金叶女贞生长期落叶原因和对策

发布日期:2015-05-13 00:00 来源:http://zgyiyuan.com 点击:

    金叶女贞为木樨科女贞属植物,是一种优良的彩色灌木。1999年,金叶女贞开始在江苏常武地区陆续试种,随后面积迅速增大。但从2003年起,当地金叶女贞在生长季节有少量开始落叶,呈片状斑秃,并且不断蔓延。到了2004年6月中旬,大面积金叶女贞陆续出现斑点。老叶次于幼叶出现斑点,进而发展为干枯,叶子脱落,枝条随之自上而下逐渐干枯,有少部分死亡。斑秃死亡部分大都在种植地的中间处,四周长势较好。经这几年观察,我们发现引起金叶女贞落叶的原因主要有以下两个方面。


  一、由病害引起
