摘　　要：柳树是榆林市主要的园林绿化树种之一,近年来,柳树丛枝病在榆林市局部地区大面积爆发,它的发生严重影响了榆林市的园林绿化景观效果。有鉴于此,本文对榆林市不同区域、不同树龄的金丝柳和旱柳进行了丛枝病发病情况调查,发现病害发生与各绿化区域建成时间有关,建成时间越早,发病越严重,并且柳树所处的生态环境结构越简单,发病率越低。最后从抗病品种选择、无菌苗圃建立、化学防治和物理防治等方面提出了综合防治方法,为掌握柳树丛枝病的发生规律及防治措施的制定提供理论依据。Willow is one of the main landscaping tree species in Yulin.In recent years,willow witches’broom has erupted on a large scale in some areas of Yulin,seriously affecting the landscaping effect of the city.This article investigates the occurrence of witches’broom disease of weeping willows and Salix matsudana Koidz.of different regions and ages in Yulin,and it is found that the occurrence of diseases is related to the construction time of the green area.The earlier construction time is,the more serious of the disease is,and the simpler the ecological environment structure is,the lower the occurrence rate is.Finally,it proposes the comprehensive control methods(including resistant cultivar selection,tree management,chemical control and physical control)in order to provide a theoretical basis for occurrence regularity and prevention of witches’broom disease of willows.
