木槿花是一种常见的观赏植物,它叶色碧绿,花色鲜艳,观赏价值特别高,适合栽种在园林景区和庭院中。但木槿花在生产过程中,经常会出现叶子发黄的情况,它叶子发黄会影响正常生长也会影响它的观赏价值,那么是什么原因让它的叶子发黄呢?它叶子发黄以后应该怎么处理呢?
木槿花黄叶子怎么回事 木槿花叶子黄了怎么办
1、浇水不合理
木槿花是一种喜欢温暖潮湿环境的绿色植物,在它生长过程中,如果浇水不合理,就会导致它的叶子变黄,通常情况下,在木棉花正常生长时,只要保持土壤湿润就可以,如果土壤过干或者过湿,都会让它叶片发黄,这时最好的处理方法就是控制好浇水量,而且在英语高发天气中要及时做好排水工作。
2、施肥不合理
木槿花在生长过程中施肥不合理,出现时别过多或肥肉过少时,也会导致它的叶子变黄。木槿花在生长过程中施用的肥料应该以磷钾肥为主,如果它出现叶子变黄,应该辅助施用适量的氮肥。如果是因为施肥过多,导致叶子变黄,则需要及时浇水稀释肥料。
3、病虫害
病虫害的出现,也是导致木槿花叶子变黄的主要原因,有些病害在发生以后,会在叶片背面留下大量的小黑斑,严重时就会让叶片变黄,这时必须及时喷施药物,最好能喷施代森锰锌,当药物把木槿花上害虫全部消灭以后,它的叶片也会慢慢恢复到正常颜色。
4、根系受损
平时如果人们把木槿花制成盆栽,在室内养殖,就需要每年更换新的花盆,在更换花盆时,如果不小心损害了木槿花的更新,再移入新的花盆以后,也会导致木槿花的叶子变黄和脱落,这是最好的处理方法,是把木槿花放到阴凉的环境中缓苗,等它根系恢复正常以后,就会长出新的绿色叶子。
家里有阿司匹林的话可以用它溶水浇灌一下,会有所改善! 有帮助,采纳一下,谢谢
看样子应该是根出问题了,似不似你浇水多了?如果是的话,就先不要浇水了,等盆土干了以后浇一遍多菌灵和生根粉兑好的水,注意少浇。然后就等他重新发根吧。
如果不是水浇多了,可能是因为环境原因,多半是气温偏低导致的,挪到暖和的地方就可以了,但是不要离暖气太近。
黄叶可以摘下来,以免影响整颗花的颜值。
