲基托布津或高锰酸钾溶液中，浸泡24小时；或者用速克灵喷洒伤口。然后在阴凉通风处晾干，重新栽种即可。

3、药物治疗

出现根腐病及其其他腐霉病菌活跃时，用普力克、土菌灵、雷多米尔或者疫霜灵进行喷施，通常药效在两周左右。

此外针对发财树的虫害，可以用克线磷、克线丹、米乐尔、甲拌磷等非熏蒸性杀线剂进行杀虫治疗。

如何预防烂根的发生

1、土壤保持良好透气性

想要养殖健康的发财树，需要给它提供优良的土壤基质，一定要有良好的透气性。还可以去花卉市场购买专门的园艺营养土，及其防烂防腐根颗粒。

2、养成良好的浇水习惯

浇水时养护管理中的重要环节，养护发财树时一定要严格控制水量。

发现土变成白色时即浇浇则浇透。发财树不用每天浇水，常温下可五六天浇一次，宁干勿湿。而且平时应注意花盆的卫生，如果盆地小孔堵塞，应及时疏通。
