沙漠玫瑰叶子卷曲可能是遭受了蓟马虫害,要及时喷洒蚍虫林1000倍液一次即可。若是浇水过多导致新叶卷曲,就要多通风,多晒太阳。若是缺少钙肥而导致新叶卷曲发黄,要及时补充钙肥或者是骨粉。若是施肥过多导致叶子卷曲,就要停止施肥,多浇水促使新陈代谢。
沙漠玫瑰叶子卷曲的原因



1、蓟马虫害

蓟马虫害会导致沙漠玫瑰叶子弯曲。蓟马喜欢吸取嫩叶中的枝叶,所以叶子除了卷曲还有明显的伤口。但蓟马很小,肉眼不易看清,所以平常要以预防为主。若是有蓟马吸食汁液的话,就喷洒蚍虫林1000倍液一次即可,或者用烟头水杀害和预防蓟马,但这样只有一时的作用。

2、浇水过多

沙漠玫瑰不喜欢水,如若浇水过多就会导致叶子卷曲发黄。所以平常浇水的时候要确保盆土干的差不多的时候再浇。多多通风,多晒太阳,卷曲发黄的情况就会有所好转。

3、缺少钙肥

沙漠玫瑰喜欢含钙质丰富的土壤,如若土壤含钙量低,就会导致叶子卷曲,生长缓慢。针对这样就要及时补充还有钙质的肥料,情况就会有改善的,或者是加一点骨粉也可。

4、施肥过量

沙漠玫瑰不喜欢肥,若是生长期间沙漠玫瑰施肥浓度过大,或者两次施肥的间隔较小,就会肥伤导致叶子卷曲。针对施肥过多,应立即停止施肥,且不要暴晒,适当遮光,增加浇水量,促进新陈代谢,把肥料代谢掉。
