摘要
观察到兰州21种园林树木枯萎现象,多数树种零星发病,国槐和3种绿篱灌木病株较多,约占1%。通过文献调研,认为枯萎症状与多见于热带、亚热带地区的青枯病相似,属于维管束病害。
The wilt of 21 kinds of garden trees was observed in Lanzhou.Most of the trees were sporadically affected,but there were more diseased trees in Styphnolobium japonicum and 3 kinds of hedgerows,accounting for about 1%.Through literature investigation,it is concluded that the symptoms of wilt are similar to ralstonia solanacearum in tropical and subtropical areas and belong to vascular diseases.
