花叶长虫怎么办？花叶长虫的处理方法

植物图片 2020-01-15 19:58

当花叶长虫后要根据不同的虫害进行防治，但最好要在高温的多发季节里，经常打开门窗，以增加空气的流通性，还要做好日常的清洁卫生，经常用湿布擦拭叶面，当发现虫害时要及时剪掉病株，以免感染其它枝叶。

花叶长虫的处理方法

1、注意通风

花叶在生长期间，幼期是在高温高湿的环境下最容易滋生病虫的危害，也不要将花盆放在过于封闭的环境中，这样容易通风不良产生虫害，特别是在春夏期间，室内栽培的话要经常打开门窗，以增加室内的通风透气性。

2、日常清理

如果在花卉植物的生长期间没有做好日常的卫生时，也比较容易滋生病虫害，常见的主要有蚜虫、红蜘蛛、介壳虫、蜗牛等，可在植株的生长期间定期清理盆土上的落叶，也要做好叶面的清洁卫生，要经常用湿布擦拭叶面最佳。

3、剪掉病株

剪掉病株是花叶长虫怎么办中的快捷方法，由于一旦植株的花叶上侵染了虫害时，虫类分泌的粘液会侵蚀叶片，造成真菌感染，如果不进行剪掉的话会导致植株枯萎死亡，最好当发现虫害时剪掉病株后集中销毁，以阻断虫类的繁殖能力。

4、喷洒药液

当花叶遭受到了虫害时，最有效的方法就是喷洒药物进行防治，这样可以将虫类杀死，以保证植株的正常生长，可根据不同的虫类选择不同对应的药液进行预防，还要连续喷洒，直到花叶长势好转为止。
