补充资料:盆花易发生的生理病害
    盆花在日常养护中,叶片上常易出现生理病害,归纳总结如下:
    1、幼叶变黄或是下部叶片卷曲萎黄,并不断脱落,往往是因为浇水过多。但需要指出的是,缺素症也易使幼叶变黄,如缺铁常使喜酸性土壤的花卉叶片变成黄白色,或叶肉变黄而叶脉仍为绿色。
    2、幼叶叶尖枯焦,多是由于光照太强,或浇水过少,或是由于空气太干燥所致。而叶子边缘卷曲,多是由于室内空气过分干燥引起的。
    3、老叶叶边缘枯焦,常是由于施肥太多而浇水不当造成的。
    4、叶子细长、脆嫩,边缘发黄变焦而脱落,多是由于光照不足,空气干燥,盆土太湿,养分不足等原因引起的。
    5、叶子上出现棕色斑或棕边现象,多是由于日灼或干旱等原因造成的,春季刚出室的花卉,新萌发的嫩叶上最易发生这种现象。
    6、突然落叶,主要是由于温度忽高忽低,光照强度变动太大造成的,有些花卉如君子兰、含笑等,日夜温差过大时,则易引起叶片脱落。(来源:中国花卉报2003-06-05)
