虹之玉长黑虫怎么办

八公
04-09

一、发生原因

如果养殖虹之玉的地方,温度比较高,湿度比较大,而且空气流通性不佳,光照条件也不好。那么在植株的周围,就很有可能滋生一些黑色的小虫子。它们会在花土之中产卵,生出来的幼虫会啃咬植株的根系,严重影响到植株的正常生长。



二、处理方法

1、保持通风和干燥:这些小黑虫比较容易在比较郁闭而且湿度比较高的地方滋生。所以只要将植株放到通风良好的地方,然后在2-3天之内不要为植株浇水,就能够杀死大部分的虫子。



2、悬挂粘虫板:如果植株周围滋生了这种黑色的小虫,可以出购买一些黄颜色的粘虫板,然后悬挂在植株的周围。这些小黑虫会飞到板子上,然后被粘到上面。这样就能够保证植株的安全了。


3、喷洒药剂:如果想要短时间内除掉这些小黑虫,那么可以购买专用的药剂,对植株喷洒,直接杀死它们。不过这么做有可能对植株本身带来伤害,所以建议大家尽量采取前了两种方法。
