朱顶红叶子发黄可能是光照过强造成,每到夏季需做好庇荫措施,如果是浇水不当需给其更换新的土壤养殖,施肥过量灌水稀肥,使朱顶红的叶片恢复生机,遭受病虫的危害,那么将它搬移到通风处,并对其喷洒对应的药剂防治就可以了。

1、光照过强

朱顶红的叶子一年四季都是绿色的,但如果朱顶红叶子发黄,那么可能是光照过强导致,虽然它喜欢生长在充足的阳光下,但夏季很容易灼伤植株叶子,这时需做好庇荫措施,使朱顶红叶子逐渐恢复绿色生机。

2、浇水不当

朱顶红在生长的过程中,一般朱顶红叶子发黄是怎么回事呢,也可能是浇水不当造成的,如果缺乏水分那么很容易使叶子发黄,而如果大量浇水,也很容易积水烂根使叶子发黄,那么需及时的更换土壤,放在阳光下细心养护。

3、施肥过量

当朱顶红的叶片发黄也可能是施肥过量,使其植株徒长造成的,这时需给其盆土中灌浇大量的水分,使肥料从盆栽底部流出来,然后放在阳光下等待土壤晾干,再正常的给朱顶红施肥就可以了,能让朱顶红的叶子恢复色泽。

4、病虫防治

其实朱顶红也还有可能是红蜘蛛、叶斑病、黄化病造成的,这些病虫会降低朱顶红的抗病能力,使其逐渐枯萎死亡,需及时追施钾肥,并将其搬移到通风良好处,剪掉朱顶红发病的枝叶,喷洒代森锰锌、氟硅唑等药剂防治。
