摘要
枣疯病是枣树的毁灭性病害,给酸枣生产带来了很大损失。深入了解河北省酸枣枣疯病的发病情况,探明影响枣疯病的发病因素和规律,对该省酸枣产业的健康发展具有重要意义。本研究采用重点调查与田间普查相结合的方法,对河北省酸枣主产区酸枣树的立地条件、周边生态、树龄、发病率、病情指数等情况进行了详细调查。结果表明:河北省太行山和燕山山区的野生酸枣均有枣疯病发生,平均发病率为10.68%,其中太行山区较燕山山区发病率高,且病情严重。河北省6个酸枣主产区的酸枣枣疯病发病率为5.67%~18.85%,地区间差异较大,其中,邯郸市酸枣的平均发病率最高,其次是石家庄(13.96%)、保定(10.85%)、邢台(8.60%)和唐山(6.15%),承德市酸枣的平均发病率最低。进一步研究表明,枣疯病的发生与周边有松、柏和泡桐的种植关系密切。总之,河北省酸枣枣疯病普遍发生,其中太行山区较燕山山区发病率高且病情严重。在酸枣园区管理及其周围绿植的选择上,应尽量避免松、柏和泡桐的种植。
Jujube witches’broom is a devastating disease of jujube,which has brought great losses to the production of wild jujube.It is of great significance for the healthy development of wild jujube industry in Hebei Province to deeply understand the incidence of jujube witches’broom and explore the factors and laws affecting jujube witches’broom.The method of combining the key investigation and field survey was used to investigate the site conditions,surrounding ecology,tree age,incidence rate and disease index of wild jujube in the main producing areas of Hebei.The results showed that jujube witches’broom occurred in wild areas of Taihang Mountain and Yanshan Mountain areas in Hebei Province,with an average incidence rate of 10.68%.The incidence rate of Taihang Mountain area was higher than that of Yanshan Mountains area,and jujube witches’broom was serious.The incidence rate of jujube witches’broom in 6 main wild jujube producing areas in Hebei was 5.67%to 18.85%,and the difference was large among regions.Among them,the average incidence rate in Handan was the highest,followed by Shijiazhuang(13.96%),Baoding(10.85%),Xingtai(8.60%)and Tangshan(6.15%),and that in Chengde was the lowest.Further research showed that the occurrence of jujube witches’broom was closely related to the planting of pine,cypress and paulownia trees around.The incidence rate of jujube witches’disease of wild jujube is generally high in Hebei.Taihang Mountain area is more serious than Yanshan Mountain area.In the management of wild jujube park and the selection of green plants around it,the planting of pine,cypress and paulownia trees should be avoided as far as possible.
