苏铁经过漫长的冬季,常会出现叶片细瘦、小叶发黄、枯焦等症状,如何处理呢? 叶片变细长,主要是光照不足引起的。苏铁虽耐阴,但在叶片生长期一定要有充足的光照。若巳发生此情况,尚有观赏价值的叶片应保留,同时将盆株移至光照充足处。若已无观赏价值,则将新叶从基部剪去,待翌年萌出新叶后再恢复。叶片上出现小叶发黄、枯焦、主要是以下原因造成的: (1)叶枯病或叶斑病危害发病时,或从小叶尖端开始褪绿变黄,并逐渐向下发展;或从小叶的中部或基部开始褪绿变黄。病斑圆 Cycas after a long winter, often appear thin leaves, leaflets yellow, Ku coke and other symptoms, how to deal with it?
